Please Note: The preferred method to assign VLANs to Nortel IP Phones is LLDP if available.
The Network policy TLV allows both network connectivity devices and endpoints to advertise
VLAN configurations and associated Layer 2 and Layer 3 attributes for the specific application on
that port. The switch can notify a phone of the VLAN number that it should use. The phone can
connect into any switch, obtain its VLAN number, and then start communicating.
By default all LLDP TLVs are enabled.
You can enable the TLVs globally or at an interface level.
