How to Install a Cascaded System

This section outlines the installation procedures for a redundant solution with two cascaded Cisco
SCE8000 platforms. Refer to the Cisco Service Control Engine (SCE) CLI Command Reference for
details of the CLI commands.
When working with two Cisco SCE8000 platforms with split-flow and redundancy, it is extremely
important to follow this installation procedure.
Install both Cisco SCE8000 platforms, power them up, and perform the initial system configuration. (See
Step 1
Chapter 4, "Installing the Cisco SCE8000
Interfaces"and
To maintain link continuity at all times, including during the reload sequence and power failure events,
optical bypass modules must be installed.
Step 2 Connect both Cisco SCE8000 platforms to the management station. (See
Interface, page
Step 3 Connect the cascade ports. (See
The cascade ports must be either be connected directly in Layer 1 (dark fibers), or using the following
procedure to connect through a switch.

Set topology configurations for each Cisco SCE8000 platform via the connection-mode options. (See
Step 4
How to Configure the Connection Mode, page
Make sure that the Cisco SCE8000 platforms have synchronized and active Cisco SCE8000 platform was
Step 5
selected.
Use the show interface linecard 0 connection-mode command.
If you want to start with bypass, change the link mode to your required mode in both Cisco SCE8000
Step 6
platforms on both links. The bypass mode will be applied only to the active Cisco SCE8000 platform.
(See
Step 7 Make sure that the link mode is as you required. (See
Use the show interface linecard 0 link mode command.
Step 8 Connect the traffic port of Cisco SCE8000 platform #1. This will cause a momentary down time until
the network elements from both sides of the Cisco SCE8000 platform auto-negotiate with it and start
working (when working inline). (See

Connect port 3/2/0 from box A and port 3/3/0 from box B to a single switch. Configure them both
on the same access VLAN, which will be used only by the interfaces connected to these ports. No
other interfaces in the switch should reside on that VLAN.
Connect port 3/3/0 from box A and port 3/2/0 of box B to a switch on a different VLAN. Again, the
access ports should be configured as access ports on this VLAN, which will be used only by the
interfaces connected to these ports. No other interfaces in the switch reside on the VLAN.
