[c-nsp] limit bandwidth on 7600 MUX-UNI port

[Arie Vayner (avayner)]

Hi,

You should create the policy-map with an aggregate policer as the
action.
Then on the physical port (the trunk) configure "mls qos vlan-based",
and apply the the policy-map you have created on the SVIs (interface
vlan) for the relevant VLAN numbers.

Because you are using an aggregate policer, it would police the
aggregate rate between the different interfaces...

Hi, All!

I need advice on the folowing problem.


We have customer-faced interface on PE-router (Cisco
7606 with rsp720-3cxl-ge). Interface in question is on
WS-X6748-SFP line card. IOS 12.2(33)SRD4 Adv. IP Svc.

This interface is configured as switchport with some vlans
on it. Also, two sub-interfaces was configured using
xconnect (EoMPLS to another PE router).

Lets say something like this:

interface GigabitEthernet1/27
  description XXXXXXXXX
  switchport
  switchport trunk encapsulation dot1q
  switchport trunk native vlan 4094
  switchport trunk allowed vlan 123-129,340,2831
  switchport mode trunk
  switchport nonegotiate
  mtu 9216
  logging event link-status
  load-interval 30
  mls qos vlan-based
  spanning-tree portfast trunk
  spanning-tree bpdufilter enable
end
!
interface GigabitEthernet1/27.160
  description XXXXXXXXXX
  encapsulation dot1Q 160
  xconnect x.x.x.x yyy160 encapsulation mpls
end
!
interface GigabitEthernet1/27.170
  description XXXXXXXXXX
  encapsulation dot1Q 170
  xconnect x.x.x.x yyy170 encapsulation mpls
end

I need to limit total bandwidth for VLANs 123,160,170
to some value (100m, for example).

I understand that there is need for aggregate policer
in this case - one was created.

But what I'm can't figure out how to apply this policer
to only thrafic in seectded vlan-s.

I can't apply service-policies on interface itself and
on sub-interfaces. Also, I'cant apply policy-map with
match vlan (or match input vlan) class-map...


Please, point me in right direction!

Thanks in advance!
