Channel... is up

Indicates whether the interface hardware is active (whether synchronization is achieved on an ESCON channel, or whether operational out is enabled on a parallel channel) and whether it has been taken down by an administrator.

line protocol is up

Indicates whether the software processes that handle the line protocol "think" the line is usable (that is, whether keepalives are successful).

Hardware is

Hardware type.

Internet address is

IP address and subnet mask.

MTU

Maximum transmission unit of the interface.

BW

Bandwidth of the interface in kilobits per second.

DLY

Delay of the interface in microseconds.

load

Load on the interface as a fraction of 255 (255/255 is completely saturated), calculated as an exponential average over 5 minutes. The calculation uses the value from the bandwidth interface configuration command.

Encapsulation

Indicates whether loopbacks are set.

keepalive

Indicates whether keepalives are set.

daughter card

Type of adapter card.

Data transfer rate

Rate of data transfer.

Number of subchannels

Number of subchannels.

Last input

Number of hours, minutes, and seconds since the last packet was successfully received by an interface. Useful for knowing when a dead interface first failed. This counter is updated only when packets are process switched, not when packets are fast switched.

Last output

Number of hours, minutes, and seconds since the last packet was successfully sent by an interface. This counter is updated only when packets are process switched, not when packets are fast switched.

output hang

Number of hours, minutes, and seconds (or never) since the interface was last reset because of data that took too long to send. When the number of hours in any of the "last" fields exceeds 24 hours, the number of days and hours is printed. If that field overflows, asterisks are printed.

Last clearing

The time at which the counters that measure cumulative statistics (such as number of bytes sent and received) shown in this report were last reset to zero. Note that variables that might affect routing (for example, load and reliability) are not cleared when the counters are cleared. These asterisks (***) indicate the elapsed time is too large to be displayed; 0:00:00 indicates the counters were cleared more than 231ms (and less than 232ms) ago.

Output queue, drops input queue, drops

Number of packets in output and input queues. Each number is followed by a slash, the maximum size of the queue, and the number of packets dropped due to a full queue.

Five minute input rate, Five minute output rate

Average number of bits and packets sent per second in the last five minutes.

packets input

Total number of error-free packets received by the system.

bytes input

Total number of bytes, including data and MAC encapsulation, in the error-free packets received by the system.

no buffer

Number of received packets discarded because there was no buffer space in the main system. Compare with ignored count. Broadcast storms on Ethernets and bursts of noise on serial lines are often responsible for no input buffer events.

broadcasts

Total number of broadcast or multicast packets received by the interface.

runts

Number of packets that are discarded because they are smaller than the medium's minimum packet size.

giants

Number of packets that are discarded because they exceed the medium's maximum packet size.

input errors

Total number of buffer, runts, giants, cyclic redundancy checks (CRC), frame, overrun, ignored, and abort counts. Other input-related errors can also increment the count, so that this sum may not balance with the other counts.

CRC

Number of code violation errors seen on the ESCON interface, where a received transmission character is recognized as invalid. On a parallel interface, the number of parity errors seen.

frame

Number of received packets having an incorrect CRC error and a noninteger number of octets. This value is always 0.

overrun

Number of times the serial receiver hardware was unable to hand received data to a hardware buffer because the input rate exceeded the receiver's ability to handle the data. This value is always 0.

ignored

Number of received packets ignored by the interface because the interface hardware ran low on internal buffers. These buffers are different than the system buffers mentioned previously in the "no buffer" description. Broadcast storms and bursts of noise can cause the ignored count to be increased.

abort

Illegal sequence of one bits on a serial interface. This usually indicates a clocking problem between the serial interface and the data-link equipment. This value is always 0.

packets output

Total number of messages sent by the system.

bytes

Total number of bytes, including data and MAC encapsulation, sent by the system.

underruns

Sum of all errors that prevented the final sending of datagrams out of the interface being examined. Note that this may not balance with the sum of the enumerated output errors, because some datagrams may have more than one error, and others may have errors that do not fall into any of the specifically tabulated categories.

output errors

Number of output errors.

collisions

Number of collisions detected. This value is always 0.

interface resets

Number of times an interface has been completely reset. This can happen if packets queued for sending were not sent within several seconds. On a serial line, this can be caused by a malfunctioning modem that is not supplying the send clock signal, or by a cable problem. If the system notices that the carrier detect line of a serial interface is up, but the line protocol is down, it periodically resets the interface in an effort to restart it. Interface resets can also occur when an interface is looped back or shut down.

On the CMCC adapter, this may occur if the host software is not requesting data.

restarts

Number of times the controller was restarted because of errors.

Functional Address

output hang

Number of hours, minutes, and seconds (or never) since the interface was last reset because the data took too long to send. When the number of hours in any of the "last" fields exceeds 24 hours, the number of days and hours is printed. If that field overflows, asterisks are printed.

overrun

Number of times the serial receiver hardware was unable to hand received data to a hardware buffer because the input rate exceeded the receiver's ability to handle the data.

underruns

Number of times that the far-end sender has been running faster than the near-end router's receiver can handle. This may never be reported on some interfaces.

output errors

Sum of all errors that prevented the final sending of datagrams out of the interface being examined. Note that this may not balance with the sum of the enumerated output errors, because some datagrams may have more than one error, and others may have errors that do not fall into any of the specifically tabulated categories.

collisions

Because a Token Ring cannot have collisions, this statistic is nonzero only if an unusual event occurred when frames were being queued or dequeued by the system software.

Number of times an interface has been reset. The interface may be reset by the administrator or automatically when an internal error occurs.

restarts

Should always be zero for Token Ring interfaces.

transitions
