SYS-LINK (System Links)
System links are packet links that originate at the Packet Interface board and
traverse various hardware components to specific endpoints. The hardware
components involved on the forward and reverse routes can be different,
depending upon the configuration and switch administration. Various types of
links are defined by their endpoints:
Recording System Link Events
The system links MO records every error encountered on the links. Most of these
events are not extraordinary unless they occur with an alarming frequency. The
events are logged as they occur, leaving a “trail” to help analyze abnormal
behavior exhibited by the endpoints attached to the links or the links themselves.
When a link goes down, an alarm is raised immediately. For EAL, INL, and PACL
link types a MINOR alarm is raised; for every other link type a WARNING alarm is
raised. Other alarming conditions that do not cause the link to go down get a
WARNING alarm, regardless of the link type.
