H3C, Avaya VOIP and 802.1x

When I connect an Avaya 9600 phone to a H3C 802.1x port, the phone just works, it doesn't need or attempt any sort of authentication. I do not have to have a pc connected in line with the phone.  I like this behavior, but I don't understand it.  I have the voice vlan oui's set statically, so it's operating in secure mode.  Could someone explain why 802.1x on the port bypasses for the phone?

Most likely the switch has auto assigning voice vlan into which it places devices matching the MAC address vendor portion, first 48bits
Or based on datastream.....

Check the spec of the switch to confirm.

most probably the switch is configured with LLDP with ADAC, assuming you are using Nortel or Avaya  base switch

Because i remember i configured LLDP and ADAC and it made my life much much easier and i had to do is plugged my phone into the LAN and boom the phone will automatically will take voice vlan ip address PBX IP and the workstation will be assigned to appropriate vlan ip address

You were not asking for a solution, you were looking for info on how the setup works.
