checking available bandwidth

[adnan]

I am looking to see if there is a command in cisco IOS beside checking load on the serial interfaces for availbale bandwidth. The scenario is a basic cisco 1700 series router with one serial interface with 384k circuit. There are two sub interfaces the second one is for backup. There are about 15 users and I would like to see how much bandwitdh is available when all users are on the network.

There isn't any command to see this besides the "show interface.." command. You could of course set the load-interval down to 30 seconds ("load-interval 30" in the interface-config) to make it a bit more responsive to changes.

I would recommend using an external SNMP-tool to graph or display the load. The Solarwinds-toolset has the goods you are looking for if you are running windows (http://www.solarwinds.net/Tools/Engineer/index.htm)

If you run a *nix box, you should look into MRTG/RRDTool etc. (Check out Cacti: http://www.cacti.net/)
