Switch Port Types
New Sun StorEdge SAN 4.0 Release Port Types
The Sun StorEdge SAN 4.0 release port types now follow industry standards.
E_Ports replace T_Ports for switch-to-switch connections. G_ and GL_Ports
automatically configure to F_, FL_, or E_Ports upon device detection. Private loop
devices that require SL ports can not connect to the new switches.
The 2-Gbit Sun StorEdge network adapters in this release will recognize the private
loop arrays as fabric devices when they are connected with TL_Ports or L_Ports.

Sun StorEdge and Brocade Communications Systems Port Descriptions
Port Nomenclature Function
E_Port Expansion or inter-switch port. A type of switch port that can
be connected to an E_Port of another switch to, in effect, create
a cascading interswitch link (ISL).
F_Port Fabric port. A fabric port that is point-to-point only, not loop
capable, and used to connect N_Ports to the switch.
FL_Port Fabric loop port. A fabric port that is loop-capable and used to
connect NL_Ports to the switch.
G_Port Generic port. This port can automatically configure as either an
E_Port or an F_Port. A port is defined as a G_Port when it is not
yet fully connected or has not yet assumed a specific function in
the fabric.
GL_Port Generic loop port. This port can automatically configure as
either an E_Port, F_Port, or an FL_Port. A port is defined as a
G_Port when it is not yet fully connected or has not yet
assumed a specific function in the fabric.
