Configuring Time Range
Configuring Basic ACL
Configuring Advanced ACL
Configuring Layer 2 ACL

Configuring Time Range
Time ranges can be used to filter packets. You can specify a time range for each rule in an ACL. A time
range-based ACL takes effect only in specified time ranges. Only after a time range is configured and
the system time is within the time range, can an ACL rule take effect.
Two types of time ranges are available:
Periodic time range, which recurs periodically on the day or days of the week.
Absolute time range, which takes effect only in a period of time and does not recur.
