Modification

This command was introduced.

If a switch is reachable over both IP and Fibre Channel, application data will be distributed over

Fibre Channel.

You can select either an IPv4 or IPv6 distribution when CFS is enabled over IP.

Both IPv4 and IPv6 distribution cannot be enabled on the same switch.

A switch that has IPv4 distribution enabled cannot detect a switch that IPv6 distribution enabled.

The switches behave as if they are in two different fabrics even though they are connected to each

End with CNTL/Z.
