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 Set (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. |
