Dimension ES-3124 Ethernet Switch
VLAN 7-13
Table 7-6 Port Based VLAN Setup
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 ( Figure 7-8 ). 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 (
Figure 7-9 ). 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.
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.
