• Receive-only-cascade
• Physically-connected-links — For each of the cascaded SCE 2000 platforms, this
parameter defines the number of the link (Link 0 or Link 1) connected to this SCE 2000
platform.
• Priority — For each of the cascaded SCE 2000 platforms, this parameter defines whether it
is the primary or secondary device.
• On-failure — For each of the cascaded SCE 2000 platforms, this parameter determines
whether the system cuts the traffic or bypasses it when the SCE 2000 platform either has
failed or is booting.
Configuring 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 2000 platform
• primary/secondary
To configure the connection mode:
From the SCE 2000(config if)# prompt, type connection-mode inline-
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 2000 platform in a two-SCE 2000
platform inline topology. Link 1 is connected to this SCE 2000 platform and the behavior of the
SCE 2000 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 2000 platform that might be cascaded with the
SCE 2000 platform in Example 1. This SCE 2000 platform would have to be the secondary SCE
2000 platform, and Link 0 would be connected to this SCE 2000 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 2000 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
