[c-nsp] N7k: Attaching a service-policy to an SVI

[Tim Stevenson]

Hi Matt, Arie,

Yes, the documentation is incorrect in that section, I will work to 
get that updated.

Arie is right, you apply qos service policies to the vlan itself, not 
the SVI, in NXOS. That's to decouple SVI creation and policy 
application for vlans.

For an L2 switchport, L3 interface, or L3 subinterface:
int x/y[.z]
  service-policy in|out foo

For an entire VLAN:
vlan x
  service-policy in|out foo

Note however that in an upcoming release (5.1) we will be changing 
that to be in line with the new IOS convention of putting VLAN config 
under the "vlan-configuration" mode, like this:

vlan configuration x
  service-policy in|out foo

That change is to decouple VLAN creation and policy application for 
VLANs (specifically to support VTP client, where you may want to tie 
a policy to a VLAN that has not been learned through VTP yet).

Hope that helps,
Tim
