DESCRIPTION
Choose All connected or Port isolation.
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.
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.
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.
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.
Click Cancel to start configuring the screen again.
