Description
Fabric port—Supports a single public device (N_Port).
Fabric loop port—Self-discovers a single device (N_Port) or
a loop of up to 126 public devices (NL_Port).
Generic port—Self-discovers as an F_Port or an E_Port.
Generic loop port—Self-discovers as an F_Port, FL_Port, or
an E_Port. GL_Port is the default port type. A single device
on a public loop will attempt to configure as an F_Port first,
then if that fails, as an FL_Port.
Expansion port—The mode that a G_Port or GL_Port is in
when attached by an ISL (inter-switch link) to another fibre
channel switch.
Transparent Router port—Allows devices on a remote fabric
to be mapped to devices on the local 8/20q Fibre Channel
Switch fabric. TR_Ports do not support online port
diagnostics (see "Testing
NOTE: The 8/20q Fibre Channel Switch with TR ports
enabled is not supported by Simple SAN Connection
Manager (SSCM) at this time. SSCM may disrupt the TR
mappings, therefore rendering communication between the
8/20q Fibre Channel Switch and a remote fabric
inoperable. Users wishing to manage their SAN with SSCM
should not enable TR ports on the 8/20q Fibre Channel
Switch.
Donor port—Allows buffer credits to be used by another
port.
