QoS - Shape not for output?

policy-map My_policy

class class_my_class

priority 32

class class-default

fair-queue

shape average 64000

If I write this policy as output of the pvc interface, Why not work? No change of the running config of the pvc. Does shape command works only on input interfaces?

Re: QoS - Shape not for output?

Shaping is always an egress function. What's not working in your case? Can you post the router config?

hi

shape works only in output direction however police work in both directions.

if you are in FRelay envirenment i thinks you have to enable : frame-relay traffic-shaping for the interface .

Re: QoS - Shape not for output?

Hi,

My router configurations:

sh run

...

interface ATM1/0.2 point-to-point

bandwidth 256

ip address 192.x.x.1 255.255.255.0

pvc 0/34

vbr-rt 256 256

oam-pvc manage

...

(config)#interface ATM1/0.2

(config-subif)#pvc 0/34

(config-if-atm-vc)#service-policy output My_policy

...

sh run interface ATM1/0.2

Building configuration...

...

interface ATM1/0.2 point-to-point

bandwidth 256

ip address 192.x.x.1 255.255.255.0

pvc 0/34

vbr-rt 256 256

oam-pvc manage

...

There is no configuration change! What is the reason?

I hope that the service-policy command should be placed next to

the "oam-pvc manage" line.

I think it works with "input" only. Take a look at this the link for more info.

Re: QoS - Shape not for output?

Your policy map is OK. You need to apply the service policy under the ATM shaping configuration i.e configure service policy under the int atm1/0.2 --> pvc 0/34 --> vbr-rt mode. Try this:

interface ATM1/0.2 point-to-point

bandwidth 256

pvc 0/34

vbr-rt 256 256

service-policy output My_policy
