On the site (or foreign) WLC, I am receiving the following message in its message logs:

*mmListen: Nov 03 22:46:36.954: #MM-3-PING_RESPONSE_DROPPED: mm_ping.c:378 Drop mobility ping reply from 137.183.242.149. Expected reply from 0.0.0.0. bogus reply.
*mmListen: Nov 03 22:46:36.951: #MM-3-PING_RESPONSE_DROPPED: mm_ping.c:378 Drop mobility ping reply from 137.183.242.150. Expected reply from 0.0.0.0. bogus reply.

 

137.183.242.149 and .150 are the anchor WLCs.

 

The mobility peers on the site WLC are UP...

I don't see drops on the anchor WLCs. Pings from the site WLC to the anchors seem solid (don't drop).

Where else should I look?
