HH3C-TWAMP-MIB

About this MIB

Use HH3C-TWAMP-MIB to implement NQA TWAMP Light as follows:

·     Enable the TWAMP Light client and the TWAMP Light sender.

·     Configure and obtain information about test sessions on the TWAMP Light client.

·     Configure and obtain packet sending intervals, timeout time of the reflected packet, and statistics collection interval for TWAMP Light tests on the TWAMP Light sender.

·     Obtain the TWAMP Light sender status.

·     Obtain two-way delay and two-way jitter statistics for TWAMP Light tests on the TWAMP Light sender.

Notifications

hh3cTwampTwoWayLossExceed

Basic information

OID	Event	Type	Severity	Recovery notification	Default status
1.3.6.1.4.1.25506.2.184.1.0.1	The two-way packet loss ratio exceeds the upper threshold.	Error	Warning	1.3.6.1.4.1.25506.2.184.1.0.2( hh3cTwampTwoWayLossRecover)	OFF

 

Notification triggers

This notification is generated when the two-way packet loss ratio exceeds the upper threshold in the TWAMP test. Possible causes might include the following:

1.     Cause 1: Network congestion due to abnormal traffic.

2.     Cause 2: Unstable link state.

System impact

The packet loss rate is too high and might not meet the service requirements. Services are affected.

Status control

ON

CLI: Use the reaction item-number checked-element two-way-loss threshold-value upper-threshold lower-threshold action-type trap-only command.

OFF

CLI: Use the undo reaction item-number command.

Notification triggers

This notification is generated when the number of TWAMP test sessions reaches the upper limit.

System impact

The TWAMP test sessions that exceed the system capacity cannot operate correctly.

Status control

This notification cannot be disabled.

Objects

None.

Recommended action

To resolve this issue:

1.     Execute the display nqa twamp-light client verbose command to check for inactive sessions.

¡     If inactive sessions exist, delete the sessions.

¡     If no inactive sessions exist, as a best practice, arrange services appropriately.

2.     If the issue persists, collect alarm information and configuration data, and then contact H3C Support for help.

hh3cTwampSenderStartFailure

Basic information

OID	Event	Type	Severity	Recovery notification	Default status
1.3.6.1.4.1.25506.2.184.1.0.9	The TWAMP test session failed to start.	Informational	Major	N/A	OFF

 

Notification triggers

This notification is generated when the TWAMP test session fails to start.

Possible reasons for generating this notification include:

·     The timestamp format is set to NTP for probe packets in the TWAMP test, and the packet sending interval is set to 10 milliseconds or 100 milliseconds. Configuration conflict occurs.

·     Hardware resource insufficiency.

System impact

The test session cannot operate correctly on the TWAMP sender.

Status control

This notification cannot be disabled.

Recommended action

1.     Use the display nqa twamp-light client verbose command to view detailed information about all test sessions. Use the start command to edit the packet sending interval. Alternatively, use the timestamp-format command to change the timestamp format. Then restart the test session.

¡     If the test session starts successfully, the issue is resolved.

¡     If the test session fails to start, proceed to step 2.

2.     Collect alarm information and configuration data, and then contact H3C Support for help.

Recommended action

1.     Use the display nqa twamp-light responder command to check the reflected packet settings.

2.     Use the test-session command to configure the parameters required for the current network, and then restart the test session.

¡     If the test session starts successfully, the issue is resolved.

¡     If the test session fails to start, proceed to step 3.

3.     Collect alarm information and configuration data, and then contact H3C Support for help.
