Avaya–Extreme Networks Optional TLVs

The software supports a set of TLVs that are proprietary to Avaya and Extreme Networks.

These TLVs advertise and receive information for Avaya voice over IP (VoIP) telephones, which include powered device (PD) information. Some TLVs are advertised by the switch, and some are advertised by the telephone. The switch starts advertising these proprietary TLVs when you enable LLDP (Link Layer Discovery Protocol) and configure the specified TLVs to be advertised. The switch receives the proprietary TLVs when LLDP is enabled; you do not have to configure the switch to receive individual TLVs.
