Defining Time Ranges
The Time Range page enables the definition of a time period during which 802.1X is active on 802.1x-enabled ports. This Time Range must be configured with an absolute start and end time. If a time range has an absolute time range but no recurring range and it is configured to a 802.1x-enabled port, the port is 802.1x active from the absolute start time to the end time.
If a time-range includes both absolute and recurring ranges, the port is activated only if the both absolute start time and the recurring time range have been reached. The port is deactivated if either of the end times have been reached. The recurring time range is added to the absolute time range by using the Recurring Range page.
If a time range has one or more recurring ranges and is configured to a 802.1x-enabled port, the port is 802.1x active within the time period(s) defined in the recurring range(s) that are also within the absolute start and end time of the time range.
When a 802.1x-enabled port is out of its assigned time range and/or recurring time range, it is 802.1x inactive and is equivalent to Force Unauthorized.
The switch supports a maximum of 20 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 software clock should be set by the user or by SNTP. If the software clock is not set in this way, the time range is not applied.
A possible use for this feature is if you want to limit access of computers to the network only during business hours, after which they are locked, and access to the rest of the network is blocked.
