[c-nsp] Available bandwidth less than actual link speed - QoS on 4500 Sup6e

[Arie Vayner]

Tom,

On Sup6e you just use MQC.
It would look like:

policy-map Shape-500M
  class class-default
    shape average 500000

int gig0/0
  service-policy shape-500M out

(double check the syntax as I am typing from memory)
