Port Traffic Controls Guaranteed Minimum Bandwidth (GMB) 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 12-1, "Per-Port Outbound Priority Queues" on page 12-11. 12-14
