Link Aggregation and LACP
Hi there
I have a requirement to provide failover to our customer boxes in case of interface / switch failure, I have been looking at Solaris Link Aggregation with LACP and I wanted to ask a question
Ive seen multiple websites that say the following
Quote:
You cannot use link aggregation if you are using two separate switches. As per IEEE 802.3ad, an aggregation connects two end-points. Some switch vendors implement their own extensions which allows a single "logical" aggregation to span multiple switches, but these solutions are not yet common and don't always explicitly
support 802.3ad.
Does this also mean that if the switches are
trunked together that you still cant use 2 switches ??. One absolute requirement of this project is that I use 2 seperate switches, so if this isnt possible, then Ill have to look into IPMP or something else
Any help would be greatly appreciated

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...

IBCACHEEDIT(8) Open IB Diagnostics IBCACHEEDIT(8)
NAME
IBCACHEEDIT -
edit an ibnetdiscover cache
SYNOPSIS
ibcacheedit [options] <orig.cache> <new.cache>
DESCRIPTION
ibcacheedit allows users to edit an ibnetdiscover cache created through the --cache option in ibnetdiscover(8) .
OPTIONS
--switchguid BEFOREGUID:AFTERGUID
Specify a switchguid that should be changed. The before and after guid should be separated by a colon. On switches, port guids are
identical to the switch guid, so port guids will be adjusted as well on switches.
--caguid BEFOREGUID:AFTERGUID
Specify a caguid that should be changed. The before and after guid should be separated by a colon.
--sysimgguid BEFOREGUID:AFTERGUID
Specify a sysimgguid that should be changed. The before and after guid should be spearated by a colon.
--portguid NODEGUID:BEFOREGUID:AFTERGUID
Specify a portguid that should be changed. The nodeguid of the port (e.g. switchguid or caguid) should be specified first, followed
by a colon, the before port guid, another colon, then the after port guid. On switches, port guids are identical to the switch
guid, so the switch guid will be adjusted as well on switches.
