PLANET EPL-1000 - Manual (Page 36)

4.2.2 Aggregate Shaper
This command lets the Host restrict the bandwidth available to the OLT for user data traffic
in each direction. This feature can be used to protect the core network from bursty
upstream flows and increase the accuracy of SLA enforcement. Aggregate bandwidth
control can be disabled by setting the parameters to zero; the feature is disabled by default.
For accurate Min SLA enforcement. recommends that the upstream aggregate shaper be
provisioned for 50-100Mbps less than the maximum bandwidth of the PON. Typical values
are 800-850Mbps.
4.2.3 Priority Range
The priority range determines how many links may be registered in each priority level. This
command should be applied immediately before registering any links, or after links are
deregistered using the Disable OLT command. It is a good idea to configure the OLT in
strict boot mode, allowing the host software time to apply this command and then explicitly
enable the OLT to register links.
The OLT must be disabled prior to applying this command; otherwise the OLT FIFOs will
become corrupt. It is recommend that this operation be performed once during the initial
bring up of the PON.
