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.
