Chapter 9 VLAN

The following table describes the labels in this screen.

Table 22 Advanced Application > VLAN: Port Based VLAN Setup

LABEL

DESCRIPTION

Setting

Choose All connected or Port isolation.

Wizard

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.

 

 

Cancel

Click Cancel to begin configuring this screen afresh.
