Using ACLs to mirror traffic is considered to be flow-based mirroring since the traffic flow is defined by the ACL classification rules. This is in contrast to port mirroring, where all traffic encountered on a specific interface is replicated on another interface. What Is ACL Logging ACL Logging provides a means for counting the number of "hits" against an ACL rule. When you configure ACL Logging, you augment the ACL deny rule specification with a "log" parameter that enables hardware hit count collection and reporting. The switch uses a fixed five minute logging interval, at which time trap log entries are written for each ACL logging rule that accumulated a non-zero hit count during that interval. You cannot configure the logging interval. What Are Time-Based ACLs? The time-based ACL feature allows the switch to dynamically apply an explicit ACL rule within an ACL for a predefined time interval by specifying a time range on a per-rule basis within an ACL, so that the time restrictions are imposed on the ACL rule. With a time-based ACL, you can define when and for how long an individual rule of an ACL is in effect. To apply a time to an ACL, first you define a specific time interval and then apply it to an individual ACL rule so that it is operational only during the specified time range, for example, during a specified time period or on specified days of the week. A time range can be absolute (specific time) or periodic (recurring). If an absolute and periodic time range entry are defined within the same time range, the periodic timer is active only when the absolute timer is active. NOTE: Adding a conflicting periodic time range to an absolute time range will cause the time range to become inactive. For example, consider an absolute time range from 8:00 AM Tuesday March 1st 2011 to 10 PM Tuesday March 1st 2011. Adding a periodic entry using the 'weekend' keyword will cause the time-range to become inactive because Tuesdays are not on the weekend. 542 Configuring Access Control Lists
