The use of the 'log' keyword causes an informational logging message about the packet that matches the entry to be sent to the console. (The level of messages logged to the console is controlled by the 'logging console' command.)
The message includes the access list number, whether the packet was permitted or denied, the source address, and the number of packets. The message is generated for the first packet that matches, and then at 5-minute intervals, including the number of packets permitted or denied in the prior 5-minute interval.
The 'logging console [severity-level]' command determines the nature of the messages logged to the console. The severity levels available are:
By default, all levels up to level 7 (debugging) are sent to the console. So, for example, if you configure 'logging console 6', debug messages will not be displayed (only level 0-6 will be displayed).
For your ACL logging, you need to use a level of 6 or 7, otherwise no information is logged or displayed.
Therefore, if you are using defaults, you should be fine and will see the ACL logging messages.
