Omci Vs. Residential Gateway Management - Zhone zNID-GPON-2402 Configuration Manual

OMCI vs. Residential Gateway management

For GPON zNIDs, the zNID 24xx may be configured and managed from both
OMCI and from a residential gateway interface (CLI or Web UI). When using
both methods of management it is important to understand how each method
configures traffic flows. OMCI configured data flows are very different from
residential gateway data flows.
The zNID-GPON-24xx models support multiple management interfaces,
however for the purposes of this discussion, the management interfaces fall
into two groups, the OMCI management interface and the RG management
interfaces which includes the Web GUI, CLI and SNMP.
OMCI and RG combine for three types of management modes:
•
RG only
The RG architecture utilizes and Etherswitch, supporting MAC address
learning and forwarding (ISO layer 2 bridging) as well as routing. This
combination of bridging and routing supported by the zNID provides a
broad base of routing options. See
more information.
The RG interface supports wireless and VoIP options for SIP, SIP-PLAR
and MGCP See Voice, page 134
page 191 for more information about Voice. Most of this document
explains the RG Web UI interface.
RG only mode is also called RG or RG mode.
•
OMCI only
Data flows are handled differently for OMCI configured flows than for
the RG flows. For OMCI data flows there is a one to one mapping
between the WAN side GEM port and the LAN side UNI port. All packets
are 'cut-through' the zNID with no MAC address learning or forwarding.
The wireless interface is not supported by OMCI. However to map WiFi
to OMCI there is another type of management which combines RG and
OMCI.
OMCI only mode is also called ONU mode.
•
Dual mode: OMCI and RG
With dual mode management, the downstream LAN interfaces are
configured via the RG interface, and mapped to the Virtual Ethernet
Interface Point (VEIP). The VEIP is the common interface point between
RG features and OMCI-configured filter rules.
OMCI and RG combined mode always uses the VEIP.
