Cli Commands For Cascaded Systems; Topology-Related Parameters For Redundant Topologies - Cisco SCE 2000 Installation And Configuration Manual

Chapter 6 Cabling the Line Ports and Completing the Installation
Connect the cascade ports. The cascade ports must be connected directly in Layer 1 (dark fibers), not
Step 3
through switches. (See
Step 4 Set topology configurations for each SCE 2000 platform via the connection-mode options. (See
Topology-Related Parameters, page
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
Make sure that the link mode is as you required. (See
Step 7
page
Use the show interface linecard 0 link mode command.
Connect the traffic port of SCE 2000 platform #1. This will cause a momentary down time until the
Step 8
network elements from both sides of the SCE 2000 platform auto-negotiate with it and start working
(when working inline). (See
Connect the traffic port of SCE 2000 platform #2. This will cause a momentary down time until the
Step 9
network elements from both sides of the SCE 2000 platform auto-negotiate with it and start working
(when working inline). (See
When full control is needed, change the link mode on both SCE 2000 platforms on both links to
Step 10
'forwarding'. It is recommended to first configure the active SCE 2000 platform and then the standby.
(See
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.
•
•
Note For backwards compatibility, the physically-connected-links parameter is currently still recognized.

How to Set the Link Mode, page
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.
