day day: Specifies the number of days, in the range of 0 to 365.
hour hour: Specifies the number of hours, in the range of 0 to 23.
minute minute: Specifies the number of minutes, in the range of 0 to 59.
second second: Specifies the number of seconds, in the range of 0 to 59.
unlimited: Specifies the unlimited lease duration, which is actually 136 years.
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
# Specify the lease duration as 1 day, 2 hours, 3 minutes, and 4 seconds in DHCP address pool 0.
