Configures the LLDP port to advertise or not advertise port VLAN information to its neighbors.
| 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. |
| all | Specifies all VLANs on the port. |
| vlan_name | Specifies the VLAN on the port that you want to advertise. |
No advertise.
When configured to advertise, the switch inserts a port and protocol VLAN ID TLV for each VLAN configured on the ports. The port and protocol VLAN ID TLV allows the port to advertise if it supports protocol and/or tagged VLANs, along with the associated tagged values. A separate TLV is sent for each VLAN that you want to advertise.
By default, once you configure this TLV, the system sends all protocol-based VLANs on the port. However, the LLDPDU cannot exceed 1500 bytes, so you should configure the port to advertise only the specified VLANs.
Note
The total LLPDU size is 1500 bytes; any TLVs after that limit are dropped.
This TLV does not send information on the type of protocol that the VLAN has enabled; it just says whether the port is enabled or disabled for protocol-based VLANs. As Extreme Networks devices are always capable of supporting protocol-based VLANs, once you configure this TLV, the system always advertises support for these VLANs.
The following command configures all ports to advertise port and protocol VLAN information to neighbors for all VLANs on all ports:
configure lldp ports all advertise vendor-specific dot1 port-protocol-vlan-id
This command was first available in ExtremeXOS 11.2.
This command is available on ExtremeSwitching X435, X440-G2, X450-G2, X460-G2, X465, X590, X620, X690, and X695 series switches.
