The Catalyst switch support 1+1 redundant power supplies. The Catalyst switch support 2+1 redundant WS-C Software, Version NmpSW(8). This example shows how to set the system name on the switch: Console> (enable) set system name Catalyst System name set. Catalyst > (enable). Software Guide. Cisco WS-C - Catalyst Chassis Switch Software Catalyst family switches—Refers to the Catalyst SPLASHTOP STOP DISPLAY ON REMOTE
This example shows how to display the Cisco Systems Console Telnet login banner content:. You can use the set alias command to define command aliases short versions of command names for frequently used or long and complex commands. Using command aliases can save you time and help prevent typing errors when you are configuring or monitoring the switch. For the name argument, specify a name for the command alias. The parameter argument is the text the user types at the command line to activate the command.
To define a command alias on the switch, perform this task in privileged mode:. These examples show what happens when you enter the command aliases at the command line:. You can use the set ip alias command to define aliases for IP addresses. IP aliases can make it easier to refer to other network devices when you use ping , telnet , and other commands, even when DNS is not enabled. For the name argument, specify a name for your IP alias.
This example shows how to define two IP aliases, sparc , which refers to IP address This example also shows how to verify the currently defined IP aliases:. This example shows what happens when you use the IP aliases with the ping command:. You can configure an ARP entry so that it does not age out, by configuring it as either static or permanent.
When you configure a static ARP entry using the set arp static command, the entry is removed from the ARP cache after a system reset. When you configure a permanent ARP by using the set arp permanent command, the ARP entry is retained even after a system reset. Because most hosts support dynamic resolution, you usually do not need to specify static or permanent ARP cache entries. When a device does not respond to ARP requests, you can configure an ARP entry to be statically or permanently entered into the ARP cache so that those devices can still be reached.
To configure a static or permanent ARP entry, perform this task in privileged mode:. Clear a dynamic, static, or permanent ARP entry. This example shows how to clear all permanent ARP entries and verify the configuration:. Note For information on configuring a default gateway default route , see the "Configuring Default Gateways" section. In some situations, you might need to add a static routing table entry for one or more destination networks.
Static route entries consist of the destination IP network address, the IP address of the next-hop router, and the metric hop count for the route. In software release 5. You can specify the subnet mask for a destination network using the number of subnet bits or using the subnet mask in dotted decimal format. If no subnet mask is specified, the default classful mask is used. The switch uses the longest-match network address in the IP routing table to determine which gateway to use to forward IP traffic.
In releases prior to software release 5. The switch forwards IP traffic that is generated by the switch using the longest address match in the IP routing table. The switch does not use the IP routing table to forward traffic from connected devices. In software releases prior to software release 5. This example shows how to configure a static route on the switch and how to verify that the route is configured properly in the routing table:.
You can use the reset at command to schedule a system to reset at a future time. This feature allows you to upgrade software during business hours and schedule the system upgrade after business hours to avoid a major impact on users. You can also use the schedule reset feature when trying out new features on a switch. To avoid misconfiguration or the possibility of losing network connectivity to the device, you can set up the startup configuration feature and schedule a reset to occur in 30 minutes.
You can then change the configuration, and if connectivity is lost, the system will reset in 30 minutes and return to the previous configuration. You can specify an absolute time and date at which the reset will take place, using the reset at command. The month and day argument is optional. If you do not specify a month and day, the reset will take place on the current day if the time that is specified is later than the current time.
If the time that is scheduled for reset is earlier than the current time, the reset will take place on the following day. Note The maximum scheduled reset time is 24 days. To schedule a reset at a specific time, perform this task in privileged mode:. This example shows how to schedule a reset at a specific time and include a reason for the reset:.
You can schedule a reset within a specified time with the reset in command. For instance, if the current system time is a. If you or NTP advances the system clock to a. If the clock is advanced ahead of the scheduled reset time, the reset will take place 5 minutes after the command is issued.
To schedule a reset within a specified time, perform this task in privileged mode:. Note The minimum downtime argument is valid only if the system has a redundant supervisor engine. The next three sections describes the power management feature in the Catalyst family switches. You can select from several different power supplies to ensure that you have enough power for the modules installed in your switch. The Catalyst series switches support the following power supplies:. When you insert power supplies in your switch, use power supplies that are of the same wattage.
If you mix power supplies, the switch will use the one in power supply bay 1 PS1 ; the power supply in power supply bay 2 PS2 is ignored. The power supply status is displayed as err-disable in the output for the show system command. This example shows the output for the show system command for mixed power supplies:. If the primary power supply fails, the second power supply immediately supports the switch without any disruption in the network.
Both power supplies must be the same wattage. A single power supply must have enough power to support the switch configuration. However, combined mode has no power redundancy. If a power supply fails, one or more modules might shut down. Combined mode requires that your switch have two power supplies.
By default, a switch is set to redundant mode. In the show environment power command, if the power budget is 1, the switch is in redundant mode; if the power budget is 2, the switch is in combined mode. Your switch hardware configuration will dictate which power supply or supplies you should use.
For example, if your switch configuration requires more power than a single power supply provides, use the combined mode. In combined mode, however, the switch has no power redundancy. Consider the following possibilities:. This configuration will require W of inline power plus W for the modules.
It is possible that you can configure a switch that requires more power than the power supplies provide. The two ways you could configure a switch to exceed the power capabilities are as follows:. If you insert a single power supply and then set the switch to combined mode, the switch displays this error message: Insufficient power supplies present for specified configuration.
This error message is also displayed in the output for the show environment power command. This error message is displayed because combined mode requires two working power supplies in the switch. If you have only one power supply in the switch, and the switch is set to combined mode, the switch will place each module in reset mode. If the power requirements for the installed modules exceed the power that is provided by the power supplies, the switch displays this error message: Insufficient power available for the current chassis configuration.
This error message also appears in the show environment power command output. If you attempt to insert additional modules into the switch and exceed the power that the power supplies provide, the switch immediately places the newly inserted module into reset mode and the switch displays these error messages: Module has been inserted and Insufficient power supplies operating.
If you power down a functioning switch, and you insert an additional module or change the module configuration so that the power requirements exceed the available power, once you power on the switch again one or more modules are placed in reset mode. If you have too many IP phones drawing power from the system, power to IP phones is cut and some phones may be powered down to reduce the power requirements to match the power supplies.
A module in reset mode continues to draw power as long as it is installed in the chassis. To compute the power requirements for your system and verify that your system has enough power, add the power consumed by the supervisor engine module s , the fan box es , and the installed modules including inline power. For inline power, multiply the number of IP phones by 6.
See the "Power Consumption for Modules" section for more information on the power consumption for the various components of your switch. By default, the power supplies in a Catalyst series switch are set to operate in redundant mode. To effectively use redundant mode, follow these guidelines:. Variable power supplies automatically adjust the power resources to accommodate the chassis and inline power requirements when a system is booted up. Modules are brought up first, followed by IP phones.
To configure redundant mode on the Catalyst series switch, perform this task in privileged mode:. If your switch configuration requires more power than a single power supply can provide, set the power management mode to combined mode. Combined mode utilizes the available power for both power supplies; however, the switch will have no power redundancy. Variable power supplies automatically adjust the power resources to accommodate the chassis and inline power requirements.
The power supplies have a predetermined current sharing ratio. See Table for more information. If you set the power budget to 2, the switch disregards this setting. Only system power increases with combined mode. To configure combined mode on the Catalyst series switch, perform this task in privileged mode:.
Table lists the power that is provided by the Catalyst series switches power supplies. When the switch is configured to combined mode, the total available power is not the mathematical sum of the individual power supplies. Keep in mind the following guidelines when using a W DC power supply with your Catalyst series switch. The DC input can vary from W to W. Refer to the power supply documentation for additional information.
If you set the power budget to 2 Combined mode , the switch disregards the setting, and remains in Redundant mode. Although inline power is percent efficient, system power has only 75 percent efficiency. For example, each W of system power requires W from the DC input. The power supply fan status was tied to the power supply status so that the status of the inline power switch can be reported to software.
Therefore, if the power supply fan fails, the display shows the power as faulty, even though the main power is working properly. The power management feature for the Catalyst series switch can support an optimized Catalyst chassis with a limited module configuration on a reduced number of power supplies.
In systems with redundant power supplies, both power supplies should be of the same wattage. If you mix a W power supply and a W power supply, the switch performs as if there were two W power supplies. For detailed information on supported power supply configurations for each chassis, refer to the Catalyst Family Switch Installation Guide. In those configurations, redundancy requires three power supplies.
Redundant and nonredundant power configurations are discussed in the following sections. The Catalyst switch contains holding bays for up to three power supplies. You need two primary power supplies to operate a fully loaded Catalyst chassis. The workaround is to reboot the switch. This problem is resolved in software release 5. An active path is a SA, DA pair. Reordered packets may cause SNA sessions to drop. There is no workaround.
This section describes open caveats in Catalyst family software release 4. This problem is resolved in software releases 4. This usually happens if you have set the screen length to 0 and long show commands are being displayed or if you have cut and pasted several show commands onto the window. The workaround for this problem is to avoid using cut and paste in a Telnet session and setting the screen length to nonzero.
Packets are forwarded correctly. Port operation is not affected. In order to determine the actual number of FCS-Errors on valid length packets received on the port, subtract the value of the port Runts counter from the value of the port FCS-Error counter.
The workaround is to press the q key. For more information on this error message, capture the output from the following commands before you reset the switch and provide this information to your TAC representative:. These messages are caused by the default Token Ring VLAN configuration, which is always present regardless of the specific configuration of the switch.
To provide more information on this error message, the development engineer will add a dump in software release 4. If you are on a switch that receives this message, capture the output from the following commands before you reset the switch. If you TAC can get into engineering mode, use lcp 1 show vbuf.
This does not happen in normal use. Note For a description of caveats resolved in software release 4. These messages are caused by the default Token-Ring VLAN configuration, which is always present regardless of the specific configuration of the switch. Note Open caveats in software release 4.
The workaround is to clear all dynamic CAM entries using the clear cam dynamic command, or wait for the entry to age out if no traffic from that address is received by the switch. When the update timer in one VTP client times out, it has to send a request advertisement but this request does not reach other clients and the requesting client remains stuck waiting for the rest of the configuration.
Resetting the switch or changing the state of the switch enables the hung client to learn the configuration. The workaround is to issue a clear snmp trap all command and reenter the valid SNMP trap receivers. The workaround is to reduce the traffic load and reset the module. This problem is fixed in software release 4. This message indicates that a port for a given VLAN has been added to the spanning tree in a disabled state.
Examine the condition of the port. Contact your technical support representative. These messages have been moved to severity level 7 in software release 4. Multiple default gateways are not supported. The If the uplink port is on one module for example, module 2 , hosts connected to the other module for example, module 3 will not notice a decrease in convergence time. As a result, the system name in the show system command output and the command line prompt do not reflect the system name.
The workaround is to disable RMON, not configure any RMON alarms on the switch, or increase the polling interval of the alarm such as one poll every five minutes. The workaround is to make sure Novell servers use However, a related caveat CSCdm is still open in software release 4.
For more information, see the "Open Caveats in Software Release 4. The workaround is to delete the problem etherStatsEntry and create a new one. The workaround is to set the default facility severity level to a value equal to or greater than the configured syslog severity level. In release 4. The workaround is to connect to a different port on the remote device if the problem occurs. If the problem occurs, reset the module with the problem SPAN port.
For example, if the sc0 IP address is However, a ping to an address in any other Class B network succeeds. Events that cause the switch to clear dynamic CAM entries include:. If you reset the module and some or all of the ports fail to come up, reset the module a second time. If ports still do not come up, remove and reinsert the module. If there have been no transmit queue drops, the value is correct no drops occurred. However, if there have been drops, the counter might show an incorrect nonzero number.
In addition, the counter might decrement or display a very large number. To recover, reset the switch. The correct behavior is that the channel is torn down and renegotiated. Specifying a repeat count greater than 16 might cause the ROM monitor to reset the system. Some of these options such as VLAN membership affect all four ports while the channel is established, but if the channel breaks, the change is only retained on the first two ports.
The workaround is to turn off channeling on the ports, make the desired configuration changes, and then return the channeling configuration to its original state. This problem does not affect the functionality of port security or the static CAM entries. The problem does not occur if you remove the module with the power on. The workaround is to manually set the desired sc0 IP address.
Alternately, you can clear the entire switch configuration using the clear config all command make sure you back up your switch configuration before entering this command or your configuration will be lost. The workaround is to configure a different IP address and subnet mask for the me1 interface. The workaround is to configure the me1 interface Down and then Up using the set interface command.
The workaround is to configure the unused interface Down and assign it an IP address in a different subnet. If subnet routes are still assigned to the wrong interface, manually configure the active interface Down and then Up using the set interface command. The workaround is to set the native VLAN of the trunk port to VLAN 1 permanently fixing the problem or reset the module on which the trunk port is located you will have to reset the module again each time the switch boots.
If multiple ports share an ifIndex value, when you change the configuration on one port, other ports with the same ifIndex value might be affected. If this problem occurs, clear the entire switch configuration using the clear config all command make sure you back up your switch configuration before entering this command or your configuration will be lost and reset the switch. However, the show trunk command output shows the port is still trunking.
The correct trunking state is displayed for the port after a reset. The workaround is to explicitly specify the broadcast address when you enter the set interface command when using a nonbit boundary subnet mask. The workaround is to clear the CAM table using the clear cam dynamic command after enabling protocol filtering or setting the protocol filtering mode of a port to auto.
This MAC address is illegal, but some noncompliant hardware might advertise this address. The workaround is to not enter the show cam dynamic command if a MAC address of all zeroes has been learned. Communication over the in-band interface might be lost. These sections provide usage guidelines, restrictions, and troubleshooting information for Catalyst family switch hardware and software:. This section contains usage guidelines, restrictions, and troubleshooting information that apply to the supervisor engine and to the switch at the system level.
Otherwise, in some situations, a broadcast storm can occur. The workaround is to reduce the sample interval. The counter value is not maintained for each port; instead, the value is maintained for the entire switch. Do not use the set portfast command on a trunk port. In addition, designating a port as a trunk port ignores the PortFast feature for the port.
This section contains usage guidelines, restrictions, and troubleshooting information that apply to modules and switch ports. Incorrectly inserting a module can cause unexpected behavior. For proper module installation instructions, refer to the Catalyst Series Installation Guide. Note You must specify a valid port range when entering the set port channel command.
You cannot specify a single port. If the other device is not set to autonegotiate, the Catalyst autonegotiating port will remain in half-duplex mode, which can cause a duplex mismatch resulting in packet loss, late collisions, and line errors on the link. Reconfigure the port-duplex setting and use the set port enable command to reenable the port. Alternately, you can configure both ports to a fixed-value port speed and full duplex. On a blocked port, the Catalyst family switch receives spanning tree bridge protocol data units BPDUs periodically from the neighboring device.
You can configure the frequency with which BPDUs are received by entering the set spantree hello command the default frequency is set to two seconds. If a Catalyst family switch does not receive a BPDU in the time period defined by the set spantree maxage command 20 seconds by default , the blocked port transitions to the listening state, the learning state, and to the forwarding state.
As it transitions, the switch waits for the time period specified by the set spantree fwddelay command 15 seconds by default in each of these intermediate states. Therefore, a blocked spanning tree port moves into the forwarding state if it does not receive BPDUs from its neighbor within approximately 50 seconds. The following usage guidelines, restrictions, and troubleshooting information apply to spanning tree:.
You can use the show spantree summary command and this formula to compute the total number of logical ports on the switch:. Note Count each port in an EtherChannel port bundle independently do not count the bundle as a single port. In order to recover from an extended broadcast storm caused by a faulty device in a network, Catalyst family switches reset blocked ports.

The problem might occur after you do the following:. After you perform the preceding steps, the switch might respond that the account is disabled for both valid and invalid passwords after you try to enter the enable mode. After repeated attempts, the switch might go into an idle state and then reset.
In software release 8. Workaround : If you want to retain the auto-learned addresses, enable the set port security auto-configure option. Workaround : Upgrade to the Catalyst system software image catk8. Workaround : Disable and re-enable the failing port.
There is no workaround. This is caused by an incorrect PHY initialization sequence. The error rate is well below IEEE specifications and does not cause an observable difference in performance due to the occasional CRC errors.
Workaround : Replace the cable with one that is greater than 9 feet long greater than 3 meters. Workaround: Disable and enable the port. Workaround: To successfully log in, enter any value as a username, and use the switch enable password as the password for authentication. Workaround : Configure the port for autonegotiation. There should be a second delay before traffic gets forwarded.
Diagnostics have been added to identify the problem. Once the problem is identified, the switch automatically resets and comes back up in a "best-effort" mode. In the "best-effort" mode, the affected packet buffers are removed from circulation, and log messages are generated every 30 minutes to warn about the failures.
You should replace a supervisor engine if it has packet memory errors. Workaround: Turn off autonegotiation using the set port speed command. In most cases, this message is caused by ARP requests from the switch being flooded back to itself by a neighbor. If the switch reaches a condition that the same MAC address is learned on dynamic and static CAM, enter the clear port security and clear cam dynami c commands to clear the MAC address from the dynamic CAM and reach a "consistent" state.
Communication is lost in approximately 15 seconds. This problem occurs when the original root port comes up after a switchover. Workaround: Change all dynamic memberships to static and then back to dynamic. This action causes the next command that you enter to merge with this command.
After you have recovered the session, you need to move the sc0 interface into a different VLAN to avoid this problem in the future. If you attempt to configure Idledetect in the CLI, the switch ignores the configuration. Initially, the dynamic VLAN for the port works, but after the port links goes up and down 50 times, the port stops working.
The port displays as a connected port but the status will be inactive. This condition results in lost communication because the switch does not clear the older MAC table on the root port. This is an information message only and should not affect the operation of your switch. Workaround: Set the maximum addresses allowed to a higher value and then enter the clear port security all command. If the echos are not answered, the broadcast renews the DHCP address.
This situation can cause a STP loop in the network. If you enter an incorrect username, the switch prompts you for password three times before disconnecting. Private VLANs cannot be assigned to dynamic ports. Software release 7. An affected network device, running an SSH server based on the OpenSSH implementation, may be vulnerable to a Denial of Service DoS attack when an exploit script is repeatedly executed against the same device.
There are workarounds available to mitigate the effects of these vulnerabilities. This behavior is also observed after you reset the switch. Workaround: If the IP phone receives PoE, remove the phone from the network, to power cycle the phone. Workaround : Reset the switch. It returns the format of the command structure. Workaround : Configure the port first to auto, and then to When this situation happens, some data packets are looped back while the port transitions to a blocking state.
This may cause network problems if port security is enabled on the port, because the switch secures the looped MAC addresses and restricts the traffic from the original unsecured port. This situation resulted in a security violation. Workaround : Reconfigure the duplex speed to half, and then change it back to full. Workaround : Reenable the port. This situation causes flooding on the primary VLAN.
This memory leak presents itself in one of two ways:. You can use the show proc mem command to view the memory held by processes and verify if you have a memory leak. This section provide usage guidelines, restrictions, and troubleshooting information for Catalyst series switch hardware and software. This section contains usage guidelines, restrictions, and troubleshooting information that apply to the supervisor engine and to the switch at the system level:.
Refer to the Catalyst and Switch Installation Guide for detailed information about power requirements for the Catalyst series switches. If you specify a port name that contains more than 18 characters the last characters will not be displayed in the output. Use the all keyword to display both the default and nondefault configurations for example, show config all.
Otherwise, in some situations, a broadcast storm can occur. The counter value is not maintained for each port; instead, the value is maintained for the entire switch. Do not use the set portfast command on a trunk port.
In addition, designating a port as a trunk port causes the PortFast feature to be ignored for the port. ICMP entries are stored in mbuf memory. When too many ICMP entries are learned, they use up crucial resources and cause the switch to reset.
Configure static routes for the required destinations using the set ip route command. This section contains usage guidelines, restrictions, and troubleshooting information that apply to modules and switch ports:. If you receive this message, issue the command show port counters and check each port for excessive error frames, such as collisions, runts, and transmit errors.
Incorrectly inserting a module can cause unexpected behavior. For proper module installation instructions, refer to the Catalyst and Switch Installation Guide. Reconfigure the port-duplex setting and use the set port enable command to reenable the port. The following modules have the same configuration type:. Or, you can configure both ports to a fixed-value port speed and full duplex. In supervisor engine software release 5. This command automatically enables PortFast and sets the trunking and channeling modes to off.
In software releases prior to release 5. Note You must specify a valid port range when entering the set port channel command. You cannot specify a single port. This example shows how to configure a port for end station connectivity using the set port host command:. This example shows how to manually configure a port for end station connectivity:. There is no restriction if the violation mode is set to shutdown ; you can enable protocol filtering on the switch. If the other device is not set to autonegotiate, the Catalyst series autonegotiating port will remain in half-duplex mode, which can cause a duplex mismatch, resulting in packet loss, late collisions, and line errors on the link.
Multiple module resets should be avoided. This section contains usage guidelines, restrictions, and troubleshooting information that apply to spanning tree:. On a blocked port, the Catalyst series switch receives spanning tree bridge protocol data units BPDUs periodically from the neighboring device. To configure the frequency with which BPDUs are received, enter the set spantree hello command the default frequency is set to two seconds.
If a Catalyst series switch does not receive a BPDU in the time defined by the set spantree maxage command 20 seconds by default , the blocked port transitions to the listening state, the learning state, and to the forwarding state. As it transitions, the switch waits for the time period specified by the set spantree fwddelay command 15 seconds by default in each of these intermediate states.
Therefore, a blocked spanning tree port moves into the forwarding state if it does not receive BPDUs from its neighbor within approximately 50 seconds. In order to recover from an extended broadcast storm, Catalyst family switches must reset blocked ports. To ensure recovery, all Catalyst family switches in the network should reset blocked ports at the same time, by sending synchronization packets on VLAN 1.
A Catalyst family switch will not send synchronization packets unless it is the root bridge. We recommend that you leave spanning tree enabled on the native VLAN of an If you plan to disable spanning tree in an On a blocked spanning tree port, check the duplex configuration to ensure that the port duplex is set to the same type as the port of the neighboring device. If the Rcv-Frms counter is incrementing but the Rcv-Multi counter is not, then this port is receiving nonmulticast frames but is not receiving any BPDUs.
You can use the show spantree summary command and the following formula to compute the sum of logical ports on the switch:. The sum of all logical ports, as calculated with the formula above, should be less than or equal to the following:. Note Count each port in an EtherChannel port bundle independently do not count the bundle as a single port. Although the show spantree command displays PortFast as enabled on a trunk port, PortFast has no effect on such ports.
If these errors are incrementing continuously, the port might drop input BPDUs. This problem can also cause the port to drop incoming BPDUs. Therefore, VTP client and server switches might not synchronize if they are separated by a VTP transparent switch with no domain name configured. To avoid connectivity problems, follow these guidelines:. The nonegotiate keyword transitions a link into trunking mode without sending DTP frames.
If you configure Catalyst CSR subinterfaces to a trunk using Verify the native VLAN assignment for the trunk using the show trunk command. This problem is tracked as a defect against the Catalyst CSR software. The time increases with the number of VLANs on the trunk.
During this time, you might see unexpected behavior, such as the console hanging or other ports not going into forwarding. After the trunks become operational, the unexpected behavior disappears and operation returns to normal. The operation remains normal as long as the trunks remain operational. This section contains usage guidelines, restrictions, and troubleshooting information that apply to Fast and Gigabit EtherChannel:. During this interval, the port does not appear in show spantree command output.
If it takes more than ten minutes for a channel to form and appear on spanning tree, disable and reenable the ports. In addition, it might take up to two minutes to unbundle a channel after changing the channel mode. We recommend that you reenable the ports by entering the set port enable command, and configure the two ports with one of the following valid EtherChannel configurations:.
This is the expected behavior when a static CAM filter exists in the host table. Filter action takes precedence over copying the traffic to a sniff port, and hence these packets will not be accounted for in the sniffed traffic statistics. You can enable it using the set span command with the inpkts enable keywords. This section contains usage guidelines, restrictions, and troubleshooting information that apply to multicast protocols and traffic on the switch:.
To enable CGMP leave processing, enter the set cgmp leave enable command. The reserved IP multicast addresses, in the range This section contains usage guidelines, restrictions, and troubleshooting information that apply to authentication, authorization, and accounting AAA :. This behavior is related to CSCdx With the CSCdx fix, the user privilege level is set based on the privilege level at which the user is authenticated.
For example, if a user attempts a login authentication, the privilege level is 1. If the user attempts an enable authentication, the privilege level is When you press the Enter key and then type your password with the user priv-lvl hard coded to 15, the switch responds as if this is a login authentication as a regular password attempt.
When you press the Enter key and then type your password with the user priv-lvl hard coded to 11, the switch responds as if you are changing your password. This section contains usage guidelines, restrictions, and troubleshooting information that apply to power management and PoE. During this time, if you remove the powered device and insert a different powered device, the switch software does not notice that you have changed the powered device.
The new powered device is not detected and remains in the power-deny state. The switch immediately applies power to PoE ports as soon as each module comes online and does not wait for all modules to come online before applying power. As each module comes online, power is applied to the static ports and then the auto ports for that module. If you exceed the total available PoE before all modules come online, the ports in the module that come online later may not receive power.
The initial power allocation can vary depending on which discovery method succeeds first. If the IEEE discovery method discovers the powered device before Cisco proprietary method, the initial power allocated to the powered device will be the defined by the upper limit of the discovered IEEE class. If the Cisco discovery method succeeds first, the initial power allocated to the powered device will be equal to he amount you specified with the set inlinepower defaultallocation command.
In previous software releases, the power consumed and power allocated were converted from mAmps and converted to Watts. This section contains usage guidelines, restrictions, and troubleshooting information that apply to nonembedded CiscoView:. Another workaround is to right-click on the chassis and select Resize to decrease the size of the chassis view.
To correct the problem, upgrade to Java Plug-in 1. Note Java Plug-in versions 1. Make sure that you are using Netscape Communicator 4. Step 1 Uninstall the current Java Plug-in from your machine. Step 2 Download the Java Plug-in from the following location and install it:.
Step 5 Launch Netscape Navigator. Step 7 Make sure the "Enable Java" check box is not selected. The Java console is displayed, but the chassis view does not appear. Step 10 Select the "Enable Java" check box. Both the Java console and chassis view should be displayed. To correct the problem, download Java Plug-in 1. Workaround: Close and reopen the EtherChannel dialog box. The workaround is to close and reopen the dialog box and then delete the primary VLAN.
You should now see the correct error message: "The Primary is bounded The following error message is displayed:. The correct message will then be displayed. The following documents are available for Catalyst series switches:. Cisco documentation and additional literature are available on Cisco.
