Caveats

• CSCdv00464

Issuing the clear interface gigabit slot/port command for a CSM gigabit port may not clear the

counters.

Workaround: None.

• CSCdv11685

Do not configure different fault-tolerant pairs to use the same FT VLAN.

Workaround: Use a different FT VLAN for each fault-tolerant CSM pair.

• CSCdv29125

In firewall configurations using an HTTP 1.1 redirect virtual server, a connection going through the

firewalls may remain open after a redirect virtual server connection is established.

Workaround: None. This connection closes when it times out.

• CSCdv73302

When serverfarms for the CSM have been configured with health probes and no real servers at the

time the module comes online, the probe configuration for the serverfarm is never sent to the

module, even when the real servers are later added to the serverfarm.

Workaround: Configure real servers before configuring probes in ip slb serverfarm submode.

• 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.

• CSCdw09585

When two CSMs are configured as a redundant pair and reside in the same chassis, the advertise

active and advertise always commands may fail to advertise routes to the associated VIP after a

failover has occurred. When the currently active CSM fails, advertised routes are correctly removed

from the route table, but these routes are not reinserted once the standby CSM becomes active. If

the active and standby CSMs reside in two different chassis, the advertise commands work properly

when a failover occurs.

• 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.

You can determine that the mask has been changed by comparing the virtual server output for the

show running command with the output from the show ip slb vserver detail command.

Workaround: Create a Cisco IOS standard IP access list, assign it to an slb policy, and assign the

policy to the virtual server.
