limit
6.5. Simple downlink QoS Scheduling Configuration
When the QoS is simple mode, the profile is binding in the Xe port and PON port, according to the
principle: in-bound to the queue, out-bound for scheduling and rate limiting; There is only simple
QoS scheduling mode and can not be modified in uplink; the downlink defaults to simplified QoS
scheduling mode, and can be modified.
Set the PON1 port scheduling mode for simple scheduling configuration:
OLT (config) # interface gpon-olt 1/1
OLT (config-gpon-olt1 / 1) # shutdown
OLT (config-gpon-olt1 / 1) # qos-queue-scheduler model simple OLT
(config-gpon-olt1 / 1) # no shutdown
Note
：
Modify the PON port scheduling mode, you need to disable the PON port firstly, port rate limitation
need to be reconfigured.
6.5.1. PON port configuration
When the PON port is in simple scheduling mode, the queue scheduling policy should be configured
at the exit, for example:
OLT (config) # interface gpon-onu1 / 1: 1
OLT (config-gpon-olt1 / 1) # qos-queue-scheduler 1
6.5.2. Uplink port configuration
When the PON port is simple downlink scheduling model, before scheduling of downlink queue,
packet into the queue should be configured at the entrance, i.e.the uplink port, for example:
OLT (config) # interface xe1 / 1
OLT (config-xe1 / 1) # cos-queue-map 1
6.5.3. Optional Configuration
When a speed limit is required for a downlink queue, the queue's bandwidth is configured at the exit,
i.e. PON port, for example:
OLT (config) # interface gpon-olt1 / 1
OLT (config-gpon-olt1 / 1) # qos-queue-traffic 1
When a QoS flow limit is needed for the downlink data, the PON port speed limit can be configured.
OLT (config-gpon-olt1 / 1) # rate-limit 1000 2000 egress //
downlink rate limit
