The following table describes the labels in this screen.
Table 47 Configuration: VLAN Configuration: Port Based
LABEL DESCRIPTION
Setting Wizard Choose from 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 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.
