11.3.1.4
Counts number of frames transmitted by this port.
Note:
processed by the local bridge function.
11.3.1.5
Counts number of valid frames received which were discarded (i.e. filtered) by the forwarding process.
11.4
11.4.1
11.4.1.1
Counts number of times a packet is dropped, because of lack of available resources. DOES NOT include all packet
dropping -- for example, random early drop for quality of service support.
Use ZL50411 counter “Drop”, C[26].
11.4.1.2
Counts the total number of octets (i.e. bytes) in any frames received.
Use ZL50411 counter “Bytes Received”, C[5].
Note: max. frame size may be BUF_LIMIT, if enabled on this port.
11.4.1.3
Counts the number of frames received, good or bad.
A frame transmitted by this port is only counted by this counter if and only if it is for a protocol being
