Dimension ES-3024 Ethernet Switch
8-8 VLAN Setup
Table 8-4 Port-based VLAN Setup
FIELD DESCRIPTION
Preset Value Choose from Port Isolation, All Connected or Customized.
Port Isolation means that each port (1 to 26) 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.
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.
Select Customized to configure specific port-based VLANs (specific only to the ES-3024). Check
the ports that can communicate with each other. For two ports to communicate with each other,
you must define the incoming and outgoing port for both ports. For example, for (just) ports 3 and
5 to form a VLAN, select the ports as shown in Figure 8-4 Port-based VLAN Example.
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.

8.4.1 Port-based VLAN Example
First select Customized as the Preset Value and then select the ports as shown for ports 3 and 5 to be in the
same VLAN group.
