Chapter 10 ACL 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: Time-Range, ACL Config, Policy Config and Policy Binding. 10.1 Time-Range 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 Time-Range Summary, Time-Range Create and Holiday Config pages. 10.1.1 Time-Range Summary On this page you can view the current time-ranges.

Chapter 10 ACL

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:

Time-Range

ACL Config, Policy Config

and

Policy Binding

10.1 Time-Range

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
