LACP trunking
• Passive mode – In passive link aggregation, the Brocade port can exchange LACPDU messages
with the port at the remote end of the link, but this port cannot search for a link aggregation
port or initiate negotiation of an aggregate link. In passive mode, the port at the remote end of
the link must initiate the LACPDU exchange.
When you enable link aggregation on a group of Brocade ports, the Brocade ports can negotiate
with the ports at the remote ends of the links to establish trunk groups.
