We are currently working in a lab to configure our first pair of 5548UP(with a 2232PP on each) with FCoE to an IBM p740 AIX server. On the Nexus side I have confugured the physical port e100/1/1 (2232pp) to be in a channel-group that will be part of a vpc with the other 5548UP switch, I am trunking all vlans in the etherchannel with the IBM server. Everything is working, i have the port-channel UP, the vfc and vpc when I use ''channel-group x mode ON'' on the physical ports and on the server side the 803.2ad is not active, it's configured ''roundRobin''.
Suppose I want to use LACP for the connections with the server should I configure the Nexus switch port with ''channel-group x mode active'' or ''channel-group x mode passive''? When the server is configured with ''802.3ad'' enabled and when I have ''channel-group x mode active'' or ''passive'' it doesn't work, the port-channel x does not come UP.
Does anyone have an explenation of how I should be configure?
