Configuring for Network Management Applications

LLDP (Link-Layer Discovery Protocol)

■Class 3 (Communication Devices): These devices are typically IP phones or end-user devices that otherwise support IP media and offer all Class 1 and Class 2 features, plus location identification and emergency 911 capability, Layer 2 switch support, and device infor­ mation management.

LLDP-MED Operational Support. The switches covered in this guide offer two configurable TLVs supporting MED-specific capabilities:

■medTlvEnable (for per-port enabling or disabling of LLDP-MED opera­ tion)

■medPortLocation (for configuring per-port location or emergency call data)

N o t e

LLDP-MED operation also requires the port speed and duplex TLV

 

(dot3TlvEnable; page 13-53), which is enabled in the default configuration.

 

 

LLDP-MED Topology Change Notification

This optional feature provides information an SNMP application can use to track LLDP-MED connects and disconnects.
