Use the Interface Queue Configuration page to define what a particular queue does by configuring switch egress queues. User-configurable parameters control the amount of bandwidth used by the queue, the queue depth during times of congestion, and the scheduling of packet transmission from the set of all queues on a port. Each port has its own CoS (Class of Service) queue-related configuration.
The configuration process is simplified by allowing each CoS queue parameter to be configured globally or per-port. A global configuration change is automatically applied to all ports in the system.

Interface Queue Configuration Fields
| Field | Description |
|---|---|
| Interface | Specifies the interface (physical, LAG (Link Aggregation Group), or Global) to configure. |
| Minimum Bandwidth Allocated | Shows the sum of individual Minimum Bandwidth values for all queues in the interface. The sum cannot exceed the defined maximum of 100. This value is considered while configuring the Minimum Bandwidth for a queue in the selected interface. |
| Queue ID | Use the menu to select the queue per interface to be configured. |
| Minimum Bandwidth | Specify the minimum guaranteed bandwidth allocated to the selected queue on the interface. Setting this value higher than its corresponding Maximum Bandwidth automatically increases the maximum to the same value. The default value is 0. The valid range is 0 to 100, in increments of 1. The value zero (0) means no guaranteed minimum. The sum of individual Minimum Bandwidth values for all queues in the selected interface cannot exceed defined maximum 100. |
| Scheduler Type | Selects the type of queue processing from the drop-down
menu. 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.
|
| Queue Management Type | Displays the type of queue depth management techniques used for all queues on this interface. This is only used if the device supports independent settings per-queue. Queue Management Type can only be Taildrop. The default value is Taildrop. All packets on a queue are safe until congestion occurs. At this point, any additional packets queued are dropped. |
