5.3 Collecting IPv4 Traffic Statistics

This section describes how to collect statistics about IPv4 traffic passing through an interface.

5.3.1 Establishing the Configuration Task

Applicable Environment
To collect statistics about incoming and outgoing IPv4 packets on an interface, configure the
NetStream for IPv4 original traffic. The statistics are sent to the Network Management System
(NMS). By analyzing the traffic statistics, the NMS obtains the traffic information for you to
effectively manage the network.
Pre-configuration Tasks
Before configuring NetStream for IPv4 original traffic, complete the following tasks:

After the inactive aging time is set, the traffic is aged if the SPU does not receive any packet
of that traffic type in a certain period. Then the SPU stops the statistics collection and sends
the result to the NSC.
Aging depending on the active aging time:
After the active aging time is set, the SPU starts the aging timer when the first packet of
this traffic type is collected. When the timer expires, the traffic is aged. Then the SPU stops
the statistics collection and sends the result to the NSC.
Aging by the FIN or RST flag in the TCP packets:
If the traffic received by the SPU contains the TCP FIN or RST flag, the traffic is aged.
Then the SPU stops the statistics collection and sends the result to the NSC.
Aging depending on byte overflow
If the number of bytes in the statistics reaches a specified value, the traffic is aged. This
function is enabled by default.
