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 to 125 private initiator devices or up to 124
private target devices with the ability to communicate with “off-loop” devices. This
includes public fabric devices and private devices on other TL_Ports. 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.

Attach (FC-PLDA) standard. Devices connected to TL_Ports are registered with

A TL_Port acts as a proxy for the off-loop device translating private frames into
and from public frames. Each TL_Port can proxy up to 63 off-loop initiator devices
or up to 64 off-loop target and initiator devices. The set of off-loop devices are
maintained in the TL_Port’s translation entries list.

maintained in the TL_Port’s translation entries list.
■
For a TL_Port connected to private target devices, 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.

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
other FC-SW-2 compliant switches. SANbox2-16 switches self-discover all
inter-switch connections. Refer to
for more
information about multiple chassis fabrics.
