Disable IEEE 802.1 Organizationally-Specific 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 IEEE 802.1 organizationally-specific TLVs.

   SEFOS# configure terminal
   SEFOS(config)# interface extreme-ethernet 0/1
   SEFOS(config-if)# no lldp tlv-select dot1tlv port-vlan-id protocol-vlan-id all vlan-name all
   SEFOS(config)# end

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

   SEFOS# show lldp local extreme-ethernet 0/1

   Enabled Tx TLVs do not display any IEEE 802.1 organizationally-specific TLVs. In addition, PPVIDs and VLAN name TLVs are disabled because IEEE 802.1 organizationally-specific TLVs are disabled.

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