Data Sheet
13.3 IEEE – 802.1 Bridge Management (RFC 1286)
13.3.1 Event Counters
13.3.1.1 InFrames
Counts number of frames received by this port or segment.
Note: A frame received by this port is only counted by this counter if and only if it is for a protocol being processed
by the local bridge function.
13.3.1.2 OutFrames
Counts number of frames transmitted by this port.
Note: A frame transmitted by this port is only counted by this counter if and only if it is for a protocol being
processed by the local bridge function.
13.3.1.3 InDiscards
Counts number of valid frames received which were discarded (i.e., filtered) by the forwarding process.
13.3.1.4 DelayExceededDiscards
Counts number of frames discarded due to excessive transmit delay through the bridge.
13.3.1.5 MtuExceededDiscards
Counts number of frames discarded due to excessive size.
13.4 RMON – Ethernet Statistic Group (RFC 1757)
13.4.1 Event Counters
13.4.1.1 Drop Events
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.
13.4.1.2 Octets
Counts the total number of octets (i.e. bytes) in any frames received.
13.4.1.3 BroadcastPkts
Counts the number of good frames received and forwarded with broadcast address.
Does not include non-broadcast multicast frames.
13.4.1.4 MulticastPkts
Counts the number of good frames received and forwarded with multicast address.
Does not include broadcast frames.
