There are two types of time ranges:
•Absolute —This type of time range begins on a specific date or
immediately and ends on a specific date or extends infinitely. It is created in
the Time Range pages. A recurring element can be added to it.
•Recurring — This type of time range contains a time range element that is
added to an absolute range, and begins and ends on a recurring basis. It is
defined in the Recurring Range pages.
If a time range includes both absolute and recurring ranges, the process
associated with it is activated only if both absolute start time and the recurring
time range have been reached. The process is deactivated when either of the time
ranges is reached.
The device supports a maximum of 10 absolute time ranges.
All time specifications are interpreted as local time (Daylight Saving Time does not
affect this).
To ensure that the time range entries take effect at the desired times, the system
time must be set.
The time-range feature can be used for the following:
•Limit access of computers to the network during business hours (for
example), after which the network ports are locked, and access to the rest
of the network is blocked (see Chapter 9, “Configuring Ports” and
Chapter 9, “Configuring LAG Settings”)
•Limit PoE operation to a specified period.
