Configuring Time Range

Time ranges can be used to filter packets. You can specify a time range for each rule in an
ACL. A time range-based ACL takes effect only in specified time ranges. Only after a time
range is configured and the system time is within the time range, can an ACL rule take
effect.
Two types of time ranges are available:
Periodic time range, which recurs periodically on the day or days of the week.
Absolute time range, which takes effect only in a period of time and does not recur.
An absolute time range on a Switch 5500-EI can be within the range 1970/1/1 00:00 to
2100/12/31 24:00.
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.
Task
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 }
