interfaces must acquire their IP addresses from the same server a bridge should 
be created, and those interfaces should be added under that bridge. Then, select 
that bridge as the DHCP server interface. 
NOTE: You cannot select an interface which is under a bridge as the DHCP server
interface. Additionally the DHCP server interface should have already been configured with 
a valid IP address and subnet mask. Multiple DHCP servers on different interfaces are
allowed.
7.1.1.
Setting DHCP Server Fields
To configure DHCP server settings, select the Server  option button and select 
the Active check box. The Server  tab becomes available. After completing the 
required fields, click the Submit  buttonThis uploads the configuration to the 
node without starting the server. 
Start IP and End IP 
Type the appropriate IP addresses into the Start IP and End IP fields. These 
are the upper and lower limits for the DHCP server address pool. 
Broadcast 
Type the appropriate IP address into the Broadcast field. This field contains the 
IP address clients will use. Broadcast IP should be one of the addresses the 
Subnet Mask permits. 
Subnet Mask 
Type the appropriate IP address into the Subnet Mask field. This is the subnet 
mask clients will use. 
Domain
Type the Domain  name (if any) that will be allocated to clients into this text 
box.
Time Parameters 
For each of the following fields, type the appropriate value into the box. 
Lease 
The Lease  field contains the number of seconds an allocated IP is valid. After 
expiration the client has to renegotiate for getting a new IP (which is usually the 
same). The expiration time that the client adopts depends on the operating 
system running on the client and the DHCP client configuration. 
Decline
The  Decline  field contains the number of seconds that an IP will be reserved 
(leased) for if a DHCP decline message is received. 
Min Lease 
The Min Lease field contains the minimum number of seconds. If a lease to be 
given is below this value (sec), the full lease time is used instead. 
Conflict 
The  Conflict  field contains the amount of time (sec) that an IP address will be 
reserved (leased) if an ARP conflict (two clients with the same IP address) 
occurs.
