Hi All,
we need to monitor access ports with 802.1x enabled on them via regular SPAN. we are using 3750x and Cat6k.
When dot1x authentication failed on 3750 and port state is in "up/down", we can still see broadcast packets (arp request) on the monitor station
When dot1x authentication failed on 6500 and port is in "up/down" , we don't see any packet on the monitor station.
we are using the same configuration on both switches:
aaa new-model
aaa authentication dot1x default group radius
dot1x system-auth-control
dot1x critical eapol
radius-server host x.x.x.x auth-por 1812 acc-port 1813 key XXXXXXXX
int gi x/x
authentication port-control auto
authentication periodic
dot1x pae authenticator
please advise,
Avi
