How does Discovery choose IP when multiple SNMP IPs exist, and is there an OID to detect management

[Satyajit Behera]

I’m working with ServiceNow Discovery for network devices using SNMP. In some subnets, the same device responds on multiple IPs (loopback, SVI VLANs, management interface, etc.). I want to understand:

1. Which IP does Discovery pick as the primary IP (cmdb_ci.ip_address) when multiple IPs are discovered?

2. Is there a way to modify the Discovery Pattern to identify and set the Management IP instead?

3. Is there a standard SNMP OID that returns the management IP?
