Configuring the Feature
Here are the commands that are used to configure the link-flap protection
feature. They configure the feature such that link-flap events are defined
as seven link changes in three minutes, and they activate the feature on
ports 11 to 20. To configure this example, enter:
awplus> enable
awplus# configure terminal
awplus(config)# link-flap rate 7
awplus(config)# link-flap duration 180
awplus(config)# interface 1.11-1.20
awplus(config-if)# link-flap protection
awplus(config-if)# end
awplus# show link-flap
