NA ISL is not supported.1 Yes Connects the switch to other switches to form a fabric. 1. The switch is logically transparent to the fabric, therefore it does not participate in the SAN as a fabric switch. Access Gateway limitations The limitations of Access Gateway are as follows: • Only the switch platforms and embedded switch platforms listed in "Supported hardware and software" on page xiii. • The maximum number of devices that can be connected to a Fabric OS switch through AG depends on the maximum number of local devices supported by Fabric OS. • Loop devices are not supported. • Port groups cannot be overlapped. This means that an N_Port cannot belong to two different groups. Access Gateway Administrator's Guide 5 53-1001345-01
