Configures the LLDP (Link Layer Discovery Protocol) port to advertise or not advertise VLAN (Virtual LAN) name information to its neighbors. Use this TLV to advertise information for the tagged VLANs you want to specify on the port. This allows an IEEE 802.1Q-compatible 802 LAN station to advertise the assigned name of any VLAN with which it is configured.
| 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. |
| vlan | Specifies all VLANs on the port. |
| vlan_name | Specifies the VLAN on the port that you want to advertise. |
No advertise.
The VLAN name TLV sends the VLAN name and the tag used; it associates a name to a tag for the specified VLAN. This allows an IEEE 802.1Q-compatible 802 LAN station to advertise the assigned name of any VLAN with which it is configured.
You can enable this TLV for tagged and untagged VLANs. When you enable this TLV for tagged VLANs, the TLV advertises the IEEE 802.1Q tag for that VLAN. (For untagged VLANs, the internal tag is advertised.) You can specify exactly which VLANs to advertise.
When configured to advertise, the switch inserts a VLAN name TLV for every VLAN configured on the ports. By default, once you configure this TLV, the system sends all VLAN names on the port. However, each VLAN name can require up to 32 bytes and the LLDPDU cannot exceed 1500 bytes, so you should configure the port to advertise only the specified VLANs, using the keyword vlan_name.
Note
The total LLPDU size is 1500 bytes; any TLVs after that limit are dropped.
The following command configures all ports to not advertise VLAN name information to neighbors:
configure lldp ports all no-advertise vendor-specific dot1 vlan-name
This command was first available in ExtremeXOS 11.2.
This command is available on the Summit X450-G2, X460-G2, X670-G2, X770, and ExtremeSwitching X440-G2, X620, X690, X870 series switches.
