FDDI Management
Figure 4-7. SMT/MAC Configuration Window
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.
