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.

CoS Interface Queue Configuration

CoS Interface Queue Configuration Fields 

Field

Description

Interface

Specifies the interface (physical, LAG, or Global) to configure. 

Total Minimum Bandwidth 
Allocation (%)

Shows the total minimum bandwidth allocated to the selected interface for all the queues.

Queue ID

The CoS queue. The higher the queue value, the higher its priority is for sending traffic.

Minimum Bandwidth

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.

Scheduler Type

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.

Queue Management Type

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.
