Access Gateway
When a AG-capable switch is changed to AG, it will not act as a switch and it cannot be directly
discovered through Brocade Network Advisor. The port on the switch that is connected to AG is the
F_Port and the port on AG that has a connection from switch is the N_Port. AG is considered as a
node from the switch's perspective.
As shown in
switch F1 and F2 connected to ports N1 and N2 of AG. The AG is connected to three HBAs, so the
F_Ports F1, F2, and F3 on AG are connected to the ports n1, n2, and n3 of HBA1, HBA2, and HBA3
correspondingly. There is an internal mapping on AG as N1 is mapped with F1 and F2, and N2 is
mapped with F3.

The end device is represented as the instance of Brocade_Platform. The value of the property
Dedicated is Not Dedicated representing the HBA. The LogicalPortGroup instance is
represented as Brocade_Node and it is associated with Brocade_Platform by
Brocade_NodeInPlatform.
All the ports in end devices are represented as Brocade_NodeFCPort and it associates with
Brocade_Node by Brocade_PortInNode.
The virtualized ports associate with real ports of the end device using the
Brocade_NodeFCPortDependency association. The Brocade_NodeFCport is also associated
with the Brocade_Platform by Brocade_NodePortInPlatform.
The platform instance for the HBA is shown if the HBA is FDMI-enabled.
SANProtocolEndPoint of the switch is associated with the SANProtocolEndPoint of the end
device as Brocade_SANActiveConnection. There is a direct association between the switch and
the virtualized port of the end devices through Brocade_SANActiveConnection. Therefore, the
number of F_Port to N_Port connections is equal to the sum of virtualized ports and real port
of the end device.
