I have a 6509 w sup720-10Ge and all am trying to do is have a separate voice and data queue on an uplink (which is just a gigport on a WS-X6748-GE-TX)
Again, all i want to do is have 2 queues..one for voice/one for data and trust the 46 markings coming from the lan on the other side (which is setup)
So I did this:
mls qos map dscp-cos 46 to 5
wrr-queue bandwidth 30 30 30
wrr-queue queue-limit 40 30 30
mls qos trust dscp
priority-queue cos-map 1 5
And the switch told me this when doing it:
switch#(config-if)# priority-queue cos-map 1 5
Propagating cos-map configuration to: Gi7/1 Gi7/2 Gi7/3 Gi7/4 Gi7/5 Gi7/6 Gi7/7
Gi7/8 Gi7/9 Gi7/10 Gi7/11 Gi7/12
But then I look at the config and the priority-queue cos map dissapeared from the interface config i put it on
I so much wish you can just put a "service-policy output" on the interface but it is not supported so you have to play with this wrr stuff with a priority queue and you cant even tell if its working or not..
Anyone do anything similar?
Again, just trying to preserve the DSCP46 markings coming into the switch and then queueing it outbound so it takes priority over the other (DSCP0,XYZ) traffic when there is congestion on the port.
Also, it seems you have to put in at least 3 "Wrr queue bandwidth" statements on this switch when every example i see only shows you need two; must be code or hardware
Thanks for any help
