Cisco Command To Monitor Bandwidth Usage To Two Subnets

Hi, What would the Cisco commands or process be on a 2811 router to monitor the incoming and outgoing bandwidth to and from two specific internal subnets - and not for all of the incoming and outgoing bandwidth on the external WAN interface ?  A site needs to monitor the incoming and outgoing bandwidth for two internal subnets only as they are going to be moved to a different location (and they want to verify the new pipe to the new location will had enough bandwidth).   TIA,

I'm not sure that I follow the requirements, but "show interface x/y" (where x is the module and y is the port) will show total packets in & out, and five minute rate counts.
If you need that kind of granularity (specific networks and/or hosts prefixes) you need to turn on netflow. You will
also need to collect the netflow data via a netflow collector. Otherwise all "show interface stats" will provide is overall interface stats.
