Enabling DHCP logging on the DHCP server
About DHCP logging on the DHCP server
The DHCP logging feature enables the DHCP server to generate DHCP logs and send them to the
information center. The information helps administrators locate and solve problems. For information
about the log destination and output rule configuration in the information center, see Network
Management and Monitoring Configuration Guide.
Restrictions and guidelines
As a best practice, disable this feature if the log generation affects the device performance or
reduces the address allocation efficiency. For example, this situation might occur when a large
number of clients frequently come online or go offline.
Procedure
1. Enter system view.

IMPORTANT:
A restart of the DHCP server or execution of the
reset dhcp server ip-in-use command
deletes all lease information. The DHCP server denies any DHCP request for lease extension, and
the client must request an IP address again.
Execute display commands in any view and reset commands in user view.
