From this dialog box, you can monitor the drop statistics for protocol packet transmissions.
Right-click the port and then select Monitor > Packet Trans - Dropped.
In Framing (cieIfInFramingErrs)
In Overrun (cieIfInOverrunErrs)
Input Queue (cieIfInputQueueDrops)
Output Queue (cieIfOutputQueueDrops)
Note: Discontinuities in the value of these objects can occur at reinitialization of the management system, and at other times as indicated by the values of cieIfPacketDiscontinuityTime.
Number of input packets on a physical interface which were dropped because they were smaller than the minimum allowable physical media limit.
Number of input packets on a physical interface which were dropped because they were larger than ifMtu (the largest permitted size of a packet which can be sent/received by an interface).
Number of input packets on a physical interface which were misaligned or had framing errors. This happens when the format of the incoming packet is incorrect.
Number of input packets on a physical interface which were too quick for the hardware to receive, resulting in the receiver running out of buffers.
Number of input packets which were ignored by the physical interface due to a lack of sufficient resources for handling incoming packets.
This may indicate that the input receive buffers are not available or that the receiver has lost a packet.
Number of input packets which were dropped because the receiver aborted.
Number of input packets which were dropped. Some reasons why this object could be incremented are:
The input queue is full.
Errors were detected at the receiver hardware while receiving the packet.
Number of output packets dropped by the interface even though no error had been detected to prevent their transmission.
A packet can be dropped for many reasons, such as the interface being down and the presence of errors in the packet format.
