Standby State
When you enable online diagnostics on a standby AXSM card, the following tests run:
•
•
Offline Diagnostics
Offline diagnostics are destructive tests (that interfere with active traffic) and therefore run only on
standby cards.
Offline diagnostics must be scheduled using the offline start (offStart) and offline day-of-week (offDow)
parameters. The coverage (offCover) parameter specifies the length of time that the offline diagnostics
will run.
Note When an active card fails, the shelf manager must stop the diagnostics on the standby card
immediately, reset, and allow normal arbitration to occur.
When offline diagnostics is enable and scheduled, numerous tests may be run depending on the
implementation. The possible tests that may be run on the PXM45 and AXSM cards are listed in the
following sections.
