I could see both MAB & Dot 1x authenticates thru' Radius server.  Raduis server has the MAC directories and it assigns a appropriate VLAN for the respective MAC.  According to me, the difference is only with protocols they use.  In our environment we use mab as a fallback for dot1x. What i want to know is ? 1. Why have we moved from MAB to dot1x. 2. How is dot1x better than MAB. 3. Can cisco phones authenticate with dot1x. It usually authenticates only with MAB. 4. What does dot1x do differently in raduis server that MAB does not.  5. Can cisco phone allow a computer connected to it to authenticate with dot1x with phone authenticates only with MAB assuming we have new model cisco phones which supports dot1x. 6. With the below configuration, will the phone connected to this port authenticate with dot1x. The reason why i m asking this, phone is already assigned with correct vlan in the switch config itself. 7. In new model cisco phones, we have option to disable/enable dot1x. what does this actually do? Why is this option for. please find the same config on the switch port.  switchport access vlan 1 switchport mode access switchport voice vlan 4 srr-queue bandwidth share 4 4 60 20 srr-queue bandwidth shape 4 0 0 0 authentication event fail action authorize vlan 99 authentication event no-response action authorize vlan 99 authentication event server alive action reinitialize authentication host-mode multi-domain authentication order dot1x mab authentication priority dot1x mab authentication port-control auto authentication periodic authentication timer reauthenticate server mab mls qos trust device cisco-phone mls qos trust cos dot1x pae authenticator dot1x timeout tx-period 1 spanning-tree portfast service-policy input qp_store_in ...

I found the below dial-peer recently added to the gateway with the help of monitoring tool and the time when i removed the dial-peer the gateway registered with GK.  Dial-peer voice 1111 ports Destination-pattern 96xxxxxxxxxx ports 0/1/3   When I configure the dial-peer in lab router and found the number mentioned in the destination pattern is registering with GK and its not allowing the gateway to GK with h323 ID and also getting duplicate alias entry in h225 asn debug. But my questions are   Why the number configured in Dial-peer destination pattern is registering with GK?

Why only the dial-peer 1111 was affecting the gateway registration to GK? ... View more
