Link Aggregate Group (LAG.) A LAG cannot span multiple Virtual Connect modules

 Link Aggregate Group (LAG.) A LAG cannot span multiple Virtual Connect modules.

By adding multiple uplink ports from the same I/O module, and the Connection Mode is
set to Auto, Virtual Connect will attempt to form a LACP (802.3ad) Link Aggregate
Group (LAG.) A LAG cannot span multiple Virtual Connect modules. Changing the
Connection Mode to Failover will prohibit Virtual Connect from forming a LAG. The
upstream switch must have its 802.3ad configuration mode set to On.
