Hi Andy,
You could do it by applying a QoS policy via Cisco-AVPair RADIUS
attributes, eg:
ip:sub-qos-policy-out=qos-policy-reset0
You would then have a policy on the 7200 something like this:
!
ip access-list extended match-ip-any
permit ip any any
!
class-map match-any class-ip-any
match access-group name match-ip-any
!
policy-map qos-policy-reset0
class class-ip-any
set ip dscp 0
!
You might be able to achieve the same without all the class-map stuff by
just using "class-default" to match and set that to zero, eg:
policy-map qos-policy-reset0
class class-default
set ip dscp 0
You would have to test. We have found result vary depending on platform
and features and so we use the "longer" way as we know it works more
consistently.
Reset the users session and you should be good to go when they next
connect.
Results can be seen using the normal "show policy-map" command, eg:
LNS#show policy-map int virtual-access 2053
We are doing this on 7204 running 12.2(33)SRD1 without any problems.
If you want to do some actual queuing/shaping then you should look to
use a parent shaper to shape to the DSL link speed with a child policy
to implement your actual QoS.
regards,
Tony.

Hi All,
I'm looking for a way to re-mark customer packets as it
enters/hits the LNS.
Eg: cust_1 --upload-->> [ LNS ] --download-->> cust_2
- In my example cust_1 and cust_2 are both on the same LNS.
- cust_1 is uploading a file to cust_2.
- Is there a way to reset the DSCP/TOS value of packets coming
from cust_1?
LNS is a Cisco 7301 running 12.2(31)SB14.
Thanks.
Andy
