How Do I Clear Alarms Generated by Unused Ports

Hello, friend!

In the Main Topology, double-click an optical NE icon to open the status diagram of the optical NE.  

Right-click a subrack NE and choose NE Explorer from the shortcut menu.  

Select the OTU board from the navigation tree and choose Configuration > WDM Interface > Basic Attributes > Settings > Channel Usage Status > Unused from the Function Tree.  

Click Apply.  

Check whether the alarm is cleared. 

Thanks!

In a DWDM system, when a client-side port is not in use but is set to the used state, alarms are reported on the NMS, such as ODU_AIS, SM_BDI, and MS_AIS alarms. These alarms may cause misunderstandings that services are interrupted.
Analysis:
In the main view, double-click the optical NE to display the status view. Specifically,
a. Right-click the NE in the subrack and choose NE Explorer from the short-cut menu. The NE Explorer is displayed.
b. Select the OTU board from the navigation tree. Choose Configuration > WDM Interface > Advanced Attributes.
c. Set the channel use stats to unused.d. Click Apply.
e. View alarms and check whether the alarm is cleared.
Root cause:
An alarm is generated when the NMS detects that an unused client-side or WDM-side port is set to the used state.
Answer:
Check the client-side optical port status of an OTU board to facilitate alarm analysis and troubleshooting. This operation must be performed with a prior approval and monitoring of the customer.
Suggestion and conclusion:
None

Hi,
In U2000 you can have several ways to clear alarms according to where u want to stop generating the alarm : -
1- u can make the channel unused to stop generating alarm in U2000 and in NE.
2- u can mask the alarm simply by making right click on the alarm then choose ( mask ). To stop generating alarm in U2000 side but u still can see alarms in the NE boards lamps .
3- u can supress the alarm simply by making right click on the alarm then choose ( supress NE alarm ). To stop generating alarm in side U2000 & NE sides .

Regards,
