Monitoring the QLogic SANbox Fibre Channel Switch with NetCentral
Preliminary
Troubleshooting with NetCentral
NetCentral reports status, warnings, and alarms using messages that are easy to
understand. Suggested corrective actions are presented along with failure
information. If you have any trouble interpreting any of the problems or suggested
solutions, contact Grass Valley support.
Ports\Sync Losses
[module-port]
Sync Losses indicates the number of times the port went into the “loss of
synchronization” state where it encountered continuous Disparity errors during that
sampling interval.
This is likely an indicator for a faulty connector or cable. These are also caused when
the device connected to the port is restarted, replaced or being serviced when the Fibre
Channel cable connected to the port is temporarily disconnected.
If the port is in the “loss of synchronization” state for longer than a specific period, the
port will get into the link failure state which could degrade the performance of the
Fibre Channel link.

Losses
[module-port]
Signal losses is the number times the port detected a loss of the electrical or optical
signal used to transfer data on the port during that sampling period.
This is likely an indicator for a faulty connector or cable. These are also caused when
the device connected to the port is replaced or being serviced when the Fibre Channel
cable connected to the port is temporarily disconnected.
If the port is in the “loss of signal” state for longer than a specific period, the port will
get into the link failure state which could degrade the performance of the Fibre
Channel link.
Errors
Ports\CRC Errors
[module-port]
CRC Errors is the number of Fibre Channel frames handled by the port that containing
checksum errors during that sampling period. Typically the error is recovered by
retransmitting the frame and the error will go unnoticed by the device connected to the
port.
These are usually recoverable errors and will not degrade system performance unless
their occurrence is sustained when the data cannot be relayed after retransmissions.
