1008 Configuring Data Center Bridging Features
It is recommended that the maximum bandwidth be configured to be greater
than the minimum bandwidth or the weight or be configured to 0 (unlimited
burst size).

9. Set the Scheduler Modes for the TCGs
This step enables strict priority scheduling on TCGs. Strict priority
scheduling on multiple TCGs prioritizes traffic from the highest numbered
TCG for transmission first. Strict priority scheduling on a single TCG selects
that TCG for transmission before the WDRR TCGs. Use the 'no' command
to disable strict priority scheduling. It is recommended that all CoS queues
enabled for strict priority scheduling be assigned to a single TCG other than
TCG0. This scheme allows a larger number of priorities to be configured as
strict priorities.
console(config-if-Te1/0/1)#traffic-class-group strict 2
To show the weight, minimum bandwidth, maximum bandwidth, and
scheduler modes of the TCGs, use the following command:
