Solution 2377089.1 : Eagle: Why does Eagle generates duplicate alarm traps for " DPC prohibited alarm ( UAM 313 ) " for same DPC intermittently.

Applies to:

Oracle Communications EAGLE (Hardware) - Version EAGLE 46.0 and later
Information in this document applies to any platform.

Goal

To explain the cause of generating DPC prohibited alarm (UAM 313) multiple times for same DPC intermittently

****18-01-17 15:57:18****
0176.0313 *C DPC s-XXXX DPC is prohibited

****18-01-17 15:57:18****
0178.0313 *C DPC s-XXXX DPC is prohibited

****18-01-17 15:57:18****
0176.0313 *C DPC s-XXXX DPC is prohibited
****18-01-17 15:57:18****
0177.0236 ** SLK 1212,B REPT-LKF: not aligned
****18-01-17 15:57:18****
0178.0313 *C DPC s-XXXX DPC is prohibited

Solution

DPC’s with SSN Subsystem configured produce “ DPC is Prohibited “ alarms two times.

1. 1st DPC prohibited is for linkset.
2. 2nd DPC prohibited is with SSN.

As UIM and UAM generated does not have alarm description , they only show one liner alarm information.

****18-01-17 15:57:18****
0176.0313 *C DPC s-XXXX DPC is prohibited

****18-01-17 15:57:18****
0178.0313 *C DPC s-XXXX DPC is prohibited

Terminal Logs help us to get alarm description , we can observe “ DPC is Prohibited “ alarm generates for both linkset and Subsystem Number ( SSN ).

*C 0178.0313 *C DPC s-XXXX DPC is prohibited
LSN=vharei02i3
Prohibited SS: 9

Conclusion - DPC's configured along with defined SSN will produce “DPC is Prohibited” alarm two times. one is for LSN and other will be for SSN defined for the node .
