Enable LLDP Optional TLVs

This section describes how to configure basic optional TLVs for transmission when the transmission status is set to Disabled by default. The following optional TLVs are in LLDP:

• Port description

• System name

• System description

• System capabilities

To enable the LLDP optional TLVs, perform the following steps:

1. At both switches, enable basic optional TLVs.

   SEFOS# configure terminal
   SEFOS(config)# interface extreme-ethernet 0/1
   SEFOS(config-if)# lldp tlv-select basic-tlv port-descr sys-name-sys-descr sys-capab mgmt-addr all
   SEFOS(config)# end

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

   SEFOS# show lldp local extreme-ethernet 0/1
   Port Id SubType            : Interface Alias
   Port Id                : Slot0/1
   Port Description            : Ethernet Interface
   Enabled Tx Tlvs            : Port Description, System Name, 
                       System Description, System Capability,                             Management Address
   ...

3. Review the local management address.

   SEFOS# show lldp local mgmt-addr
   Management Address            TxEnabledPorts
   ------------------            --------------
   12.0.0.1                Ex0/1

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

   SEFOS# show lldp neighbors ex 0/1 detail
