Figure 12-6. Viewing LLDP Activity on Router Interfaces
The show lldp interface command displays the number of LLDP messages
all interfaces on the local router have received (input packets) and transmitted
(output packets). For the received LLDP, the command line interface (CLI)
also displays the number of TLVs that had errors and that have been discarded.
When a neighbor does not send an update after the TTL for a previous message
has expired, the neighbor ages out. The router assumes that endpoint no
longer exists. The number of aged-out neighbors is also displayed.
You can also limit the information to a specific interface. For example:
ProCurve# show lldp interface eth 0/1
If you want to see a summary of how many neighbors the router has added
and deleted, enter:
ProCurve# show lldp neighbors statistics

Viewing Real-Time LLDP Messages: debug lldp Commands

If your network is experiencing unexplained congestion, you can use the
debug commands to explore whether a faulty interface is flooding the net-
work with LLDP messages. You can also use the debug lldp commands to
determine which interfaces are sending and receiving LLDP messages and
what information these messages contain.
Debug messages are processor intensive.
