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).

console(config-if-Te1/0/1)#traffic-class-group max-bandwidth 50 90 20

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:
