configure lldp ports vendor-specific dot1 port-vlan-ID

configure lldp ports [all | port_list] [advertise | no-advertise] vendor-specific dot1 port-vlan-ID


Configures the LLDP (Link Layer Discovery Protocol) port to advertise or not advertise port vlan ID information to its neighbors. This allows a VLAN (Virtual LAN) bridge port to advertise the port VLAN identifier that is associated with untagged or priority-tagged frames.

Syntax Description

all Specifies all ports on the switch.
port_list Specifies one or more ports or slots and ports.
advertise Specifies to send the information to neighbors.
no-advertise Specifies not to send the information to neighbors.


No advertise.

Usage Guidelines

The port VLAN ID TLV allows the port to transmit the VLAN ID associated with untagged VLANs. There can be only one port VLAN ID in each LLPDU.

If no untagged VLANs are configured on the specified port, the TLV is not added to the LLPDU, even if you configured this to advertise.


The following command configures all ports to advertise port vlan ID information to neighbors:

configure lldp ports all advertise vendor-specific dot1 port-vlan-ID


This command was first available in ExtremeXOS 11.2.
