10.2.4 Configuring per-SAP Aggregate Shapers and an
Unshaped SAP Aggregate Shaper (H-QoS)
Configuring tier 2 per-SAP aggregate shapers applies to Gen-2 SAPs configured
with 16-priority scheduling mode and Gen-3 SAPs. Access ingress and access
egress shapers are configured under the same CLI context.
Configuring a single tier 2 aggregate shaper for all unshaped SAPs applies to Gen-
2 SAPs configured with 4-priority scheduling mode. Access ingress and access
egress shapers are configured under different CLI contexts.
• Creating 16-Priority Shaped SAPs and Configuring per-SAP Aggregate Shapers
• Configuring an Unshaped Aggregate CIR for All 4-Priority Unshaped SAPs
(Access Ingress)
• Configuring an Unshaped Aggregate CIR for All 4-Priority Unshaped SAPs
(Access Egress)
10.2.4.1 Creating 16-Priority Shaped SAPs and Configuring per-
SAP Aggregate Shapers
Create shaped Gen-2 SAPs by configuring the scheduler mode to 16-priority. On
Gen-3 hardware, the scheduler mode is always 4-priority and SAPs are shaped.
Configure a shaped SAPs’ aggregate rates by setting the CIR and PIR, as required.
The SAP must be shut down before the scheduler mode and the agg-rate and cir-rate
can be changed.
Use the first CLI syntax (below) to create shaped SAPs for access egress and
access ingress for VLL and VPLS services (including routed VPLS), and the second
syntax for IES and VPRN services. Examples are given for Epipe and IES services
on Gen-2 and Gen-3 hardware:
CLI Syntax: config>service>epipe service-id customer customer-id
create
sap sap-id create
egress
scheduler-mode {4-priority | 16-priority}
agg-rate-limit agg-rate [cir cir-rate]
ingress
scheduler-mode {4-priority | 16-priority}
agg-rate-limit agg-rate [cir cir-rate]
