Setup Guide

Port mapping ensures that all traffic from a specific F_Port always goes through the same N_Port. A single F_Port is mapped
to a single N_Port, or to an N_Port group. To map an F_Port to an N_Port group, map the F_Port to an N_Port that belongs to
that port group. All F_Ports mapped to an N_Port group are part of that N_Port group.
∙ Device mapping
Device mapping is optional. Port maps must exist before you can create device maps. Device mapping allows a virtual port to
access its destination device regardless of the F_Port where the device resides. Device mapping also allows multiple virtual
ports on a single physical machine to access multiple destinations residing in different fabrics.
The preferred method is to map a device WWN to an N_Port group. When a device WWN is mapped to an N_port, and a
failover N_port is also specified, the device can reach the fabric through the primary or secondary N_port only. However, when
a device WWN is mapped to a port group, it can login to the fabric until the last N_port in the particular port group remains
online.
You can map a device to multiple groups. Alternatively, you can map a device to a specific N_Port.
Port mapping
F_Ports must be mapped to N_Ports before the F_Ports can come online. The following figure shows an example in which eight F_Ports
are mapped evenly to four N_Ports on a switch in AG mode. The N_Ports connect to the same fabric through different Edge switches.
