CoS Interface Queue Configuration

Use the CoS 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 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.

Description
Specifies the interface (physical, LAG, or Global) to configure.
Shows the total minimum bandwidth allocated to the selected interface for all the queues.
The CoS queue. The higher the queue value, the higher its priority is for sending traffic.
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. A value of 0 (zero) means no guaranteed minimum. The sum of individual Minimum
Bandwidth values for all queues in the selected interface cannot exceed defined a maximum of 100.
The type of queue processing. Defining this value on a per-queue basis allows you to create the
desired service characteristics for different types of traffic. The options are as follows:
• Weighted Weighted round robin associates a weight to each queue. This is the default.
• Strict Strict priority services traffic with the highest priority on a queue first.
The type of queue depth management techniques used for all queues on this interface. Options are:
• Taildrop All packets on a queue are safe until congestion occurs. At this point, any additional
packets queued are dropped.
• WRED Weighted Random Early Detection (WRED) drops packets selectively based on their drop
precedence level.
