This display shows the following information.
You also can display all dampened routes by entering the show ip bgp dampened-paths command.
Clearing route flap dampening statistics
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
“Configuring route flap dampening” on page 37.
NOTE
The clear ip bgp dampening command not only clears statistics but also un-suppresses the routes.
Refer to
“Configuring route flap dampening” on page 37.
Generating traps for BGP4
You can enable and disable SNMP traps for BGP4. BGP4 traps are enabled by default.
To enable BGP4 traps after they have been disabled, enter the following command.
Brocade(config)# snmp-server enable traps bgp
Syntax: [no] snmp-server enable traps bgp
Use the no form of the command to disable BGP4 traps.
