11.4.1
Event Counters
11.4.1.1
DropEvents
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 ZL50408 counter “Drop”, C[26].
11.4.1.2
Octets
Counts the total number of octets (i.e. bytes) in any frames received.
Use ZL50408 counter “Bytes Received”, C[5].
Note: max. frame size may be BUF_LIMIT, if enabled on this port.
11.4.1.3
Pkts
Counts the number of frames received, good or bad.
Use ZL50408 counter “Frames Received”, C[6].
Note: max. frame size may be BUF_LIMIT, if enabled on this port.
11.4.1.4
BroadcastPkts
Counts the number of good frames received and forwarded with broadcast address. Does not include
non-broadcast multicast frames.
Use ZL50408 counter “Broadcast Frames Received”, C[11].
