Usage Guidelines
This command generates a QoS configuration for untrusted interfaces. It places a service-policy to
classify the traffic arriving from these untrusted desktops or devices and marks them accordingly. The
generated service-policies police and either mark-down or drop packets.
Global Level Commands Generated
Auto QoS srn4 commands, once applied to an interface, generate one or more of the following templates
(A, B, and C) at the global configuration level. Typically, a command generates a series of class-maps
that either match on ACLs or on DSCP or CoS values to differentiate traffic into application classes. An
input policy is generated that matches the generated classes, sets qos-groups on the classes, and in some
cases, polices the classes to a set bandwidth. (A qos-group is merely a numerical tag that allows different
application classes to be treated as one unit. Outside the switch's context, it has no significance.)
Furthermore, eight egress-queue class-maps are generated, matching the qos-groups set in the input
policy. The actual egress output policy assigns a queue to each one of these eight egress-queue
class-maps.
The commands generate the following templates as needed. For example, on initial use of the a new
command, global configurations that define the eight queue egress service-policy are generated
(template C, below). Subsequently, auto qos commands applied to other interfaces do not generate
templates for egress queuing because all auto qos commands rely on the same eight queue model after
migration, and they will have already been generated from the first use of the command.
The global templates are defined in A, B, C.
