Configuring VSAN Trunking
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).

Auto
The preferred configuration on the Cisco SAN switches is that one side of the trunk is set to auto and the other
is set to on.
Note
When connected to a third-party switch, the trunk mode configuration has no effect. The Inter-Switch
Link (ISL) is always in a trunking disabled state.
