show services monitoring pblq
Syntax
show services monitoring pblq (capabilities | summary | test-id test-id)
Description
Show the results of a packet-based link qualification (PBLQ) test. A PBLQ test checks the reliability of a link.
Options
| capabilities | Show the capabilities of the devices involved in the PBLQ test. The results of fields that measure duration are displayed in seconds. |
| summary | Show a summary of the currently running and completed PBLQ tests. |
| test-id test-id | Display the configuration and results of the PBLQ test that has the test ID you specify. The results of fields that measure duration are displayed in milliseconds. |
Required Privilege Level

Output Fields
show services monitoring pblq capabilities
The results of fields that measure duration are displayed in seconds.
| NTP synched | Whether the clock is synched with NTP. |
| Max result stored | The maximum number of test results that the device is capable of storing. |
Injector Capabilities
When the near device is in injector mode, these fields display the capabilities of the near device.
| Injector Minimum Sample Interval | The minimum interval that the device samples and updates the statistics related to the test. |
Generator Capabilities
When the near device is in injector mode, these fields are not applicable and are always 0.
Reflector Capabilities
These fields display the capabilities of the far device, which reflects the packets back to the near device. If the minimum duration of a stage of the test is lower than the minimum shown in the results of this RPC, the test fails.
| PMD Reflector Minimum Setup Duration | Not applicable. Always 0. |
| PMD Reflector Minimum Teardown Duration | Not applicable. Always 0. |
| ASIC Reflector Minimum Setup Duration | When the reflector is in ASIC mode, the minimum time the device requires to set up the test. |
| ASIC Reflector Minimum Teardown Duration | When the reflector is in ASIC mode, the minimum time it takes the device to return the interface to pre-test status. |
show services monitoring test-id test-id
The results of fields that measure duration are displayed in milliseconds.
Test Config
| Test ID | The identification number of the test. |
| Role | The supported role(s) of the device you run the command on. Use the desired role when setting up the PBLQ test. For the near device, the role should be INJECTOR. For the far device, the role should be REFLECTOR. |
Test Result
| Pre-Sync Duration | The remote setup time. After this completes, the reflector is ready to receive packets. |
| Setup Duration | The minimum time it takes the devices to set up the PBLQ test. |
| Qualification Duration | Length of the PBLQ test. |
| Post-Sync Duration | How long the near device should hold up the link until the far device finishes teardown. |
| Teardown Duration | The minimum time it takes the device to end the test and return the interface to its pre-test state. |
| Packet Count | Number of packets sent during the PBLQ test. |
| Packet Rate (Bps) | Not applicable. Always 0. |
| Packet Size | Size of each packet sent during the PBLQ test in bytes. This size must be greater than the minimum MTU and less than the maximum MTU. |
| Expected Rate (Bps) | Not applicable. Always 0. |
