Guaranteed Minimum Bandwidth (GMB)

Syntax: [ no ] int < port-list> bandwidth-min output

[ < queue1% > < queue2% > < queue3% > < queue4% > <queue5%> <queue6%> <queue7%> <queue8%>]

For ports in < port-list>, specifies the minimum outbound bandwidth as a percent of the total bandwidth for each outbound queue. The queues receive service in descending order of priority. You must specify a bandwidth percent value for all eight queues, and the sum of the bandwidth percentages must not exceed 100%. (0 is a value for a queue percentage setting.) Configuring a total of less than 100% across the eight queues results in unallocated bandwidth that remains harmlessly unused unless a given queue becomes oversubscribed. In this case, the unallocated bandwidth is apportioned to oversubscribed queues in descending order of priority. For example, if you configure a minimum of 10% for queues 1 - 7, and 0% for queue 8, then the unallocated bandwidth will be available to all eight queues in the following prioritized order:

1.Queue 8 (high priority)2.Queue 7 (high priority)3.Queue 6 (medium priority)4.Queue 5 (medium priority)5.Queue 4 (normal priority)6.Queue 3 (normal priority)7.Queue 2 (low priority)8.Queue 1 (low priority)

A setting of 0 (zero %) on a queue means that no bandwidth minimum is specifically reserved for that queue for each of the ports in < port-list>. Also, there is no benefit to setting the high-priority queue (queue 8) to 0 (zero) unless you want the medium queue (queue 4) to be able to support traffic bursts above its guaranteed minimum.
