Configuration procedure
Follow these steps to configure a time range:
To do...
Enter system view
Create a time range
Note that:
If only a periodic time section is defined in a time range, the time range is active only when the
system time is within the defined periodic time section. If multiple periodic time sections are defined
in a time range, the time range is active only when the system time is within one of the periodic time
sections.
If only an absolute time section is defined in a time range, the time range is active only when the
system time is within the defined absolute time section. If multiple absolute time sections are
defined in a time range, the time range is active only when the system time is within one of the
absolute time sections.
If both a periodic time section and an absolute time section are defined in a time range, the time
range is active only when the periodic time range and the absolute time range are both matched.
Assume that a time range contains an absolute time section ranging from 00:00 January 1, 2004 to
23:59 December 31, 2004, and a periodic time section ranging from 12:00 to 14:00 on every
Wednesday. This time range is active only when the system time is within the range from 12:00 to
14:00 on every Wednesday in 2004.
If the start time is not specified, the time section starts from 1970/1/1 00:00 and ends on the
specified end date. If the end date is not specified, the time section starts from the specified start
date to 2100/12/31 23:59.
Configuration example
# Define a periodic time range that spans from 8:00 to 18:00 on Monday through Friday.
<Sysname> system-view
[Sysname] time-range test 8:00 to 18:00 working-day
[Sysname] display time-range test
Current time is 13:27:32 Apr/16/2005 Saturday
Time-range : test ( Inactive )
08:00 to 18:00 working-day
# Define an absolute time range spans from 15:00 1/28/2006 to 15:00 1/28/2008.
Use the command...
system-view
time-range time-name { start-time to end-time
days-of-the-week [ from start-time start-date ]
[ to end-time end-date ] | from start-time
start-date [ to end-time end-date ] | to
end-time end-date }
