The following table describes the fields in the above screen.
57.15 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 SYSTEM > IP Setup and SWITCHING > Static MAC 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.

LABEL DESCRIPTION
Name Enter a name up to 32 alphanumeric characters except [ ? ], [ | ], [ ' ], or [ " ] for the vendor
ID based VLAN entry.
MAC Address Enter a MAC address that is bind to the vendor ID-based VLAN entry. This is the source MAC
address of the data packet that is looked up when untagged packets arrive at the Switch.
Mask Enter the mask for the specified source MAC address to determine which bits a packet’s
MAC address should match.
Enter “f” for each bit of the specified MAC address that the traffic’s MAC address should
match. Enter “0” for the bits of the matched traffic’s MAC address, which can be of any
hexadecimal characters. For example, if you set the MAC address to 00:13:49:00:00:00 and
the mask to ff:ff:ff:00:00:00, a packet with a MAC address of 00:13:49:12:34:56 matches this
criteria.
VID Enter an ID (from 1 to 4094) for the VLAN that is associated with the vendor ID based VLAN
entry.
Priority Select the priority level that the Switch assigns to frames belonging to this VLAN. The higher
the numeric value you assign, the higher the priority for this vendor ID based VLAN entry.
Weight Enter a number between 0 and 255 to specify the rule’s weight. This is to decide the priority
in which the rule is applied. The higher the number, the higher the rule’s priority.
Apply Click Apply to save your changes to the Switch’s run-time memory. The Switch loses these
changes if it is turned off or loses power, so use the Save link on the top navigation panel to
save your changes to the non-volatile memory when you are done configuring.
Clear Click Clear to clear the fields to the factory defaults.
Cancel Click Cancel to not save the configuration you make and return to the last screen.
