I have a lab environment and I need to somehow lower/delay t1 link interfaces. I am looking to make the links be about 128K or so. I am using wic-1dsu-t1 cards in all routers with cross over t1 cables. Can someone let me know of the command or commands to accomplish this. Setting the bandwidth is just a description so i know that won't work. Is this possible?
We can rate-limit the interface badnwdith by using the below command and any excess traffoc will be dropped
rate-limit input 1280000 192000 480000 conform-action transmit exceed-action drop
rate-limit output 1280000 192000 480000 conform-action transmit exceed-action drop

use the clock rate
That will clock out packets out based on the clock speed hence if you configure clock rate 64000 (as opposed to higher clock rates) you will notice slower response from the far end.
It's not scientific but that's one way of doing it. The proper way to do it in a LAB if you are testing production services is to use a WAN simulator.
service-module t1 timeslots 1-2
This will give you a 128kb fractional T1. There is no way to set static delay in the routers. You need a WAN simulator to effectively do that.
