The PAM Subsystem’s Role Within the System
PAM Manager (PAMMAN) Process
The PAMMAN process, $ZZPAM, is a process pair that provides the interface between
the PAM subsystem and the Subsystem Control Point (SCP) process. The SCP process is
required for management of the PAM subsystem. The SCP process is used by the SCF
interactive interface as well as by management applications.
MFIOB (Multifunction I/O Board/Ethernet)
The MFIOB is a ServerNet adapter that is integrated into the processor multifunction
(PMF) CRU and the I/O multifunction (IOMF) CRU. The MFIOB provides testing
functions.
FESA (Fast Ethernet ServerNet Adapter)
The FESA is a CRU that supports one Ethernet 10Base-T or 100Base-TX connection
and communicates with multiple processors through its dual ServerNet interfaces to the
ServerNet fabrics.
E4SA (Ethernet 4 ServerNet Adapter)
The E4SA is a CRU that supports four 10Base-T Ethernet connections and
communicates with multiple processors through its dual ServerNet interfaces to the
ServerNet fabrics.
TRSA (Token-Ring ServerNet Adapter)
The TRSA is a CRU that provides connectivity between the server and other nodes on a
token-ring compliant, software-configurable network that has a speed of either 4 or 16
Mbps.
For information about using the management programming interface to PAM, see the
PAM Management Programming Manual.
SCF Interface
SCF provides the interactive interface for PAM. SCF operates on defined objects which
correspond to physical or functional entities and which have configurable attributes and
adhere to rules of operation such as object hierarchy.
SCF Object Hierarchy
The SCF objects for PAM correspond to software components within the subsystem.
Some objects are subordinate to others. Figure 1-3
shows the hierarchy of the objects in
PAM. Both the PORT and MSAP object are subordinate to the LINE object. The
PROCESS object is superior to the LINE object but shares the LINE object’s name. The
dotted lines between SNATR and LLC2 and SESSION indicate that SNAX/XF or
SNAX/APN have control over those PORT types. In addition to being subordinate to the
PORT object, the LLC2 and SESSION objects can be viewed as subordinate to the
SNATR MSAP object.
