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 |
| 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. |
