DES-7200(config)# interface type
number
Enter interface configuration mode
DES-7200(config-if)# dampening
half-life-period reuse-threshold
suppress-threshold max-suppress
restart restart-penalty
Configure Dampening parameters on
the specified interface
half-life-period: configure the half-life
period of suppression penalty
reuse-threshold: configure the
penalty threshold to unsuppress
interface
suppress-threshold: configure the
penalty threshold to suppress
interface
max-suppress: configure maximum
suppress time
restart restart-penalty: configure the
penalty value to start suppression
DES-7200(config-if)# end
Exit interface configuration mode and
return to privilege mode
If only dampening is configured without any parameter, by default, the half-life
period of suppression penalty is 5s, the penalty threshold to suppress interface is
1000, the penalty threshold to suppress interface is 2000 and the maximum
suppress time is 20s.
To delete dampening configurations, execute "no dampening" command in the
interface configuration mode.
Configuration example:
Configure interface event suppression on switch interface FastEthernet 0/0, with
half-life period being 30 seconds, reuse threshold being 1500, suppression
threshold being 10000, and maximum suppression time being 120 seconds.
DES-7200(config)# interface FastEthernet 0/0
DES-7200(config-if)#no switchport
DES-7200(config-if)# dampening 30 1500 10000 120
