Zone-Based Aliases
Aliases are limited to the specified VSAN
Zone aliases are part of the zoning configuration, the
alias mapping cannot be used to configure other features.
Cisco MDS 9000 Family Configuration Guide
20-2
The device alias information is independent of your VSAN configuration.
The device alias configuration and distribution is independent of the zone server and the zone server
database.
You can import legacy zone alias configurations without loosing data.
The device alias application uses the Cisco Fabric Services (CFS) infrastructure to enable efficient
database management and distribution. Device aliases use the coordinated distribution mode and the
fabric-wide distribution scope (see
When you configure zones, IVR zones, or QoS features using device aliases, and if you display these
configuration, you will automatically see that the device aliases are displayed along with their
respective pWWNs.
You can only assign device aliases to pWWNs.
Ensure that the mapping between the pwwn and the device alias to which it is mapped has a one to one
relationship. A pWWN can be mapped to only one device alias and vice versa.
A device alias name is restricted to 64 alphanumeric characters and may include one or more of the
following characters:
a to z and A to Z
–
1 to 9
–
- (hyphen) and _ (underscore)
–
$ and ^

You can define device aliases without specifying the VSAN number.
You can also use the same definition in one or more VSANs without
any restrictions.
Device aliases can be used to any feature that uses the pWWN.
