Information About Cascaded Systems
• 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
• Physically-connected-links — For each of the cascaded SCE platforms, this parameter defines the
number of the link (Link 0 or Link 1) connected to this SCE platform.
• Priority — For each of the cascaded SCE platforms, this parameter defines whether it is the primary
or secondary device.
• On-failure — For each of the cascaded SCE platforms, this parameter determines whether the
system cuts the traffic or bypasses it when the SCE platform either has failed or is booting.
How to Configure the Connection Mode
Use the following command to configure the connection mode, including the following parameters:
• inline/receive only
• physically connected links
• behavior upon failure of the SCE platform
• primary/secondary
Step 1 From the SCE 2000(config if)# prompt, type connection-modeinline-cascade/receive-only-cascade[
physically-connected-links {link-0/link-1}] [ priority {primary/secondary}] [ on-failure
{bypass/cutoff}] and press Enter.
EXAMPLE 1
Use the following command to configure the primary SCE platform in a two-SCE platform inline
topology. Link 1 is connected to this SCE platform and the behavior of the SCE platform if a failure
occurs is bypass.
SCE 2000(config if)# connection-mode inline-cascade physically-connected-links link-1
priority primary on-failure bypass
EXAMPLE 2
Use the following command to configure the SCE platform that might be cascaded with the SCE
platform in Example 1. This SCE platform would have to be the secondary SCE platform, and Link 0
would be connected to this SCE platform, since Link 1 was connected to the primary. The connection
mode would be the same as the first, and the behavior of the SCE platform if a failure occurs is also
bypass.
SCE 2000(config if)# connection-mode inline-cascade physically-connected-links link-0
priority secondary on-failure bypass
How to Set the Link Mode
The SCE platform has an internal hardware card used to maintain the links even when the SCE platform
fails. This hardware card has four possible modes of operation:
• bypass
• forwarding
