With CDP compatibility enabled, your device can receive and recognize CDP packets from a Cisco IP phone and respond with CDP packets, which carry the voice VLAN configuration TLVs. The voice traffic is confined in the configured voice VLAN, and differentiated from other types of traffic.

CDP-compatible LLDP operates in one of the following modes:

TxRx: CDP packets can be transmitted and received.

Disable: CDP packets cannot be transmitted or received.
