Re: Aggregate Ethernet Lines

[DrFranken <midrange@xxxxxxxxxxxx>]

EtherChannel and LACP (Link Aggregation Control Protocol) are two 
different things. They are in fact very close but not the same. 
EtherChannel is a Cisco name that they invented which has been 
implemented by some other vendors. LACP is a formal specification used 
by many vendors.

Etherchannel is supported in IBM i 7.1 TR3 and above. LACP support came 
in TR7 as I recall. i 7.2 and 7.3 have both in the base.

If your switches support it I would use LACP.

In the *LIND once you enter *AGG for the resource name you must select 
from *LNKAGG or *ETHCHL depending on how the switches are configured.

Using CISCO equipment has worked with the shops I have installed it with, but then one time we tried it with some network switch vendor I never heard of and they had to do a few different configurations on the switch before I got it to work

> Last November we installed a new Power8 server and are running V7.1. We have two 4 port NICs with only three ports on one NIC being used. When we did the install we didn't have a network switch that could be configured for automatic failover so we didn't configure the iSeries for aggregation. Now we do have an upgraded switch and can do the setup.  We have never done this before. I found this document  http://www.ibm.com/developerworks/ibmi/library/i-ethernetlines/ for configuring the NIC side. It does not talk at all about changes to the switch side. Has anyone done this kind of setup and come across any issues ?
