It is possible to add a user-defined option with the same number as an existing pre-
defined option. If this situation occurs, the user-defined option takes precedence—that is,

To set a subnet mask (option 1) for the address pool, use the command:
To add a domain name (option 15) for the address pool, use the command:
To add a default router (option 3) for the address pool, use the command:
To add a DNS server (option 6) for the address pool, use the command:
awplus# configure terminal

name>] [<option-type>]
awplus(config)# ip dhcp pool <pool-name>
awplus(dhcp-config)# option [<1-254>|<option-name>]
