Information About Topology Considerations Chapter 3 Information About Topology Information About 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 . • SCE 2000 Configuration • Connection Mode Parameter • Physically Connected Links Parameter • Priority • On-Failure Mode Parameter SCE 2000 Configuration There are four topology-related parameters: • Connection mode - Can be any one of the following, depending on the physical installation of the SCE 2000 (Refer to Connection Mode Parameter ): - 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 • Physically-connected-links - In cascaded configurations, this parameter defines the number of the link connected to this SCE 2000 (Refer to Physically Connected Links Parameter ). It is applicable only in a cascade topology. • Priority - This parameter defines which is the primary SCE 2000 (Refer to Priority ). 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 ). Any of these parameters may be configured via either the setupcommand or the connection-modecommand. Connection Mode Parameter The connection mode parameter refers directly to the physical topology in which the SCE 2000 is installed. The connection mode depends on two factors: • Inline/Receive-only : - Inline - The SCE 2000 resides on the data link between the subscriber side and the network side, thus both receiving and transmitting packets. - Receive-only - The SCE 2000 does not reside physically on the data link. Data is forwarded to the SCE 2000 via an external switch. The SCE 2000 itself receives only and does not transmit. • Cascade - Indicates a two SCE 2000 topology where the SCE 2000 are connected via the cascade ports. The connection mode parameter is determined by the physical deployment of the SCE 2000 , as follows: 3-10 Cisco SCE 2000 4xGBE Installation and Configuration Guide OL-7824-06

Information About 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
.
•
SCE 2000 Configuration
•
Connection Mode Parameter
•
Physically Connected Links Parameter
•
Priority
•
On-Failure Mode Parameter
SCE 2000 Configuration
There are four topology-related parameters:
•
Connection mode
— Can be any one of the following, depending on the physical installation of the
SCE 2000
(Refer to
Connection Mode Parameter
):
–
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
•
Physically-connected-links
— In cascaded configurations, this parameter defines the number of the
link connected to this
SCE 2000
(Refer to
Physically Connected Links Parameter
).
It is applicable only in a cascade topology.
•
Priority
— This parameter defines which is the primary
SCE 2000
(Refer to
Priority
).
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
).
Any of these parameters may be configured via either the
setup
command or the
connection-mode
command.
Connection Mode Parameter
The connection mode parameter refers directly to the physical topology in which the
SCE 2000
is
installed. The connection mode depends on two factors:
•
Inline/Receive-only
:
–
Inline
— The
SCE 2000
resides on the data link between the subscriber side and the network
side, thus both receiving and transmitting packets.
–
Receive-only
— The
SCE 2000
does not reside physically on the data link. Data is forwarded
to the
SCE 2000
via an external switch. The
SCE 2000
itself receives only and does not
transmit.
•
Cascade
— Indicates a two
SCE 2000
topology where the
SCE 2000
are connected via the cascade
ports.
The connection mode parameter is determined by the physical deployment of the
SCE 2000
, as follows:
