You also can display all the dampened routes by entering the show ip bgp dampened-paths
command.
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>
| neighbor <ip-addr>]
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 “Displaying route flap dampening statistics” on
page 1059.
NOTE
The clear ip bgp damping command not only clears statistics but also un-suppresses the routes.
Refer to “Displaying route flap dampening statistics” on page 1059.
Generating traps for BGP
You can enable and disable SNMP traps for BGP. BGP traps are enabled by default.
To enable BGP traps after they have been disabled, enter the following command.
PowerConnect(config)#snmp-server enable traps bgp
