Usage guidelines
This command enables the DHCP snooping device to generate DHCP snooping logs and send them
to the information center. For information about the log destination and output rule configuration in
the information center, see Network Management and Monitoring Configuration Guide.
As a best practice, disable this feature if the log generation affects the device performance.
