Parameters

interface interface-type interface-number: Specifies a port by its type and number. If you do not specify this option, the command displays the LLDP information that all ports receive from the neighboring devices.

agent: Specifies an agent type. If you do not specify an agent type, the command displays the LLDP information that all LLDP agents receive from the neighboring devices.

nearest-bridge: Specifies nearest bridge agents.

nearest-customer: Specifies nearest customer bridge agents.

nearest-nontpmr: Specifies nearest non-TPMR bridge agents.

verbose: Displays the detailed LLDP information that the local device receives from the neighboring devices. If you do not specify this keyword, the command displays the brief LLDP information that the local device receives from the neighboring devices.

list: Displays the LLDP information that the local device receives from the neighboring devices in the form of a list.

system-name system-name: Displays the LLDP information that the local device receives from a neighboring device specified by its system name. The system-name argument is a string of 1 to 255 characters. If you do not specify this option, the command displays the LLDP information that the local device receives from all neighboring devices in a list.
