This command displays a summary of statistics for a specific interface or a count of all CPU traffic based upon the argument.
| Format | show interface {unit/slot/port | switchport | lag lag-id} |
| Mode | Privileged EXEC |
The display parameters, when the argument is unit/slot/port or lag lag-id, are as follows:
| Packets Received Without Error | The total number of packets (including broadcast packets and multicast packets) received by the processor. |
| Packets Received With Error | The number of inbound packets that contained errors preventing them from being deliverable to a higher-layer protocol. |
| Broadcast Packets Received | The total number of packets received that were directed to the broadcast address. Note that this does not include multicast packets. |
| Receive Packets Discarded | The number of inbound packets which were chosen to be discarded even though no errors had been detected to prevent their being deliverable to a higher-layer protocol. One possible reason for discarding such a packet could be to free up buffered space. |
| Packets Transmitted Without Error | The total number of packets transmitted out of the interface. |
| Transmit Packets Discarded | The number of outbound packets which were chosen to be discarded even though no errors had been detected to prevent their being deliverable to a higher-layer protocol. A possible reason for discarding a packet could be to free up buffer space. |
| Transmit Packets Errors | The number of outbound packets that could not be transmitted because of errors. |
| Collisions Frames | The best estimate of the total number of collisions on this Ethernet segment. |
| Load Interval | The length of time for which data is used to compute load statistics. The value is given in seconds, and must be a multiple of 30. The allowable range is from 30 to 600 seconds |
| Bits Per Second Received | Approximate number of bits per second received. This value is an exponentially weighted average and is affected by the configured load-interval. |
| Bits Per Second Transmitted. | Approximate number of bits per second transmitted. This value is an exponentially weighted average and is affected by the configured load-interval. |
| Packets Per Second Received | Approximate number of packets per second received. This value is an exponentially weighted average and is affected by the configured load-interval. |
| Packets Per Second Transmitted | Approximate number of packets per second transmitted. This value is an exponentially weighted average and is affected by the configured load-interval. |
| Percent Utilization Received | Value of link utilization in percentage representation for the RX line. |
| Percent Utilization Transmitted | Value of link utilization in percentage representation for the TX line. |
| Time Since Counters Last Cleared | The elapsed time, in days, hours, minutes, and seconds since the statistics for this port were last cleared. |
The display parameters, when the argument is “switchport” are as follows:
| Packets Received Without Error | The total number of packets (including broadcast packets and multicast packets) received by the processor. |
| Broadcast Packets Received | The total number of packets received that were directed to the broadcast address. Note that this does not include multicast packets. |
| Packets Received With Error | The number of inbound packets that contained errors preventing them from being deliverable to a higher-layer protocol. |
| Packets Transmitted Without Error | The total number of packets transmitted out of the interface. |
| Broadcast Packets Transmitted | The total number of packets that higher-level protocols requested to be transmitted to the Broadcast address, including those that were discarded or not sent. |
| Transmit Packet Errors | The number of outbound packets that could not be transmitted because of errors. |
| Time Since Counters Last Cleared | The elapsed time, in days, hours, minutes, and seconds since the statistics for this switch were last cleared. |
