> # Device Alias Mode Distribution

> If the device alias distribution is turned on, it is distributed to the other switches in the network whenever there is a change in the mode. You cannot change the mode from basic to enhanced unless all the switches are upgraded to Cisco SAN-OS Release 3.1. The device alias enhancements will not apply unless the entire fabric is upgraded to Cisco SAN-OS Release 3.1.

> Note When all the switches are upgraded to Cisco SAN-OS Release 3.1, you cannot automatically convert to enhanced mode. You do not need to change to enhanced mode, you can continue working in the basic mode.
