Description
Field
Maximum packet size, in bytes, that a particular
interface can handle.
MTU
Encapsulation method assigned to the interface.
Encapsulation
Indicates the operating mode of the interface, followed
by transmission data.
Mode
Total number of packets received.
packets input
Total number of bytes, including data and MAC
encapsulation, in the error-free packets received by
the system.
bytes
Total number of packets dropped from the input queue
because the queue was full.
total input drops
Number of packets and bytes discarded.
packets discarded in garbage collection
Number of packets and bytes discarded.
packets discarded in recv processing
Indicates the total number of broadcast and multicast
packets received by the interface.
Received broadcast packets and multicast packets
Displays the number of errors received by the
interface. Input errors occur when incoming cells are
dropped or corrupted. The possible input errors are
as follows:
•
CRC
—
Number of times that the checksum
calculated from the data received did not match
the checksum from the transmitted data.
•
overrun
—
Number of times that the receiver
hardware was incapable of handing received
data to a hardware buffer because the input rate
exceeded the receiver's capability to handle the
data.
•
alignment
—
Number of nonoctets received.
•
length
—
Number of times the interface
prevented the ASIC from overrunning a
maximum transmission unit (MTU) size.
•
collision
—
Number of messages retransmitted
because of an Ethernet collision.
Input errors
Total number of messages transmitted by the system.
