7.3 Collecting the Statistics of IPv4 Unicast Original Traffic

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

7.3.1 Establishing the Configuration Task

Before configuring the IPv4 unicast traffic statistics collection, familiarize yourself with the
applicable environment, complete the pre-configuration tasks, and obtain the data required for
the configuration. This will help you complete the configuration task quickly and accurately.
Applicable Environment
You need to configure the NetStream on an interface to collect statistics about inbound and
outbound IPv4 unicast packets respectively. The statistics result is sent to the Network
Management System (NMS). By analyzing the traffic statistics, the NMS can obtain the traffic
situation on the network and thus performs effective network management.
Pre-configuration Tasks
Before configuring the statistics about the IPv4 unicast original traffic, complete the following
tasks:

Data Preparation
To collect the statistics of the IPv4 unicast original traffic, you need the following data.

The inactive time indicates the interval between the time the last packet arrives and the
current time. When the inactive time expires, the system ages the traffic immediately.
Timeout aging of the active time
The active time indicates the interval from the time the first packet arrives to the current
time. After the traffic in the cache expires, the system ages the traffic in the cache.
Disconnection aging of the TCP connection
For a TCP connection, when the packets containing the FIN or RST flag are sent and the
flag is set, this indicates that a session is complete. When a packet containing the FIN or
RST flag is sampled from the existing TCP traffic, the system ages the corresponding traffic.
Overflow aging of the counting
When the load of traffic entering the cache exceeds the default, the system automatically
ages the traffic.
