show lldp

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

Description

Displays LLDP configuration information for the specified port or ports.

Use the detailed keyword to display the configured VLANs 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
