Hi Team,

I ma confused with the "bandwidth remaining percent" concept of cisco.

consider the bandwidth of 300 M and below is the queing policy configured.

*policy-map queuing-300M*
* class class-default*
*  shape average 300000000*
*  service-policy queuing-out*

*policy-map queuing-out*
* class EF*
*  priority 4096*
* class MGMT*
*  bandwidth remaining percent 1 *
* class BUSINESS*
*  bandwidth remaining percent 97 *
*  shape average 290000000*
*  service-policy BUSINESS_C*
* class default-out*
*  bandwidth remaining percent 1 *
*  shape average  150000000*

*policy-map BUSINESS_C*
* class AF4X*
*  bandwidth remaining percent 9*
*  queue-limit 8694 packets*
* class AF3X*
*  bandwidth remaining percent 14*
*  queue-limit 11184 packets*
* class AF2X*
*  bandwidth remaining percent 3*
*  queue-limit 4098 packets*
* class Rest*
*  bandwidth remaining percent 71*
*  random-detect dscp-based*
*  random-detect exponential-weighting-constant 10*
*  random-detect dscp 10 12500 37500 1*
*  random-detect dscp 12 7500 25000 1*
*  queue-limit 37500 packets*


*Now my question is what would be the actual value for Class AF4X would it
be *
*A > 25832 (this value is arrived by 300000 -Priority value and considering
this to be 100% value for remaining BW calulation) or *
*B> 26631 (this value is arrived by 300000 - Priority = resultant value 97%
and this value is considered to be 100% for subclass ie BUSINESS_C
calculation).*

Bare my English mistakes


Regards,
VJ
