Fibre Channel ports are configured as N_Ports. The FCoE ports are divided into six groups, or trunks, consisting of four ports each. All four ports in a group are mapped to one N_Port.

especially during failover conditions and system power up. This is especially true when a reasonably large number of devices must connect to the same fabric through a single port group. The following aspects of device mapping are important to note: • Logins from a device mapped to a specific N_Port - Dell Brocade 300 | Access Gateway Administrator's Guide 7.1.0 - Page 43
. Note that you can map one or multiple WWNs to one N_Port to allow multiple devices to log in through one N_Port. Access Gateway Administrator's Guide 23 53-1002743-01 - Dell Brocade 300 | Access Gateway Administrator's Guide 7.1.0 - Page 44

Device mapping to port groups (recommended) Mapping NPIV devices to a port group is an ideal choice when a reasonably sized set of devices must connect to the same group of N_Ports, and you want - Dell Brocade 300 | Access Gateway Administrator's Guide 7.1.0 - Page 45

For example, if system administrators need to push a set of port group changes and a set of device mapping changes, they could push them in either order without error.

2 N_Port configurations N_Port configurations By default, on embedded switches, only the internal ports of Access Gateway are configured as F_Ports.

ports are configured in N_Port lock mode when you enable Access Gateway. Access Gateway connects only FCP initiators and targets to the fabric. It does not support other types of ports, such as ISL (interswitch link) ports. By default, on fabric switches, the port types are not locked.

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 - Dell Brocade 300 | Access Gateway Administrator's Guide 7.1.0 - Page 95
targets with various lower Fibre Channel speeds (such as 1, 2, or 4 Gbps) onto a single high-speed uplink port to the core fabric. This reduces the number of core fabric ports used by target devices and allows higher scalability.
