The “/” (forward slash) is a parameter delimiter that separates the ip-address portion of the IP
address from the mask, which defines the scope of the local subnet. No spaces are allowed
between the ip-address, the “/”, and the mask. If a forward slash does not immediately follow the
ip-address, a dotted-decimal mask must follow the prefix.
mask — the subnet mask length when the IP prefix is specified in CIDR notation. When the IP prefix
is specified in CIDR notation, a forward slash separates the ip-address from the mask. The mask
indicates the number of bits used for the network portion of the IP address; the remainder of the
IP address is used to determine the host portion of the IP address.
Values 0 to 32
netmask — the subnet mask, in dotted-decimal notation. When the IP prefix is not specified in CIDR
notation, a space separates the ip-address from a traditional dotted-decimal mask. The netmask
parameter indicates the complete mask that will be used in a logical ‘AND’ function to derive the
local subnet of the IP address.
Values 128.0.0.0 to 255.255.255.252
(network bits all 1 and host bits all 0)
(255.255.255.255 is reserved for system IP addresses)
broadcast — the optional broadcast parameter overrides the default broadcast address used by the
IP interface when sourcing IP broadcasts on the IP interface. If no broadcast format is specified
for the IP address, the default value is host-ones, which indicates a subnet broadcast address. Use
this parameter to change the broadcast address to all-ones or revert back to a broadcast address of
host-ones.
The broadcast format on an IP interface can be specified when the IP address is assigned or
changed.
This parameter does not affect the type of broadcasts that can be received by the IP interface. A
host sending either the local broadcast (all-ones) or the valid subnet broadcast address (host-
ones) will be received by the IP interface.
Default host-ones
all-ones — specifies that the broadcast address used by the IP interface for this IP address will be
255.255.255.255, also known as the local broadcast
host-ones — specifies that the broadcast address used by the IP interface for this IP address will be
the subnet broadcast address. This is an IP address that corresponds to the local subnet described
by the ip-address and the mask, or the mask with all the host bits set to binary one. This is the
default broadcast address used by an IP interface.
The broadcast parameter within the address command does not have a negation feature, which
is usually used to revert a parameter to the default value. To change the broadcast type to host-
ones
after being changed to a
ll-ones, the address command must be executed with the broadcast
parameter defined.
