Table 147 Configure/Delete time range
Operation Command
undo time-range { time-name [ start-time to end-time
days-of-the-week [ from start-time start-date ] [ to end-time end-date ]
Delete time range
| from start-time start-date [ to end-time end-date ] | to end-time
end-date ] | all }
start-time and end-time days-of-the-week define periodic time range together.
start-time start-date and end-time end-date define absolute time range together.
If a time range only defines the periodic time range, the time range is only active
within the periodic time range.
If a time range defines only periodic time ranges (by repeating this time range
name, you can configure multiple periodic time ranges with the same name), the
time range is active only within these periodic time ranges.
If a time range only defines the absolute time range, the time range is only active
within the absolute time range.
If a time range defines only absolute time ranges (by repeating this time range
name, you can configure multiple absolute time ranges with the same name), the
time range is active only within these absolute time ranges.
If a time range defines the periodic time range and the absolute time range, the
time range is only active when the periodic time range and the absolute time
range are both matched. For example, a time range defines a periodic time range
which is from 12:00 to 14:00 every Wednesday, and defines an absolute time
range which is from 00:00 2004/1/1 to 23:59 2004/12/31. This time range is only
active from 12:00 to 14:00 every Wednesday in 2004.
If a time range defines multiple absolute time ranges and multiple periodic time
ranges, the time range is active only when periodic time ranges and absolute time
ranges are both matched, that is, take the union set of multiple absolute time
ranges and multiple periodic time ranges, and then take the intersection set of the
union set of multiple absolute time ranges and that of multiple periodic time
ranges.
If neither starting time nor end time is specified, the time range is 24 hours (00:00
to 24:00).
If no end date is specified, the time range is from the date of configuration till the
largest date available in the system.
Currently the largest time range is 1970/01/01 to 2100/12/31 in the system.
Do not configure multiple periodic time ranges and absolute time ranges for the
same time range at a time. If you need to repeat this time range, you must
configure multiple time ranges for several times.
Defining Flow Template
Flow template defines useful information used in flow classification. For example,
a template defines a quadruple: source and destination IP, source and destination
