Usage Guidelines

Usage Scenario

To check the number of discarded packets of an IP FPM instance, run the display ipfpm statistic-type loss instance command. To locate and diagnose network faults when network performance deteriorates, run the display ipfpm statistic-type loss instance command with ach configured to check statistics for a specified ACH.

Precautions

This command is valid only on MCPs.

The first statistics collected may not be accurate, therefore, using subsequent statistics as a reference for network performance is recommended.

Example

The actual command output varies according to the device. The command output here is only an example.

# Display the packet loss statistics for IP FPM instance 1 on an MCP.
