•
Drop Events
— Displays the total number of events in which packets were dropped by the port due to
lack of resources. Note that this number is not necessarily the number of packets dropped; it is just the
number of times this condition has been detected.
•
Received Bytes (Octets)
— Displays the total number of octets of data (including those in bad
packets) received on the network (excluding framing bits but including Frame Check Sequence (FCS)
octets).
•
Received Packets
— Displays the total number of packets received (including bad packets, broadcast
packets, and multicast packets) during the sampling interval.
•
Broadcast Packets
— Displays the total number of good packets received that were directed to the
broadcast address. Note that this does not include multicast packets.
•
Multicast Packets
— Displays the total number of good packets received that were directed to a
multicast address. Note that this number does not include packets directed to the broadcast address.
•
CRC Align Errors
— Displays 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
FCS with an integral number of octets, (FCS Error) or a bad FCS with a non-integral number of octets
(Alignment Error).
•
Undersize Packets
— Displays 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.
•
Oversize Packets
— Displays the total number of packets received that were longer than 1518 octets
(excluding framing bits, but including FCS octets) and were otherwise well formed.
•
Fragments
— Displays the total number of packets received that were less than 64 octets in length
(excluding framing bits but including (FCS) with an integral number of octets (FCS Error) or a bad
FCS with a non-integral number of octets (Alignment Error).
•
Jabbers
— Displays the total number of packets received that were longer than 1518 octets (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 non-integral number of octets (Alignment
Error).
•
Collisions
— Displays the best estimate of the total number of collisions on this Ethernet segment.
•
Utilization
— Estimates the main physical layer network usage on an interface during the session
sampling. The value is reflected hundredths of percent.
