Brocade Access Gateway Administrator's Guide (Supporting Fabric OS v7.3.0) - Manual (Page 89)

• 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 devices must be established by the core fabric.
• Hosts and targets cannot be mapped to the same N_Port.
• Redundant configurations should be maintained so that when hosts and targets fail over or fail
back, they do not get mapped to a single N_Port.
• Hosts and targets should be in separate port groups.
• Direct target attachment configurations are not enforced.
Target aggregation
Access 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 single uplink N_Port. Similarly, many targets
can be aggregated onto to a single uplink N_Port, as shown in the figure below. Target aggregation has
many applications. As one example, you can consolidate targets with various lower Fibre Channel
