How to Configure the Connection Mode
Use the following prodedure to configure the connection mode, including the following parameters:
•
•
•
•
To configure the connection mode, enter connection-mode inline-cascade physically-connected-links
(link-0|link-1) priority (primary|secondary) on-failure (external-bypass|bypass|cutoff) from the
SCE8000(config if)# prompt 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. If a failure occurs, the behavior of the SCE platform
is bypass.
SCE8000(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 be the secondary SCE platform. Because Link 1 was
connected to the primary, Link 0 would be connected to this SCE platform. The connection mode would
be the same as the first. If a failure occurs, the behavior of the SCE platform is also bypass.
SCE8000(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 three possible modes of operation:
•
•
•
Normally, the link mode is selected by the SCE platform software according to the configured
connection-mode. However, the link mode command can be used to enforce a specific desired mode.
This may be useful when debugging the network, or in cases where we would like the SCE platform just
to forward the traffic. (This is only relevant to inline topologies even though the configuration is
available also when in receive-only mode.)
