Reachability Unknown Status for several devices


Article ID: 241078


Updated On:


CA Performance Management - Usage and Administration DX NetOps


The devices are active and responding to SNMP polls and Ping.

We reviewed the following KB article but it did not help:

Is there another reason this is happening?


The devices are managed by NFA and DA:

mysql> select a.SourceID, a.itemname, a.LocalID, a.ItemID, v6_ntoa(a.Address), b.consolename from dst_device a, data_sources2 b where a.sourceid=b.sourceid and v6_ntoa(a.Address) = '10.xx.yy.zz';


The PC is failing to communicate to the NFA data source.

In the ../PerformanceCenter/DM/logs/DMService.log file:

java.util.concurrent.ExecutionException: Unexpected error occurred while scanning a RIB source
  RIB Source URL: https://<NFA_hostname>:8681/NFARS/ribsource/rib/soap?wsdl

Caused by: SSLException invoking https://<NFA_hostname>:8681/NFARS/ribsource/rib/soap?wsdl: Unrecognized SSL message, plaintext connection?


Release : 20.2

Component : Performance Management NFA Integration


Temporarily set HTTP/80 on the NFA data source until the SSL certificate issue is fixed.
