Installing 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.
Warning
When working with two
SCE 2000
platforms 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 2000
platforms, 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 2000
platforms to the management station.(See
Connecting the
Management Interface
(on page
5-26
))
Step 3
Connect the cascade ports. (See Dual Link: Two
SCE 2000
platforms Topology.)
Step 4
Set topology configurations for each
SCE 2000
platform via the connection-mode
options. (See
Topology-Related Parameters for Redundant Topologies
(on page
6-13
).)
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
Link Mode
(on page
6-14
).)
Step 7
Make sure that the link mode is as you required. (See
Monitoring the System
(on page
6-
15
).)
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 2000
platforms Topology.)
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 2000
platforms Topology.)
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
Link Mode
(on page
6-14
).)
