Parameters

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

agent: Specifies an agent by its type and number. If no agent type is specified, 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 this keyword is not specified, this 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 this option is not specified, this command displays the LLDP information that the local device receives from all neighboring devices in a list.
