Chapter 12 Performance Monitoring
12.6.2 ASAP Card Ethernet Performance Monitoring Parameters
Tx Multicast Packets Number of broadcast packets transmitted since the last counter
reset.
Rx Bytes Number of bytes received since the last counter reset.
Tx Bytes Number of bytes transmitted since the last counter reset.
Rx Errors The number of inbound packets (or transmission units), that
could not be delivered to a higher-layer protocol because of
errors.
Tx Errors The number of outbound packets (or transmission units), that
could not be transmitted because of errors.
Rx FCS errors Number of packets with a frame check sequence (FCS) error.
FCS errors indicate frame corruption during transmission.
Rx Align errors Number of packets with received incomplete frames.
Rx Runts The total number of packets received that were less than
64 bytes long (excluding framing bits, but including FCS bytes)
and were otherwise well formed.
Rx Jabbers The total number of packets received that were longer than
1518 bytes (excluding framing bits, but including FCS bytes),
and had either a bad FCS with an integral number of bytes (FCS
error) or a bad FCS with a nonintegral number of bytes
(alignment error).
Rx Giants The total number of packets received that were longer than
1518 bytes (excluding framing bits, but including FCS bytes)
and were otherwise well formed.
Rx Discards The number of inbound packets that were chosen to be
discarded even though no errors had been detected to prevent
their being deliverable to a higher-layer protocol. One possible
reason for discarding such a packet could be to free up buffer
space.
Tx Discards The number of outbound packets that were chosen to be
discarded even though no errors had been detected to prevent
their being transmitted. One possible reason for discarding such
a packet could be to free up buffer space.
Rx Pause Frames Number of received Ethernet IEEE 802.3z pause frames.
Tx Pause Frames Number of transmitted IEEE 802.3z pause frames.
Port Drop Counts Number of received frames dropped at the port level.
etherStatsDropEvents Number of received frames dropped at the port level.
etherStatsOctets The total number of bytes of data (including those in bad
packets) received on the network (excluding framing bits but
including FCS bytes.
etherStatsPkts The total number of packets (including bad packets, broadcast
packets, and multicast packets) received.
