ACL (Access Control List) is used to filter packets by configuring match rules and process policies
of packets in order to control the access of the illegal users to the network. Besides, ACL functions
to control traffic flows and save network resources. It provides a flexible and secured access
control policy and facilitates you to control the network security.
On this switch, ACLs classify packets based on a series of match conditions, which can be L2-L4
protocol key fields carried in the packets. A time-range based ACL enables you to implement ACL
control over packets by differentiating the time-ranges.
The ACL module is mainly for ACL configuration of the switch, including four submenus:"
Vkog/Tcpig, CEN"Eqphki, Rqnke{"Eqphki and Rqnke{"Dkpfkpi.

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, week time and holiday can be configured. Configure an absolute time
section in the form of “the start date to the end date” to make ACLs effective; configure a week time
section to make ACLs effective on the fixed days of the week; configure a holiday section to make
ACLs effective on some special days. In each time-range, four time-slices can be configured.
The Time-Range configuration can be implemented on Vkog/Tcpig" Uwooct{, Vkog/Tcpig"
Etgcvg"and Jqnkfc{"Eqphki pages.
