Configuring the Command Scheduler Chapter 19 Scheduling Maintenance Jobs Send documentation comments to [email protected] - Monthly-The job is executed once a month. - Delta-The job is executed beginning at the specified start time and thereafter at user-specified intervals (days:hours:minutes). • One-time mode-The job is executed once at a user-specified time. Scheduling Guidelines Before scheduling jobs on a Cisco MDS switch, be aware of the following guidelines: • Prior to Cisco MDS SAN-OS Release 3.0(3), only users local to the switch could perform scheduler configuration. As of Cisco MDS SAN-OS Release 3.0(3), remote users can perform job scheduling using AAA authentication. • Be aware that the scheduled job can fail if it encounters one of the following situations when executing the job: - If the license has expired for a feature at the time when a job containing commands pertaining to that feature is scheduled. - If a feature is disabled at the time when a job containing commands pertaining to that feature is scheduled. - If you have removed a module from a slot and the job has commands pertaining to the interfaces for that module or slot. • Verify that you have configured the time. The scheduler does not have any default time configured. If you create a schedule and assign job(s) and do not configure the time, that schedule is not launched. • While defining a job, verify that no interactive or disruptive commands (for example, copy bootflash: file ftp: URI, write erase, and other similar commands) are specified as part of a job because the job is executed noninteractively at the scheduled time. Configuring the Command Scheduler To configure the command scheduler, follow these steps: Step 1 Step 2 Step 3 Step 4 Step 5 Step 6 Enable the scheduler. Authorize remote user access (optional). Define the job. Specify the schedule and assign jobs to the schedule. Specify the time for the schedule(s). Verify the scheduled configuration.
