Experiencing a very frustrating issue with our current RAP architecture. The DHCP scope that serves users behind our RAPs gets flooded with BAD_ADDRESS entries. This causes all addresses to become available and users are unable to get on the network. We have 25-30 scopes in our environment and this is the only scope that it's happing on. Architecture looks like this:
7210 HeadEnd ===INTERNET===RAP-155/RAP-3 === Small Switch
The SSID and the wired connections in the switch are all on the same VLAN/network. The default gateway handed out to all clients on that network is our core routers, not the controller. Not sure if that matters.
Anyone come across a similar situation? We've sniffed the DHCP server VLAN and there is no smoking gun, yet the scope continues to fill up.
I have a TAC case open, however I thought I'd throw it out here as well. Thanks!
