Configure virual IP to monitor active WLC from HA pair via SNMP

[brych126]

I'm curious whether it is possible to configure virtual IP to be able to monitor active WLC from HA pair via SNMP. So let's assume I have HA configured for 2 WLCs: WLC1 and WLC2. I want to configure virtual IP to monitor always active WLC from this pair. So, when WLC1 goes down and my APs move to WLC2 I need to be able to automatically start to monitor WLC2 from this pair via SNMP using virtual IP. Is it possible? Thanks in advance.

yes that is the correct way of doing if you want to monitor WLC in HA.

Other hand you can also Monitor Standby WLC using Ping atleast - in case any power issue or any other mean WLC go down.

from Cisco Doc.
If the SNMP management station subnet is the same as that of the dynamic interface, we recommend that you set the SNMP queries to the IP address of the dynamic interface of the controller. Similarly, if the SNMP management station subnet is the same as that of the service port, we recommend that you set the SNMP queries to the IP address of the service port of the controller.

Controller has a limitation where, even if the queries are made to the management IP address, SNMP response packets are sent with the source IP address as the dynamic interface or the service port respectively. For more information, see CSCvk38081.

The crucial question nobody asked you: What model of WLC and what version of software?
That affects the answer and the capabilities.
