The show interfaces GigabitEthernet statistics rmon command displays the following information:
| Output field | Description | 
|---|---|
| PORT NUM | Indicates the port number. | 
| OCTETS | The total number of octets of data (including those in bad packets) received on the network (excluding framing bits but including FCS octets). | 
| PKTS | The total number of packets (including bad packets, broadcast packets, and multicast packets) received. | 
| MULTICAST | The total number of packets received that were directed to a multicast address. This number does not include packets directed to the broadcast address. | 
| BROADCAST | The total number of packets received that were directed to the broadcast address. This number does not include multicast packets. | 
| CRC ALLIGN | The total number of packets received that had a length (excluding framing bits, but including FCS octets) between 64 and 1518 octets, inclusive, but had either a bad Frame Check Sequence (FCS) with an integral number of octets (FCS Error), or a bad FCS with a nonintegral number of octets (Alignment Error). | 
| UNDERSIZE | The total number of packets received that were less than 64 octets long (excluding framing bits, but including FCS octets) and were otherwise well formed. | 
| OVERSIZE | The total number of packets received that were longer than 1518 octets (excluding framing bits, but including FCS octets) and were otherwise well formed. | 
| FRAGMENT | The total number of packets received that were less than 64 octets in length (excluding framing bits but including FCS octets) and had either a bad Frame Check Sequence (FCS) with an integral number of octets (FCS Error) or a bad FCS with a nonintegral number of octets (Alignment Error). | 
| COLLISION | An estimated value for the total number of collisions on this Ethernet segment. |
