QoS,Percentage-Based Policing

Answered Question
Aug 4th, 2008

Hello,

When trying to configure "QoS,Percentage-Based Policing",

on a 7600-SIP-400 with SPA-2X1GE, I get the following error:

WAN#conf t

Enter configuration commands, one per line. End with CNTL/Z.

WAN(config)#interface GigabitEthernet2/0/0

WAN(config-if)#service-policy output WAN-OUTPUT-CWT

priority percent command is not supported for this interface

Configuration failed!

!

policy-map WAN-OUTPUT

class class-default

shape average 147000000

service-policy WAN-OUT-SEC

!

policy-map WAN-OUT-SEC

class A

priority percent 20

class B

bandwidth percent 10

class C

bandwidth percent 20

class D

bandwidth percent 50

!

I believe that the feature (i.e "priority percent") applies only

to SPA WAN ports (ATM etc).

Is this correct ?

Are you aware of any docs that state the above ?

Thank you in advance

Best Regards,Pan

Pan, look into the following Cisco documentation: http://www.cisco.com/en/US/docs/interfaces_modules/shared_port_adapters/configuration/7600series/SRD1/76ovwatm.html#wp1262692

.

The Cisco ATM SPAs support only strict priority policy maps (that is, the priority command without any parameters).

I am not aware of new ATM SPAs that would overcome this limitation. If someone knows, please post the details. Claude.

Hi!

There seems to be a difference in the policy-map that you are trying to apply and the one whose configuration you have provided.

you are trying to apply :WAN-OUTPUT-CWT

and wou have provided the config for : WAN-OUTPUT

Also which image are you exactly using? Is it 12.2(33)SRB?

In any other releases like SXF/SXH etc, the priority percent/kbps commands are not supported.

Hello,

Thank you for your reply and apologies for the typo:

Correct config follows:

WAN(config-if)#service-policy output WAN-OUTPUT

priority percent command is not supported for this interface

Configuration failed!

------------------------

The IOS is use is 12.2(33)SRA6

s72033-advipservicesk9_wan-mz.122-33.SRA6.bin

.

The feature navigator does not list any differences for QOS related features between SRA6 and SRB

.

Best regards,Pan
