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

We recommend that both ends of a VSAN trunking ISL belong to the same port VSAN. On platforms
or fabric switches where the port VSANs are different, one end returns an error, and the other is not
connected.
To avoid inconsistent configurations, disable all E ports with a shutdown command before enabling
or disabling the VSAN trunking protocol.
