Global Level Commands Generated
After auto-QoS srnd4 commands are applied to an interface, they 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 also generated, whch 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 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 of these eight class-maps.
The commands generate templates only as needed. For example, on first use of a new commnand, global
configurations that define the eight queue egress service-policy are generated. Subsequently, auto-QoS
applied to other interfaces do not generate templates for egress queuing. This is because all auto-QoS
commands rely on the same eight queue models after migration, already been generated from the first
use of the new command.
The global template is defined by A, B, and C.
