If there is a problem with just the data plane functionality on the line card, this will
be detected by the management process on that card. The data plane can be re-
initialized (automatically) or re-configured to fix the problem through the
management plane processor on that card. On the other hand, if there is a failure
of the line card itself, full management access to the card is still available through
the management plane, which can be used to remotely power off/power on the
card or do further trouble-shooting.

The feature health monitor in the management plane detects the failure of a
software component and automatically initiates a restart of the process. In most
cases, a restart of the feature will resolve the issue and the problem is fixed
without any manual intervention. If there is an extended failure within a very short
interval of time (typically two minutes), an alarm is raised to trigger manual
intervention for troubleshooting and restart of the feature. The Lifeline
management framework ensures that remote management access is always
available for rapid efficient manual intervention.

In traditional solutions, when there is a failure in the data plane, all access from a
remote terminal will be lost. However, lifeline ensures that remote management
access is always available.

Other failures will be handled by a mechanism called auto inband packet path
test. This mechanism checks for the health of the inband-management path.
When the test fails, the OA-780 moves in to the Lifeline Mode.

When there is any failure on the OA-780, Lifeline software detects the same, and
switches to Lifeline Mode. The Lifeline ensures that remote management access
is always available.
