This command displays the specified entry in the RMON history table.
| Format | show rmon history index {errors [period seconds] |throughput [period seconds] | other [period seconds]} |
| Mode | Privileged EXEC |
| Parameter | Description |
|---|---|
| alarm-index | An arbitrary integer index value used to uniquely identify the alarm entry. The range is 1 to 65535. |
| errors | Displays the error counters: CRC align errors, undersize and oversize packets, fragment packets, and jabber packets. |
| throughput | Displays the throughput counters: total number of octets, packets, successful broadcast and multicast packets, and port utilization. |
| other | Displays drop and collision counters. |
| periodseconds | The period of time, in seconds, for which to display history. This parameter is accepted for the errors, throughput, and other options. |
| Maximum Table Size | Maximum number of entries that the history table can hold. |
| Time | Time at which the sample is collected, displayed as period seconds. |
| CRC Align | Number of CRC align errors. |
| Undersize Packets | Total number of undersize packets. Packets are less than 64 octets long (excluding framing bits, including FCS octets). |
| Oversize Packets | Total number of oversize packets. Packets are longer than 1518 octets (excluding framing bits, including FCS octets). |
| Fragments | Total number of fragment packets. Packets are not an integral number of octets in length or had a bad Frame Check Sequence (FCS), and are less than 64 octets in length (excluding framing bits, including FCS octets). |
| Jabbers | Total number of jabber packets. Packets are longer than 1518 octets (excluding framing bits, including FCS octets), and are not an integral number of octets in length or had a bad Frame Check Sequence (FCS). |
| Octets | Total number of octets received on the interface. |
| Packets | Total number of packets received (including error packets) on the interface. |
| Broadcast | Total number of good Broadcast packets received on the interface. |
| Multicast | Total number of good Multicast packets received on the interface. |
| Util | Port utilization of the interface associated with the history index specified. |
| Dropped Collisions | Total number of dropped collisions. |
