RMON tab fields

Octets

The total number of octets of data (including those in bad packets) received on 

the network (excluding framing bits but including FCS octets). You can use this 

object as a reasonable estimate of Ethernet utilization. For greater precision, 

sample the etherStatsPkts and etherStatsOctets objects before and after a 

common interval. 

Packets

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).
