Hello,
I think it is also good to mention, that qos grop can also be set in
following ways:
CAR:
rate-limit input 2000000 1000000 1000000 conform-action transmit
exceed-action set-qos-transmit 2
Policer:
policy-map test
class class-default
police 200000 100000 100000 conform-action transmit exceed-action
set-qos-transmit 2
QOS-groups can be matched in:
CAR
rate-limit output qos-group 1 2000000 1000000 2000000 conform-action
transmit exceed-action drop
Policy-map:
class-map match-all GOLD
match qos-group 1
!
policy-map OUTPUT
class GOLD
bandwidth percent 50
(it's your example)
The only thing I would like to know if I can set QoS group in CAR and
match in class-map.
