P FOR ANAGEMENT
To manage a Switch over the network, the Switch must be correctly
configured with the following IP information:
An IP address — for more information, see
A subnet mask — for more information, see
Subnet Mask"
A default IP router — if you do not know what your default IP router
address is, contact your network administrator.
If you are uncertain about what IP addresses to assign to 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. 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.
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 registration 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.
