BGP Policy Accounting Commands

The command-line interface (CLI) commands that you need to configure and verify BGP Policy Accounting are as follows:

• router(config-if)# bgp-policy accounting [input | output] [source]

  enables BGP policy accounting for the interface.

  - Use the optional input or output keyword to account for traffic

  either entering or exiting the router. By default, BGP policy accounting is based on traffic entering the router (input).

  - Use the optional source keyword to account for traffic based on source

  address (source lookup classification).

• Router(config-route-map)# set traffic-index bucket-number

  Applied under the route-map submenu, this command indicates where to collect output packets that pass a match clause of a route map for BGP policy accounting.

• Router(config-router)# table-map route-map-name

  Applied under the BGP process submenu, this command classifies BGP prefixes entered in the routing table and sets the traffic index next to the entries in the FIB.

• Router# show cef interface [type number] policy-statistics [input | output]

  displays the per-interface traffic statistics. You can display BGP accounting policy statistics based on traffic traveling through an input interface (input) or output interface (output) by using the appropriate keyword.

• Router# clear ip bgp [ipv4 | ipv6 | vpnv4] table-map

  reassigns the traffic indexes in case of change or removal. Note that this command does not clear the BGP Policy Accounting counters.
