min bandwidth-value: Sets the minimum guaranteed bandwidth in kbps for a queue when the interface is congested. The value range for the bandwidth-value argument is:
40 to 1000000 for GE interfaces
40 to 10000000 for 10-GE interfaces
40 to 40000000 for 40-GE interfaces
40 to 100000000 for 100-GE interfaces
Usage guidelines
You must use the qos wfq command to enable WFQ before you can configure this command on an interface.
When you use this command to configure the minimum guaranteed bandwidth for multiple queues on an interface, make sure the sum of the minimum guaranteed bandwidth is no greater than the CIR configured on the interface by using the qos gts any cir committed-information-rate command and the interface bandwidth.
Examples
# Set the minimum guaranteed bandwidth to 100 kbps for queue 0 on GigabitEthernet 2/0/1.
<Sysname> system-view [Sysname] interface GigabitEthernet 2/0/1 [Sysname-GigabitEthernet2/0/1] qos wfq weight [Sysname-GigabitEthernet2/0/1] qos bandwidth queue 1 min 100
