The display ipfpm statistic-type command displays performance statistics for an IP Flow Performance Measurement (IP FPM) instance.
display ipfpm statistic-type oneway-delay instance instance-id [ ach ach-id ]
display ipfpm statistic-type twoway-delay instance instance-id [ ach ach-id ]
display ipfpm statistic-type oneway-delay instance instance-id [ ach ach-id ] verbose
display ipfpm statistic-type twoway-delay instance instance-id [ ach ach-id ] verbose
| Parameter | Description | Value |
|---|---|---|
| ach ach-id |
Displays hop-by-hop performance statistics for an ACH. |
The value is an integer ranging from 1 to 2147483647. |
| twoway-delay |
Displays two-way delay statistics. |
- |
| instance instance-id |
Specifies an IP FPM instance ID. |
The value is an integer ranging from 1 to 8355838. |
| oneway-delay |
Displays one-way delay statistics. |
- |
| verbose |
Displays detailed one-way or two-way delay statistics. |
- |
Usage Scenario
To check the number of discarded packets, packet loss rate, one-way and two-way delay statistics, and jitter of an IP FPM instance, run the display ipfpm statistic-type command. To locate and diagnose network faults when network performance deteriorates, run the display ipfpm statistic-type 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.
The actual command output varies according to the device. The command output here is only an example.
