Configuring 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 only takes effect in any time periods specified by the time range. For example, you can implement
time-based ACL rules by applying a time range to them. If a time range does not exist, the service based
on the time range does not take effect.
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.
A time range is uniquely identified by the time range name. You can create a maximum of 1024 time
ranges, each with a maximum of 32 periodic statements and 12 absolute statements. 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.
