    Note: The preceding log excerpts are only examples. Date, time, and environmental variables may vary depending on your environment.

 

Environment

Aria Operations for Networks 6.10.0
Aria Operations for Networks 6.11.0
Aria Operations for Networks 6.12.0
Aria Operations for Networks 6.12.1
Aria Operations for Networks 6.13.0
Aria Operations for Networks 6.14.0

Cause


In SNMP v3, each device must be configured unique engine_id. Two devices can not be configured with same engine_id.

Resolution

Re-check engine_id configured or reconfigure new engine_id with help of switch vendor.
 

Workaround:

This issue sometimes also occurs when a device is added and removed then added again with different IP or FQDN.

In such case there is work around, restart collector.



Additional Information

Impact/Risks:

Users will be unable to add switch to Aria Operations for Networks GUI.
