Step 3
Connect the cascade ports. The cascade ports must be connected directly in Layer 1 (dark fibers), not
through switches. (See
Dual Link: Two SCE 2000s Topology, page 6-5
.)
Step 4
Set topology configurations for each SCE 2000
platform via the connection-mode options. (See
Topology-Related Parameters, page 3-11
.)
Step 5
Make sure that the SCE 2000 platforms have synchronized and active SCE 2000 platform was selected.
Use the
show interface linecard 0 connection-mode
command.
Step 6
If you want to start with bypass/sniffing, change the link mode to your required mode in both SCE 2000
platforms on both links. The bypass mode will be applied only to the active SCE 2000 platform. (See
How to Set the Link Mode, page 6-12
Step 7
Make sure that the link mode is as you required. (See
How to Install a Service Control Application,
.)
Use the
show interface linecard 0 link mode
command.
Step 8
Connect the traffic port of SCE 2000 platform #1. This will cause a momentary down time until the
network elements from both sides of the SCE 2000 platform auto-negotiate with it and start working
(when working inline). (See
Dual Link: Two SCE 2000s Topology, page 6-5
Step 9
Connect the traffic port of SCE 2000 platform #2. This will cause a momentary down time until the
network elements from both sides of the SCE 2000 platform auto-negotiate with it and start working
(when working inline). (See
Dual Link: Two SCE 2000s Topology, page 6-5
Step 10
When full control is needed, change the link mode on both SCE 2000 platforms on both links to
‘forwarding’. It is recommended to first configure the active SCE 2000 platform and then the standby.
(See
How to Set the Link Mode, page 6-12
.)
Step 11
You can now start working with the Subscriber Manager.
CLI Commands for Cascaded Systems
This section presents CLI commands relevant to the configuration and monitoring of a redundant system.
Topology-Related Parameters for Redundant Topologies
All four of the topology-related parameters are required when configuring a redundant topology.
•
Connection mode
— Redundancy is achieved by cascading two SCE platforms. Therefore the
connection mode for both SCE platforms may be either:
–
Inline-cascade
–
Receive-only-cascade
•
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.
Note
For backwards compatibility, the physically-connected-links parameter is currently still recognized.
