In the above table, the start-time argument along with the end-time days-of-the-week
argument specifies a periodic time range; the start-time start-date argument along with
the end-time end-date argument specifies an absolute time range.
For time ranges containing only one type of time segments,
A time range containing only one periodic time segment is active when the system
time is within the periodic time segment.
A time range containing multiple periodic time segments is active when the system
is within one of the periodic time segments.
A time range containing one absolute time segment is active when the system
time is within the absolute time segment.
A time range containing multiple absolute time segments is active when the
system time is within one of the absolute time segments.
For time ranges containing both types of time segments:
A time range containing a periodic time segment and an absolute time segment is
active when the system time is within the periodic time segment and the absolute
time segment. For example, assuming that a time range contains a periodic time
segment which is from 12:00 to 14:00 every Wednesday and an absolute time
range which is from 00:00 2004/1/1 to 23:59 2004/12/31, the time range is active
when the system time is within 12:00 to 14:00 every Wednesday in 2004.
A time range containing multiple absolute time segments and multiple periodic
time segments is active when the system time is within one of the absolute time
segments and one of the periodic time segments.
Note:
You cannot configure multiple periodic time segments and multiple absolute time
segments for the same time range at a time. To configure multiple absolute/periodic
time segments for a time range, you need to execute the time-range command
repeatedly, with the time-name argument being the same.
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).
1.2.3 Defining and Applying a Flow Template
Flow template is used for traffic classification. It specifies the rules according to which
traffic classification is performed. For example, with a template defining a quadruple
containing source IP address, destination IP, source TCP port, and destination TCP
