Configure Cisco Discovery Protocol (CDP)

CDP is negotiation-based and determines which VLAN the IP phone resides in. If you are using a Cisco
switch, Cisco discovery protocol (CDP) is available and is enabled by default. CDP:

•
If you are using a VLAN without CDP, you must enter a VLAN ID for the IP conference phone.

Configure LLDP-MED

The IP conference phones support Link Layer Discovery Protocol for Media Endpoint Devices
(LLDP-MED) for deployment with Cisco or other third-party network connectivity devices that use a
Layer 2 auto-discovery mechanism. Implementation of LLDP-MED is done in accordance with IEEE
802.1AB (LLDP) Specification of May 2005, and ANSI TIA-1057 of April 2006.
The IP conference phone operates as LLDP-MED Media End Point Class III devices with direct
LLDP-MED links to Network Connectivity Devices, according to the Media Endpoint Discovery
Reference Model and Definition (ANSI TIA-1057 Section 6).
The IP conference phone supports only the following limited set of TLVs as LLDP-MED Media
Endpoint device class III:

The outgoing LLDPDU contains all the above TLVs when if applicable. For the incoming LLDPDU, the
LLDPDU is discarded if any of the following TLVs are missing. All other TLVs are not validated and
ignored.
