Configuring Packet Filtering Statistics Function

The Switch 4210G series switches provide the packet filtering statistics function so that the device can
output packet filtering statistics information at a specified interval. With the output, you are able to
know how many packets are filtered by which ACL rules.
The packet filtering statistics function takes effect for only rules with the logging keyword specified.
The packet filtering statistics are managed and output as device log information by the information
center.
The packet filtering statistics are of the severity level of 6, that is, informational. Informational
messages are not output to the console by default; therefore, you need to modify the log
information output rule for the informational message output to be sent to the console or other
destinations.
For introduction and configuration of the information center, refer to Information Center
Configuration in the System Volume.
Follow the steps to set the intervals for packet filtering statistics so that the device outputs packet
filtering statistics at the end of every interval:
