quesiton about command: show policy-map interface fa0/0

[ciscoroyzhang]

                   HI there,  we have following policy map applied to ingress of one of our router LAN interface (connected to internal network), can someone explain how to interpreter the last line in the blue?   thanks...

Class-map: Restrict-To-TOW-ACL-CM (match-any)

      7317390 packets, 3457964496 bytes

      30 second offered rate 55000 bps, drop rate 2000 bps

      Match: access-group name Restrict-To-TOW-ACL

                  7317390 packets, 3457964496 bytes

                  30 second rate 55000 bps

      police:

            cir 512000 bps, bc 16000 bytes

            conformed 7276608 packets, 3401664053 bytes; actions: transmit

            exceeded 41434 packets, 56467339 bytes; actions:drop

           conformed 29000 bps, exceed 0 bps

Hi Roy,

police:

            cir 512000 bps, bc 16000 bytes    --- Policing Traffic @ 512Kbps

            conformed 7276608 packets, 3401664053 bytes; actions: transmit  -- Total packets and bytes conformed so far

            exceeded 41434 packets, 56467339 bytes; actions:drop  -- Total packets and bytes dropped so far

           conformed 29000 bps, exceed 0 bps  -- Current conformed rate of traffic, if no traffic is flowing this would be 0bps. This shows you have 29kbps conformed and 0 bps exceeding.

If there is no matching traffic going through router conform would be 0, altrenatively if there is congestion and packets are dropped you can see the exceed\drop also rises to non-zero value. Packets and bytes are cumulative, they keep on adding (you can get idea from history there were drops or not) but bps is the current rate of traffic flow at a time you are looking on cli or troubleshooting any issue.

Hope That Helps.

Thanks
