Cisco 870 ATM Service-policy problem

[ar]

Hi Guys.

I encountered this problem with cisco 870 atm interface. I applied service-policy output, its being accepted but when you do a show run interface, it's not there.

is this a bug?

IOS version used is:

c870-advipservicesk9-mz.124-15.T11.bin

[ar]

anyone has experience on this?

Hi Allan,

I can't guarantee I will be able to help as I haven't had much exposure to ATM configuration, but still, I would need to see your configuration including the command you are trying to add, including the result of addition of that command.

Best regards,

Peter

allan,

I hope you have checked the log of the router when you apply this "service-policy" command on the ATM interface. The reason why I say this is because for ATM interface, based on whether the policy has shaping configured or not, we have to use vbr-nrt and then it is accepted

check this Cisco document "Where Do I Apply a QoS Service Policy on an ATM Interface?"

http://www.cisco.com/en/US/tech/tk39/tk824/technologies_tech_note09186a00800d76b5.shtml

Hope it helps

Hi.

Yes i checked the logs.

No errors.

It is actually accepting new policies but not taking effect.

Say example I have the following policy active:

policy-map VOICE-LLQ

class voice

  priority percent 70

class class-default

  random-detect

interface ATM0.1 point-to-point

ip address 10.12.1.150 255.255.255.252

pvc 0/33

  vbr-rt 2048 2048

  encapsulation aal5snap

  service-policy output VOICE-LLQ

This is running already...

I am now trying to modify this to the one below: parent/child policy.

policy-map 2M

class class-default

  shape average 2000000

  service-policy normal-2M

policy-map normal-2M

class voice

  priority percent 70

class application

  bandwidth percent 20

  class class-default

   random-detect

Policy was accepted:

(config)#int atm0.1

(config-subif)#pvc 0/33

(config-if-atm-vc)#ser

(config-if-atm-vc)#service-policy out

(config-if-atm-vc)#service-policy output hwns-2M

(config-if-atm-vc)#

But after checking:

interface ATM0.1 point-to-point

ip address 10.12.1.150 255.255.255.252

ip mtu 1500

atm route-bridged ip

pvc 0/33

  vbr-rt 2048 2048

  encapsulation aal5snap

Its not there....even with sh policy-map interface command.

I also notice I can always configure back the old policy. But it wont accept any other new policies. Even an identical policy of the first one but with new name.
