J.4.8 ONS 15800, ONS 15801, or ONS 15808 NE Generates Too Many Alarms

J.4.8 ONS 15800, ONS 15801, or ONS 15808 NE Generates Too Many Alarms

Occasionally, ONS 15800, ONS 15801, and ONS 15808 NEs generate so many alarms that the CTM client cannot process all of them. Set the operational state of the NE to Under Maintenance while debugging the cause of the alarms:

Step 1 In the CTM Domain Explorer window, right-click the ONS 15800, ONS 15801, or ONS 15808 that is generating the large number of alarms and choose Mark Under Maintenance.

Step 2 Debug the ONS 15800, ONS 15801, or ONS 15808 NE to see which card is in error. Find the card that is generating the alarms and mark it as Under Maintenance.

Step 3 While the card is under maintenance for debugging, set the ONS 15800, ONS 15801, or ONS 15808 NE back to In Service.

J.4.9 Bandwidth-Intensive Operations Are Blocked

Bottlenecks in the DCN affect bandwidth-intensive operations, such as software download. Tune the timeout and retry values to match DCN performance. Log into the NE and enter the following commands:

•ip tftp min-timeout—Sets the minimum wait time, in seconds, before retrying the read/write request.

•ip tftp max-timeout—Sets the maximum wait time, in seconds, before retrying the read/write request.

•ip tftp backoff-delay—Sets the number of seconds to extend wait time if the read/write request times out.

•ip tftp write-retries—Sets the maximum number of times to retry the TFTP read/write request before declaring a failure.

J.4.10 NE Displays Incorrect Configuration Management Data

Step 1 In the Domain Explorer window, choose Administration > Service Monitor and verify that the NE Service is running. If it is not running, start the NE Service.

Step 2 Test NE connectivity.

a.In the Domain Explorer tree, select the NE and choose Fault > Test NE Connectivity. The message “<NE_name> (<IP_address>) is available” should be generated.

b.If the NE is unavailable, establish connectivity to the NE before retrieving configuration data.
