Fibre Channel Ports

G_Ports self-configure in the following ways:
„
F_Port when connected to a public device
„
E_Port when connected to another FC-SW-2 compliant switch
A TL_Port supports private loop devices and must be configured explicitly. Refer 
to the SANbox2-8c/16 Switch Management User’s Guide for more information 
about defining port modes.
2.2.3.1
Fabric Ports
An FL_Port can support a loop of up to 126 public devices. An FL_Port can also 
configure itself during the fabric login process as an F_Port when connected to a 
single public device (N_Port).
2.2.3.2
Translated Loop Port
A TL_Port supports a loop of up 124 private target devices with the ability to 
communicate with up to 63 “off-loop” public devices. The TL_Port acts as a proxy 
for the off-loop device translating private frames into and from public frames. The 
set of off-loop devices are maintained in the TL_Port’s translation entries list. The 
switch firmware automatically creates an entry in the translation entries list for 
each off-loop initiator device that attempts to establish communication. Soft or 
VPF zoning can be used to limit the number of potential initiators to 63. Zone 
membership must be done by worldwide name, or domain ID and port ID. 
TL_Ports connect to devices that conform to the Fibre Channel-Private Loop SCSI 
Direct Attach (FC-PLDA) standard. Devices connected to TL_Ports are registered 
with the Name Server.
2.2.3.3
Expansion Port
E_Ports enable you to expand the fabric by connecting SANbox2-16 switches with 
other FC-SW-2 compliant switches. SANbox2-16 switches self-discover all 
inter-switch connections. Refer to 
 for more 
information about multiple chassis fabrics.
