Hi
Log from one of the switches in our Intranet.
un 20 13:08:29.667 CEST: %SW_DAI-4-DHCP_SNOOPING_DENY: 1 Invalid ARPs (Req) on Fa0/14, vlan 266.([0013.21f4.27de/10.101.7.34/0000.0000.0000/10.101.7.1/13:08:28 CEST Wed Jun 20 2012])
IP adress on host connected to Fa0/14 : 10.101.7.34
Default gateway : 10.101.7.1
The reason is maybe something wrong with the ARP table or the DHCP snooping bindings, maybe a man in the middle attack.
Need to know the location of the host that was the reason is located. From another host in the the network, or the host on Fa 0/14 ?
Req means request so maybe something was wrong with the MAC to IP bindings for the host on Fa0/14 ?
Thank you,
Best regards,
Oyvind
