Types of VLANs Supported by HP-UX

The types of HP-UX VLANs that you can create are as follows:

• NIC-Port Based--A group of physical LAN card ports belong to the

same layer-2 broadcast domain. Each LAN card port transmits and

receives frames belonging to the VLAN associated with that port.

Members of the same port-based VLAN all have the same VLAN ID.

A VLAN ID uniquely identiﬁes the VLAN to which a frame belongs.

• Protocol Based--Common protocols such as IP, IPX, AppleTalk,

Decnet, and NetBIOS are grouped into layer-2 broadcast domains.

• IP Subnet Based--Each IP subnet has its own unique VLAN. Trafﬁc

from different subnets is logically separated from each other as if

each subnet were on a different LAN segment.

Please refer to “Planning HP-UX VLANs” in this document for more

information on setting up the different types of VLANs described.

HP-UX VLANs conform to IEEE speciﬁcations 802.1Q (for VLAN

tagging) and IEEE 802.1p (MAC-level frame prioritizing) to provide

end-to-end class of service (CoS).
