Protocol-based VLAN Help

Help for Protocol-based VLAN Configuration

You can use a protocol-based VLAN to define filtering criteria for untagged packets. By default, if you do not configure any port- (IEEE 802.1Q) or protocol-based VLANs, untagged packets will be assigned to VLAN 1. You can override this behavior by defining either port-based VLANs or protocol-based VLANs, or both. Tagged packets are always handled according to the IEEE 802.1Q standard, and are not included in protocol-based VLANs.

If you assign a port to a protocol-based VLAN for a specific protocol, untagged frames received on that port for that protocol will be assigned the protocol-based VLAN ID. Untagged frames received on the port for other protocols will be assigned the Port VLAN ID - either the default PVID (1) or a PVID you have specifically assigned to the port using the Port VLAN Configuration screen.

You define a protocol-based VLAN by creating a group. Each group has a one-to-one relationship with a VLAN ID, can include one to three protocol definitions, and can include multiple ports. When you create a group you will choose a name and a Group ID will be assigned automatically.

Selection Criteria

• Group ID - You can use this screen to reconfigure or delete an existing protocol-based VLAN, or create a new one. Use this pulldown menu to select one of the existing PBVLANs, or select 'Create' to add a new one. A Group ID number will be assigned automatically when you create a new group. You can create up to 128 groups.

Configurable Data

• Group Name - Use this field to assign a name to a new group. You may enter up to 16 characters.
• Protocol(s) - Select the protocols you want to be associated with the group. There are three configurable protocols: IP, IPX, ARP. Hold down the control key to select more than one protocol.
  • IP - IP is a network layer protocol that provides a connectionless service for the delivery of data.
  • ARP - Address Resolution Protocol (ARP) is a low-level protocol that dynamically maps network layer addresses to physical medium access control (MAC) addresses
  • IPX - The Internetwork Packet Exchange (IPX) is a connectionless datagram Network-layer protocol that forwards data over a network.
• VLAN - VLAN can be any number in the range of (1 to 4041) . All the ports in the group will assign this VLAN ID to untagged packets received for the protocols you included in this group.
• Slot/Port(s) - Select the interface(s) you want to be included in the group. Note that a given interface can only belong to one group for a given protocol. If you have already added interface 0.1 to a group for IP, you cannot add it to another group that also includes IP, although you could add it to a new group for IPX.

Non-Configurable Data

• Group ID - A number used to identify the group created by the user. Group IDs are automatically assigned when a group is created by the user.

Command Buttons

• Submit - Update the switch with the values on this screen. If you want the switch to retain the new values across a power cycle, you must perform a save.
• Delete - Remove the Protocol Based VLAN group identified by the value in the Group ID field. If you want the switch to retain the deletion across a power cycle, you must perform a save.

Non-Configurable Data

• Group Name - The name associated with the group. Group names can be up to 16 characters long. The maximum number of groups allowed is 128.
• Group ID - The number used to identify the group. It was automatically assigned when you created the group.
• Protocol(s) - The protocol(s) that belongs to the group. There are three configurable protocols: IP, IPX, ARP.
  • IP - IP is a network layer protocol that provides a connectionless service for the delivery of data.
  • ARP - Address Resolution Protocol (ARP) is a low-level protocol that dynamically maps network layer addresses to physical medium access control (MAC) addresses
