Chapter 3 Cisco SCE 8000 Topology and Topology-Related Parameters

Topology-Related Parameters

See the following sections to determine the correct values for all topology-related parameters before
beginning to run the initial setup of the Cisco SCE 8000:
•
•
•
•
There are four topology-related parameters:
•
•
For backward compatibility, the physically-connected-links parameter is currently still recognized.
Note
•
•
These parameters are configured via the connection-mode command.
Connection Mode Parameter, page 3-14
sce-id Parameter, page 3-14
Priority, page 3-14
On-Failure Mode Parameter, page 3-15
Connection mode—Can be any one of the following, depending on the physical installation of the
Cisco SCE 8000 (See Connection Mode Parameter, page
Inline—single Cisco SCE 8000 inline
–
Receive-only—single Cisco SCE 8000 receive-only
–
Inline-cascade—two inline Cisco SCE 8000 platforms cascaded
–
Receive-only-cascade—two receive-only Cisco SCE 8000 platforms cascaded
–
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
Cisco SCE 8000 GBE platform, which supports multiple links.
In the Cisco SCE 8000 10 GBE, the number assigned to the sce-id parameter (0 or 1) is defined as
the of number of the physically connected link.
Priority—This parameter defines which is the primary Cisco SCE 8000 (See
It is applicable only in a cascade topology
On-failure—This parameter determines whether the system cuts the traffic or bypasses it when the
Cisco SCE 8000 either has failed or is booting. Traffic bypass can be achieved either through the
external optical bypass device or through the internal bypass mechanism of the SPA interface
processor. It is not applicable to receive-only topologies. (See the
section on page 3-15.)
