Each port belongs to a queue-set, which defines all the characteristics of the four egress queues per port. The range is 1 to 2. Specific queue in the queue-set on which the command is performed. The range is 1 to 4. Two WTD thresholds expressed as a percentage of the queue's allocated memory. The range is 1 to 400 percent. Amount of memory to be guaranteed (reserved) for the queue and expressed as a percentage of the allocated memory. The range is 1 to 100 percent.

Defaults When quality of service (QoS) is enabled, WTD is enabled. Table 2-9 shows the default WTD threshold settings.
