CSM Probe Status of ???

I must be bored since I’m posting again.

A colleague asked me to change the failed value of a TCP probe today.  It was no big deal, but, when I looked to see the status of the change, I noticed interesting stati of the RIPs.

switch#sh mod csm 7 probe name TCP80-PROBE detail probe           type    port  interval retries failed  open   receive --------------------------------------------------------------------- TCP80-PROBE  tcp     80    20       3       120     10 Description: Quick fail recovery recover = 3 real                  vserver         serverfarm      policy          status ------------------------------------------------------------------------------ 192.168.1.45:80       VS01            FARM01        (default)       ??? 192.168.1.44:80       VS01            FARM01        (default)       ??? 192.168.1.43:80       VS01            FARM01        (default)       ??? 192.168.1.42:80       VS01            FARM01        (default)       ???

1 2 3 4 5 6 7 8 9 10 11 12

switch#sh mod csm 7 probe name TCP80-PROBE detail probe           type    port  interval retries failed  open   receive --------------------------------------------------------------------- TCP80-PROBE  tcp     80    20       3       120     10 Description: Quick fail recovery recover = 3 real                  vserver         serverfarm      policy          status ------------------------------------------------------------------------------ 192.168.1.45:80       VS01            FARM01        (default)       ??? 192.168.1.44:80       VS01            FARM01        (default)       ??? 192.168.1.43:80       VS01            FARM01        (default)       ??? 192.168.1.42:80       VS01            FARM01        (default)       ???

It seems that when a change is made to a probe, the CSM discards the state of the probe and starts over.  If you catch it before the first probe is finished, you’ll get a status of “???”.  I’m just picturing the CSM saying “Uhh…I…don’t…know”.

It quickly cleared back to “OPERABLE”, and my morning fun was gone. 🙁
