Configuring Port Link-Flap Detection

To turn on or off port link-flap detection, use the following command:

configure ports [port_list | all] link-flap-detection [on | off]

To set interval, threshold (maximum number of link down events), and disable time values for link-flap detection, use the following command:

configure ports [port_list | all] link-flap-detection [{interval [interval | indefinitely]} {threshold threshold} {disable-time [disable_time | until-cleared]}]

To reset interval, threshold (maximum number of link down events), and disable time to defaults for link-flap detection, use the following command.

unconfigure ports [port_list | all] link-flap-detection {interval} {threshold} {disable-time}

To add or delete actions (disabling ports, logging events, generating SNMP traps) to be taken when excessive link-flapping is detected, use the following command:

configure ports [port_list | all] link-flap-detection action [add | delete] [{{disable-port} {log} {trap}} | all-actions]

To manually enable ports that have been disabled due to excessive link flapping, use the following command:

clear ports [port_list | all] link-flap-detection status

To clears the counters related to port link flapping, use the following command.

clear ports [port_list | all] link-flap-detection counters

To display the link-flap detection status for ports, use the following command:

show ports [port_list | all] link-flap-detection [disabled-ports | configuration | counters {refresh | no-refresh}]
