[c-nsp] VLAN traffic shaping on Cat6500/SUP720

[Vladimir Ivashchenko]

Hi Jeff,

This was just an example to show that traffic shaping isn't working.
Initially I tried to make it work with something like this:

class-map match-all CES_traffic
  match input-interface Vlan500
class-map match-all VoIP_traffic
  match access-group name VoIP_ACL
!
policy-map DS3_voice
  class CES_traffic
    priority 3000
  class VoIP_traffic
    priority 4000
policy-map DS3
  class class-default
    shape peak 43000000 172000 172000
    service-policy DS3_voice
