zNID 24xx Series Configuration Guide
Comparing RG, OMCI and VEIP by service, traffic forwarding
Another way to understand the three GPON interface types is by service and
traffic forwarding.
RG
With RG interfaces you can configure all service modules on the zNID 24xx.
RG VLANs pass through an integrated Etherswitch and are forwarded based
on Destination MAC to any interface, including the integrated Router. Packets
are classified on ingress and handled by the integrated Ethernet Switch and
CPU routing, voice or WiFi.
RG VLANs use the 5xx GEM exclusively (unless mapped to the VEIP, in
Dual Managed mode, in which case any GEM can be used).
See RG configured flows on page 22 for more information.
OMCI
OMCI configured ONU flows require a 1:1 UNI:GEM mapping.
OMCI configured ONU flows are cut-through flows with no bridging, no
switching, no routing.
WiFi is not supported in OMCI only mode.
Voice can operate as an OMCI-configured function or an RG-configured
function.
RG configured flows and OMCI configured flows can co-exist, but Voice
must be OMCI-configured. Remember the following rule: OMCI always
wins.
See OMCI configured ONU flows on page 24 for more information.
Dual Managed
Dual Managed connections mapped to the VEIP connections may use any
GEM. In this mode, RG VLANs operate as described above, but instead of
using the default 5xx GEM, OMCI is used to configure the GEM and VLAN
filter rule.
See Dual Managed mode using the VEIP on page 27 for more information.
RG configured flows
RG configured flows are flows configured via an RG management interface:
TR-069, Web GUI, Telnet/CLI, or SNMP. This document mainly describes
the Web GUI, so we will not go into much detail about the various
configurations in this section.
For a discussion of the configurations available and example procedures see
Deployment scenarios, page 156 and IP configuration options, page 157 .
