ProSafe M5300 Switch
• Use Minimum Bandwidth to specify the minimum guaranteed bandwidth allotted to
this queue. Setting this value higher than its corresponding Maximum Bandwidth
automatically increases the maximum to the same value. Default value is 0. Valid
Range is 0 to 100 in increments of 1. The value 0 means no guaranteed minimum.
Sum of individual Minimum Bandwidth values for all queues in the selected interface
cannot exceed defined maximum (100).
• Use Scheduler Type to specify the type of scheduling used for this queue. Options
are Weighted and Strict. Defining on a per-queue basis allows the user to create the
desired service characteristics for different types of traffic.
• Weighted — Weighted round robin associates a weight to each queue. This is the
default.
• Strict — Services traffic with the highest priority on a queue first.
3. Queue Management Type displays the Queue depth management technique used for
queues on this interface. This is only used if device supports independent settings
per-queue. Queue Management Type can only be taildrop. All packets on a queue are safe
until congestion occurs. At this point, any additional packets queued are dropped.
4. Click CANCEL to cancel the configuration on the screen and reset the data on the screen to
the latest value of the switch.
5. If you make changes to the page, click APPLY to apply the changes to the system.
