Recently upgraded a remote 1231-AG AP to run in LWAPP mode. The controller talks to the AP; AP's running in Local mode since it doesn't support REAP or HREAP. Remote clients are not getting IP addresses.
It's my understanding... since the AP is running in Local mode, the DHCP server must reside where the WLC is located. I enabled DHCP server on the WLC.
When I had a remote client try authenticating, I see the following in the message logs:
Jun 21 11:00:29.746 dtl_net.c:1191 DTL-1-ARP_POISON_DETECTED: STA [00:13:ce:e3:40:6c, 0.0.0.0] ARP (op 1) received with invalid SPA 169.254.208.65/TPA 169.254.208.65
Anyone see this error before?
