9.11.1 C re a te a n IP- b a se d VLAN Exa m ple
This example shows you how to create an IP VLAN which includes ports 1, 4 and 8. Follow these steps:
1
Activate this protocol based VLAN.
2
Type the port number you want to include in this protocol based VLAN. Type
1
.
3
Give this protocol-based VLAN a descriptive name. Type
IP- VLAN
.
4
Select the protocol. Leave the default value
IP
.
5
Type the VLAN ID of an existing VLAN. In our example we already created a static VLAN with an ID of 5.
Type

label Description
Setting Wizard Choose
All c o nne c te d
or

.
All c o nne c te d
means all ports can communicate with each other, that is, there are no virtual
LANs. All incoming and outgoing ports are selected. This option is the most flexible but also the
least secure.
Po rt iso la tio n
means that each port can only communicate with the CPU management port and
cannot communicate with each other. All incoming ports are selected while only the CPU
outgoing port is selected. This option is the most limiting but also the most secure.
After you make your selection, click
Apply
(top right of screen) to display the screens as
mentioned above. You can still customize these settings by adding/deleting incoming or
outgoing ports, but you must also click
Apply
at the bottom of the screen.
Incoming These are the ingress ports; an ingress port is an incoming port, that is, a port through which a data
packet enters. If you wish to allow two subscriber ports to talk to each other, you must define the
ingress port for both ports. The numbers in the top row denote the incoming port for the
corresponding port listed on the left (its outgoing port).
C PU
refers to the Switch management
port. By default it forms a VLAN with all Ethernet ports. If it does not form a VLAN with a particular
port then the Switch cannot be managed from that port.
Outgoing These are the egress ports; an egress port is an outgoing port, that is, a port through which a data
packet leaves. If you wish to allow two subscriber ports to talk to each other, you must define the
egress port for both ports.
C PU
refers to the Switch management port. By default it forms a VLAN
with all Ethernet ports. If it does not form a VLAN with a particular port then the Switch cannot be
managed from that port.
Apply Click
Apply
to save your changes to the Switch’s run-time memory. The Switch loses these
changes if it is turned off or loses power, so use the
Sa ve
link on the top navigation panel to save
your changes to the non-volatile memory when you are done configuring.
