Configuring LLDP-MED
The Cisco SPA300 Series and Cisco SPA500 Series IP phones support Link Layer
Discovery Protocol for Media Endpoint Devices (LLDP-MED) for deployment with
Cisco or other third-party network connectivity devices that use a Layer 2 auto-
discovery mechanism. Implementation of LLDP-MED is done in accordance with
IEEE 802.1AB (LLDP) Specification of May 2005, and ANSI TIA-1057 of April 2006.
Cisco SPA IP phones operate as LLDP-MED Media End Point Class III devices with
direct LLDP-MED links to Network Connectivity Devices, according to the Media
Endpoint Discovery Reference Model and Definition (ANSI TIA-1057 Section 6).
Cisco SPA IP phones support only the following limited set of TLVs as LLDP-MED
Media Endpoint device class III:
• Chassis ID TLV
• Port ID TLV
• Time to live TLV
• Port Description TLV
• System Name TLV
• System Capabilities TLV
• IEEE 802.3 MAC/PHY Configuration/Status TLV (for wired network only)
• LLDP-MED Capabilities TLV
• LLDP-MED Network Policy TLV (for application type=Voice only)
• LLDP-MED Extended Power-Via-MDI TLV (for wired network only)
• LLDP-MED Firmware Revision TLV
• End of LLDPDU TLV
The outgoing LLDPDU contains all the above TLVs when if applicable. For the
incoming LLDPDU, the LLDPDU is discarded if any of the following TLVs are
missing. All other TLVs are not validated and ignored.
• Chassis ID TLV
• Port ID TLV
• Time to live TLV
• LLDP-MED Capabilities TLV
