B Commands
bandwidth (QoS)
To allocate a minimum percentage of the interface bandwidth to a queue and configure the bandwidth on both ingress and egress queues, use the bandwidth command. To remove a bandwidth configuration, use the no form of this command.
bandwidth { rate [ bps | kbps | mbps | gbps ] | percent percent }
no bandwidth { rate [ bps | kbps | mbps | gbps ] | percent percent }
Syntax Description
|
rate |
Bandwidth rate. The range is from 1 to 10000000000. |
|
bps |
(Optional) Specifies the units of bits per second. |

kbps |
(Optional) Specifies the units of 1000 bits per second. |
|
mbps |
(Optional) Specifies the units of megabits per second. |
|
gbps |
(Optional) Specifies the units of gigabits per second. |
|
percent |
Specifies the percentage of bandwidth of the underlying link rate. |
|
percent |
Percent value in the range from 1 to 100. |

Usage Guidelines
You can use the system-defined ingress or egress queue class for the type of module to which you want to apply the policy map. For more information about system-defined type queuing class maps, see the following table.

Examples
This example shows how to specify a bandwidth rate for a queue:
switch(config)# policy-map type queuing my_policy1 switch(config-pmap-que)# class type queuing 1p7q4t-out-pq1 switch(config-pmap-c-que)# bandwidth 10 mbps
This example shows how to remove a bandwidth rate for a queue:
switch(config)# policy-map type queuing my_policy1 switch(config-pmap-que)# class type queuing 1p7q4t-out-pq1 switch(config-pmap-c-que)# no bandwidth 10 mbps
