Configuring Type Network QoS Policies

Configuring Type Network QoS Policies
Type network qos policies can only be configured on the system qos attachment point. They are applied to
the entire switch for a particular class.

Purpose
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.
Associates a class map with the policy map, and enters
configuration mode for the specified system class.
Note The associated class map must be the same type as
the policy map type.
Specifies the MTU value in bytes.
Note The mtu-value that you configure must be less than
the value set by the system jumbomtu command.
(Optional)
Resets the MTU value in this class.
Configures a no-drop class.
Enables multicast optimization. Multicast traffic in this class
will be served by all available multicast queues.
Note Only one class in a policy map can be configured for
multicast optimization.
For the Cisco Nexus device, multicast optimization
Note
is enabled by default on class-default. You must
remove it from class-default before enabling it on a
user-defined class.
(Optional)
Disables multicast optimization.
Configures a no-drop class. If you do not specify this
command, the default policy is drop.
The operation for the drop policy is a simple tail drop,
Note
where arriving packets will be dropped if the queue
increases to its allocated size.
The pfc-cos-value range is from 0 to 7. This option is supported
only for for a ACL-based system class (which filters traffic
using criteria other than cos-based matches).
