Arp inspection

Unanswered Question
Jun 17th, 2008

I enable arp inspection and have a acl for mapping IP to MAC and apply it to VLAN 200.

What happen if a packet with IP is not in the ACL is received on VLAN 200 ? Does the switch flood it or drop it ?

The switch is 4500.

I have this problem too.

on the awitch, enter the following global configuration command:

"ip arp inspection vlan " where the vlan number you are using

- clear the arp table on the host

Once doing this you will notice that "show ip arp insoection vlan " is enabled/active.

It will drop it, you will get no connectivity until you create the appropriate binding.
