The following table describes the labels in this screen.
9.7 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.
Table 33 Advanced Application > VLAN > VLAN Port Setting > Protocol Based VLAN Setup
LABEL DESCRIPTION
Active Check this box to activate this protocol based VLAN.
Port Type a port to be included in this protocol based VLAN.
This port must belong to a static VLAN in order to participate in a protocol based VLAN. See
Chapter 9 on page 85 for more details on setting up VLANs.
Name Enter up to 32 alpha numeric characters to identify this protocol based VLAN.
Ethernet-type Use the drop down list box to select a predefined protocol to be included in this protocol based
VLAN or select Others and type the protocol number in hexadecimal notation. For example
the IP protocol in hexadecimal notation is 0800, and Novell IPX protocol is 8137.
Note: Protocols in the hexadecimal number range of 0x0000 to 0x05ff are not allowed to be
used for protocol based VLANs.
VID Enter the ID of a VLAN to which the port belongs. This must be an existing VLAN which you
defined in the Advanced Applications > VLAN screens.
Priority Select the priority level that the Switch will assign to frames belonging to this VLAN.
Add Click Add 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.
Cancel Click Cancel to begin configuring this screen afresh.
Index This is the index number identifying this protocol based VLAN. Click on any of these numbers
to edit an existing protocol based VLAN.
Active This field shows whether the protocol based VLAN is active or not.
Port This field shows which port belongs to this protocol based VLAN.
Name This field shows the name the protocol based VLAN.
Ethernet Type This field shows which Ethernet protocol is part of this protocol based VLAN.
VID This field shows the VLAN ID of the port.
Priority This field shows the priority which is assigned to frames belonging to this protocol based
VLAN.
Delete Click this to delete the protocol based VLANs which you marked for deletion.
Cancel Click Cancel to begin configuring this screen afresh.
