Usage Guidelines

Usage Scenario

An ACH comprises two target logical ports (TLPs) and identifies a range between two measurement points. To create an ACH for an IP FPM instance, run the ach command so that the target flow direction and measurement points can be configured for IP Forward Performance Monitoring (FPM) hop-by-hop performance statistics.

Prerequisites

The instance command has been run to configure an IP FPM instance on a measurement control point (MCP).

Example

# Create an ACH.

[~HUAWEI] nqa ipfpm mcp
[*HUAWEI-nqa-ipfpm-mcp] instance 1
