Generating traps for BGP

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.

Brocade#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 359.

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 359.

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.

Brocade(config)#snmp-server enable traps bgp
