Clearing route flap dampening statistics

Syntax: clear ip bgp neighbor all | <ip-addr> | <peer-group-name> | <as-num> traffic
The all | <ip-addr> | <peer-group-name> | <as-num> option specifies the neighbor. The <ip-addr>
parameter specifies a neighbor by its IP interface with the Layer 3 Switch. The <peer-group-name>
specifies all neighbors in a specific peer group. The <as-num> parameter specifies all neighbors
within the specified AS. The all parameter specifies all neighbors.
Clearing route flap dampening statistics
To clear route flap dampening statistics, use the following CLI method.
NOTE
Clearing the dampening statistics for a route does not change the dampening status of the route.
To clear all the route dampening statistics, enter the following command at any level of the CLI.
PowerConnect#clear ip bgp flap-statistics
Syntax: clear ip bgp flap-statistics [regular-expression <regular-expression> | <address> <mask>
The parameters are the same as those for the show ip bgp flap-statistics command (except the
longer-prefixes option is not supported). Refer to
page 1059.
NOTE
The clear ip bgp damping command not only clears statistics but also un-suppresses the routes.

Removing route flap dampening

You can un-suppress routes by removing route flap dampening from the routes. The Layer 3 Switch
allows you to un-suppress all routes at once or un-suppress individual routes.
To un-suppress all the suppressed routes, enter the following command at the Privileged EXEC level
of the CLI.
PowerConnect#clear ip bgp damping
Syntax: clear ip bgp damping [<ip-addr> <ip-mask>]
The <ip-addr> parameter specifies a particular network.
The <ip-mask> parameter specifies the network mask.
To un-suppress a specific route, enter a command such as the following.
PowerConnect#clear ip bgp damping 209.157.22.0 255.255.255.0
This command un-suppresses only the routes for network 209.157.22.0/24.
