Get IP From
There are three choices for how the switch receives its IP Address settings:
Manual, BOOTP, and DHCP.
Manual
You can enter an IP address, a subnet mask, and a default
gateway for the switch. These fields should be of the form
xxx.xxx.xxx.xxx, where each xxx is a number (represented in
decimal form) between 0 and 255. This address should be a unique
address on the network assigned for use by the network
administrator. The fields that require entries under this option are as
follows:
IP Address
Subnet Mask
Default Gateway
BOOTP
The switch module will send out a BOOTP broadcast request when
it is turned on. The BOOTP protocol enables IP addresses, network
masks, and default gateways to be assigned by a central BOOTP
server. If this option is set, the switch module will first look for a
BOOTP server to provide it with this information before using the
default or previously entered settings.
DCHP The switch module will send out a DCHP broadcast request when it
is turned on. The DCHP protocol enables IP addresses, network
masks, and default gateways to be assigned by a DCHP server. If
this option is set, the switch will first look for a DCHP server to
provide it with this information before using the default or previously
entered settings.
The host address for the device on the TCP/IP network.
The address mask that controls subnetting on your TCP/IP
network. This address mask is a bitmask that determines
the extent of the subnet that the switch module is on.
Should be of the form xxx.xxx.xxx.xxx, where each xxx is a
number (represented in decimal) between 0 and 255. The
value should be 255.0.0.0 for a Class A network,
255.255.0.0 for a Class B network, and 255.255.255.0 for a
Class C network, but you can also use custom subnet
masks.
Note: For switch communication with a remote
management station, such as the IBM Director
server, through the management module external
Ethernet port, the switch module internal network
interface and the management module internal and
external interfaces must be on the same subnet.
The IP address that determines where packets with a
destination address outside the current subnet should be
sent. The IP address of the device is usually the address of
a router or a host acting as an IP gateway to handle
connections to other subnets or other TCP/IP networks. If
your network is not part of an intranet, or you do not want
the device to be accessible outside your local network, you
can enter a value of 0.0.0.0 in this field.
