as a practice I'm trying to setup qos on my home router but so far it hasn't worked
heres what I've tried so far
------------------------------
class-map match-all Xbox360
match ip dscp 8
policy-map Xbox360
class Xbox360
priority 208 310
interface fastethernet 0/0
service-policy output Xbox360
class-map match-all game
match access-group 101
policy-map game
class game
set ip dscp 8
access-list 101 permit ip host 10.2.0.11 any
access-list 101 deny ip any any
interface fastethernet 0/1.3
service-policy input game
---------------------------
I tried wireshark on the 360 to see if it had any dscp values coming from it and it didn't
any ideas?
could my 2924M-XL switch be interfering with dscp values?

hi!
you can check with the "sh policy-map interface fa0/1.3" to see if the counters for class-map game is increasing and packets are getting marked.
Also a 2924 switch could interfere and reset the dscp values to 0. Please see if the "mls qos trust dscp" is configured on the 2924 ports.

the 2924m-xl doesn't have the mls command
thats why I was hopeing to reset the dscp on all packets from 10.2.0.11
the 2924m-xl can only go up to 12.0 IOS
the 2651 can only go up to 12.3 ios both are at the latest IOS release that they can

I just re-entered the config and did the "sh policy-map interface fa0/1.3" and the packet count is going up
what is a good priority to set?

Hi!
So that means that the traffic is getting marked... there must be something which is resetting the DSCP.
The priority reserves the bandwidth for that traffic class. So it must be set to any value that wyou want to guarantee to the traffic.

Can you SPAN (monitor session) the egress port and run wireshark on the probe to see if the traffic is sent as marked? This will point towards the 2900 for any resets.

I think its working now
the link from router to switch is a trunk and the 2924 won't do port monitor on a trunk
I don't think there would be much point in seeing the return data
thanks
