how show the bandwidth using by voice

[dennis.chan]

i'm using cisco 1751 for connecting two sites through international leased circult. i'm using 4 voice channels for communication between two sites. i'm wondering if there is a command for checking the utilization of the wan link so i can decide if i want to upgrade the international leased circuit or not.

you know, international circuit is expensive so paying for higher bandwidth needed to be careful.

thanks!

Hi,

use the load interval command to reduce the delay and after that you can see with a show interface command what's the load on the interface. For sure this will not give you an overall view. You have to determine the total BW required by you voice call and be sure that the total bandwidth used by voice and data never exceed 75% of the line rate of the link.
