Displayed items are briefly described in the following table.
Field Description
Hub ID Hub identifier within the stack.
Position The physical position in the stack (as determined by position from the top of the Stacking Cable).
Port ID Port identifier on the hub.
Readable Frames Number of good frames received.
Readable Octets Number of good octets received.
CRC Errors Number of Ethernet Cyclic Redundancy Check errors.
Alignment Errors Number of mis-synchronized data packets detected by this device.
Frames Too Long Number of times frame length has exceeded the maximum allowable size (i.e., 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 port.
Late Events Number of frames where a collision occurred late in the transmission.
Data Rate Mis. Number of frames for which the data rate does not match the local frequency.
Auto Partitions Number of times this port has been automatically partitioned due to jabber.
Total Errors Total number of errors, including CRC, alignment, FramesTooLong, ShortEvents, LateEvents,
Jabber, and DataRateMismatches detected on this port.
Last Source Addr. Last source address (LSA). Most recently recorded address of device that generated the most
recent packets seen on the port.
LSA Changes Number of times the source address has changed.
Symbol Errors Number of symbol errors (i.e., code-group errors including collision artifacts or transmission errors).
Note that these errors are unique to 100Mbit/s analog signals.
