Caveats

• CSCdt77071

When a cookie sticky or SSL sticky group is created and then associated with a virtual server, the

virtual server changes its type to IP sticky.

Workaround: Create a policy, associate the sticky group with it, and then associate the policy with

the virtual server.

• CSCdt78663

When using RHI (Route Health Injection) in a fault-tolerant configuration, traffic from a VIP may

go into a routing loop because the standby CSM replies to the VIP ARP request before the active

CSM replies. This problem occurs when ip proxy-arp, which is enabled by default, is not disabled.

Workaround: Disable ip proxy-arp on the MSFC VLAN interfaces that reside on the CSM client

VLANs using the no ip proxy-arp command.

• CSCdt78707

When a VIP is configured and falls outside the address range of existing client VLANs, it will appear

as operational when status is displayed using the show ip slb virtual-server detail command.

Workaround: Ignore this message.

• CSCdv78416

When using the no ip slb map command (or no map in the module CSM submode) in IOS 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,orno 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.

• 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.

• 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.
