Fabric OS command support This section describes how Fabric OS commands are supported on the Brocade 8000 in AG mode. • The following commands are not supported on the Brocade Guide - Dell PowerConnect Brocade M5424 | Brocade 7.1.0 Access Gateway Administrator's G - Page 92
and 6510 The Brocade 6505 and 6510 can function in either Fabric OS Native mode or Brocade Access Gateway mode.These switches are shipped in Fabric OS Native mode. All ports on demand (POD) licenses must be present to support Access Gateway. 72 Access Gateway Administrator's Guide 53-1002743-01 - Dell PowerConnect Brocade M5424 | Brocade 7.1.0 Access Gateway Administrator's G - Page 93
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.

• Direct target attachment to AG is only supported if the AG module is also connected to a core fabric. A switch module running in AG mode does not provide Name Services on its own, and routing to the target not get mapped to a single N_Port. 74 Access Gateway Administrator's Guide 53-1002743-01 - Dell PowerConnect Brocade M5424 | Brocade 7.1.0 Access Gateway Administrator's G - Page 95
Gateway mode is normally used as host aggregation. In other words, a switch in AG mode aggregates traffic from a number of host systems onto a higher scalability.

you to further increase the ratio of hosts to fabric ports to beyond what a single switch in AG mode can support. Access Gateway cascading allows you to link two Access Gateway (AG) switches back to back. The AG switch that is directly connected to the fabric is referred to as the Core AG.
