Brocade Access Gateway and NPIV

Access Gateway (AG) allows you to configure the enterprise fabric to handle additional N_Ports

instead of domains by configuring F_Ports to connect to the fabric as N_Ports. This increases the

number of device ports that can be connected to a single fabric. Multiple AGs can connect to the

DCX enterprise-class platforms, directors, and switches.

Access Gateway is compatible with Fabric OS, M-EOS v9.1 or v9.6 and later. The switches in AG

mode are logically transparent to the host and the fabric. The number of hosts that have access to

the fabric can be increased without increasing the number of switches. This simplifies the

configuration and management in a large fabric by reducing the number of domain IDs and ports.

NOTE

The SMI Agent does not support the discovery of an Access Gateway-enabled switch as a seed

switch, using Extrinsic method, except for the Brocade Encryption Switch.

Node Port Initialized Virtualization (NPIV) allows a single Fibre Channel port to appear as multiple

distinct ports. It provides a separate port identification and security zoning within the fabric for

each operating system image. Each operating system image has its own unique physical port.

For additional information about Access Gateway, refer to the Access Gateway Administrator’s

Guide.

For additional information about NPIV, refer to the Fabric OS Administrator’s Guide.

Registration

Figure 43 shows the SNIA Profile Registration Profile model to advertise the NPIV profile.

FIGURE 43 NPIV profile registration model

When an Access Gateway switch exists with devices attached in the discovered fabric, the

Brocade_RegisteredProfile (N_Port Virtualizer) is mapped to Brocade_AccessGateWay using

Brocade_ElementConformsToProfile association class.
