Number of flows summarized by the aggregated record

Number of bytes summarized by this aggregated record, number of packets summarized by this 
aggregation record

Source and destination interface

Starting and ending time stamps

This aggregation scheme is particularly useful for generating autonomous system-to-autonomous system 
traffic flow data, and for providing substantial NetFlow Export data volume reduction. Figure 2 displays 
the AS-ToS aggregation export record format and a list follows describing the data.

Flows: Number of main cache flows that were aggregated.

Packets: Number of packets in the aggregated flows.

Bytes: Number of bytes in the aggregated flows.

First: Sys up time at which the first packet was switched.

Last: Sys up time at which the last packet was switched.

Source AS: autonomous system of the source IP address (peer or origin).

Destination AS: autonomous system of the destination IP address (peer or origin).

Source Interface: SNMP index of the interface the packets arrived on.

Destination Interface: SNMP index of the interface the packets went out.

ToS: Type of service byte.

Pad: Zero field.

Reserved: Zero field.
