Nexus 5500 qos drop priority

[Patrick Colbeck]

Hi

If I have two COS values within the same queue on a 5500 port can I set drop priority for them ? I am looking at setting in contract and out of contract data rates for some VMs, setting the COS value dependant on this and then getting the 5K to be more likely to drop out of contact data.

Its whjat I would do on a 6k or 7k with assigning different tail drop thresholds to different COS values in the same queue.

Nexus 5500 does not support drop thresholds for traffic with certain CoS markings like catalyst switches.

Thats what I kind of figured after reading all the docs. Makes it a bit of a pain as there really arent quite enough queues for what I want to do.

Thats six and since we are using FCoE tehre are only 5 qos groups we can use ......

I am going to have to combine two of the above.
