Enable IEEE 802.3 Organizationally-Specific TLVs

This section describes how to configure IEEE 802.3 organizationally-specific TLVs for transmission when the transmission status is set to disabled by default. The following basic optional TLVs are in LLDP:

• Medium access control layer and the physical layer configuration and status

• Link aggregation

• Max frame size

1. At both switches, configure the LLDP module status as enabled.

   See Configure the LLDP Module Status.

2. Enable the IEEE 802.3 organizationally-specific TLVs on the extreme-ethernet 0/1 interface.

   SEFOS# configure terminal
   SEFOS(config)# interface extreme-ethernet 0/1
   SEFOS(config-if)# lldp tlv-select dot3tlv macphy-config link-aggregation max-framesize 
   SEFOS(config)# end

3. At switch 1, review the local system information.

   SEFOS# show lldp local extreme-ethernet 0/1
   ...
   Enabled Tx Tlvs            : Mac Phy, Link Aggregation, Max Frame Size
   ...

4. At switch 2, review the information about the learned neighbors on the interface.

   SEFOS# show lldp neighbors extreme-ethernet 0/1 detail
   ...
