We have the following Scenario,
we have 1 DHCP server, 1 AV server, and 1 client PC.
under DHCP interface we set the below.
ip arp inspection trust
ip dhcp snooping trust
under the Client PC we set the below
switchport mode access
ip arp inspection limit rate 100
under AV, nothing set.
when we push the AV agent we start getting ARP inspection errors from the agent, asking for the MAC of the AV server.
however if we trusted the AV server port for arp, problem will be solved.
can someone help me understand this behavior, why do we need to trust AV port.
