Description
Readable Frames
Number of good frames received by the port.
Readable Octets
Number of good octets received by the port.
CRC Errors
Number of CRC errors.
Alignment Errors
For 10 Mbps ports, the counter records alignment errors (mis-
synchronized data packets). For 100 Mbps ports, the counter
records the sum of alignment errors and code errors (frames
received with rxerror signal).
Frames Too Long
Number of times frame length has exceeded the maximum
allowable size (that is, 1518 bytes).
Short Events
Number of short fragments.
Runts
Number of fragments (that were too long to qualify as short events).
Collisions
Number of simultaneous node transmissions detected by this device.
Late Events
Number of frames where a collision occurred late in the transmission.
Data Rate
Mismatches
Number of frames for which the data rate does not match the local
frequency.
