Time Range Configuration

Command Usage 

◆

If a time range is already configured, you must use the 

no

 form of this 

command to remove the current entry prior to configuring a new time range.

◆

If both an absolute rule and one or more periodic rules are configured for the 
same time range (i.e., named entry), that entry will only take effect if the current 
time is within the absolute time range and one of the periodic time ranges.

Example

This example configures the time for the single occurrence of an event.

Console(config)#time-range r&d

Console(config-time-range)#absolute start 1 1 1 april 2009 end 2 1 1 april 

2009

Console(config-time-range)#

periodic

This command sets the time range for the periodic execution of a command. Use 
the 

no

 form to remove a previously specified time range.
