Data Plan for Cascading Between the Master Subrack and the GE Remote Extended
Subrack (Including the Reliability of Uplink Links on the Extended Subrack)

Extending port of the
master subrack
Adding a GE remote extended subrack to a master subrack is like
adding a service board to the master subrack. You can add a GE
remote extended subrack in offline pre-deployment or automatic
discovery mode. In offline pre-deployment mode, an extending port
on the master subrack needs to be planned for adding the extended
subrack. In automatic discovery mode, an extending port does not
need to be planned, and the port where the extended subrack is
automatically discovered is used as the extending port.
Extended subrack ID The master subrack ID is always 0. After the GE remote extended
subrack is introduced, the extended subrack ID starts from 1.
Currently, a maximum of 32 extended subracks are supported.
Therefore, the extended ID ranges from 1 to 32.
In offline pre-deployment mode, an available subrack ID needs to be
specified for the extended subrack to be added. In automatic
discovery mode, the master subrack automatically allocates an
available subrack ID to the extended subrack that is confirmed.
Reliability of uplink
links on the extended
subrack
The reliability of uplink links on the extended subrack can be
enhanced using only Ethernet link aggregation, which is similar to
Ethernet link aggregation of the master subrack in upstream
transmission. When a GE remote extended subrack is used, pay
attention to the following points:
l
Link aggregation can be performed only on an ETHB extending
board, instead of between boards and only manually, instead of
using LACP.
l
If aggregation is performed for uplink links on the extended
subrack, the ETHB extending port in the aggregation group of the
master subrack must be set as the master port in the aggregation
group. The ETHB extending port refers to the extending port
specified during the offline configuration of the extended subrack
or the extended subrack port that is discovered automatically. The
master port in the aggregation group of the extended subrack can
be configured as required.
