11.2.1.1
Counts the number of frames of valid frame length that have been received on this port.
Use ZL50411 counter “Total Frames Received”, C[8].
Note: max. frame size may be BUF_LIMIT, if enabled on this port.
11.2.1.2
Counts the number of bytes (i.e. octets) contained in valid frames that have been received on this port.
Use ZL50411 counter “Total Bytes Received”, C[7].
Note: max. frame size may be BUF_LIMIT, if enabled on this port.
