Figure 13-60: 100BASE-T1 decode results table and details
The content of the "Decode results" table in Figure 13-60 is described in Table 13-13:
Table 13-13: Content of the "Decode results" table
Column Description
Frame Frame count
Type Type of frame (e.g. Idle, MAC or data)
State Overall state of the frame: either OK or the relevant error condition (preamble,
CRC or SFD)
Start Start time of the frame
Stop Stop time of the frame
Destination Address Destination address of the frame
Source Address Source address of the frame
Type/Length The sub-protocol (e.g. HTML, video, etc.) determines what meaning this field has.
Since the content of this data area is not decoded, the interpretation of this field is
ambivalent. It could either be the word type (specific for the sub-protocol) or the
word length.
Data Values of the data bytes in a frame. The table shows a truncated version; to see all
the bytes in a separate data table, activate "Show details". The data format is
always hexadecimal.
CRC Frame Check (Cyclic Redundancy Code, CRC)
Bit rate Value of the bit rate
Zooming on decoded results
The zoom functions allow you to analyze the decode results in more detail. If "Zoom
coupling" is enabled, the decode zoom and result table are synchronized; if you select
a row in the result table, this result is shown in the decode zoom.
