Connectivity of multiple devices overview
This chapter describes how to connect multiple devices to a switch in Access Gateway (AG) mode,
discusses Edge switch compatibility, port requirements, NPIV HBA, and interoperability. Access
Gateway supports Direct Target Attach, which allows you to directly attach a target device to a
switch in AG mode if the AG switch is connected to an external fabric. AG does not support daisy
chaining when two AG devices are connected to each other. Switches in AG mode can connect to
other types of fabrics on Edge switches with the following firmware versions:
• M-EOSc v9.6.2 or later and M-EOSn v9.6
• Cisco v3.0(1) or later, v3.1(1) or later, and v3.2(1) or later.
• Only FCP initiator ports can be connected to a switch in AG mode as F_Ports. FCP target ports
are supported if a switch in AG mode is connected to an external switch. 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.
Fabric and Edge switch configuration
To connect hosts to the fabric using Access Gateway, configure the fabric using the following
parameters. These parameters apply to Fabric OS, M-EOS, and Cisco-based fabrics:
• Install and configure the switch as described in the switch’s Hardware Reference Manual
before performing these procedures.
• Verify that the interop mode parameter is set to 0, Brocade Native mode, or the switch mode is
in Native mode.
• Configure the F_Ports on the Edge switch to which Access Gateway is connected as follows:
• Enable NPIV.
• Disable long distance mode.
