In a multiple-mode trunk, all the interfaces are active. This provides greater speed than a single interface.
A multiple-mode trunk requires a switch that supports manually configurable trunking. The switch automatically determines how the load is balanced among the interfaces, during normal operation and when a takeover occurs because of a failed interface.
To use a multiple-mode trunk, you need a switch that supports manually configurable trunking over multiple port connections. The switch determines how to forward incoming packets to the filer. You configure the switch so that all the port connections are part of a single logical port.
