Configuring time ranges
About time ranges
You can implement a service based on the time of the day by applying a time range to it. A time-based service takes effect only in time periods specified by the time range. For example, you can implement time-based ACL rules by applying a time range to them.
The following basic types of time ranges are available:
· Periodic time range—Recurs periodically on a day or days of the week.
· Absolute time range—Represents only a period of time and does not recur.
The active period of a time range is calculated as follows:
1. Combining all periodic statements.
2. Combining all absolute statements.
3. Taking the intersection of the two statement sets as the active period of the time range.
Restrictions and guidelines: Time range configuration
When you configure the ACL hardware mode, follow these restrictions and guidelines:
· If a time range does not exist, the service based on the time range does not take effect.
· You can create a maximum of 1024 time ranges, each with a maximum of 32 periodic statements and 12 absolute statements.
Procedure
1. Enter system view.
system-view
2. Create or edit a time range.
time-range time-range-name { start-time to end-time days [ from time1 date1 ] [ to time2 date2 ] | from time1 date1 [ to time2 date2 ] | to time2 date2 }
If an existing time range name is provided, this command adds a statement to the time range.
