show lldp neighbors

show lldp {port [all | port_list]} neighbors {detailed}

Description

Displays the information related to the LLDP neighbors detected on the specified port or ports.

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:

# show lldp port all neighbors
Port     Neighbor Chassis ID        Neighbor Port ID           TTL     Age

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.

Platform Availability

This command is available on all platforms.
