Each type of IEEE 802.5 error detected by the selected station port is described in
detail below.
Line Errors
The Line Errors Þeld displays the number of the line errors detected by the
selected port. This error indicates the presence of a non-data bit between the
starting and ending delimiters of data or a frame check sequence (FCS) error.
Burst Errors
The Burst Errors Þeld displays the number of burst errors detected by the selected
port. This error indicates a bit information encoding error when there are no
transitions between 0 and 1 over Þve half-bit times.
A. C. Errors
The A. C. Errors Þeld displays the number of A. C. errors detected by the selected
port. These errors count protocol data units (PDUs) that contain errors in the A or
C bits.
