4.5 Time Range Management 
If a configured ACL is needed to be effective in a specified time-range, a time-range should be firstly 
specified in the ACL. As the time-range based ACL takes effect only within the specified time-range, data 
packets can be filtered by differentiating the time-ranges. On this switch, absolute time and periodic time 
can be configured. Configure an absolute time section in the form of “beginning time to ending time” to 
make ACLs effective; configure a periodic time section to make ACLs effective on the fixed days of the 
week.
