Failure when adding a node with SNMPv3.

SNMP Walk on SNMPv3 devices is also failing.



​All NPM versions


The Access List (ACL) for network devices is not updated with the new IP address/es.


  1. Verify that the access list for the network devices have all the updated IP addresses. 
    Note: If the IP address are not updated, you will not be able to authenticate SNMPv3 or execute an SNMP Walk.
