NAME
VLAN - virtual local area network
DESCRIPTION
This manpage provides a brief overview of VLAN (virtual LAN) technology.
VLANs are logical, or virtual, network segments that can span multiple physical network segments. A
primary benefit of VLANs is that they can isolate broadcast and multicast traffic by determining which
destinations should receive that traffic, thereby making better use of switch and end-station resources.
Logical separation using VLAN allows for the logical grouping of PCs, servers and other network
resources to behave as if they were connected to the same, physical segment, even if they are not.
HP-UX VLAN is an implementation of IEEE 802.1p/Q standards.
VLAN interfaces can be configured in HP-UX servers using the command
nwmgr (see nwmgr_vlan (1M))
or
lanadmin (see lanadmin_vlan(1M)). HP recommends that you use
nwmgr for HP-UX Release 11i
Version 3 and forward. Interfaces can also be configured using the web-based management tool HP-UX
System Management Homepage (HP SMH).
Each VLAN interface created is assigned a VLAN PPA (VPPA) that is unique across the system and a
VLAN ID, that identifies the virtual LAN it is part of. The VLAN ID is unique on the interface on which
the VLAN interface is created.
WARNINGS
The
lanadmin, lanscan, and linkloop commands are deprecated. These commands will be
removed in a future HP-UX release. HP recommends the use of replacement command nwmgr(1M) to
perform all network interface-related tasks.
