Configuring Time Ranges

You can use these pages to configure time ranges to use in time‐based access control list (ACL) rules. Timebased ACLs allow one or more rules within an ACL to be based on a periodic or absolute time. Each ACL rule within an ACL except for the implicit deny all rule can be configured to be active and operational only during a specific time period. The time range pages allow you to define specific times of the day and week in order to implement time‐based ACLs. The time range is identified by a name and can then be referenced by an ACL rule defined with in an ACL.

Time Range Configuration

Use this page to create a named time range. Each time range can consist of one absolute time entry and/or one or more periodic time entries.
