packets input	Total number of packets received.
packets output	Total number of packets transmitted.
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. •aborts—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.

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. •aborts—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.
