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 range 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

Configuration procedure

Step Command

Remarks

1.

Enter system view.

system-view N/A

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 }

No time range exists.

Displaying and maintaining time ranges

Execute the display command in any view.
