Hi,
I have a problem with MAB: A coffeemachine is connected to a Switch with the following configuration:
interface GigabitEthernet4/0/27
switchport access vlan 6
switchport mode access
no logging event link-status
authentication control-direction in
authentication event server dead action authorize
authentication event no-response action authorize vlan 4000
authentication event server alive action reinitialize
authentication host-mode multi-auth
authentication order mab dot1x
authentication periodic
authentication timer reauthenticate server
mab
no snmp trap link-status
dot1x pae authenticator
authentication port-control Auto
storm-control broadcast level 1.00 0.50
storm-control multicast level 1.00 0.50
storm-control action trap
no cdp enable
end
the coffeemachine does not send any packet so the switch is unable to learn the MAC address and no MAB is going on. When I ping the machine from the switch the ping does not work. The switch tries to send ARP requests but does not receive any answer. When I change the port to "authentication open" everything works. The switch receives ARP answers, does MAB and the coffeemachine can answer the ping.
Is ARP not triggering a MAB?
Regards, Stefan
