executed, and specifies whether the QoS
policy is applied to IPv4 or IPv6 traffic in the
class. The classname is a text string (64
characters maximum).
NOTE: Multiple class action
statements can be configured for different
traffic classes in the same policy. The
execution of QoS actions is performed in the
order in which the actions are numerically
listed in the policy.
action qos-action [action
qos-action ...]
Configures the QoS action specified by the
qos-action replaceable. The action is
executed on any packet that matches the
match criteria in the class. The action is not
executed on packets that match ignore
criteria.
The complete no form of the class action command or the no seq-number
command removes a QoS action from the policy configuration.
The following QoS commands are supported by the qos-action replaceable:
• rate-limit kbps
• priority priority-value
• ip-precedence precedence-value
• dscp dscp-value
To manage packets that do not match the match or ignore criteria in any class
in the policy, and therefore have no QoS actions performed on them, enter an
optional default class. The default class is placed at the end of a policy configuration
and specifies the QoS actions to perform on packets that are neither matched nor
ignored.
5. (Optional) To configure a default class in a policy, enter the default-class command at
the end of a policy configuration and specify one or more QoS actions to be executed on
packets that are not matched and not ignored.
Context: Class configuration
Syntax:
[no] default-class action qos-action [action qos-action ...]
Configures a default class that allows one or more QoS actions to be executed on
packets that are not matched or ignored by any of the class configurations in a
QoS policy. The default-class supports the same QoS commands as the class
ipv4 |ipv6 action command: rate-limit, priority, ip-precedence,
and dscp.
