I have had a customer raise an issue with me. Unfortunately I am not too hot on the CSM.
Switch Type - Cisco WS-C6513
IOS VSN - 12.2(18)SXF4
CSM Module details
Card Type - SLB Application Processor Module
Model - WS-X6066-SLB-APC
Hardware VSN - 1.8
Software VSN - 4.2(5)
I have spotted bug CSCsc38892, but cannot tell if the catakyst is running VRF - this is all the info I have been given.
We have 6500 chassis each with a CSM module in fault tolerance (ft) mode.
The current standby module (at the time it was the active one) reports as per output below that probes failed:
sh mod csm 1 real sf SAPCCP
real server farm weight state conns/hits
-------------------------------------------------------------------------
10.xxx.xxx.xxx:8000 SAPCCP 8 PROBE_FAILED 0
10.xxx.xxx.xxx:8000 SAPCCP 8 PROBE_FAILED 0
10.xxx.xxx.xxx:8000 SAPCCP 8 PROBE_FAILED 0
Probe failed could be for a number of reasons however the inconsistency is that the failed probes follow the CSM module and that the other module has working probes.
It is to be noted that the command “ping module csm 1 10.xxx.xxx.xxx†reports to be reachable as a good indicator that there is connectivity from the CSM to the server.
The following is the output from the currently active CSM (which used to be the standby one):
sh mod csm 1 real sf SAPCCP
real server farm weight state conns/hits
-------------------------------------------------------------------------
10.xxx.xxx.xxx:8000 SAPCCP 8 OPERATIONAL 51
10.xxx.xxx.xxx:8000 SAPCCP 8 OPERATIONAL 41
10.xxx.xxx.xxx:8000 SAPCCP 8 OPERATIONAL 52
