Usage guidelines
The DHCP server assigns an IP address together with the lease duration to the DHCP client. Before
the lease expires, the DHCP client must extend the lease duration.
•
If the lease extension operation succeeds, the DHCP client can continue to use the IP address.
•
If the lease extension operation does not succeed, both of the following events occur:

The DHCP client cannot use the IP address after the lease duration expires.

The DHCP server will label the IP address as an expired address.
Examples
# Set the lease duration to 1 day, 2 hours, 3 minutes, and 4 seconds in DHCP address pool 0.
