Hello Sunil,


I checked the 15.1(4)M and 15.2(2)T images but the shaping rate is the same for all of them:

R1(config-pmap-c)#shape average ?

  <1000-154400000>  Target Bit Rate (bits/sec). (postfix k, m, g optional;

                    decimal point allowed)


If you consider an upgrade, you should take into account that the 12.4(22)T (and the whole 12.4T train) is end of life.


Warm Regards,

Rose

Hello Sunil,


Unfortunately, these are the latest IOS versions so even after upgrading (be that 12.4T or 15.1), the limitation would be the same.


Warm Regards,

Rose
