Hi,

I would like to know, using which command, i can look have the application visibility (i.e. which application is using how much bandwidth).. I have heard about NBAR, but would like to take some expert view before i doing anything..What other alternatives are their? Please note that i am explicitily talking about the IOS based network monitoring, no other software/application involved.. I want to see it on CLI.. also, about NBAR, is it worth it to use, and/or any bad impacts on the performance of router or link utilization.. please help
