Cisco 6500 QoS Priority Queuing (DSCP & EXP based)

Wed Nov 17 16:51:46 UTC 2010

Thanks Jim,

The line cards are 6700 series only.

It seems (i will test it) that wrr commands can only be associated with COS
marking not DSCP nor EXP.

May be Priority Queuing is not supported for MPLS traffic on 6700 modules ?
