Setting Port Link Traps and Link Flap Detection

Purpose

To disable or re‐enable link traps, display link trap status, and to configure the link flapping
detection function. By default, all ports are enabled to send SNMP trap messages indicating
changes to their link status (up or down).
The link flap function detects when a link is going up and down rapidly (also called "link
flapping") on a physical port, and takes the required actions (disable port, and eventually send
notification trap) to stop such a condition. If left unresolved, the "link flapping" condition can be
detrimental to network stability because it can trigger Spanning Tree and routing table
recalculation.
