Hello,

This behavior is expected for 'set' command is not supported in a nested policy.

But same policy map is configured in multiple sites routers, no issues found (on 2800 routers ).

Hello,

This could be related to the IOS for 12.2(15)T1 is a pretty old IOS release (deferred release). It is indeed a Pre-HQF image and it would be the root of the problem. I guess the working routers (2800) are using an HQF image and the policy works fine because of this fact. We have to remember that HQF was introduced with 12.4(20)T and it seems to be there are no HQF images available for 1760s (latest release is 12.4.15T1) probably because this router is already an end-of-life product:

HQF:

However, I guess that you could directly apply the policy-map pmmpls5 under the interface and it will work for it will not be a CHILD policy-map. The only limitation is that the shaping mechanism of the traffic_Shaper policy-map will not be available for you (shape average percent 95).

Thanks Jose, I will upgrade the IOS on the router and try to implement the QOS.

New IOS loaded into flash of router (cisco 1760) and gave two IOS on boot system...

boot system flash c1700-k9o3sy7-mz.124-15.T14.bin   ---- ( New IOS )

boot system flash c1700-k9o3sy7-mz.122-15.T1.bin   ---- ( Old IOS )

But router is loading with the Old IOS. Any guess idea why the router is not loading with new IOS.

Thanks

Hi

I think it should be like below.

boot system flash:c1700-k9o3sy7-mz.124-15.T14.bin

I suggest u remove the old boot statement and enter the new one.

Thanks

we can not take the rest ,as we log into the device remotely.( Router is located in other region of the globe)

If the router is not loaded with the new IOS ,then it's gone :-(

Thanks

Hello S.kanth,

My main concern is that there are no HQF images for this router so the best option will be directly applying the 2nd level policy-map. Remember that HQF was introduced with 12.4(20)T.

Regards.
