Table 5-1. Frame Breakdown Pie Chart
Statistic DeÞnition
Abort Trans The total number of abort sequences transmitted on this ring.
This counter is incremented when a station transmits an abort
delimiter while transmitting.
Internal The total number of internal errors detected by a station on this
ring. This counter is incremented when a station transmits an
abort delimiter while transmitting.
Signal Loss The number of times this interface has detected the loss of signal
condition from the ring.
Lobe Wire The number of times the interface has detected an open or short
circuit in the lobe data path. The adapter will be closed and
dot5RingState will signify this condition.
Frequency The total number of frequency errors on this ring.
Table 5-2. Isolating Errors Pie Chart
Statistic DeÞnition
Line Incremented when a frame or token is copied by a station, the E
bit is zero in the frame or token, and a non-data bit (J or K bit)
between the SD and the ED of the frame or token, or there is an
FCS error in the frame. It represents the total number of line
errors that have occurred on this ring.
Burst This counter is incremented when a station detects the absence
of transitions for Þve half-bit timers (burst-Þve error). Burst
represents the total number of burst errors that have occurred
on this ring.
A/C The total number of address/copied errors that have occurred on
this ring. This counter is incremented when a station receives an
AMP or SMP frame and denotes a station that cannot set the AC
bits properly.
Table 5-3. Non-Isolating Errors Pie Chart
Statistic DeÞnition
Lost Frames The total number of times a Token Ring Rotation (TRR) station
timer expired while trying to transmit.
Congestions The total number of times a station recognizes a frame
addressed to it, but the station has no available buffer space.
Frame Copied The total number of times a station recognizes a frame
addressed to it, and detects that the FS Þeld A bits are set to 1.
