ONT Profiles Configuration
20.2.1.
Cross-Connect Profile Configuration
Step 1.
To configure a cross-connect profile, you need first to specify whether the service will be routed
(transmitted through an ONT router) or bridged (use bridge connection). This can be done by changing
the
model
parameter.
Step 2.
Then you need to specify a service type in the
type
parameter. Some service types require the
iphost-eid
parameter to be set which allows you to choose a definite instance of IP interface in ONT.
Step 3.
VLAN is configured in a cross-connect profile with the help of the following parameters:
tag-
mode
,
outer-vid
,
outer-cos
,
inner-vid
,
u-vid
, and
u-cos
.
Step 4.
tag-mode
enables upstream Q-in-Q mode.
outer-vid
,
outer-cos
, and
inner-vid
specify internal
and external Q-in-Q tags correspondingly. The CoS value of the internal tag is copied from the external
one in this case. If the Q-in-Q mode is not used, only the
outer-vid
and
outer-cos
parameters are valid.
The
u-vid
and
u-cos
parameters allow a tag to be specified which will be used on the ONT side.
Step 5.
The
mac-table-entry-limit
parameter allows restriction of records number in the MAC table of
OLT for this service.
