I have configured a wireless LAN controller and am having issues with clients obtaining an IP address via DHCP.
The access points (1131AG) pickup an IP address from the DHCP server without a problem, the clients connect to the wireless network ok, but fail to get and IP address assigned, the error on the wireless controller is as follows
"Jul 02 10:01:17.036 dtl_net.c:1191 DTL-1-ARP_POISON_DETECTED: STA [00:19:d2:b2:0d:fa, 0.0.0.0] ARP (op 1) received with invalid SPA 172.17.7.4/TPA 172.17.7.1"
Can some one tell me anything about this error ?
Any help would be greatly appreciated
