Description
Encapsulation method assigned to the interface.
Indicates the operating mode of the interface, followed
by transmission data.
Total number of packets received.
Total number of bytes, including data and MAC
encapsulation, in the error-free packets received by
the system.
Total number of packets dropped from the input queue
because the queue was full.
Number of packets and bytes discarded.
Number of packets and bytes discarded.
Indicates the total number of broadcast and multicast
packets received by the interface.
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.
Total number of messages transmitted by the system.
Total number of bytes, including data and MAC
encapsulation, in the error-free packets transmitted
by the system.
