12.2(35)SE-MAB

i am using cisco 3750 switch with radius configured on it. Al works fine for dot1x authentication. The come appears when ip phone is in the picture. phones stop working when dot1x is configured on port and they dont come up until user is autheticated from pc. We have nortel ip phone. i am using latest release of switch 12.2(35)SE specially as it has MAB feature and i was expecting that after i enable this feature my phones will work even if i dont have a pc authenticated to that port.

please see below as i am using 1/0/45 for my dot1x port with phone attached to it and 1/0/47 is a trunk port.

conf of dot1x port as as below:

Switch#show running-config interface fastEthernet 1/0/45

Building configuration...

Current configuration : 200 bytes

!

interface FastEthernet1/0/45

switchport mode access

switchport voice vlan 6

dot1x mac-auth-bypass

dot1x pae authenticator

dot1x host-mode multi-host

spanning-tree portfast

end

Debug report for dot1x all in attached file

You need to tell the port to trust the dcsp values from your ip phone
