Summary of iPCA Configuration Tasks

As shown Figure 1, employees in the enterprise branch and headquarters are participating in a video conference.

Table 1 lists the iPCA scenarios and corresponding configurations.

**Table 1** iPCA configuration tasks
Scenario	Description	Task
Employees participating in the conference encounter erratic display and voice delay. The network administrator wants to monitor packet loss on the network.	Configure end-to-end packet loss measurement on interface C1 of core switch S2 and interface C2 of core switch S5, to monitor network quality.	Configuring iPCA to Implement Network-Level Packet Loss Measurement
The network administrator considers that packet loss occurs on the WAN and cause network quality to degrade. Therefore, the administrator wants to diagnose or monitor packet loss.	Configure regional network packet loss measurement between interface D1 of egress gateway S3 and interface D2 of egress gateway S4 to locate faults.	Configuring iPCA to Implement Network-Level Packet Loss Measurement
The network administrator discovers packet loss on the headquarters and enterprise branch networks, and wants to monitor or diagnose packet loss on the entire network for fault location.	Configure hop-by-hop packet loss measurement on interface A1 of switch S1 and interface A2 of switch S6 to show quality on each node through the MCP.	Configuring iPCA to Implement Network-Level Hop-by-Hop Packet Loss Measurement
The network administrator discovers packet loss on the headquarters and enterprise branch networks, and wants to locate the link where packets are lost.	Configure direct link packet loss measurement on all links, including the link between interface B1 of switch S1 and interface C1 of switch S2.	Configuring iPCA to Implement Packet Loss Measurement on a Direct Link
The network administrator wants to monitor packet loss on the core switches in real time.	Configure device packet loss measurement on core switch S2 or S5.	Configuring iPCA to Implement Packet Loss Measurement on a Device
