> # Zone Aliases Versus Device Aliases

> Table 27-1 compares the configuration differences between zone-based alias configuration and device alias configuration.

> Table 27-1 Comparison Between Zone Aliases and Device Aliases
> Zone-Based Aliases | Device Aliases
> --- | ---
> Aliases are limited to the specified VSAN. | 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.
> Zone aliases are part of the zoning configuration. The alias mapping cannot be used to configure other features. | Device aliases can be used with any feature that uses the pWWN.
> You can use any zone member type to specify the end devices. | Only pWWNs are supported along with new device aliases such as IP addresses.
> Configuration is contained within the Zone Server database and is not available to other features. | Device aliases are not restricted to zoning. Device alias configuration is available to the FCNS, zone, fcping, traceroute, and IVR applications.
