SNMP Discovery of clients through WLC problems

[tahequivoice]

I have a client with a 2112 WLC and 1252AG radios. The clients work fine, but an SNMP management server can not reach any of the clients over the wireless. Before the WLC and new AP's were installed, they were running older Cisco Autonomous AP's and had no problems with SNMP.  My monitoring system uses SNMP and it can reach the WLC just fine, so there doesnt appear to be any issues on the switched network.

What can be blocking the SNMP on the WLC?

You have the snmp network defined on the wlc?

In what way?  The network the server is on also has a WLAN interface on the WLC. In fact the network the clients use is the same one they used before on the autonomous AP's, only difference is there is the WLC in between now.

In the snmp configuration there is an area to define the network to allow. Usually the snmp is for WCS to communicate with the wlc.

the WLC, by default doesn't communicate when you bridge the VLANs. Do the clients need to be in the same subnet as the SNMP server? If not, remove the interface and they should be able to communicate.

If they do need to hVe in that subnet, then you need to enable management via dynamic interface
