Usage Guidelines When you enter this command, the switch is in a halt mode and drops packets for a short period.
Use the wrr-queue min-reserve interface configuration command to assign one of these
minimum-reserve levels to an egress queue. The minimum-reserve level configuration is meaningless
until it is assigned to a particular queue.
Examples This example shows how to configure minimum-reserve level 5 to 20 packets on all 10/100 Ethernet
ports:
Switch(config)# mls qos min-reserve 5 20
You can verify your settings by entering the show mls qos interface buffers privileged EXEC
