Access Gateway mapping
When operating in AG mode, you must specify pre-provisioned routes that AG will use to direct
traffic from the devices (hosts or targets) on its F_Ports to the ports connected to the fabric using
its N_Ports. This is unlike Native switch mode where the switch itself determines the best path
between its F_Ports. This process of pre-provisioning routes in AG mode is called “mapping.”
During mapping, device World Wide Names (WWNs) or F_Ports are assigned to N_Ports and N_Port
groups on the switch running in AG mode. Mapping ensures that a device logging in to the switch
will always connect to the fabric through a specific N_Port or N_Port group. Two types of mapping
are available:
• Port mapping
A specific F_Port is mapped to a specific N_Port. This ensures that all traffic from a specific
F_Port always goes through the same N_Port. To map an F_Port to an N_Port group, simply
map the port to an N_Port that belongs to that port group. All F_Ports mapped to that N_Port
will be part of that N_Port group.
• Device mapping (optional)
A specific device WWN is mapped to N_Port groups (preferred method) or to specific N_Ports.
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.
Device mapping is optional and should be added on top of existing port maps. Port mapping must
exist at all times.
