Chapter 12 Performance Monitoring

12.6.2 ASAP Card Ethernet Performance Monitoring Parameters

Table 12-6	ASAP Ethernet Statistics Parameters (continued)
Parameter		Meaning
etherStatsBroadcastPkts		The total number of good packets received that were directed to
		the broadcast address. Note that this does not include multicast
		packets.
etherStatsMulticastPkts		The total number of good packets received that were directed to
		a multicast address. Note that this number does not include
		packets directed to the broadcast address.
etherStatsFragments		The total number of packets received that were less than
		64 bytes in length (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).
		Note It is entirely normal for etherStatsFragments to
		increment. This is because it counts both runts (which
		are normal occurrences due to collisions) and noise hits.
etherStatsPkts64Octets		The total number of packets (including bad packets) received
		that were 64 bytes in length (excluding framing bits but
		including FCS bytes).
etherStatsPkts65to127Octets		The total number of packets (including bad packets) received
		that were between 65 and 127 bytes in length inclusive
		(excluding framing bits but including FCS bytes).
etherStatsPkts128to255Octets		The total number of packets (including bad packets) received
		that were between 128 and 255 bytes in length inclusive
		(excluding framing bits but including FCS bytes).
etherStatsPkts256to511Octets		The total number of packets (including bad packets) received
		that were between 256 and 511 bytes in length inclusive
		(excluding framing bits but including FCS bytes).
etherStatsPkts512to1023Octets		The total number of packets (including bad packets) received
		that were between 512 and 1023 bytes in length inclusive
		(excluding framing bits but including FCS bytes).
etherStatsPkts1024to1518Octets		The total number of packets (including bad packets) received
		that were between 1024 and 1518 bytes in length inclusive
		(excluding framing bits but including FCS bytes).
Rx Utilization		The percentage of receive (Rx) line bandwidth used by the
		Ethernet ports during consecutive time segments.
Tx Utilization		Same as Rx Utilization, except calculated over the transmit
		(Tx) line bandwidth.
Rx Alignment Errors		A count of frames received on a particular interface that are not
		an integral number of bytes in length and do not pass the FCS
		check.
Rx FCS Errors		A count of frames received on a particular interface that are an
		integral number of bytes in length but do not pass the FCS
		check.
