Octets
|
The total number of octets of data (including those in bad packets) received on the network (excluding framing bits but including FCS octets). This object can be used as a reasonable estimate of Ethernet utilization. For greater precision, sample the etherStatsPkts and etherStatsOctets objects before and after a common interval.
|
Pkts
|
The total number of packets (including bad packets, broadcast packets, and multicast packets) received.
|
BroadcastPkts
|
The total number of good packets received that were directed to the broadcast address. Note that this number does not include multicast packets.
|
MulticastPkts
|
The total number of good packets received that were directed to the multicast address. Note that this number does not include packets directed to the broadcast address.
|
CRCAlignErrors
|
The total number of packets received that had a length (excluding framing bits but including FCS octets) of between 64 and 1518 octets inclusive, but had either a bad Frame Check Sequence (FCS) with an integral number of octets (FCS Error) or a bad FCS with a nonintegral number of octets (Alignment Error).
|
UndersizePkts
|
The total number of packets received that were less than 64 octets long (excluding framing bits but including FCS octets) and were otherwise well formed.
|
OversizePkts
|
The total number of packets received that were more than 1518 octets long (excluding framing bits but including FCS octets) and were otherwise well formed.
|
Fragments
|
The total number of packets received that were less than 64 octets long (excluding framing bits but including FCS octets) and had either a bad Frame Check Sequence (FCS) with an integral number of octets (FCS Error) or a bad FCS with a nonintegral number of octets (Alignment Error). It is entirely normal for etherStatsFragments to increment because it counts both runts (which are normal occurrences due to collisions) and noise hits.
|
Collisions
|
The best estimate of the total number of collisions on this Ethernet segment.
