Physical Interface Statistics

Transmit
The percentage of line capacity currently used for transmitting.

Receive
The percentage of line capacity currently used for receiving.

Ave. frames/s
The average per-second rate of transmitted and received frames on this line.

Frames/s
The current per-second rate of transmitted and received frames on this line.

Ave. bytes/s
The average per-second rate of transmitted and received bytes on this line.

Bytes/s
The current per-second rate of transmitted and received bytes on this line.

Clock timeout
The number of times the adapter firmware is unable to detect a clock signal. This increments only when external clocking is configured.

Overrun
The number of erroneously long frames received. These are frames that are too large for the adapter to buffer. This can be caused by any of the following:

External clocking is configured and the device providing the clock is not working.
Internal clocking is configured and the adapter is not working properly.
The cable or line is defective.
The DataFire Electrical Interface is not configured correctly.

CRC
The number of frames received with cyclic redundancy check (CRC) errors. This indicates problems with the line itself or with the Clocking or Electrical Interface configuration.

Bit error
The number of frames received with bit errors.

Over flow
The number of received frames that exceeded the configured maximum frame size.

Abort
The number of abort frames received.
