show lldp

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

Description

Displays LLDP (Link Layer Discovery Protocol) configuration information for the specified port or ports.

Use the detailed keyword to display the configured VLAN (Virtual LAN)s on the port and the enabled VLAN-specific TLVs.

Syntax Description

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

Default

N/A.

Usage Guidelines

Use the detailed variable to display information regarding configured VLANs on the ports and any enabled VLAN-specific TLVs.

Example

The following example displays LLDP configuration information for the switch:

# show lldp
LLDP transmit interval           : 30 seconds
LLDP transmit hold multiplier    : 4  (used TTL = 120 seconds)
LLDP transmit delay              : 2 seconds
LLDP SNMP notification interval  : 5 seconds
LLDP reinitialize delay          : 2 seconds
LLDP-MED fast start repeat count : 4

History

This command was first available in ExtremeXOS 11.2.

The information on fast-start repeat count, MED, AvEx, and notification was added in ExtremeXOS 11.5.

An additional flag was added for PoE+ in ExtremeXOS 12.5.

The display was updated for DCBX in ExtremeXOS 12.6.
