RMON Statistics
Drop Events The total number of events in which packets 
were dropped due to lack of resources.
Jabbers The total number of frames received that were 
longer than 1518 octets (excluding framing bits, 
but including FCS octets), and had either an FCS 
or alignment error.
Received Bytes Total number of bytes of data received on the 
network. This statistic can be used as a 
reasonable indication of Ethernet utilization.
Collisions The best estimate of the total number of 
collisions on this Ethernet segment.
Received Frames The total number of frames (bad, broadcast and 
multicast) received.
Broadcast Frames The total number of good frames received that 
were directed to the broadcast address. Note that 
this does not include multicast packets.
Multicast Frames The total number of good frames received that 
were directed to this multicast address.
CRC/Alignment Errors The number of CRC/alignment errors (FCS or 
alignment errors). 
Undersize Frames The total number of frames received that were 
less than 64 octets long (excluding framing bits, 
but including FCS octets) and were otherwise 
well formed.
Oversize Frames The total number of frames received that were 
longer than 1518 octets (excluding framing bits, 
but including FCS octets) and were otherwise 
well formed. 
Fragments The total number of frames received that were 
less than 64 octets in length (excluding framing 
bits, but including FCS octets) and had either an 
FCS or alignment error.
