Configuring SNMP notifications for the DHCP
server
Perform this task to configure the DHCP module to send SNMP notifications to report the following
DHCP server events:
•
Exhaustion or recovery of a DHCP address pool.
•
Usage threshold violation in a DHCP address pool.
•
IP address allocation success rate threshold violation.
The SNMP notifications are sent to the SNMP module. For the SNMP notifications to be sent
correctly, you must also configure SNMP. For more information about SNMP configuration, see
Network Management and Monitoring Configuration Guide
.
For a DHCP address pool usage threshold violation, the DHCP module also sends a log message to
the information center. For log messages to be sent correctly, you must also configure the
information center. For information about the information center configuration, see
Network
Management and Monitoring Configuration Guide
.
