Translated Loop Features
• Each TL_Port maintains up to 125 AL_PA addresses on the Private Loop.
When one of these AL_PA addresses communicates with an “off-loop”
device, the TL_Port acts as a proxy for the off-loop device on the Private
Loop. This means that the TL_Port handles all loop primitives on behalf of
the off-loop device.
• Each TL_Port may proxy up to 31 off-loop devices. These off-loop devices
must be Public devices (connected to F, or FL_Ports) or Private devices on
other TL_Ports.
• The set of off-loop devices that a single TL_Port may proxy may overlap or
exclude the devices accessed by other TL_Ports in the same fabric.
• The set of off-loop devices proxied by a TL_Port is contained in its transla-
tion entries list.
The translation entries list for a TL_Port connected to Private targets will
contain the initiators (both Public and Private) that try to communicate with
