Configuring iPCA to Implement Network-Level Packet Loss Measurement

Configuring iPCA to Implement Network-Level Packet Loss Measurement

Context

After network-level packet loss measurement is configured on a device, iPCA can measure the number of lost packets and packet loss ratio on the entire network.

In Figure 5-16, the target flow enters the network through Switch_1 and Switch_2, and leaves the network through Switch_3. To monitor packet loss on the network in real time, configure the packet loss function on the switches (Switch_1, Switch_2, and Switch_3) where the target flow enters and leaves as DCPs. Switch_1 has a relatively high performance, so it is selected as the MCP to summarize and calculate all statistics sent from DCPs, and report measurement results to user terminals or NMS.

Pre-configuration Tasks

Before configuring iPCA to implement network-level packet loss measurement, complete the following tasks:

  • Configure static routes or routing protocols to ensure network connectivity between devices. For details, see S12700 V200R011C10 Configuration Guide - IP Unicast Routing.
  • Configure NTP to implement time synchronization between the devices. For details, see NTP Configuration in the S12700 V200R011C10 Configuration Guide - Device Management.

Configuration Procedure

Configuring the DCP and Configuring the MCP can be configured in any sequence. The parameter settings on MCP and DCPs must be the same.
