DHCP lease time
The DHCP standard states that when a DHCP lease expires, the device should immediately
cease using its assigned IP address. However, if the network has problems and the only DHCP
server is centralized or if the DHCP server itself has problems, the device will not receive
responses to its request for a renewal of the lease. In this case the device is not usable until the
server can respond. Configure system such that once the IP address is assigned to the device,
the device continues using that address after the DHCP lease expires, until a conflict with another
device is detected.
The system parameter DHCPSTD allows an administrator to specify that the device will either:
• Comply with the DHCP standard by setting DHCPSTD to 1.
• Continue to use its IP address after the DHCP lease expires by setting DHCPSTD to 0.
