Configuring for Network Management Applications

LLDP (Link-Layer Discovery Protocol)

LLDP-MED Topology Change Notification

This optional feature provides information an SNMP application can use to

track LLDP-MED connects and disconnects.

Syntax: lldp top-change-notify < port-list >

Topology change notification, when enabled on an LLDP port,

causes the switch to send an SNMP trap if it detects LLDP-

MED endpoint connection or disconnection activity on the

port, or an age-out of the LLDP-MED neighbor on the port. The

trap includes the following information:

■ the port number (internal) on which the activity was

detected (For more in internal port numbers, refer to

“Determining the 5300xl Port Number Included in

Topology Change Notification Traps” on page 15-71.)

■ the LLDP-MED class of the device detected on the port

(“LLDP-MED Endpoint Device Classes” on page 15-49.)

The show running command shows whether the topology

change notification feature is enabled or disabled. For

example, if ports A1-A10 have topology change notification

enabled, the following entry appears in the show running

output:

lldp top-change-notify A1-A10

(Default: Disabled)

Note: To send traps, this feature requires access to at least

one SNMP server. For information on configuring traps, go to

the chapter titled “Configuring for Network Management

Applications” in the Management and Configuration Guide for

your switch, and refer to one of the following sections:

• SNMPv1 and SNMPv2c Trap Features

• SNMPv3 Notification and Traps

Also, if a detected LLDP-MED neighbor begins sending

advertisements without LLDP-MED TLVs, the switch

sends a top-change-notify trap.
