Ask your LAN switch vendor!
Most vendors support "short" if both NICs are connected to one LAN switch, but not if connected to two different LAN switches.
In the worst case a fail-over does not work. Do the "pull the cable" test at least!

Hi,
I need to setup a hacmp cluster (my first one, we usually use VCS on AIX), but I require more network bandwith than a normal gigabit etherchannel setup can provide, so I am thinking about using linkaggregation - 2 active adapters to one switch and a single backup adapter to another switch...

Hi,
I'm not from the Solaris world and some of these things are new to me. Can someone tell me if it is possible to configure link aggregation without using LACP?

VLAN(7) Miscellaneous Information Manual VLAN(7)
NAME
VLAN - virtual local area network
DESCRIPTION
This manpage provides a brief overview of VLAN (virtual LAN) technology.
VLANs are logical, or network segments that can span multiple physical network segments. A primary benefit of VLANs is that they can iso-
late 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 con-
nected 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 (see nwmgr_vlan(1M)) or (see lanadmin_vlan(1M)). HP recommends that
you use 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 and 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.
