Scheduler Configuration
The following entities may optionally be applied per scheduler:
•
Shaper profile.
•
WFQ profile.
Network Interface Configuration
The following entities must be applied per network interface (if not configured then default
parameters will be used):
•
Network ingress policy.
•
Network egress policy.
•
Network queue policy.
The following entities may optionally be applied per network interface:
•
Shaping profile.
Network Queue Configuration
Optional parameters applied per queue (if not configured then default parameters will be used):
•
Shaping profile.
•
WRED profile.
•
WFQ profile.
Service Queue Configuration
Optional parameters applied per queue (if not configured then default parameters will be used):
•
WRED profile.
•
WFQ profile.
Order of Configuration
1.
The first configuration step defines the following policies:
o
Shaping profiles.
o
WFQ profiles.
o
WRED profiles.
2.
The second configuration step defines the scheduling policies. In the scope
of the scheduling policy individual schedulers are defined and configured.
As part of the schedulers’ configuration, it is possible to apply different
WFQ and Shaping profiles to these schedulers. For configuring scheduling
policies see section “
Scheduler Policy Commands
” in this document.
3.
The third configuration step is defining and configuring service and network
policies. Configuring service ingress and network ingress policies consists in
mapping VPT, DSCP or LSP-EXP bits in incoming traffic to internal
forwarding class and color. The FC groups in ingress policies are mapped to
queues. On the other hand service egress and network egress policies
defining mapping of internal forwarding class to the corresponding egress
