To be honest i don't know your cards and will probably not be of much help to you. Just a few things here i can clear up:

"Etherchannel" is IBMs name for bundling several IP interfaces together to one. You can do that either for failover purposes or for load balancing. The process is: you first create the physical interfaces (entX, entX+1, ...), don't give them any IP address or configure them otherwise, then create an "Etherchannel" device from them. You probably want to follow the SMIT panels for this, they are pretty self-explanatory.

Issue a

Code:
lsdev -Cc adapters

which should show you your cards as well as by which device name they go by.

I hope this helps.

If you have two or more servers load balancing, are the servers mirroring one another? If images, etc., are uploaded, will they be stored on all the servers so that if one server goes down, the images will be served up by another server? (1 Reply)

ipsec_tncfg

IPSEC_TNCFG(8)							  [FIXME: manual]						    IPSEC_TNCFG(8)

NAME

       ipsec_tncfg - manipulate KLIPS virtual interfaces

SYNOPSIS

       ipsec tncfg
	     ipsec tncfg --create virtual
	     ipsec tncfg --delete virtual
	     ipsec tncfg --attach --virtual virtual --physical physical
	     ipsec tncfg --detach --virtual virtual
	     ipsec tncfg --clear
	     ipsec tncfg --version
	     ipsec tncfg --help

OBSOLETE

       Note that tncfg is only supported on the classic KLIPS stack. It is not supported on any other stack and will be completely removed in
       future versions. A replacement command still needs to be designed

DESCRIPTION

       The historical use of tncfg is to attach/detach IPsec virtual interfaces (e.g. ipsec0) to/from physical interfaces (e.g. eth0) through
       which packets will be forwarded once processed by KLIPS.

       The modern use of tncfg is to create and delete virtual interfaces known as mastXXX. mast stands for Mooring and XXX.

       The form with no additional arguments lists the contents of /proc/net/ipsec_tncfg. The format of /proc/net/ipsec_tncfg is discussed in
       ipsec_tncfg(5).

       The --attach form attaches the virtual interface to the physical one.

       The --detach form detaches the virtual interface from whichever physical interface it is attached to.

       The --clear form clears all the virtual interfaces from whichever physical interfaces they were attached to.

       Virtual interfaces typically have names like ipsec0 or mast0 while physical interfaces typically have names like eth0 or ppp0.

EXAMPLES

       ipsec tncfg --create mast12
	   creates the mast12 device.

       ipsec tncfg --create ipsec4
	   creates an ipsec4 device, but does not attach it.

       ipsec tncfg --attach --virtual ipsec0 --physical eth0
	   attaches the ipsec0 virtual device to the eth0 physical device.

FILES

       /proc/net/ipsec_tncfg, /usr/local/bin/ipsec
