Brocade FastIron Ethernet Switch Layer 3 Routing Configuration Guide - Manual (Page 463)

The as-path-filternum parameter specifies one or more filters. Only the routes that have been
dampened and that match the specified filter or filters are displayed.
show ip bgp flap-statistics output descriptions TABLE 92
This field Displays
Total number of
flapping routes The total number of routes in the BGP4 route table that have changed state and 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 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 device.
Flaps The number of flaps 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 can be used
again.
Path Shows the AS-path information for the route.
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.
device# 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).
NOTE
The clear ip bgp dampening command not only clears statistics but also un-suppresses the routes.
