Hqos Configuration Task List - H3C S5820X Series Configuration Manual

Forwarding profile
A forwarding profile comprises a set of traffic control actions, including the queue scheduling algorithm,
scheduling weight, and traffic shaping parameters. You can associate a forwarding profile with a
forwarding group to set the scheduling priority and bandwidth resources for the forwarding group.
Scheduler policy
A scheduler policy is a set of forwarding group and forwarding profile associations. To implement HQoS
on a port, apply a scheduler policy to the port.
Scheduling layer
The scheduling layer is where a forwarding group is scheduled by HQoS. The HQoS scheduling
hierarchy comprises layer 1 and layer 2, as shown in
Instantiation
Instantiation maps packets to different forwarding groups according to match criteria, for example, maps
packets from VLAN 1 through VLAN 10 to forwarding groups FG I_1 through FG I_10, as shown in
Figure 27. You can classify traffic and map them to different forwarding groups by configuring
instantiation rules (match criteria). Then, HQoS schedules packets in a forwarding group according to
the forwarding profile associated with the forwarding group.

HQoS configuration task list

HQoS configuration organizes a tree-shaped scheduler policy model. First create forwarding groups,
then nest forwarding groups and specify a forwarding profile for each forwarding group, and at last,
instantiate each forwarding group to assign traffic to forwarding groups.
Perform the following tasks to configure HQoS:
Task
Configuring a forwarding profile
Configuring a forwarding group
Configuring a scheduler policy
Instantiating a forwarding group
Applying a scheduler policy to a port
Copying a forwarding group
Copying a scheduler policy

Remarks
Required
Required
Nest forwarding groups and specify a forwarding profile for each
child forwarding group.
Required
Create a scheduler policy, nest layer-1 forwarding groups in the
scheduler policy, and specify a forwarding profile for each layer-1
forwarding group.
Required
Instantiate the forwarding groups and specify forwarding profiles
for forwarding groups.
For example, configure layer-1 forwarding group A1 to match
traffic with local precedence 0 and use forwarding profile A1 to
process the matching traffic, and configure layer-2 forwarding
group B1 to match traffic from VLAN 1 and use forwarding profile
B1 to process the matching traffic.
