shall maintain a "supported release" of software on all of its systems at all times.
A supported release is defined as a version that is no more than three releases
old or eighteen months old, whichever is less.
5.5 Fault Monitoring
There are a variety of mechanisms for monitoring fault conditions on the
M20/M40. One mechanism is to report state via the red or yellow alarm
indication on the craft panel interface. A second mechanism is extensive logging
that is done for processes in the system. The third is instrumentation through
standard and proprietary SNMP MIBs, as well as standard SNMP traps. For the
red and yellow alarm indicators on the craft panel, the user can configure a set of
conditions which trigger the visible alarm. For logging, the logging messages
are preset, but the user can configure which types of messages get logged.
5.5.1 SNMP Traps
JUNOS supports both SNMP v1 and v2 traps. The JUNOS software supports the
following SNMP traps:
SNMP v1 SNMP v2
Standard Cold start
Warm start
Link down
Link up
Authentication failure

Junos supports private Enterprise traps which are provided separately. Three
Enterprise specific MIBs are also provided :

5.5.2 Alarm Conditions
