Release Notes for Catalyst 6500 Series Content Switching Module Software Release 2.2(8)
78-12569-16
Caveats
– Unknown real servers with unknown bind IDs and weights show up.
– Virtual servers send an RST to all connection requests.
– CSM performance becomes very slow.
Workaround: Do not configure both a DFP agent and a manager on the CSM while it is balancing
traffic.
• CSCdu38154
Under a heavy FTP connection load you may see warnings about FTP not finding associated
sessions. These messages are benign.
Workaround: None.
• CSCdu46347
If you change the server farm VLAN IP address while the ICMP probe is configured, the ICMP
probe still uses the old IP address instead of the new one. Changing the server farm with ICMP
causes probes to fail and eventually brings the virtual server out of service.
Workaround: Delete the ICMP probe from the server farm configuration, change the VLAN IP
address, and then add the ICMP probe back to the server farm configuration.
Note Multiple server farms may be associated with a VLAN IP address. To determine which server
farms are associated with a VLAN IP address, issue the show ip slb real command, examine the
display, identify the real servers that are in the same network as the VLAN IP address, and note
the server farm associations of those real servers.
• CSCdu54735
If the version of software running on the CSM does not correspond to the version of Cisco IOS
software running on the Catalyst switch, a spurious memory access message may be displayed when
the CSM is inserted into a Catalyst 6500 Series chassis.
Workaround: If the versions of software do not correspond, either the Cisco IOS or the CSM
software must be upgraded for the module to function.
• CSCdv78416
When using the no ip slb map command (or no map in the module CSM submode) in Cisco IOS
software for the CSM, the memory allocated for match rules is not deallocated. This condition is not
usually a problem since the amount of memory required is small. Additionally, calling the no
url-map, no cookie-map, or no header-map command from SLB policy submode can cause the
specified map to be associated with the policy, rather than disassociated, if the policy is not currently
associated with a map of that type.
Workaround: Do not call the command for a policy that is not configured with a map of the given
type.
• CSCdw47284
Client access lists for the CSM are specified in one of two ways:
– If the list is assigned directly to the virtual server using the client command in the vserver
submode, the client mask will be changed to 255.255.255.255 during a configuration reload,
which occurs when the configuration is first sent to the module on startup.
– When using the clear ip slb linecard-config command.
