Usage Guidelines

Usage Scenario

An ACH consists of two target logical ports (TLPs) and is used to identify a segment between two specified devices on the network. In IP FPM hop-by-hop measurement, you need to specify the ACH for the target flow in a measurement instance and configure the direction and measurement points for the target flow in the ACH view. You can create an ACH and enter the ACH view by running the ach command.

Prerequisites

The instance command has been run to configure an IP FPM instance on an MCP.

Example

# Create an ACH.

<HUAWEI> system-view
[HUAWEI] nqa ipfpm mcp
[HUAWEI-nqa-ipfpm-mcp] instance 1
[HUAWEI-nqa-ipfpm-mcp-instance-1] ach 1
