Ethernet 4 ServerNet Adapter (E4SA) and Token
Ring ServerNet Adapter (TRSA)
PORT objects used in systems prior to the ServerNet architecture in the sense that
filters are the final destination for data received from the LAN. The NonStop TCP/IP
process in NonStop S-series systems registers ARP and IP filters through a LIF.
Ethernet 4 ServerNet Adapter (E4SA) and Token Ring ServerNet
Adapter (TRSA)
The E4SA and TRSA are Customer replaceable units (CRUs) installed in an enclosure
of a NonStop S-series system. An E4SA or TRSA contains one or more ServerNet
addressable controllers (SACs) and two physical interfaces (PIFs).
ServerNet Addressable Controller (SAC)
A SAC is the ServerNet addressable entity on an adapter that allows a NonStop
S-series system to communicate to a specific adapter across the X and Y fabrics of a
ServerNet system area network (SAN) connected to a NonStop S-series system. A
SAC can support up to two PIFs.
Physical Interface (PIF)
The PIF corresponds to the physical connection to the LAN, which is the
industry-standard Ethernet port on an E4SA or token ring port on a TRSA.
Subsystem Architecture
The TCP/IP subsystem consists of a process controlling as many as 13 subnets. Each
subnet can have several routes associated with it. The number of routes that can be
added depends on system resources.
You can manage the TCP/IP subsystem through both interactive and programmatic
interfaces.
The interactive interface for managing the TCP/IP subsystem actually consists of two
interfaces:
•
The Subsystem Control Facility (SCF), which can be used to monitor, configure,
and control the subsystem. SCF provides an operator interface to the Subsystem
Control Point (SCP) that provides an interface to the TCP/IP subsystem.
•
The ViewPoint application, which can be used to retrieve event messages
(previously sent to EMS by the subsystem) interactively.
For further details on the interactive interfaces, see the TCP/IP Configuration and
Management Manual and the ViewPoint Manual.
The programmatic interface for managing the TCP/IP subsystem also consists of two
interfaces:
•
The control-and-inquiry interface, which provides control and inquiry capability to
an application program. This interface (which is also provided by the SCP) allows
