11.4 Layer 2 Discovery Protocols
This feature detects Layer 2 Discovery Protocol messages
broadcast by Layer 2 devices over the network to inform
each other of their existence and capabilities. The
ValidatorPRO-NT supports Cisco Discovery Protocol (CDP)
and Link Layer Discovery Protocol (LLDP)
To view Layer 2 (L2) Discovery Protocol broadcast
messages select Network Tests from the Start menu then
select L2 Discovery Protocols from the Network Tests menu.
Next connect a patch cable from the ValidatorPRO-NT, Cu
main unit’s network port to the Ethernet interface to be
monitored for L2 discovery protocols.
L2 discovery protocol information automatically displays and
a message “Reading L2 Discovery Packets from Network”
appears on the screen.
