86 Chapter 8 VLAN
8.6 Port-based VLANs
Port-based VLANs are VLANs where the packet forwarding decision is based on the
destination MAC address and its associated port.
Port-based VLANs require allowed outgoing ports to be defined for each port. Therefore, if
you wish to allow two subscriber ports to talk to each other, for example, between conference
rooms in a hotel, you must define the egress (an egress port is an outgoing port, that is, a port
through which a data packet leaves) for both ports.
Port-based VLANs are specific only to the switch on which they were created.
Note: When you activate port-based VLAN, the ES-4024A uses a default VLAN ID of
1. You cannot change it.
In screens (such as IP Setup and Filtering) that require a VID, you must enter
1 as the VID.
The port-based VLAN setup screen is shown next. The CPU management port forms a VLAN
with all Ethernet ports.
8.6.1 Configure a Port-based VLAN
Select Port Based as the VLAN Type in the Switch Setup screen (see Figure 35 on page 82)
and then click VLAN from the navigation panel to display the next screen.
PVID Enter a number between 1and 4094 as the port VLAN ID.
GVRP Select this check box to allow GVRP on this port.
Acceptable Frame
Type
Specify the type of frames allowed on a port. Choices are All, Tag Only and Untag
Only.
Select All from the drop-down list box to accept all untagged or tagged frames on
this port. This is the default setting.
Select Tag Only to accept only tagged frames on this port. All untagged frames will
be dropped.
Select Untag Only to accept only untagged frames on this port. All tagged frames
will be dropped.
VLAN Trunking Enable VLAN Trunking on ports connected to other switches or routers (but not
ports directly connected to end users) to allow frames belonging to unknown VLAN
groups to pass through the switch.
