Policing; Cos-Based Qos; Egress Queuing - Supermicro SSE-X3348S Configuration Manual

the actions to perform for the traffic class of a class-map. Actions can include setting a specific DSCP
value or the action to take when the traffic is out of profile.
An ACL must be created for each policy and class-map,If more thanone type of traffic needs to be
classified, another ACL and class map can be created and associated. This relationship between the ACL,
class map and policy map is depicted below.

1.2.2 Policing

Policing involves creating a policer that specifies the bandwidth limits for the traffic. Each policer
specifies the action to take for packets thatare in or out of profile. Packets that exceedthe limits are out
of profile and various actions are carried out by the marker on out of profile packets, which may
includedropping the packet or markingdown the packet with a new user-defined value.

1.3 CoS-Based QoS

Supermicro switch features based on Class of Service (CoS) are:
Queuing
•
Scheduling
•
Bandwidth Management
•
Default Priority

1.3.1 Egress Queuing

The CoS priority of a packet is mapped to a traffic class.Supermicro switchesprovide support to configure
the mapping of CoS priority to a traffic class.Each traffic class is mapped to eight egress queues in the
switch.
