"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

This has the differences between etherchannel-vs-lacp-

 The limitation of one LAG per VDS is there, but there is no such limit on the Host. You can have multiple LAGs configured on a single Host by using multiple VDS. Here is further explanation

If you are using standard vSwitches, you have no choice, because LACP is not supported!

What physical switches do you have?

What do you want to accomplish ? and this is just VM Networking or iSCSI, vMotion ?

VLANs, TRUNKS ?

Resilience ?

Bandwidth ?

If you want to read more on networking in VMware ESX/ESXi, then I recommend the following:-

I would also recommend reading through the Networking Sections of the following guides to gain a better understanding of Networking in VMware ESX/ESXi.

Pages 13 - 73 Discuss Networking in Detail, including trunks, VLANs, switches, and load balancing

VMware vDS ?

What licenses do you have for VMware vSphere ?
IndyrbAuthor Commented:
yes vds and enterprise plus I can double check.
IndyrbAuthor Commented:
Is there a way to script the change of all vds port group or switches to change from ip hash to originating port id with LACP/LAGS
Andrew Hancock (VMware vExpert / EE MVE^2)VMware and Virtualization ConsultantCommented:
PowerCLI possibly, but I'm not certain that those parameters actually exist to change.
compdigit44Commented:
I thought when using LACP IP hash was the old recommended LB option

Also in regards to the difference between Etherchannel and LACP.. I believe Etherchannel is the name from bundling multiple ports together to form one link and LACP is he protocol used to auto configure both ends... Not and experts on this though
piedthepiperCommented:
I am sure they both do the same thing, except LAC is more automatic
