sage Guidelines

Instead of the five fields of a UNIX crontab entry as described in the syntax description table for the cron-entryargument, one of the following seven special strings can be entered:

•@yearly—An event is triggered once a year. This is the equivalent of specifying 0 0 1 1 * for the first five fields.

•@annually—Same as @yearly.

•@monthly—An event is triggered once a month. This is the equivalent of specifying 0 0 1 * * for the first five fields.

•@weekly—An event is triggered once a week. This is the equivalent of specifying 0 0 * * 0 for the first five fields.

•@daily—An event is triggered once a day. This is the equivalent of specifying 0 0 * * * for the first five fields.

•@midnight—Same as @daily.

•@hourly—An event is triggered once an hour. This is the equivalent of specifying 0 * * * * for the first five fields.

A CRON timer may not produce the intended result if the time-of-day clock is not set to the correct time. Network Time Protocol (NTP) services can be used to facilitate keeping an accurate time-of-day clock setting. For more details on NTP configuration, see the "Performing Basic System Management" chapter of the Cisco IOS Configuration Fundamentals and Network Management Configuration Guide, Release 12.3.

Examples

The following example shows how to specify that an event is triggered one time after five hours:

Router(config)# event manager applet timer-absolute

Router(config-applet)# event timer absolute time 18000

The following example shows how to specify that an event is triggered once after six minutes and six milliseconds:

Router(config)# event manager applet timer-set

Router(config-applet)# event timer countdown time 360.006 name six-minutes

The following example shows how to specify that an event is triggered at 1:01 a.m. on January 1 each year:

Router(config)# event manager applet timer-cron1

Router(config-applet)# event timer cron cron-entry 1 1 1 1 * name Jan1

The following example shows how to specify that an event is triggered at noon on Monday through Friday of every week:

Router(config)# event manager applet timer-cron2

Router(config-applet)# event timer cron cron-entry 0 12 * * 1-5 name MonFri

The following example shows how to specify that an event is triggered at midnight on Sunday every week:

Router(config)# event manager applet timer-cron3

Router(config-applet)# event timer cron cron-entry @weekly name Sunday

The following example shows how to specify that an event is triggered every five hours:

Router(config)# event manager applet timer-watch

Router(config-applet)# event timer watchdog time 18000
