Cisco SCE8000 GBE Topology and Topology-Related Parameters
Connection Mode Parameter
The connection mode parameter refers directly to the physical topology in which the Cisco SCE8000
GBE is installed. The connection mode depends on two factors:
•
•
The connection mode parameter is determined by the physical deployment of the Cisco SCE8000 GBE
, as follows:
•
•
•
•
sce-id Parameter
For each of the SCE platforms in a cascaded pair, this parameter identifies the platform (0 or 1). This in
turn identifies the links, with links 0-7 on one SCE platform and links 8-15 on the other.
This parameter is then added to the slot/subslot/port designation in interface configuration commands as
well as related show command output as follows:
sce-id/slot/subslot/port
where sce-id can have a value of 0 or 1.
Priority
In a cascade topology, the user must define the priority of each Cisco SCE8000 GBE .
•
•
Note that these defaults apply only when both devices are started together. However, if the primary Cisco
SCE8000 GBE fails and then recovers, it will not revert to active status, but remains in standby status,
while the secondary device remains active
OL-19897-02
Inline/Receive-only:
Inline — The Cisco SCE8000 GBE resides on the data link between the subscriber side and
–
the network side, thus both receiving and transmitting packets.
Receive-only — The Cisco SCE8000 GBE does not reside physically on the data link. Data is
–
forwarded to the Cisco SCE8000 GBE via an external optical splitter. The Cisco SCE8000 GBE
itself receives only and does not transmit.
Cascade — Indicates a two Cisco SCE8000 GBE topology where the two Cisco SCE8000 GBE
platforms are connected via the cascade ports (10GBE interfaces).
Single Cisco SCE8000 GBE inline installation = Inline connection mode.
Single Cisco SCE8000 GBE optical splitter installation = Receive-only connection mode.
Two-platform cascaded Cisco SCE8000 GBE inline installation = Inline-cascade connection mode.
Two-platform cascaded Cisco SCE8000 GBE optical splitter installation = Receive-only-cascade
connection mode
Primary — The Primary Cisco SCE8000 GBE is active by default
Secondary — The Secondary Cisco SCE8000 GBE is the default standby.
