removes the connection. Once the connection type is selected, the
Apply
button in the bottom right
hand corner of the screen is clicked to have the switch perform the change.
The port to VLAN connection types are:
T
trunk
carrying traffic for more than one VLAN
U
untagged
blank
not connected
When a port box is shown as
blank
, the device connected to that port is no longer accessible from other
devices on the VLAN having the same network address.

Initial switch configuration
Default address of the switch was
192.168.0.239
and default switch gateway address
192.168.0.
254
. These defaults were changed by logging into the switch using a PC whose ethernet address is
192.168.0.x
where x is a value in the range 1 to 253, excluding 239 (which would give a conflict with
the default network address of the switch). The value of x chosen was 7. This PC was connected to the
switch via any of the RJ45 ethernet ports on the switch. Putting the address
192.168.0.239
into the
address field of a web broswer running on the PC opened the login page of the switch. Using the default
password
password
enabled logging into the switch and enabling the PC’s web browser to be used to
set up the switch.
The address of the switch is required to configure the switch. It is a good idea to have the switch address
laying on one of the LANs the switch is handling. To change the switch address, log into the switch, and
then use the switch command sequence
System
>
Management
>
IP Configuration
to bring up the page containing the current network settings of the switch. It is a good idea to have the
switch of a fixed address. So set the
Current Network Configuration Protocol
radio button
Static IP Address
to on. Then assigned an address to the switch by changing the
IP Address
field on the page to contain that selection. Then press the
Apply
button in the bottom right of the
command screen.
The switch address should not be on a VLAN to be handled by the switch. This is particularly true if
VLANs are to be routed. The address
192.168.10.60
and default gateway
192.168.10.244
were
assigned to the switch for this work.

Gateway from a simple network on the switch
A LAN was created by plugging network components into the switch. This LAN is shown in Figure 1.2
as containing a PC and a wireless extenter which were physically plugged into the switch. The switch
thus became an active part of the LAN. The LAN required a gateway to access the Internet and this
was to be provided by the wireless extender which had been configured to route any data sent to it out
onto the wireless network. Without changing the addresses of the LAN devices, the gateway was to be
produced.
