Hi there,
I have a question regarding the below config:
=================================
class-map match-any cm-prec-1-out
match ip precedence 1
class-map match-any cm-prec-0-out
match ip precedence 0
class-map match-any cm-prec-3-out
match ip precedence 3
class-map match-any cm-prec-2-out
match ip precedence 2
class-map match-any cm-prec-5-out
match ip precedence 5
class-map match-any cm-prec-4-out
match ip precedence 4
!
policy-map pm-queue
class cm-prec-5-out
priority percent 30
class cm-prec-4-out
bandwidth remaining percent 15
class cm-prec-3-out
bandwidth remaining percent 30
class cm-prec-2-out
bandwidth remaining percent 15
class cm-prec-1-out
bandwidth remaining percent 10
class cm-prec-0-out
bandwidth remaining percent 5
class class-default
fair-queue
policy-map pm-shape-queue-out
description *** Shape and Queue ***
class class-default
shape average 3000000000
service-policy pm-queue
The QoS policy is applied to he WAN facing interface:
interface TenGigabitEthernet0/1/0
bandwidth 3000000
ip address x.x.x.x 255.255.255.248
ip nat outside
ip flow ingress
service-policy output pm-shape-queue-out
======================================
this policy is applied to a ten gig interface to limit the traffic to 3 gig. The customer is not actually marking anything except PREC 5, but this is a standard qos policy by SP. The policy allows 3 gig until windows update server starts sending data on the link. After it starts the link doesnt allow more than 2.2 Gig traffic flow. The ping latency on the link increases from 10ms to 116ms. Can someone assist what looks wrong with this policy?
