How to Install a Cascaded System
This section outlines the installation procedures for a redundant solution with two cascaded SCE 2000
platforms. Refer to the Cisco Service Control Engine (SCE) CLI Command Reference for details of the
CLI commands.
When working with two SCE 2000 platforms with split-flow and redundancy, it is extremely important
to follow this installation procedure.
SUMMARY STEPS
1. Install both SCE 2000 platforms, power them up, and perform the initial system configuration. (See
Installation and Maintenance and Connecting the Management Interfaces and Performing Initial
System Configuration.)
2. Connect both SCE 2000 platforms to the management station. (See Connecting the Management
Interfaces and Performing Initial System Configuration.)
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.)
4. Set topology configurations for each SCE 2000 platform via the connection-mode options. (See
Information About Topology-Related Parameters.)
5. Make sure that the SCE 2000 platforms have synchronized and active SCE 2000 platform was
selected.
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.)
7. Make sure that the link mode is as you required. (See Monitoring the System.)
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.)
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.)
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.)
11. You can now start working with the Subscriber Manager.
