Effective Period

Effective Period

By configuring the effective period, you can apply an ACL to packets in a certain period of time.

Context

  • An effective period describes a special period of time. In practice, users may want certain ACL rules to be valid during a certain period but be invalid out of the period. That is, the ACL rules are used to filter packets based on the period of time. To implement this function, users can set one or multiple periods, and apply the periods to a rule. Then, packets are filtered based on the set periods.
  • An effective period can contain periodic time ranges and absolute time ranges. A periodic time range takes effect on a certain day in a week. An absolute time range contains the start time and the end time.

Procedure

  • Query the time range.
    1. Choose ACL > Effective Period to open the Effective Period page.
    2. Enter the name of the time range in the text box, for example, test.
    3. Click Query to display all matching records.
  • Add a time range.
    1. Choose ACL > Effective Period to open the Effective Period page.
    2. Click Create to open the Add Time Range page, as shown in Figure 2-149.

      Table 2-86 describes the parameters on the Add Time Range page.

      Parameter

      Description

      Time range name

      Indicates the name of the created effective period. This parameter is mandatory.

      Periodic Time Range

      Indicates the periodic time range.

      A periodic time range takes effect on a certain day in a week. You can create multiple periodic time ranges by clicking Add or delete all the periodic time ranges by clicking Delete.
      NOTE:

      If only one periodic time range is created in an effective period, the effective period takes effect when the current time is within the periodic time range.

      Absolute Time Range

      Indicates the absolute time range.

      An absolute time range contains the start time and the end time. You can create multiple absolute time ranges by clicking Add or delete all the absolute time ranges by clicking Delete.
      NOTE:

      If only one absolute time range is created in an effective period, the effective period takes effect when the current time is within the absolute time range.

    3. Set parameters.

      NOTE:
      • If an effective period contains an absolute time range and a periodic time range, the effective period takes effect only when the current time is within the absolute time range and the periodic time range.
      • The start time and end time of the absolute time range can be earlier than the current time.
      • The Periodic Time Range and Absolute Time Range parameters cannot be kept blank simultaneously.

    4. Click OK.
  • Modify a time range.
    1. Choose ACL > Effective Period to open the Effective Period page.
    2. Click to open the Modify Time Range page, as shown in Figure 2-150.

      Figure 2-150  Modify Time Range

      NOTE:
      • Table 2-86 describes the parameters on the Modify Time Range page.
      • The effective period name cannot be modified.
      • The periodic time range and absolute time range can only be deleted, but cannot be modified.

    3. Set parameters.
    4. Click OK.
  • Delete a time range.
    1. Choose ACL > Effective Period to open the Effective Period page.
    2. Select a record that you want to delete and click Delete. The system asks you whether to delete the record.

      NOTE:
      • To select a record, click the check box of the record.
