## Disable LLDP Basic Optional TLVs

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

   See Configure the LLDP Module Status.

2. At both switches, configure VLAN name as `vlan 1`.

       SEFOS# configure terminal
       SEFOS(config)# vlan 1
       SEFOS(config-vlan)# ports extreme-ethernet 0/1 name vlan 1
       SEFOS(config-vlan)# end

3. At both switches, enable all of the TLVs by executing the instructions in the following sections.

   - See Enable LLDP Optional TLVs.

   - See Enable IEEE 802.1 Organizationally-Specific TLVs.

   - See Enable IEEE 802.3 Organizationally-Specific TLVs.

4. At both switches, disable the basic optional TLVs.

       SEFOS# configure terminal
       SEFOS(config)# interface extreme-ethernet 0/1
       SEFOS(config-if)# no lldp tlv-select basic-tlv port-descr sys-name sys-descr sys-capab mgmt-addr all
       SEFOS(config)# end

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

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

   The enabled TLVs do not display any basic optional TLVs because basic they are disabled.

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

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