Testing LAN QoS

Guys,

How do I go about testing my LAN QoS if there is no congestion?

created an access-list

!

ip access-list standard TEST

permit host 192.168.0.1

defined a class map

!

class-map match-any TEST

          match access-group name TEST

defined a policy map

policy-map TEST

     class TEST

          set dscp af41

!

Assigned the config to my interface

int fa0/34

service policy ingres TEST

!

On my trunk interfaces i have

mls qos trust dscp

However, when I loaded up wireshark and checked a server on the LAN but the DSCP value are all 0s

Any suggestions.

The markings will be applied regardless of congestion.

Did you enable mls qos globally?

What type of hardware are you using?

Based on your config, you can test by simply pinging from a workstation running wireshark to 192.168.0.1 (which I'm assuming it is the server). The ICMP packets should have AF41.

Edison,

Thanks for the response. You were correct I did have everything in place. My problem, I was looking at the server for the marking and not the client.

Yep I did enable mls qos globally

platform is 3560

Thanks for the headsup
