Subject: RE: QOS Groups
Jim,
It does not get propagated to the rest of the network. The
point of the QoS group is that you can create a logical grouping of
traffic, apply a policy to this grouping, and not affect any other
devices in the network.
Suppose that a router has 3 connections, one to customer
"Bronze", one to customer "Gold", and one connection upstream. Traffic
from customer Gold going upstream should be treated preferentially over
traffic from customer Bronze. As the traffic from Gold comes in, we can
mark it with QoS group 1. As traffic in QoS group 1 goes upstream, we
can apply whatever policy we want.
Take the following config example:
policy-map INPUT
class class-default
set qos-group 1
!
class-map match-all GOLD
match qos-group 1
!
policy-map OUTPUT
class GOLD
bandwidth percent 50
As traffic comes in the input interface, it is marked with
qos-group 1. Class-map GOLD specifies all traffic in qos-group 1. As
traffic goes to the output interface, all traffic of qos-group 1 is
guaranteed 50% of the output queue.
