Managing a Switch
Over the Network
When managing a Switch over the network, the Switch must be correctly
configured with the following IP information:
■
An IP address — for more information, see “IP Addresses” on
page 38
.
■
A subnet mask — for more information, see “Subnets and Using a
Subnet Mask” on page 39.
IP Addresses
If you are uncertain about what IP addresses to assign your equipment,
contact your network administrator.
To operate correctly, each device on your network (for example a hub or
management station) must have a unique IP address (if one is
configured). IP addresses have the format
n.n.n.n
where
n
is a decimal
number between 0 and 255. An example IP address is ‘192.168.100.8’.
The IP address can be split into two parts:
■
The first part (‘192.168’ in the example) identifies the network on
which the device resides.
■
The second part (‘100.8’ in the example) identifies the device within
the network.
If your network is internal to your organization only, you may use any
arbitrary IP address. We suggest you use addresses in the series
192.168.100.
X
(where
X
is a number between 1 and 254) with a subnet
mask 255.255.255.0. Use the default SLIP address of 192.168.101.1 with
a subnet mask of 255.255.255.0.
These suggested IP addresses are part of a group of IP addresses that have
been set aside specially for use “in house” only.
CAUTION:
If your network has a connection to the external IP network, you
must apply for a registered IP address. This system ensures that every IP
address used is unique; if you do not have a registered IP address, you may
be using an identical address to someone else and your network will not
operate correctly.
Obtaining a Registered IP Address
InterNIC Registration Services is the organization responsible for
supplying registered IP addresses. The following contact information is
