Connection Mode Parameter

Connection Mode Parameter
The connection mode parameter refers directly to the physical topology in which the Cisco SCE 8000 is
installed. The connection mode depends on two factors:
•
•
The connection mode parameter is determined by the physical deployment of the Cisco SCE 8000, as
follows:
•
•
•
•

sce-id Parameter

A cascade topology supports two traffic links. In the Cisco SCE 8000 10 GBE, this parameter defines
which link is connected to which Cisco SCE 8000 platform. The name of the parameter refers to its use
in the Cisco SCE 8000 GBE platform, for which it actually defines a specific SCE platform. However,
in the case of the Cisco SCE 8000 10 GBE, simply specify the number of the physically connected link
for this parameter. Assign a value of 0 or 1.
Alternatively, you can still use the physically-connected-links parameter, which is still supported for
Tip
backward compatibility. Assign a value of link-0 or link-1.

Priority

In a cascade topology, the user must define the priority of each Cisco SCE 8000:
•
•
These defaults apply only when both devices are started together. However, if the primary Cisco SCE
8000 fails and then recovers, it does not revert to active status, but remains in standby status, while the
secondary device remains active.

Inline/Receive-only:
– Inline—Cisco SCE 8000 resides on the data link between the subscriber side and the network
side, thus both receiving and transmitting packets.
Receive-only—Cisco SCE 8000 does not reside physically on the data link. Data is forwarded
–
to the Cisco SCE 8000 via an external optical splitter. The Cisco SCE 8000 itself only receives
and does not transmit.
Cascade—Indicates a two Cisco SCE 8000 topology where the two Cisco SCE 8000 platforms are
connected via the cascade ports.
Single Cisco SCE 8000 inline installation = Inline connection mode.
Single Cisco SCE 8000 optical splitter installation = Receive-only connection mode.
Two-platform cascaded Cisco SCE 8000 inline installation = Inline-cascade connection mode.
Two-platform cascaded Cisco SCE 8000 optical splitter installation = Receive-only-cascade
connection mode.
Primary—Primary Cisco SCE 8000 is active by default
Secondary—Secondary Cisco SCE 8000 is the default standby
