Multicasts (Read-only)
The Multicasts field displays the total number of good frames received 
that were directed to a multicast address. The value of this field does not 
include frames directed to the broadcast address.
CRC Align Errors (Read-only)
This field displays the number of frames with bad Cyclic Redundancy 
Checks (CRC) received from the network. The CRC is a 4-byte field in 
the data frames that ensures that the data received is the same as the data 
that was originally sent. 
Undersized Pkts (Read-only)
The Undersized Pkts field displays the number of frames received whose 
size was less than the minimum Ethernet frame size of 64 bytes, not 
including preamble, but have a valid CRC.
Oversized Pkts (Read-only)
The Oversized Pkts field displays the number of frames received whose 
size exceeded 1518 data bytes, not including preamble, but have a valid 
CRC.
Fragments (Read-only)
This field displays the number of received frames that are not the 
minimum number of bytes in length or received frames that had a bad 
Frame Check Sequence (FCS), were less than 64 bytes in length 
(excluding framing bits, but including FCS bytes), and have an invalid 
CRC.
Jabbers (Read-only)
This field displays the total number of frames that were greater than 1518 
bytes and had either a bad FCS or a bad CRC.
Total Packets (Read-only)
This field displays the total number of frames (including bad frames, 
broadcast frames, and multicast frames) received on this interface.
It is normal for the Fragments field to increment. This is 
because the RMON agent increments the field when runts are 
detected (which are normal occurrences due to collisions) and 
when noise hits occur.
