[ERROR] dhcp_proxy.c 2897 on Wireless LAN controllers

[SHANNON WYATT]

I get the following errors on all of the Wireless LAN controllers I have configured:

Thu Oct 27 14:08:41 2005 [ERROR] dhcp_proxy.c 2897: Received a packet from ourselves, network loop!

Thu Oct 27 14:08:26 2005 [ERROR] dhcp_support.c 357: dhcp_bind(): servPort dhcpstate failed

Thu Oct 27 14:08:26 2005 Previous message occurred 226 times

The network is configured as such:

Controllers are connected to trunk port on a 3750 Switch with all of the VLANs configured. Helper addresses are on most of the VLAN interfaces. I assume that I get that error because the VLAN interface is answering the DHCP request as well as the DHCP proxy in the controller. Is that the issue?

This is a known issue. To resolve this issue Configure a bogus IP address on the service port and disable DHCP. Make sure the IP address is a completely different network than the manager or ap-manager interfaces. Hope this helps.
