Collecting information Diffserv


I'm implementing diffserv in a 7200 cisco router with IOS12.2(2)T. I've configured the classes and policy-maps as described in the paper

"Implementing Diffserv for End-to-End Quality of Service Overview".

This configuration is done with a wrapper in java I've made. Now I want it to do some monitoring. So I have to colect some information. But with the CLI I can't get the information by source address/destination address/dscp.

I really can't discover any command that shows the traffic related with any address. Is what I'm asking impossible or is there any way of getting this


Thanks in advance.

Re: Collecting information Diffserv


I´m really happy to find sb also working on DiffServ-Implementation.

What I did so far on monitoring the queus:

I used to qdm.tar (a Java apllication running on the Router, access via http, available on CCO),

I also decreased the average time-interval from 300 sec to 60 sec and graphed with

the Java-Application validated the marking with the DSCP as well as drops,peaks or

other queue overflows.

At least this shows me that the queuning is working as I exspected. However, at this time I have

no idea how to check the DSCP-based RED with its parameters for congestion avoidance.
