Domain Name
While leasing an IP address to a client, the domain name configuration information is also available
from the Hypertec Router DHCP server.
Lease Duration
The lease duration describes the maximum time length the IP address is leased to a client. A client
usually renews the IP address half way before the lease duration expired.
The maximum lease duration is 100 days. The minimum lease duration is 1 day even if a duration of
less than one day is entered. Note that when NMS modifies the DHCP lease duration, the lease
duration associated with a leased IP address remains unchanged until expired.
Active Lease(s)
This number indicates how many IP addresses have been leased to clients.
Lease Table Entry
Each table entry describes to whom the IP address was leased and for how long.
DHCP Enable
The check box lets the user dynamically enable or disable the DHCP function. Note that if all stations
including the NMS manager depend on Hypertec Router for assigning IP addresses, and the NMS
manager disables the Hypertec Router DHCP function. Under that circumstance, the NMS may not be able
to communicate with the Hypertec Router if DHCP service is not re-enabled before the lease duration has
expired.
