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

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

After you make your selection, click Apply (top right of screen) to display the screens as

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.

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.
