The Standard IP Access List Logging feature provides the ability to log messages about packets that are permitted or denied
by a standard IP access list. Any packet that matches the access list causes an information log message about the packet to
be sent to the device console. The log level of messages that are printed to the device console is controlled by the
logging console command.
The first packet that the access list inspects triggers the access list to log a message at the device console. Subsequent
packets are collected over 5-minute intervals before they are displayed or logged. Log messages include information about
the access list number, the source IP address of packets, the number of packets from the same source that were permitted or
denied in the previous 5-minute interval, and whether a packet was permitted or denied. You can also monitor the number of
packets that are permitted or denied by a particular access list, including the source address of each packet.
