RMON History Overview:
History Index: Display Index of History control entry.
Sample Index: Display Index of the data entry associated with the control entry.
Sample Start: The time at which this sample started, expressed in seconds since the switch booted up.
Drop: The total number of dropped packets due to lack of resources.
Octets: The total number of octets of data received.
Pkts: The total number of packets (including bad packets, broadcast packets) received.
Broadcast: The total number of good packets received that were directed to the broadcast address.
Multicast: The total number of good packets received that were directed to a multicast address.
CRC Errors: The total number of packets received that had a length (excluding framing bits, but including FCS
octets) of between 64 and 1518 octets.
Undersize: The total number of packets received that were less than 64 octets.
Oversize: The total number of packets received that were longer than 1518 octets.
Frag.: The number of frames which size is less than 64 octets received with invalid CRC.
