Reference Manual
Understanding FDDI (3CS-360) is a pragmatic independent study course and
reference manual written for professionals involved in the design,
implementation, or support of multivendor FDDI networks.
Chapters 1 through 5 contain core information about FDDI. These chapters
explore critical elements of an FDDI environment, including attachment
stations, MAC interfaces, concentrators, and optical bypass switches. Port
keying and configuration, internetworking, ring startup, operation, fault
isolation and ring recovery, light properties, fiber media, and optics are also
covered.
Chapters 6 through 12 constitute a 250-page technical reference that takes
you down to the engineering level. Here 3Com interprets the FDDI standards
to provide tangible and accessible information on all four FDDI protocol
layers and the SMT Management Information Base.
This text-based course comes with a testing diskette to guide and reinforce
the learning process. Students who pass the test receive a certificate of
completion.
