l
Drop Events—Indicates the number of dropped packets due to lack of network resources during the sampling interval. This may not represent the

exact number of dropped packets, but rather the number of times dropped packets were detected.
Received Bytes (Octets)—Indicates the number of data octets, including bad packets, received on the network.
l
Received Packets—Indicates the number of packets received during the sampling interval.
l
Broadcast Packets—Indicates the number of good broadcast packets received during the sampling interval.
l
Multicast Packets—Indicates the number of good multicast packets received during the sampling interval.
l
CRC Align Errors—Indicates the number of packets received during the sampling session with a length 64-1518 octets.that have a bad Frame Check
l
Sequence (FCS) with an integral number of octets or a bad FCS with a non-integral number.
Undersized Packets—Indicates the number of packets received that are less than 64 octets long during the sampling session.
l
Oversized Packets—Indicates the number of packets received that are more than 1518 octets long during the sampling session.
l
Fragments—Indicates the number of packets received that are less than 64 octets long and have a FCS during the sampling session.
l
Jabbers—Indicates the number of packets received that are more than 1518 octets long and had a FCS during the sampling session.
l
Collisions—Estimates the total number of packet collisions that occurred during the sampling session. Collisions are detected when repeater ports
l
detect two or more stations transmitting simultaneously.
Utilization—Estimates the main physical layer network Description on an interface during the session sampling. The value is reflected in percentages
l
with two decimal places.
