> # About FC Alias Creation

> You can assign an alias name and configure an alias member using the following values:

> - pWWN—The WWN of the N or NL port is in hex format (for example, 10:00:00:23:45:67:89:ab).
> - fWWN—The WWN of the fabric port name is in hex format (for example, 10:00:00:23:45:67:89:ab).
> - FC ID—The N port ID is in 0xhhhhhh format (for example, 0xce00d1).
> - Domain ID—The domain ID is an integer from 1 to 239. A mandatory port number of a non-Cisco switch is required to complete this membership configuration.
> - IPv4 address—The IPv4 address of an attached device is in 32 bits in dotted decimal format along with an optional subnet mask. If a mask is specified, any device within the subnet becomes a member of the specified zone.
> - IPv6 address—The IPv6 address of an attached device is in 128 bits in colon- (:) separated) hexadecimal format.
> - Interface—Interface-based zoning is similar to port-based zoning because the switch interface is used to configure the zone. You can specify a switch interface as a zone member for both local and remote switches. To specify a remote switch, enter the remote switch WWN (sWWN) or the domain ID in the particular VSAN.

> Tip The Cisco NX-OS software supports a maximum of 2048 aliases per VSAN.
