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).
