Receive Statistics
5 min Input Rate (bits/sec) The average number of bits per second transmitted in the last 5 minutes.
5 min Input Rate (packets/sec) The average number of packets per second transmitted in the last 5 minutes.
Time Since Last Input The number of hours, minutes, and seconds since the last packet was successfully
received by an interface. Knowing this time helps you determine the traffic load
on the interface and locate network problems.
Total Packets Input The total number of error-free packets received by the system.
Total Bytes Input The total number of bytes, including data and MAC encapsulation, received by the
system.
Broadcast Packets The total number of broadcast packet received by the interface.
Transmit Statistics
5 min Output Rate (bits/sec) The average number of bits transmitted per second in the last 5 minutes.
5 min Output Rate (packets/sec) The average number of packets transmitted per second in the last 5 minutes.
Time Since Last Output The number of hours, minutes, and seconds since the last packet was successfully
transmitted by the interface. Knowing this time helps you determine the traffic
load on the interface and locate network problems.
Total Packets Output The total number of messages transmitted by the system.
Total Bytes Output The total number of bytes, including data and MAC encapsulation, transmitted by
the system.
Error Statistics/Receive
Total Input Errors The total number of input-related errors that occurred, including runts, giants, no
buffer, CRC, frame, overrun, and ignored counts.
Overrun Errors The number of times the receiver hardware was unable to send received data to a
hardware buffer because the input rate exceeded the receiver's ability to process
the data.
Ignored Packets The number of received packets ignored by the interface because the interface
hardware ran low on internal buffers. Broadcast storms and bursts of noise can
cause the ignored count to be increased.
Framing Errors The number of packets received incorrectly having a CRC error and non-integer
number of octets. These errors occur on a LAN as a result of a collision or
malfunctioning Ethernet device.
CRC Errors Cyclic redundancy checksum generated by the originating LAN station or far-end
device that does not match the checksum calculated from the data received.
These errors indicate noise or transmission problems on the LAN interface or LAN
bus itself. A high number of CRC errors usually results in collisions or the
transmission of bad data.
Packet too Short (Runts) The number of packets that are discarded because they are smaller than the
medium's minimum packet size. For example, any Ethernet packet that is less
than 64 bytes is considered a runt.
Packet too Long (Giants) The number of packets that are discarded because they exceed the medium's
maximum packet size. For example, any Ethernet packet that is greater than
1,518 bytes is considered a giant.
Throttles The number of times the receiver on the port was disabled, possibly due to buffer
or processor overload.
Error Statistics/Transmit
Total Output Errors The sum of all errors that prevented the final transmission of datagrams from
being examined.
Underrun Errors The number of times the transmitter has run faster than the router can handle.
Deferred Packets The number of packets deferred for an excessive period of time.
