Using the fddilink Utility
• DIRECTED indicates that this MAC sends beacon frames to notify
the ring of a stuck condition.
• TRACE indicates that this MAC initiates a trace function. Trace
provides a recovery mechanism from a stuck beacon.
• ManufactureData indicates the manufacturer of the communication
adapter or node.
• UserData indicates the communication board used by the node.
• SMT Version Op indicates the field in the SMT header that identifies
the structure of the SMT Info field. This field, with others in the
header, allows all protocol versions to recognize version mismatches.
The value of the Version ID for NIFs (Neighbor Information Frames),
SIFs (Status Information Frames) and ECFs (Echo Frames) value Op,
Hi and Lo is a constant value of 0x0001.
• MAC stands for Media Access Control.
• UpStreamNbr indicates the upstream MAC address of the unit from
which data is received.
• DownStreamNbr indicates the downstream MAC address of the unit
from which data is received.
• OldUpStreamNbr indicates the previous upstream MAC address of
the unit from which data is received.
• OldDownStreamNbr indicates the previous downstream MAC
address of the unit from which data is received.
• PHY indicates Physical Layer Protocol.
• ConPol indicates the connection policies in effect for a node. 0000
means that all possible connections are allowed.
• Cutoff indicates error rate estimate at which a connection is broken.
The range is 10
-4
to 10
-15
. It is displayed as the absolute value of the
base 10 logarithm. The default is 7 (10
-7
).
• Alarm indicates error rate at which a link connection generates an
alarm. The range is 10
-4
to 10
-15
. The default is 8 (10
-8
).
• ConState indicates the state of the connection. The possible values
are Disabled, Connecting, Standby, and Active.
• RemoteType indicates the type of port connector at the other end of
the physical connection. The possible values are A, B, M, S or ? (a
question mark for unknown).
