-auto—Select this option if the port control is based on the result of the 
authentication process. If the supplicant is authenticated, the port control 
status becomes Authorized, meaning the supplicant is granted access to 
the port. If the supplicant is not authenticated, the port control status 
becomes Unauthorized, meaning the supplicant is denied access.
 
-Force Authorized—Select this option to always allow port access...

QoS Properties

The switch supports four egress queues for each port or LAG. Queue 1 has the 
lowest priority and queue 4 has the highest priority.
The pages in the Quality of Service menu enable you to define the properties of 
the queues, and to associate to the queues the traffic that has particular 
characteristics or arrives on specific interfaces. You can also create rate limit 
profiles that define criteria for...

•trust ip-precedence—The port uses the IP Precedence value in the IP 
packet header. If no value is provided, the default priority is assigned. Non-IP 
VLAN tagged and untagged frames are assigned the default priority.
•trust ip-dscp—The por t uses the DSCP marking in the IP packet header for 
both VLAN tagged and untagged IP packets. Non-IP VLAN tagged and 
untagged frames are assigned the default...

Queue Configuration Recommendations
It is recommended that higher numbered queues be configured with higher 
priority, weight, and minimum-bandwidth settings.
The following are recommended scenarios for strict priority (SP) and WRR 
queues:
•All eight queues in SP mode (q8 > q7 > q6 > q5 > q4 > q3 > q2 > q1). q8 is 
allocated bandwidth as long as there are packets to serve in q8. Then Q7 is 
served, followed...

Mapping IP Precedence to Queues
The priority of a packet arriving at an interface can be identified by the 
Type of Service (ToS) field in an IP packet header. Eight precedence levels are 
defined (0-7). You can use the IP Precedence to Queue page to map these values 
to the four. CoS queues to steer packets to the appropriate outbound queue. 
Queue 1 has the lowest priority and queue 4 has...
