Traffic is distributed dynamically and in order over this trunk group, achieving greater performance with fewer links. Within the trunk group, multiple physical ports appear as a single port, thus simplifying management. Trunking also improves system reliability, by maintaining in-order delivery of data and avoiding I/O retries if one link within the trunk group fails. Trunking is frame-based instead of exchange-based. Because a frame is much smaller than an exchange, this means that frame-based trunks are more granular and better balanced than exchange-based trunks and provide maximum utilization of links. The Trunking license is required for any type of trunking, and must be installed on each switch that participates in trunking. For details on obtaining and installing licensed features, see Chapter 18, "Administering Licensing". Fabric OS Administrator's Guide 533 53-1002745-02
