White Paper Abstract:
This paper compares LLDP-MED and the Cisco Discovery Protocol specifically as they relate to phones and switches. It also identifies some outstanding concerns that affect both development and deployment of multiple discovery protocols.
Cisco plans to initially support LLDP and LLDP-MED on both IP phones and LAN switches to provide multi-vendor interoperability. Because Cisco Discovery Protocol is widely deployed and provides some additional capabilities beyond LLDP-MED, Cisco will continue to fully support Cisco Discovery Protocol along with LLDP and LLDP-MED.
