I have a Cisco827-4v c820-k9osv6y6-mz.122-15.T14.bin

I am setting up QoS CBWFQ over IPsec GRE VPNs tunnels

My Issue is regarding Shaping inside my parent policy.

In class-map configuration mode inside policy-map configuration mode I can type shape average 512000 5120 command

BUT when I check running-config again

the line shape average 512000 5120 does not exist.

Any Idea?

Chek the text below

Avig_sayula#conf t

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

Avig_sayula(config)#policy-map AVIG

Avig_sayula(config-pmap)#class class-default

Avig_sayula(config-pmap-c)#shape average 512000 5120

Avig_sayula(config-pmap-c)#service-policy voice-policy

Avig_sayula#sh running-config

policy-map AVIG

class class-default

service-policy voice-policy

It could be that the command 'shape average 512000 5120' is a default value, that could be the reason that it doesn't show up in the configuration.

You'll also see that kind of behaviour when you create a ISAKMP policy with default values. Some line seem missing but they are really there.

You can double-check your configuration in the Cisco SDM (not the Express version of SDM!). It should be possible to view the contents of the policy-map there.

Please rate if the post is usefull!

I really appreciate your time.

I have tried with other parameters something like that 'shape average 128000 1280', 'shape average 384000 3840' and is the same problem

I'm not currently at a box to test with, but the class-default is a bit different from other classes. Might be a shaper isn't supported in that particular class, or you might need to state something like no fair-queue or use a bandwidth statement. Might also need to change the reserve bandwidth allocation.

Also if have logging active, check it. I've seen instances where command lines appear to be accepted, when they are actually rejected but only the syslog indicates why.

The shaper command is supported in class-default look below.

Avig_sayula(config)#policy-map AVIG

Avig_sayula(config-pmap)# class class-default


QoS policy-map class configuration commands:

bandwidth Bandwidth

drop Drop all packets

exit Exit from QoS class action configuration mode

fair-queue Enable Flow-based Fair Queuing in this Class

no Negate or set default values of a command

priority Strict Scheduling Priority for this Class

queue-limit Queue Max Threshold for Tail Drop

random-detect Enable Random Early Detection as drop policy

service-policy Configure QoS Service Policy

shape Traffic Shaping

I created another class and command shape does not show up yet in running-config also I was checking syslog messages and I did not receive nothing regarding shape command.

I stated bandwidth command first and then no fair-queue command and I can see them in running-config but shape command is not posible.

I just looked at software advisor. Didn't find your version, c820-k9osv6y6-mz.122-15.T14.bin, listed. Even though syntax accepted at command line, perhaps you need to try another version. Ones I found listed are:
