Parameters
code: Customized option number ranging from 2 to 254. Note that this argument cannot be 3, 6, 15, 44,
46, 50 through 55, 57 through 61, 66, 67, 82, 150, 184, or 217.

addresses. When inputting more than one IP address, separate two neighboring IP addresses with a
space.
interface interface-type interface-number [ to interface-type interface-number ]: Specifies the
interface(s), through which you can specify the corresponding DHCP interface address pools. The
interface-type argument specifies an interface type; the interface-number argument specifies an
interface number; the interface interface-type interface-number [ to interface-type interface-number ]
keyword and argument combination specifies an interface range.
all: Specifies all interface address pools.
