Configuring Ports for VLAN Membership

6–10
VLAN (Virtual Local Area Network) configuration is a technique for segmenting ports on an
Ethernet switch into logical groupings. Each logical grouping behaves as if it were a
separate physical LAN. A VLAN may also span multiple physical Ethernet switches through
the use of frame tagging. The Multinet4 supports VLAN as specified in IEEE 802.1Q (2003).
This appendix describes the VLAN implementation on the Multinet4.
Before you can use a VLAN you must explicitly add it to the switch configuration using the
form provided in the 4.4.4.2: VLAN: VIDs screen.

6.4.1.1 VLAN IDs

You can configure up to 16 VLANs, associating each with a VLAN ID (VID) in the range 1
through 4094 (the value 4095 is reserved), subject to the following limitations:
1. VID 1 is the default VLAN
2. VID 0 is defined as the NULL VID that is used in priority-tagged frames
Add a VLAN to the switch in the following steps:
Go to the 4.4.4.2: VLAN: VIDs screen.
Enter a valid VID and VLAN Name in the fields provided in the Add
VLAN form.
Click the Apply Settings button.
Each port to be included in a VLAN must be assigned a VID. They can also be configured to
expect tagged or untagged frames and filtered to include or exclude specific VLANs.

6.4.2.1 Port VLAN IDs

A Port VLAN ID (PVID) is a user-configurable parameter that associates a native VLAN with
a port. Each port is assigned exactly one PVID. By default, each port is assigned PVID 1.

6.4.2.2 Tagging

An Ethernet port in Multinet4 can be configured to expect tagged or untagged frames by
setting the "Tagged?" field appropriately in the 4.4.4.3: VLAN: Port Settings screen.
Tagged Field Set to No
When a port has its "Tagged?" field set to "No", that port will:
• Admit all untagged or priority-tagged frames and mark them with the port's PVID
• Admit tagged frames if and only if the tagged VID matches the port's PVID. All
other tagged frames will be dropped
