ACE keep probing real servers using "https get 302"

[Charles_Chi4]

Hi all,

I got one problem with cisco ACE in my company. Currently, two ACE appliances are working as HA redundancy. Previously I enabled some https and http probing using get 302 for some servers and services. But then I was told to remove all https or http probing, and instead use tcp port 443 and 80. After that, one of the serverfarm (server groups) is receiving https get 302 and I already checked in the monitoring and see whether there's any https probing regarding the respected real servers. But I could not find any. Even I disable all probing to that serverfarm, all the server members still receiving https get 302. Is this behavior a bug?

The ACE version is A3(2.1). And the HA status is on standby cold. Can standby cold cause this kind of trouble?

Hi Charles,

When an ACE is in STANDBY-COLD state, configurations may not be properly synchronized, so,it's possible that the probe configuration is still present on the standby device.

Also, I would suggest you to check what is the source IP for the probe connections. An ACE will use the real interface IP to open probe connections, so, this should give you a good idea of which device is generating the connections.
