Chapter 9 VLAN

The following table describes the labels in this screen.

Table 21 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.
