In a WAN environment, when a carrier-side link failure occurs, switchover on the carrier side can take a few hundred milliseconds. During that time, a lag in the sending and receiving of packets can occur. Use Link Debounce to hold the connection path until the switchover is complete. You can configure Link Debounce on each port.
Link Debounce works only on Layer 1 protocol applications. Layer 2 / Layer 3 protocols make decisions based on how they receive packets. For example, STP makes the decision according to the lack of traffic and port up condition;OSPF and Intermediate System to Intermediate System IS-IS can still fail adjacencies.
Note
You can not configure Link Debounce on Insight ports.
