2.5. Divided LAN sharing one Internet connection
g1, g2, g7, g19, and g23 were clicked and then 12 entered in the Configured PVID field. The APPLY
button at the bottom of the screen was cliked to finish the configuration.
At this point the switch supported a single LAN in a signe VLAN. All devices could be pinged. If 192.
168.8.244 which was the modem on the wireless past of the network produced by 192.168.8.240
(port 23), and the url 192.168.8.244 was specified in the configuration of a device, then that device
could access the Internet.
Note:
• If the PVID part of the configuration is not down, then the apparently connected devices do not
ping;
• Gateway configuration is not part of the switch configuration.
2.4.2 Dividing the network into two parts
It may be desired for all devices be on the same network but to have some network devices isolated from
others. Figure ?? shows such a situation where all devices belong to the same 192.168.14.0 network.
The starting point was the single VLAN network configured above. The single VLAN is to be split into
two VLAN, the additional VLAN was to have ID 22 and name VLAN-B-22.
A new VLAN is created using the switch menu sequence:
Switching → VLAN → Basic → VLAN Configuration
resulted in the VLAN Configuration screen. Into the VLAN ID the value 22 was typed, then the value
VLAN-B-22 in the VLAN Name field before clicking the add button.
The switch menu sequence:
Switching → VLAN → Advnaced → VLAN Membership
was used to bring up the VLAN Membership screen. The value 12 was typed into the VLAN ID field.
The ports 19 and 23 were removed from this list and the APPLY button clicked. The value 22 was typed
into the VLAN ID field and ports 19 and 23 were added as untagged members before clicking the APPLY
field.
The switch menu sequence: Switching → VLAN → Advnaced → Port PVID Configuration
was used to bring up the Port PVID Configuration screen. The little square opposite the g19 and
g23 entries were clicked, the value 22 typed into the Configured PVID field, then the APPLY button
clicked.
With the two VLAN configuration completed, the two VLANs were tested. The devices on both VLANs
could be picged from devices in the VLAN, but not from the other VLAN. Now, only VLAN 22, which
contained the wireless network with it’s router could access the Internet.
2.5 Divided LAN sharing one Internet connection
The two VLAN network of Figure 2.3 was modified to that shown in Figure 2.4. In this configuration,
the two VLANs share the wireless network with its router allowing all members of each VLAN access
to the Internet.
The wireless extender connected to the switch at port was the be shared by VLANs 12 and 22. It was
already a member of VLAN 12. To added it to VLAN 12 the switch meenu sequence:
