Pinned topic Clarifying switch side requirements for link aggregation

‏2012-10-02T17:48:36Z |
Hi all. Getting some mixed signals from my googly searches here. Can someone confirm for me whether the following is correct or not:

When creating an 802.3ad (8023ad) link aggregation device, it is not necessary for any switch side configuration to be done. This is in contrast to an EtherChannel (standard) link aggregation device which requires configuration of the ports involved in the EtherChannel.

Also, assuming the above is correct, is it possible to simply reconfigure an existing standard (EtherChannel) lnagg device as an 802.3ad device? Or does the device need to be removed and recreated?

Thanks,
Mark

    I would think the need for switch side configuration would depend on the switch. Using the below Red Book (page 68) as an example of how to configure a Blade switch for LA, it appears there is a global enable need as well as some port related configuration, but this is only for that switch.
