We have QoS setup and I'm trying to understand part of it to track down an issue I'm having with video packet loss.
This is the external interface on my 3825 router.
interface GigabitEthernet0/1
bandwidth 100000
ip flow ingress
ip flow egress
ip route-cache flow
load-interval 30
duplex full
speed 100
media-type rj45
service-policy input cache
service-policy output 100M-Shaper
Here is the policy-map
policy-map ISP-CE
class Voice-RoomVideo
priority percent 15
class Network-Control
bandwidth percent 5
class Internetwork-Control
bandwidth percent 2
class Desktop-Video
bandwidth percent 25
fair-queue
random-detect dscp-based
class Signaling
bandwidth percent 3
class Transactional-Data
bandwidth percent 30
fair-queue
random-detect dscp-based
class Bulk-Data
bandwidth percent 5
fair-queue
random-detect dscp-based
class Scavenger
bandwidth percent 1
set dscp default
class class-default
bandwidth percent 14
fair-queue
random-detect dscp-based
policy-map cache
class cache
police rate percent 15 peak-rate percent 20
policy-map 100M-Shaper
class class-default
shape average 100000000
service-policy ISP-CE
The policy-map 100M-Shaper, looks like it is shaping to 100M for the default class? But then it calls in the ISP-CE policy after the default class is taken care of?
Solved! Go to Solution.

What you're seeing is a hierarchical policy. The child/subordinate policy determines how the shaped traffic is managed.
