Syntax Description

all	Specifies all ports on the switch.
port_list	Specifies one or more ports or slots and ports.
detailed	Shows detailed information on the neighbors.

Default

N/A.

Usage Guidelines

You must use the detailed parameter to display detailed information about the received LLDP TLVs.

Example

The following example displays LLDP neighbor information for all switch ports:

History

This command was first available in ExtremeXOS 11.2. Information on the LLDP MED extension and Avaya-Extreme proprietary TLVs was added in ExtremeXOS 11.5.

Additional PoE+ information can appear when present in a Power via MDI TLV received from a neighbor starting in ExtremeXOS 12.5.

"System Name" was added to the ouput in ExtremeXOS 22.1.

Management IP address information was added in ExtremeXOS 22.4.

Port Extension TLV information for bridge port extenders (BPEs) was added in ExtremeXOS 22.5.
