Time Range Configuration
Time ranges can be defined and associated with commands, such as QoS
ACL, so that it is applied only during that time range.
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 Configuration
page. A recurring element can be added
to it.
•
Recurring — This is a time range element that is added to an absolute
range, and begins and ends on a recurring basis. It is defined in the Time
Range Recurrence pages.
If a time range includes both absolute and recurring ranges, the ACL is
activated only if both absolute start time and the recurring time range have
been reached. The ACL is deactivated when either of the time ranges is
reached.
The switch supports a maximum of 10 absolute time ranges.
