Release Notes for Catalyst 6500 Series Content Switching Module Software Release 2.2(8)

Caveats
• CSCdy47910
In CSM release 2.2(4), when you configure the route subnet netmask gateway gateway-address
command, the gateway-address cannot be in the specified subnet netmask. You cannot configure a
route which overlaps the VLAN subnet interface.
Workaround: None
• CSCdy36736
In previous releases, after the real server failed with the inband health check option, the removal of
the inband health option would not enable the server. This problem is resolved so that when you
remove the inband health option with the no health option the CSM immediately enables the server
without waiting for the failed timer duration.
Workaround: Configuring the real server with the no in-service option and then enabling it with the
inservice command.
• CSCdy36605
In some cases the CSM permanently disables a real server after that server fails the inband health
check option. After a server fails, if the CSM sees a successful connection to the server before the
failed timer expires, the server is disabled forever.
Workaround: Configure the real server with the no in-service option, and enable it with the
inservice command.
Open Caveats in Release 2.2(4)
This section describes known limitations that exist in CSM software release 2.2(4).
• CSCdw84018
Release 2.2(x) does not support RTSP UDP streaming when a client NAT is enabled. If this
configuration is set up, the server attempts to open a UDP connection. Some RTSP clients then fall
back on interleaved mode (inline TCP). This mode will work in the application software, although
the connection is sent to fastpath.
Workaround: None
• CSCdw49073
The CSM does not support creating more than 127 virtual servers with the same virtual IP (VIP)
address, even though the CLI does allow you to configure more than 127 virtual servers. If you use
the CLI to configure more than 127 virtual servers, the 128th and subsequent virtual servers will not
function properly.
Workaround: Do not configure more than 127 virtual servers on the same VIP.
• CSCdv00464
Issuing the clear interface gigabit slot/port command for a CSM gigabit port may not clear the
counters.
Workaround: None.
• CSCdv11685
You cannot configure different fault-tolerant pairs to use the same FT VLAN.
Workaround: Use a different FT VLAN for each fault-tolerant CSM pair.
