display twamp-light statistic-type test-session
Function
The display twamp-light statistic-type twoway-delay test-session command displays statistics about two-way packet delay of a TWAMP Light test session.
The display twamp-light statistic-type oneway-delay test-session command displays statistics about one-way packet delay of a TWAMP Light test session.
Parameters
| Parameter | Description | Value |
|---|---|---|
| session-id |
Specifies the ID of a test session. |
The value is an integer ranging from 1 to 2048. |
| link-bundle-member ifName |
Specifies the name of a link-bundle interface. |
- |
| ifType |
Specifies the type of a link-bundle interface. |
- |
| ifNum |
Specifies the number of a link-bundle interface. |
- |
| summary |
Displays brief delay statistics about a TWAMP trunk. |
- |
Usage Guidelines
Usage Scenario
To check statistics about two-way and one-way packet delay of a TWAMP Light test session, run the display twamp-light statistic-type twoway-delay test-session command or run the display twamp-light statistic-type oneway-delay test-session command.
- Sampled statistics of delay packets are calculated as average values within the sampling period.
- The accumulated statistics, in the maximum, minimum, and average forms, are unnecessarily the same as the sampled statistics.
Example
The actual command output varies according to the device. The command output here is only an example.
