Guaranteed Minimum Bandwidth (GMB)
GMB Operating Notes
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 12-2 on page 12-12 for the default GMB
percentage allocations per number of queues.
GMB on a Port When the Port is an Active Member of a Trunk. When
a port joins a trunk, it retains its currently configured GMB. Configuration of
GMB on a port is allowed even when it is an active member of a trunk. It is
highly recommended that you configure trunked ports so that they have the
same bandwidth-min configurations.
