The samples below illustrate the initial message and periodic updates sent by an IOS device with a default configuration using the log ACE option. These periodic updates will contain the number of packets matched since the previous message. Similarly, if any log-enabled ACE in any ACL on any interface matches a packet within one second of the initial log message, the match or matches are counted for five minutes and then reported. If the log-enabled ACE matches another packet with identical characteristics to the packet that generated a log message, the number of packets matched is incremented and then reported at five-minute intervals. There are two scenarios in which subsequent log messages will not be sent immediately. The first packet logged via the log or log-input options will generate a syslog message. The log-input option enables logging of the ingress interface and source MAC address in addition to the packet's source and destination IP addresses and ports. The log and log-input options apply to an individual ACE and cause packets that match the ACE to be logged. Using the configuration commands detailed in this document, administrators can strike a balance between traffic visibility and the corresponding impact on device CPU load.

There are two primary factors that contribute to the CPU load increase from ACL logging: process switching of packets that match log-enabled access control entries (ACEs) and the generation and transmission of log messages.

Unfortunately, ACL logging can be CPU intensive and can negatively affect other functions of the network device. Logging-enabled access control lists (ACLs) provide insight into traffic as it traverses the network or is dropped by network devices.
