Dears,
Topology:
Its a Carrier Supporting Carrier Scenario.
A------DS/PE--------------CORE/P---------ISP/PE-------P---------ISP/PE------B
The link between Core and ISP is back to back VRF connected via a layer 2 trunk.The ISP is creating a sub-interfaces on his 3800 router with encapsulation and vlan number. AND on Core am creating a SVI with a same vlan number and ip address within the subnet. Am trying to match packets by access-list on core and applying a dedicated bandwith for the particular customer A as per the SLA with the customer, The bandwith command is not accepted on the SVI.It give me this error, " bandwidth command is not supported for this interface"" when i try to execute the service policy output policy1234
The link between Distribution and core is 10 GIG ,I don't want to limit bandwith on distribution switch outbound direction because as i want client to use 10Gig interface between Distribution and core. I want to implement a QOS on egress interface of each VRF on Core facing to ISP
What is the alternate solution u experts can give me.
Each customer VRF for example:(Customer A) is associated with SVI virtual interface on 6500 (Core) and traffic is passed to customer B.
Configs Below:
BGP is routing protocol between CORE nd ISP.
ON 3800 router (ISP End)
int gig0/0
no shut
no ip add
int gig0/0.1
no shut
encapsulation dot1q 50
ip vrf forwarding XX
ip add 10.10.10.1 255.255.255.254
ON MY END (CORE)
int gig5/1
switchport trunk encapsulation dot1q
switch mode trunk
int vlan 50
ip vrf forwarding customer A
ip add 10.10.10.2 255.255.255.254.
Thanks

Hello Altaf,
my name is Giuseppe not quisalr or giuslar.
After having exchanged 30 posts in a few days this should be clear.
trick: if you click with left button mouse on a nickname you can find out the name of the person you are peering with in netpro.
about your questions:
I would use a single rate 3colors policer because it provides a looser control.
About your test:
in theory it is possible that packets are classified as violating.
Actually, policing uses inter-packet time arrival and packet size to decide if packet is conforming. exceeding or violating.
I have to correct previous description the comparison with the time interval is more appropriate for shaping action.
Policing is more granular in its checks.
Also there are limitations of specific hardware that can play a role.
The way you have generated traffic is also important.
Hope to help
Giuseppe

Absolutely sorry for misunderstanding ur name,
pls confirm configs for single rate as am not configuring Bc and Be becz it calculates by it own and it is reflecting the same as of previous post.
police cir 2000000 pir 4000000 conform-action transmit exceed-action transmit violate-action drop
General query:
QOS books says that when PIR configured the Be calculation is Be=PIR/32.
Giuseppe pls post me the configs if a given a pipe for 4MB then what will be configs for police with PIR included with proper BC and Be valus specified.
Appreciate ur help,
Thanks

sorry,
the configs for single rate are,
police cir 4000000 conform-action transmit exceed-action transmit violate-action drop.
