Can 460 series switches send VLAN information using LLDP TLVs to the end devices?

[Juan_Sevillano]

We are trying to display Vlan information when troubleshooting a port using Netscout LinkRunner AT 2000, Here is the configuration on the port we are testing, we are able to get the switch port and IP, but not the Vlan.

configure lldp port 2:6 advertise vendor-specific dot1 port-vlan-id
configure lldp port 2:6 advertise vendor-specific dot1 port-protocol-vlan-id
configure lldp port 2:6 advertise vendor-specific med capabilities
configure lldp port 2:6 advertise vendor-specific med power-via-mdi

configure lldp port 2:6 advertise vendor-specific dot1 vlan-name vlan Voice
configure lldp port 2:6 advertise vendor-specific med policy application voice vlan Voice dscp 4

Hello,

You can find a list of all of the EXOS supported LLDP TLVs in the EXOS User Guide (Starting on p.368 and p.377).

https://documentation.extremenetworks.com/exos_16.2/downloads/GUID-D7F66DD0-BFE9-4227-8A38-D965ABE5C...

It looks like you’ve found the relevant advertisements that include VLAN information. The next step is identifying which advertisements the LinkRunner will accept. Sometimes, having too many advertisements can overwhelm the end-system, so you may need to remove any that are not absolutely necessary.

You may be able to get the same info with CDP or EDP as well; although I suspect the LinkRunner does not support EDP (Extreme’s version of CDP). You can check with the following commands on EXOS:

[enable | disable] cdp ports <ports>

show cdp neighbor detail

[enable | disable] edp ports <ports>

show edp port all detail

Hope that helps,

Gabriel
