Hi
If I have 2 routers connected back to back with a cross cable, is there any way i can control the bandwidth of the channel between the router. actually i need to control the bandwidth to set up a test enviourment.
any solutions ?
thanks

You may have noticed that to bring up the link, the router connected to the DCE end of the cable required the configuration paramter "clockrate xxxx." The number is the data rate used for the link, in bits/sec. So to emulate an E1 link, set xxxx to 2000000. To emulate a 2 B-channel ISDN MLPPP link, use 128000. Use 33000 for an analog dial up. Etc.
For example, on one of my lab routers I have:
interface Serial0/0
description Link to Router 4 Serial 0
no ip address
no ip directed-broadcast
encapsulation frame-relay
no fair-queue
clockrate 1000000
If you need to emulate varing delay/packet loss behaviors, look into the NISTnet package for Linux.
Good luck and have fun!
