The very purpose of me doing ping test is to find the actual bandwidth of the circuit. If I am doing the extended ping with time-out of 1 sec, does it mean that I am sending ping packet every second ??
Is there any other elegant method using available cisco IOS commands to measure the circuit performance.
Thanx
Bala.
