Chapter 9 VLAN The following table describes the labels in this screen. Table 23 Port Based VLAN Setup label Description Setting Wizard Choose All connected or Port isolation. All connected 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. Port isolation 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. Incoming Outgoing Apply Cancel 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. 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). CPU 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. 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. CPU 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. 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 Save link on the top navigation panel to save your changes to the non-volatile memory when you are done configuring. Click Cancel to begin configuring this screen afresh. 9.8 Technical Reference This section provides technical background information on the topics discussed in this chapter. 9.8.1 Create an IP-based VLAN Example 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 5.

9.8.1
Create an IP-based VLAN Example
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
.

Type the VLAN ID of an existing VLAN. In our example we already created a static VLAN with an ID
of 5. Type
5
.

Description
Setting Wizard
Choose
All connected
or
Port isolation
.
All connected
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.
Port isolation
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).
CPU
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.
CPU
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
Save
link on the top navigation panel to
save your changes to the non-volatile memory when you are done configuring.
