Nexus 7000 table map

[e-chuah]

Hi, I perform a "show table-map cos-dscp-map" on a Nexus 7K and the output shows "default copy". My question is what is the "default copy" mapping? I am expecting to see a cos-dscp map like what we see on a Cat6500. But it's not the case. Checked the command and configuration guide, but can't seemt to find any useful information. Appreciate if someone can give some pointers on this. Thanks Eng Wee

With nexus there are default classes for ingress can not be removed but you can change it and also they difere depending on the I/O model used like the 10G M1 has 8q4t queuing classes

So I would say follow the best practice recommendations from cisco when you implement your N7K qos

Also for your above question see the guide for older versio. I think it describe it clearer as you might need to use class and policy type of qos
