It is not normal to see failed probes on the standby. For whatever reason the rserver is not responding to the standby probes in a successful manner or the standby is not receiving the response. Each ACE will send their own probes. You also do not need to have the same probe applied to the serverfarm and to the rservers under that serverfarm.
Re:Why do I see "FAILED" for probes on standby ACE?
On the standby ACE, if this is an ACE service module, have you made sure that on the 6500 you have assigned the VLAN being used by the servers to ACE module in the 6500 config? I've seen people forget this before.
Sorry that I made you guys busy with this question.
Fortunately, I could track down the root cause of this problem with spending a coupel of hours. I had to check all the physical ports, trunk ports, allowed vlans on trunk, and etc. After this, I checked all the configuration on the ACEs and could not find any wrong piece. so, I checked the servers and finally, I could find on the servers an access-list was configured with wrong IP addresses.
