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 
NOTE
The clear ip bgp damping command not only clears statistics but also un-suppresses the routes. 
Refer to 
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
TABLE 63
Route flap dampening statistics
Field
Description
Total number of flapping routes
Total number of routes in the Layer 3 switch BGP4 route table that have 
changed state and thus have been marked as flapping routes.
Status code
Indicates the dampening status of the route, which can be one of the following:
> – This is the best route among those in the BGP4 route table to the route 
destination.
d – This route is currently dampened, and thus unusable.
h – The route has a history of flapping and is unreachable now.
* – The route has a history of flapping but is currently usable.
Network
The destination network of the route.
From
The neighbor that sent the route to the Layer 3 switch.
Flaps
The number of flaps (state changes) the route has experienced.
Since
The amount of time since the first flap of this route.
Reuse
The amount of time remaining until this route will be un-suppressed and thus 
be usable again.  
Path
Shows the AS-path information for the route.
