Granularity of Applied GMB Settings. Incremental bandwidth settings

greater than 0 and less than 100 are internally computed in steps of 1.0%. Thus,

the switch internally converts a configured bandwidth percentage to the

closest multiple of 1.0.

Impact of QoS Queue Configuration on GMB commands. Changing

the number of queues affects the GMB commands (interface bandwidth-min

and show bandwidth output) to operate only on the number of queues currently

configured. In addition, when the qos queue-config command is executed, any

previously configured bandwidth-min output settings are removed from the

startup configuration. Refer to Table 13-2 on page 13-20 for the default GMB

percentage allocations per number of queues.
