Chapter 2 Cisco IOS Commands for the Catalyst 4500 Series Switches
auto qos voip cisco-softphone
auto qos voip cisco-softph one
To generate QoS configuration for interfaces connected to PCs running the Cisco IP SoftPhone
application and mark police traffic coming from such interfaces, use the auto qos voip interface
configuration command.
auto qos voip cisco-softphone
Syntax Description This command has no arguments or keywords.
Defaults This command has no default settings.
Command Modes Interface configur ation mode
Usage Guidelines Ports configured with auto qos voip c ommand are considered untrusted.
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 configur ation level. Typically, a command ge nerates 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 gene rated, whch matches the gen erated 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.) Furthermo re, eight egress-queue c lass-ma ps are gene rated, matc hing the qo s-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 on ly as ne eded. For exa mple, on f irst use of a new commna nd, globa l
configurations that define the eight que ue egress service-po licy are generated. Subs equently, 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.
