Cisco Cisco IOS Software Release 12.2(27)SBC

You must configure traffic classes using the class-map command.

Bandwidth-remaining ratios are only available on outbound interfaces.

The bandwidth remaining ratio command cannot coexist with another bandwidth command in 
different traffic classes of the same policy map. For example, the following configuration is not valid 
and causes an error message to display:

policy-map Prec1

class precedence_0

bandwidth remaining ratio 10

class precedence_2

bandwidth 1000

The bandwidth remaining ratio command cannot coexist with another bandwidth command in the 
same class. For example, the following configuration is not valid and causes an error message to 
display:

policy-map Prec1

class precedence_0

bandwidth 1000

bandwidth remaining ratio 10

In a hierarchical policy map in which the parent policy has only the class-default class defined with 
a child queuing policy applied, the router accepts only the bandwidth remaining ratio form of the 
bandwidth command in the class-default class of the parent policy.

The bandwidth remaining ratio command cannot coexist with the priority command in the same 
class. For example, the following configuration is not valid and causes an error message to display:

policy-map Prec1

class precedence_1

priority percent 10

bandwidth remaining ratio 10
