average-ip-use threshold-value: Enables the DHCP server to send trap messages to the network
management server when the average IP address utilization of an address pool within 5 minutes reaches
the threshold specified by the threshold-value argument. The threshold is a percentage value in the range
of 1 to 100.
max-ip-use threshold-value: Enables the DHCP server to send trap messages to the network management
server when the maximum IP address utilization of an address pool within 5 minutes reaches the
threshold specified by the threshold-value argument. The threshold is a percentage value in the range of
1 to 100.
