Field
|
Description
|
|
Hardware
|
Provides the hardware type, followed by the hardware address.
|
|
Internet address
|
IP address of the interface.
|
|
MTU
|
Maximum packet size, in bytes, that a particular interface can handle.
|
|
Encapsulation
|
Encapsulation method assigned to the interface.
|
|
Mode
|
Indicates the operating mode of the interface, followed by transmission data.
|
|
packets input
|
Total number of packets received.
|
|
bytes
|
Total number of bytes, including data and MAC encapsulation, in the error-free packets received by the system.
|
|
total input drops
|
Total number of packets dropped from the input queue because the queue was full.
|
|
packets discarded in garbage collection
|
Number of packets and bytes discarded.
|
|
packets discarded in recv processing
|
Number of packets and bytes discarded.
|
|
Received broadcast packets and multicast packets
|
Indicates the total number of broadcast and multicast packets received by the interface.
|
|
Input errors
|
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.
|
|
packets output
|
Total number of messages transmitted by the system.
|
|
bytes
|
Total number of bytes, including data and MAC encapsulation, in the error-free packets transmitted by the system.
|
|
total output drops
|
Total number of packets dropped from the output queue because the queue was full.
|
|
Output
|
Indicates the total number of broadcast and multicast packets transmitted by the interface.
|
|
Output errors
|
Displays the number of errors transmitted on the interface. Output errors occur when outgoing cells are dropped or corrupted.
The possible types output errors are as follows:
-
underruns—Number of times that the far-end transmitter has been running faster than the near-end receiver can handle.
-
terminations—Number of illegal sequences of one bits on the interface.
-
loss of carrier—Number of times the interface was reset because the carrier detect line of that interface was up, but the
line protocol was down.
