Caveats
Open Caveats in Release 2.2(3)
This section describes known limitations that exist in CSM software release 2.2(3).
• 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.
• 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.
• 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 CSM software release 2.x, 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:
