LACP and AIX

[robertparsons]

I just configured 2 ports on 2 separate Nexus 3K using VPC and LACP and connected to an AIX box configured for 802.3ad and it is acting a bit strange.

If I bounce the port channels on each i see the MAC of the NIC's then a few seconds later they revert to 00.00.00.00.00.00. If I show port channel summary I see both Nexus with a status of (I)

I do not yet have an IP on the LACP bundle on the AIX box as it is a core production server but wanted to try to figure out this behavior before I try to utilize it.

Perhaps I need to change the channel group mode to ON instead of active?

Any ideas?

(i) is for individual (not bundled).  So you need to fix the Portchannel first.  It maybe a good idea to use mode ON as the server may not support LACP.

The AIX did show it would use LACP when 802.1ad was turn on. However this is setup as an access port and not trunk which I use on several other devices with no problem. Could that be an AIX problem? Maybe it wants to trunk only when using LACP?

I will try MODE ON tomorrow. and see what happens.

Thanks for the response.
