define absolute time range together.
If a time range only defines the period time range, the time range is only active within
the period time range.
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 the period time range and the absolute time range, the time
range is only active when the period time range and the absolute time range are both
matched. For example, a time range defines a period 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 neither starting time nor end time is specified, the time range is 24 hours (0:00 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.
32.2.2 Defining and Applying Flow Template
I. 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 TCP
ports, and then only those traffic rules including all these elements can be sent to target
hardware and referenced for such QoS functions as packet filtering, traffic policing,
priority re-labeling. Otherwise, the rules cannot be activated on the hardware and
referenced.
Perform the following configurations in system view.

Note that the sum of all elements should not be more than 16 bytes in length. The
following table lists the length of the elements involved.
