OcNOS-RON : Layer 3 Guide : Fundamental Layer 3 Command Reference : Route-Map Commands : set dampening
set dampening
Use this command to enable route-flap dampening and set parameters. Set the unreachability half-life time to be equal to, or greater than, reachability half-life time. The suppress-limit value must be greater than or equal to the reuse limit value.
Use the no parameter with this command to delete the entry.
Command Syntax
set dampening <1-45> <1-20000> <1-20000> <1-255> (<1-45>|)
no set dampening <1-45> <1-20000> <1-20000> <1-255> (<1-45>|)
Parameters
<1-45>
Reachability half-life time in minutes. The time for the penalty to decrease to one-half of its current value.
<1-20000>
Reuse-limit value. When the penalty for a suppressed route decays below the reuse value, the routes become unsuppressed.
<1-20000>
Suppress-limit value. When the penalty for a route exceeds the suppress value, the route is suppressed.
<1-255>
Max-suppress-time. Maximum time that a dampened route is suppressed.
<1-45>
Unreachability half-life time for penalty, in minutes.
Default
Default reachability half-life time: 15 minutes
Default reuse limit value: 750
Default suppress limit value: 2000
Default max-suppress value is 4 times the half-life time (60 minutes)
Default unreachability half-life time value: 15 minutes
Command Mode
Route-map mode
Applicability
This command was introduced before OcNOS version 1.3.
Example
#configure terminal
(config)#route-map R1 permit 24
(config-route-map)#set dampening 20 333 534 30
