Hello,
I have a little doubt about EFP & QoS scale on -TR A9K linecard.
I understood that -TR support a smaller amount of EFP per LC and ony 8 queues on the egress side but I'm a bit confused about policers.
I'm planning to use ASR9K mainly for aggregation/pre-aggregation MPLS network. (I'm not going to use as BNG/MSE).
For every service-instance on the access-faced interfaces I need to police the traffic using CoS value and mark with EXP bit.
On the core-faced interfaces (MPLS) I have only 4 queues.
This is an example of a working configuration on a C7600 with ES+ cards.
EFP on AC (L2) interface
service instance 1 ethernet
description CUSTOMER NAME
encapsulation dot1q 3200 second-dot1q 2
rewrite ingress tag pop 2 symmetric
service-policy input POLICY
xconnect x.x.x.x xxxxx encapsulation mpls
mtu 9000
policy-map POLICY
class cos012
police cir 4096000 bc 9216 conform-action set-mpls-exp-imposition-transmit 2 exceed-action set-mpls-exp-imposition-transmit 4

class class-default
police cir 64000 bc 9216 conform-action drop exceed-action drop
On the egress interface I will have this policy-map applied:
policy-map PORTBASED-EGRESS-QOS-CORE
class EXP-5
police 300000000
priority level 1
class EXP-367
police 500000000
priority level 2
class EXP-24
bandwidth percent 16
random-detect
random-detect precedence 2 32000 32000 1
random-detect precedence 4 23000 32000 1
class class-default
bandwidth percent 4
random-detect
random-detect precedence 0 5800 8100 1
random-detect precedence 1 8100 8100 1
My question is:
The input policer that I'm going to apply on the service-instance needs a unique queue ?
Many Thanks
Davide
