Resolved Caveats

CSCsg28558 Cisco X2-10GB-CX4 transceiver modules with a version identification number lower than V03 might be difficult to install because of a size discrepancy. The workaround is to use modules with a version identification number of V03 or later.

CSCsg91027 When the logging event-spanning-tree interface configuration command is configured and logging to the console is enabled, a topology change might generate a large number of logging messages, causing high CPU usage. CPU usage can increase with the number of spanning-tree instances and the number of interfaces configured with the logging event-spanning-tree interface configuration command. This condition adversely affects how the switch module operates and could cause problems such as STP convergence delay.High CPU usage can also occur with other conditions, such as when debug messages are logged at a high rate to the console. Use one of these workarounds:

–Disable logging to the console.
–Rate-limit logging messages to the console.
–Remove the logging event spanning-tree interface configuration command from the interfaces.

CSCsz18634 On a switch running Cisco IOS release 12.2(46)SE, the output of the show interfaces privileged EXEC command shows 0 packets for port channel input and output rates. The workaround is to reload the switch by entering the reload privileged EXEC command.

CSCtb58779 When a switch is low on memory (less than 256 MB), it can reload and display a SYS-2-WATCHDOG error. There is no workaround. Enter the show memory debug leak privileged EXEC command to check for signs of a memory leak and address these symptoms.

CSCtc02635 On switches running Cisco IOS release 12.2(50)SE3 running MAC authentication bypass with multidomain authentication (MDA, IP phones connected to a port might not be able to regain network connectivity in the VOICE domain if the session times out and all RADIUS servers are unreachable. There is no workaround.

CSCtc38519 (Catalyst 3110G and 3012 switches) Attempts to restore factory default settings from the advanced Management Module (aMM) web interface fail. After the switch restarts, the configurations are not erased and restored to their factory default settings. Switches that run Cisco IOS Release 12.2(50)SE or Release 12.2(52)SE are affected. Workaround: Enter the write erase privileged EXEC command from the switch console, do not save the configuration from the switch console, and then restart the switch.

CSCtc57809 Switches running Cisco IOS Release 12.2(52)SE might reload after you enter the no mac address-table static mac-address vlan vlan-id interface interface-id global configuration command if the interface is up and the MAC address was dynamically learned before it was changed to static. Use one of these workarounds: –Clear the dynamic MAC address table when configuring static MAC addresses as in this example: Switch(config)# no mac address-table learning vlan vlan_id Switch(config)# clear mac-address-table dynamic address mac_address Switch(config)# mac address-table static mac_address vlan vlan_id interface interface_id Switch(config)# mac address-table learning vlan vlan_id –Downgrade to Cisco IOS Release 12.2(50)SE. –Upgrade to Cisco IOS Release 12.2(53)SE if available.

CSCtc77969 When PAgP or LACP EtherChannels are configured on a switch and the stack reloads, entering a show interface or show etherchannel summary privileged EXEC command when the stack comes up can cause the console to lock up. There is no workaround.

CSCte72365 After a software upgrade from Cisco IOS Release 12.2(52)SE to Cisco IOS Release 12.2(53)SE, EIGRP hello packets are flooded on access ports belonging to another subnet. The same result occurs when you initiate ping requests to the broadcast address of other subnets. This results in Not on common subnet errors on the other side of the link. The workaround is to downgrade to 12.2(52)SE

CSCtc02635 On switches running Cisco IOS release 12.2(50)SE3 running MAC authentication bypass with multidomain authentication (MDA, IP phones connected to a port might not be able to regain network connectivity in the VOICE domain if the session times out and all RADIUS servers are unreachable. There is no workaround.

CSCtc38519 (Catalyst 3110G and 3012 switches) Attempts to restore factory default settings from the advanced Management Module (aMM) web interface fail. After the switch restarts, the configurations are not erased and restored to their factory default settings. Switches that run Cisco IOS Release 12.2(50)SE or Release 12.2(52)SE are affected. The workaround is to enter the write erase privileged EXEC command from the switch console, do not save the configuration from the switch console, and then restart the switch.

CSCtd29049 A switch that has at least one trunk port configured might fail when you configure more than 950 VLANS by using the vlan vlan-id global configuration command. There is no workaround.

CSCte99016 When two blade switches in a blade server are running Cisco IOS release 12.2(53)SE, with no stack cable connection between them, if you enter the no shutdown interface command on gigabitethernet ports 1/0/17 and 1/0/18, the output of the show running-config or show interface privileged EXEC command shows the ports to be down. The workaround is to downgrade the software to Cisco IOS Release 12.2(52)SE.

CSCtf17223 If you try to access the Web-based device manager from the IBM AMM, the switch incorrectly reports to the IBM blade center chassis that it supports only https and does not support http.When you access device manager from the AMM, the URL link is always https://. The workaround is to manually change it to http:// in the browser.

CSCtg88183 The switch internally uses the mac-address-table static mac-address deprecated global configuration command to configure the MAC address on the Ethernet management port (Fa0). The workaround is to use the correct version of the command: mac address-table static mac-address.

Resolved Caveats

•CSCsx97605
The CISCO-RTTMON-MIB is not correctly implemented in this release.

•CSCtb08823
SNMP requests on the stpxRSTPPortRoleTable object only return information for the stack master. There is no workaround.

•CSCtb10158
A switch can fail when an SNMP process attempts to configure dot1x authentication when it is already configured. There is no workaround.

•CSCtb25230
When a switch stack is configured with DHCP snooping enabled on the host VLAN, hosts connected to the stack master receive bootp packets, but the a packet might not be forwarded to the end hosts connected to stack member switches. The behavior depends on which interface in the stack received the packet. The workaround is to disable DHCP snooping for the affected VLAN.

• CSCtc43231
A switch does not receive SNMP trap and inform messages from the correct interface after you have entered the snmp-server trap-source loopback0 and snmp-server source-interface informs loopback0 global configuration commands. There is no workaround.

•CSCtc59162
Modifying a prefix list that is configured as an inbound or outbound distribute-list causes the EIGRP peer to resynchronize.

•CSCtc71798
Traffic received on a member interface of a cross-stack EtherChannel is dropped from a switch stack. In previous releases, this intermittently occurred after a reload of the stack.

•CSCte46127
You cannot enable EtherChannel on port 14 of the IBM blade. There is no workaround.

• CSCte52821
When you enter the no ip ftp passive global configuration command to allow all types of FTP connections on a switch running Cisco IOS Release 12.2(52)SE or 12.2(53)SE, FTP sessions could disable Telnet or console connections. Then you can no longer use the vty. Workaround: When you cannot use the vty, restart the switch. To prevent FTP sessions from disabling Telnet or console connections, enter the ip ftp passive global configuration command.

•CSCte67201
On a switch that is configured for IP routing and that is running Cisco IOS Release 12.2(50)SE or later, Cisco Express Forwarding (CEF) can use a large amount of memory. The IP RIB Update process uses about 2000 bytes for each prefix that CEF uses. There is no workaround. You can reduce the memory use by reducing the number of routes the switch processes.

•CSCte72365
After upgrading from Cisco IOS Release 12.2(52)SE to Cisco IOS 12.2(53)SE, EIGRP hello packets are flooded on access ports belonging to other subnets. This also occurs when pings are sent to the broadcast address of other subnets
