NOTE:
•
Each time you try to associate a forwarding group with a forwarding profile, the system checks the
contents of the forwarding profile. If the forwarding profile conflicts with the forwarding group, your
association attempt will fail.
• In addition to nesting a new forwarding group in a forwarding group and associating a forwarding
profile with the newly nested forwarding group, the forwarding-group
sub-fg-name profile fp-name
command allows you to associate an existing child forwarding group in a forwarding group with a new
forwarding profile.
• You cannot nest a child forwarding group in a forwarding group with nested forwarding classes.
• A forwarding group with child forwarding groups nested cannot be nested in another forwarding
group.
• A forwarding group cannot nest itself.
Configuring an scheduler policy
NOTE:
The scheduler policy configuration conflicts with the port QoS configuration (including queue-based GTS,
port WRED, and hardware queue scheduling). For more information about port QoS, see the chapters
“Configuring traffic shaping and line rate”, “Configuring congestion avoidance”, and “Configuring
hardware congestion management”.
A scheduler policy is a set of hierarchical scheduling entities. By applying a scheduler policy in the
outbound or inbound direction of an interface, you can perform hierarchical QoS for the outgoing or
incoming traffic of the interface.
You must create a scheduler policy before organizing forwarding groups and forwarding classes into a
scheduler policy tree.
Configuring a scheduler policy includes:
• Creating an scheduler policy
• Nesting forwarding groups in the scheduler policy
Creating an scheduler policy
To create a scheduler policy:
Step Command Remarks
1. Enter system view. system-view N/A
2. Create an scheduler policy.
qos scheduler-policy sp-name [ id
sp-id ]
This command can either create a
scheduler policy or enter the view
of an existing scheduler policy.
Nesting an forwarding group in the scheduler policy
Similar to nesting child forwarding groups in a parent forwarding group, you can nest a forwarding
group in a scheduler policy by associating the forwarding group with a forwarding profile in scheduler
policy view.
You can nest multiple forwarding groups in a scheduler policy. A forwarding group can be nested in
multiple scheduler policies and associated with a different forwarding profile in each scheduler policy.
