transmissions. This counter is incremented by one each time that a port automatically isolates as a consequence of false carrier events. The conditions which cause a port to automatically isolate are defined by the transition from the False Carrier state to the Link Unstable state. The port automatically recovers.

Symbol Errors (100Mbps only): Total symbol errors for 100Mbps transmissions. This counter is incremented by one for each valid length packet received at the port with at least one occurrence of an invalid data symbol. This can increment only once per valid carrier event. The approximate minimum time for rollover of this counter is 7.4 hours at 100Mbps.

Total Errors: Total errors received by the port including FCS errors, Align errors, Frame Too Long, Short Events, Late Events, Very Long Events and Rate Mismatch.
