Command History
Usage Guidelines You can assign the same minimum-reserve level to multiple queues. Each queue is allocated the same
amount of buffer space.
When you enter this command, the queue is temporarily shut down during the hardware reconfiguration,
and the switch drops newly arrived packets to this queue.
Examples This example shows how to configure minimum-reserve level 5 to 20 packets and assign
minimum-reserve level 5 to egress queue 1 on a port:
Switch(config)# mls qos min-reserve 5 20
Switch(config)# interface fastethernet0/1
Switch(config-if)# wrr-queue min-reserve 1 5
You can verify your settings by entering the show mls qos interface buffers privileged EXEC command.
