Fabric Attach and Switched UNI

With the C-VLAN UNI feature, I-SID-to-VLAN mappings must be unique across the network. With the Transparent Port UNI (ELAN Transparent) feature, you can map an entire port or MLT to an I-SID.

With the Switched UNI feature, you can associate many different C-VID/port or C-VID/MLT list combinations to a single I-SID.

Switched UNI and FA

FA brings the capability of automatically creating Switched UNI I-SIDs on a switch, without manual intervention. The I-SIDs thus created are ELAN I-SIDs with endpoints of type Switched UNI, and are by default for Layer 2. MAC learning takes place and there is an any-to-any relationship. For Layer 3 participation, you must configure a platform VLAN with the same I-SID value as that of the I-SID in a learned FA mapping.

Note

Note

The number of Switched UNI I-SIDs created are different for different product families. For more information, see Fabric Engine Release Notes.
