Caveats

Open Caveats in Software Release 2.1(2)

This section describes known limitations that exist in CSM software release 2.1(2).

• CSCdu57891

The output from the show interface gigabit slot/port command may erroneously indicate that one

or more of the CSM gigabit ports are down.

Workaround: Ignore the display.

• CSCdu82478

In the Content Switching Module (CSM) software release 2.1.1, it is important that packets

transmitted from the CSM toward a client (server) are transmitted on the same VLAN as packets

received by the CSM from that same client (server). This constraint may be satisfied as follows:

–

Ensure that all routes to any particular destination go through the same VLAN. Multiple routes

on the CSM to the same destination are supported, but all such routes need to go through

gateways on the same VLAN. For example, the following configuration is invalid because it is

possible for traffic from a remote source to arrive on both VLAN 10 and VLAN 20:

Router(config)# module csm 4

Router(config-module-csm)# vlan 10 client

Router(config-slb-vlan-client)# gateway 1.1.1.1

Router(config-module-csm)# vlan 20 client

Router(config-slb-vlan-client)# gateway 2.2.2.2

To make this a valid configuration, delete the gateway command from either VLAN 10 or

VLAN 20.

Note NOTE: Do not use the gateway command in more than one VLAN

–

Ensure that all traffic received by the CSM from a specific destination address arrives on the

same VLAN as the route the CSM uses to reach that destination. If the CSM is configured with

a route as follows, for load balancing to function properly, all traffic arriving from the

10.0.0.0/24 subnet must reach the CSM through VLAN 10.

Router(config)# module csm 4

Router(config-module-csm)# vlan 10 client

Router(config-slb-vlan-client)# route 10.0.0.0 255.255.255.0 gateway 1.1.1.1

• .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.
