Telesyn Service Guide (Ethernet Passive Optical Network (EPON))
6. Ethernet Passive Optical Network (EPON)
6.1 Overview
Refer to the Telesyn User Guide for an overview of the Ethernet Passive Optical Network implementation using
the EPON2 card and the iMG/RG that includes the ONU.
6.2 Traffic Management
This subsection highlights how traffic management is handled for the EPON configuration.
6.2.1 Classifiers
Filtering is based on VLAN and IPSOURCE address.
IPSOURCE filtering can be done:
• Statically, using ACL or user classifiers
• Dynamically, using the Auto_IP filtering option on DHCP relay.
Note the following rules for classification; these are enforced by the CLI:
• The VID match rule is required on all IP filters.
• Ingress metering is not supported.
• The user can do only FORWARD and DROP actions (e.g. can't COUNT, remark, etc.).
• There is no support for IP address masks .
• All FORWARD actions precede any DROP actions, and all DROP actions follow any FORWARD actions.
Note: These attributes are included in the summary tables in Section 17.1.
6.2.2 QoS (Traffic Queues/Priorities)
With the introduction of the Service Level Agreement (SLA) model, there is a change in how traffic is prioritized
as it flows upstream and downstream. Between the OLT and ONU, traffic management is done as follows:
• The SLA provides traffic management per VLAN
• The SLA must take into account all traffic on that VLAN (service, ping, DHCP, etc.)
