Configuring 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. For information about the log destination and output rule configuration in the
information center, see Network Management and Monitoring Configuration Guide.
Disable this feature when 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.
To configure DHCP logging on the DHCP server:
Step Command Remarks
1. Enter system view.
system-view
N/A
2. Enable DHCP logging.
dhcp log enable
By default, DHCP logging is disabled.
Displaying and maintaining the DHCP server
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.
