(Optional) Configuring the Validity Time Range of a Rule

(Optional) Configuring the Validity Time Range of a Rule

Context

Some services or functions are restricted within a specified period of time, for example, QoS is started only during peak hours. You can create a time range and reference the time range in an ACL applied to these services or functions so that the ACL takes effect only in the time range. The services or functions that reference the ACL are also started in the specified time range.

Deleting an ACL validity time range may cause invalidity of some ACLs. Therefore, use this command with caution.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run time-range time-name { start-time to end-time { days } &<1-7> | from time1 date1 [ to time2 date2 ] }

    A time range is created.

    By default, no time range is set.

    NOTE:
    If multiple time ranges are configured using the same time-name value, the system takes the union of periodic time ranges and the union of absolute time ranges, and then takes the intersection of the two unions as the final time range. In this example, the name test is used to configure the following time ranges:
    • Time range 1: 01.01.2010 00:00 to 31.12.2010 23:59 (absolute time range)
    • Time range 2: 8:00 to 18:00 from Monday to Friday (periodic time range)
    • Time range 3: 14:00 to 18:00 on Saturday and Sunday (periodic time range)
    The time range test includes 8:00-18:00 on Monday to Friday and 14:00-18:00 on Saturday and Sunday in 2010.

    You are advised to configure the Network Time Protocol (NTP) to ensure that devices on the network use the same system time. For the NTP configuration, see Configuring Basic NTP Functions in the CloudEngine 8800, 7800, 6800, and 5800 Series Switches Configuration Guide - Network Management.

  3. Run commit

    The configuration is committed.
