• If you configure an interface, only the interface will send LLDPDUs with the specified TLVs.
If LLDP is configured both globally and at interface level, the interface level configuration overrides the
global configuration. To advertise TLVs:
Step Task
1 Enter LLDP mode.
2 Advertise one or more TLVs. Include the keyword for
each TLV you want to advertise.
• For management TLVs:
system-description
• For 802.1 TLVs:
port-vlan-id, vlan-name
• For 802.3 TLVs:
• For TIA-1057 TLVs:
•guest-voice

•
•location-identification
•power-via-mdi
•softphone-voice
•streaming-video
•video-conferencing
•video-signaling
•voice
•voice-signaling
