Configuring Guaranteed Minimum Bandwidth forOutbound Traffic

For any port or group of ports you can configure either the default minimum bandwidth settings for each outbound priority queue or a customized band­ width allocation. For most applications, ProCurve recommends configuring GMB with the same values on all ports on the switch so that the outbound traffic profile is consistent for all outbound traffic. However, there may be instances where it may be advantageous to configure special profiles on connections to servers or to the network infrastructure (such as links to routers, other switches, or to the network core).

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

Configures the default minimum bandwidth allocation for the outbound priority queue for each port in < port-list>. The default values per priority queue are:

• Queue 1 (low priority): 2%• Queue 2 (low priority): 3%• Queue 3 (normal priority): 30%• Queue 4 (normal priority): 10%• Queue 5 (medium priority): 10%• Queue 6 (medium priority): 10%• Queue 7 (high priority): 15%• Queue 8 (high priority): 20%The no form of the command disables GMB for all ports in

<port-list>. In this state, which is the equivalent of setting all outbound queues on a port to 0 (zero), a high level of higher-priority traffic can starve lower-priority queues, which can slow or halt lower-priority traffic in the network. You can configure bandwidth minimums from either the global configuration level (as shown above) or from the port context level. For information on outbound port queues, refer to table 13-1,“Per-Port Outbound Priority Queues” on page 13-23.
