Installing a Cascaded System

This section outlines the installation procedures for a redundant solution with two cascaded SCE 2000s. Refer to the Cisco Service Control Engine (SCE) CLI Command Reference for details of the CLI commands.

Warning When working with two SCE 2000s with split-flow and redundancy, it is extremely important to follow this installation procedure.

To install a cascaded system, complete the following steps:

Step 1 Install both SCE 2000s, power them up, and perform the initial system configuration. (See Installation and Maintenance (on page 4-1) and Connecting the Management Interfaces and Performing Initial System Configuration (on page 5-1).)

Step 2 Connect both SCE 2000s to the management station.(See Connecting the Management Interface (on page 5-25))

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 (on page 6-4).)

Step 4 Set topology configurations for each SCE 2000 via the connection-mode options. (See Topology- Related Parameters for Redundant Topologies (on page 6-10).)

Step 5 Make sure that theSCE 2000s have synchronized and active SCE 2000 was elected.

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 2000s on both links. The bypass mode will be applied only to the active SCE 2000. (See Link Mode (on page 6-11).)

Step 7 Make sure that the link mode is as you required. (See Monitoring the System (on page 6-12).)

Use the show interface linecard 0 link mode command.

Step 8 Connect the traffic port of SCE 2000 #1. This will cause a momentary down time until the network elements from both sides of the SCE 2000 auto-negotiate with it and start working (when working inline). (See Dual Link: Two SCE 2000s Topology (on page 6-4).)
