9.11 Port-based VLAN Setup
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 Switch uses a default VLAN ID of 1.
You cannot change it.
Note: 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.
9.11.1 Configure a Port-based VLAN
Select
Port Based
as the VLAN Type in the Switch Setup screen and then click
VLAN from the navigation panel to display the following screen. Select either All
Connected or Port Isolated from the drop-down list depending on your VLAN
and VLAN security requirements. If VLAN members need to communicate directly
with each other, then select All Connected. Select Port Isolated if you want to
restrict users from communicating directly. Click Apply to save your settings.
