Connectivity of multiple devices overview
This chapter describes how to connect multiple devices to a switch in Access Gateway (AG) mode,
and discusses Edge switch compatibility, target aggregation, direct target attachment, port
requirements, NPIV HBA, and interoperability. Switches in AG mode can connect to third-party
fabrics with the following firmware versions:
• M-EOSc v9.6.2 or later and M-EOSn v9.6 or later
• Cisco MDS Switches with SAN OS v3.0(1)
Considerations for connecting multiple devices
Consider the following points when connecting multiple devices to a switch in AG mode:
• AG does not support daisy chaining when two AG devices are connected to each other in a loop
configuration.
• Loop devices and FICON channels/control unit connectivity are not supported.
• When a switch is in AG mode, it can be connected to NPIV-enabled HBAs, or F_Ports that are
NPIV-aware. Access Gateway supports NPIV industry standards per FC-LS-2 v1.4.
