Configuring the Port Debounce Timer

The port debounce timer delays notification of a link change, which can decrease traffic loss due to
network reconfiguration. You can configure the port debounce timer separately on each LAN port.
Caution Enabling the port debounce timer causes link down detections to be delayed, resulting in loss of traffic
during the debouncing period. This situation might affect the convergence and reconvergence of some
Layer 2 and Layer 3 protocols.
