Advertising TLVs
You can congure the system to advertise TLVs out of all interfaces or out of specic interfaces.
• If you congure the system globally, all interfaces send LLDPDUs with the specied TLVs.
• If you congure an interface, only the interface sends LLDPDUs with the specied TLVs.
• If you congure LLDP both globally and at interface level, the interface level conguration overrides the global conguration.
To advertise TLVs, use the following commands.
1 Enter LLDP mode.
CONFIGURATION or INTERFACE mode
protocol lldp
2 Advertise one or more TLVs.
PROTOCOL LLDP mode
advertise {management-tlv | dot1-tlv | dot3-tlv | med}
Include the keyword for each TLV you want to advertise.
• For management TLVs: system-capabilities, system-description.
• For 802.1 TLVs: port-protocol-vlan-id, port-vlan-id.
• For 802.3 TLVs: max-frame-size.
• For TIA-1057 TLVs:
– guest-voice
– guest-voice-signaling
– location-identification
– power-via-mdi
– softphone-voice
– streaming-video
– video-conferencing
– video-signaling
– voice
– voice-signaling
In the following example, LLDP is enabled globally. R1 and R2 are transmitting periodic LLDPDUs that contain management, 802.1, and
802.3 TLVs.
