Configuring Queuing and Scheduling on Inline Services Interface
To configure queuing and scheduling on an inline services interface, you need to include
scheduler-map statement at the [edit class-of-services interfaces si-/0/0/0] hierarchy
level.
[edit class-of-service]
scheduler-maps <scheduler-map-name>;
interfaces si-0/0/0; {
scheduler-map <scheduler-map-name>;
}
The queue-number 7 of the inline services interface has strict-high priority because the
timing packets received by ACX Series routers gets assigned to this queue. You can
explicitly override this strict-high priority by assigning an explicit scheduler for
queue-number 7 in the scheduler-map statement attached to inline services interface as
shown below:
[edit class-of-service]
forwarding-classes {
class <class-name> queue-number 7;
}
interfaces {
si-0/0/0{
scheduler-map scheduler-map-name;
}
}
scheduler-maps {
<map-name> {
forwarding-class <class-name> scheduler <scheduler-name>;
}
}
schedulers {
<scheduler-name> {
priority low ;
}
}
The following are the CoS limitations for inline services:
•
Inline services packets classified with packet loss priority as medium-high in the ingress
path are treated as high on the egress path.
•
When both timing and NAT services are enabled on the router, you should not classify
NAT traffic into a forwarding class mapped with queue-number 7, because if you do
so, the performance of timing services can degrade.
•
If a scheduler with queue-number 7 in the scheduler-map statement is attached to an
inline services interface, then the scheduler should be configured with strict priority,
else the timing performance can degrade.
