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)       ???

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”.
