FDDI Management
The SMT Configuration portion of the window provides the following
information about the current configuration of each SMT entity present in the
SmartSwitch chassis:
SMT Index
Displays the index number of the Station Management (SMT) entity to which
each port is attached. Each FDDI NIM module has two SMT entities — one for
each front panel interface. If you have launched the SMT/MAC Configuration
application from the Hub View Module menu, these two SMT entities will be
indexed by front panel interface numbers (FP 1 and FP 2, as illustrated above); if
you have launched the application from the command line (or if your 7C0x hub
has more than one FDDI NIM installed), the front panel designations will not
appear. For multiple NIMs, SMT entities will be indexed from left to right in the
hub, and from top (front panel port 1) to bottom (front panel port 2) on each
module.
Version
Displays the operational SMT version being used by each SMT entity. SMT frames
have a version ID field that identifies the structure of the SMT frame Info field.
The version number is included in the SMT frame so that a receiving station can
determine whether or not its SMT version is able to communicate with the SMT
version of another station. Knowing the version number allows the stations to
handle version mismatches. Each FDDI station supports a range of SMT versions.
