Cisco Nexus 5500 Series NX-OS SAN Switching Configuration Guide, Release 7.x
Purpose
Configures one or more qos-group values to match for
classification of traffic into this class map. The range of
qos-group-values is from 2 to 5. There is no default value.
Note The Cisco Nexus 5000 Series switch can only
support a maximum of five qos-groups within this
range.
Exits qos configuration mode and enters policy-map mode.
To add a reference to the system default class that does not
match any traffic class, use the class class-default command.
Purpose
Enters global configuration mode.
Creates a named object that represents a class of traffic.
Class-map names can contain alphabetic, hyphen, or underscore
characters, are case sensitive, and can be up to 40 characters.
Configures the traffic class by matching packets based on a list
of QoS group values. Values can range from 0 to 5. QoS group
0 is equivalent to class-default and QoS group 1 is equivalent to
class-fcoe.
qos-groups 0 and 1 are reserved for default classes and
Note
cannot be configured.
Exits class-map mode and enters global configuration mode.
Creates a named object that represents a set of policies that are
to be applied to a set of traffic classes. Policy-map names can
contain alphabetic, hyphen, or underscore characters, are case
sensitive, and can be up to 40 characters.
