hi , i'm installing ipphone on 3560 with 802.1x authentication and host mode multi-domain ,all works fine for ipphone but PC behind ipphone can't
receive an ip address via dhcp although dot1x guest vlan data is configured, is supplicant and 802.1x authentication mandatory on pc as on ipphone or can i have only authentication on ipphone and none on PC ?
is there some issue known for that situation ?
how long is a mac addres locked if dot1x authen failed ? is that timer configurable ? is the mac address locked for the port or for all switch port ?
