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.
123456789101112 switch#sh mod csm 7 probe name TCP80-PROBE detailprobe type port interval retries failed open receive---------------------------------------------------------------------TCP80-PROBE tcp 80 20 3 120 10Description: Quick fail recoveryrecover = 3real 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. 🙁
