To create an address pool:
Once an IP address is leased to a client, only that client may release the address. FTOS performs a IP + 
MAC source address validation to ensure that no client can release another clients address. This is a default 
behavior, and is separate from IP+MAC Source Address Validation on page 328.
Exclude Addresses from the Address Pool
The DHCP server assumes that all IP addresses in a DHCP address pool are available for assigning to 
DHCP clients. You must specify the IP address that the DHCP server should not assign to clients.
Specify an Address Lease Time
Specify a Default Gateway
The IP address of the default router should be on the same subnet as the client.
Step Task Command Syntax Command Mode
1 Access the DHCP server CLI context.

3 Specify the range of IP addresses from which the 
DHCP server may assign addresses.
• network is the subnet address.
• prefix-length specifies the number of bits 
used for the network portion of the address 
you specify.
network network /prefix-length
Prefix-length Range: 17-31
