About Trunk Mode

By default, trunk mode is enabled in all Fibre Channel interfaces. However, trunk mode configuration takes
effect only in E-port mode. You can configure trunk mode as on (enabled), off (disabled), or auto (automatic).
The default trunk mode is on. The trunk mode configurations at the two ends of the link determine the trunking
state of the link and the port modes at both ends (see the following table).
