The SNMP Tool Screen
Token Errors | 4 |
A Token Error may indicate that an active monitor either has detected a recirculating frame or token, or has found that its Timer Valid Transmission (TVX) time has expired before any token has been detected circulating on the ring (i.e.: a lost frame error has occurred). The active monitor is responsible for purging the ring and issuing new tokens in response to these errors.
Frequency Errors | 5 |
A Frequency Error may indicate that the frequency of the incoming signal deviates excessively from that of the reporting station’s onboard crystal oscillator. When frequency errors are detected, the ring enters the monitor contention process to establish a new active monitor.
