4.2.5 3F00-01/3F55-01 Port PHY Status

Physical Layer Protocol (PHY) is the FDDI standard that defines
symbols, line states, clocking requirements, and the encoding of data for
transmission. Versions of system software prior to 2.3 support SMT
version 6.2. In the sections that follow, the SMT version 6.2 MIB
variables are presented first, followed by the SMT version 7.3 versions.

The following status information is available for each of the two PHYs of
the FDDI port:
• Indicates the PHY's
• Indicates the PC_Type of the PHY's neighbor.
