Information About Topology
Topology-Related Parameters
Refer to the following sections to determine the correct values for all topology-related parameters before
beginning run the initial setup of the SCE 2000.
•
•
•
•
There are four topology-related parameters:
•
•
For backwards compatibility, the physically-connected-links parameter is currently still recognized.
Note
•
•
Any of these parameters may be configured via either the setup command or the connection-mode
command.

sce-id Parameter, page 3-12
Priority, page 3-12
On-Failure Mode Parameter, page 3-13
Connection mode — Can be any one of the following, depending on the physical installation of the
SCE 2000 (Refer to
Connection Mode Parameter, page 3-12
Inline — single SCE 2000 inline
–
Receive-only — single SCE 2000 receive-only
–
Inline-cascade — two SCE 2000 s inline
–
Receive-only-cascade — two SCE 2000 s receive-only
–
sce-id — In cascaded topologies, defines which link is connected to this SCE platform.
The sce-id parameter, which identifies the SCE platform, replaces the physically-connected-link
parameter, which identified the link. This change was required with the introduction of the SCE8000
GBE platform, which supports multiple links.
In the SCE 2000, the number assigned to the sce-id parameter (0 or 1) will be defined as the of
number of the physically connected link.
Priority — This parameter defines which is the primary SCE 2000 (Refer to
It is applicable only in a cascade topology.
On-failure — This parameter determines whether the system cuts the traffic or bypasses it when the
SCE 2000 either has failed or is booting. It is not applicable to receive-only topologies (Refer to
On-Failure Mode Parameter, page 3-13
):
