System Time

CRON

The CRON feature supports periodic and date and time-based scheduling in SR OS. CRON can be
used, for example, to schedule Service Assurance Agent (SAA) functions or to schedule turning
on and off policies to meet "Time of Day" (TOD) requirements. CRON functionality includes the
ability to specify scripts that need to be run, when they will be scheduled, including one-time only
functionality (one-shot), interval and calendar functions. Scheduled reboots, peer turn ups, service
assurance agent tests and more can all be scheduled with CRON, as well as OAM events, such as
connectivity checks, or troubleshooting runs.
The following CRON elements are supported:

Schedule — The schedule function configures the type of schedule to run, including one-
time only (one-shot), periodic, or calendar-based runs. All runs are determined by month,
day of month or weekday, hour, minute, and interval (seconds).
Time Range — Filter (ACL) policy configurations may be enhanced to support time-
based matching by referring to a time-range policy.
Time of Day — Time of Day (TOD) suites are useful when configuring many types of
time-based policies or when a large number of subscribers or SAPs require the same type
of TOD changes. The TOD suite may be configured while using specific ingress or egress
ACLs or QoS policies, and is an enhancement of the ingress and egress CLI trees.
