Simulate 56kb speed on Catalyst ethernet switch port

Is there a way to downgrade or slow down an ethernet host connection running at 10Mb on a Catalyst 65xx, 3750, 3550, etc. to simulate running at 56kb? I don't have mux equipment or WAN cards. We are performing a customer benchmark, and the customer wants to slow down one of their servers to simulate what they could expect to see when the server is running at their site remotely connected to their home office via a phone line. Or is the only way to do this is to purchase a WAN card for the 65xx platform?

Re: Simulate 56kb speed on Catalyst ethernet switch port

on 3550, try to do the following. I am not sure on 65xx or 3750. I guess they are similar



mls qos

mls qos aggre set56K 56000 32 exceed drop

(I am not sure the value of 32, maybe it should be 56000*1.5/8)


build an ACL and a class-map

access-list 101 permit ip any any

class-map match-all ClassName

match access-gr 101

step 3

build a policy-map

policy-map YourPolicyName

class ClassName

police aggre set56K

step 4

under the interface which simulate 56K

mls qos trust cos

service-policy input/output YourPolicyName
