• Address Pool End—Enter the last IP address in the range of the network pool.
• Lease Duration—Enter the amount of time a DHCP client can use an IP address from
this pool. You can configure a lease duration of up to 49,710 days or an infinite duration.
- Infinite—The duration of the lease is unlimited.
- Days—The duration of the lease in number of days. The range is 0 to 49710 days.
- Hours—The number of hours in the lease. A days value must be supplied before an
hours value can be added.
- Minutes—The number of minutes in the lease. A days value and an hours value must
be added before a minutes value can be added.
• Default Router IP Address (Option 3)— Enter the default router for the DHCP client.
• Domain Name Server IP Address (Option 6)—Select one of the devices DNS servers
(if already configured) or select Other and enter the IP address of the DNS server
available to the DHCP client.
• Domain Name (Option 15)—Enter the domain name for a DHCP client.
• NetBIOS WINS Server IP Address (Option 44)— Enter the NetBIOS WINS name
server available to a DHCP client.
• NetBIOS Node Type (Option 46)—Select how to resolve the NetBIOS name. Valid
node types are:
- Hybrid—A hybrid combination of b-node and p-node is used. When configured to
use h-node, a computer always tries p-node first and uses b-node only if p-node
fails. This is the default.
- Mixed—A combination of b-node and p-node communications is used to register
and resolve NetBIOS names. M-node first uses b-node; then, if necessary, p-node.
M-node is typically not the best choice for larger networks because its preference
for b-node Broadcasts increases network traffic.
- Peer-to-Peer—Point-to-point communications with a NetBIOS name server are
used to register and resolve computer names to IP addresses.
- Broadcast—IP Broadcast messages are used to register and resolve NetBIOS names
to IP addresses.
• SNTP Server IP Address (Option 4)— Select one of the device’s SNTP servers (if
already configured) or select Other and enter the IP address of the time server for the
DHCP client.
