The following table describes the labels in this screen.
Table 213 SWITCHING > VLAN > Port Based VLAN Setup
LABEL DESCRIPTION
Setting Wizard Choose Current configuration to display the Switch’s current port-based VLAN configuration.
Choose All connected or Port isolation wizard to quickly set up a port-based VLAN according to
the below descriptions.
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 selecting the setting wizard, you can customize the port settings. Click on the ports to add or
delete incoming or outgoing ports. The configuration will be saved only after you 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.
