Difference Between Credential and Credential-less discovery.

[Nand kishor Sha]

I have few question related to the credential less discovery:

1. What are the field's difference between Credential and Credential-less discovery?

2. Can we discover the SNMP device like IP Router and Stack Switches through credential less discovery?

Regards,

1) Credential discovery uses saved credentials and attempts to log into the device with them. Credential-less uses NMAP installed on the host machine to discover things about it.

2) SNMP devices use a community string which I believe is required.

Please mark this as helpful/correct if it resolved your issue!

Credential Discovery

Uses credentials from 'discovery_credentials' table based on the credential type to do a deep discovery of the given IP range. This will be enabled automatically when the credential is created and tested.

Credential-less Discovery

You have to explicitly enable this discovery on the MID server and install 'NMAP' on the mid server. This type of discovery runs Nmap commands to retrieve the limited information from the given ip range without using credentials.

2. Can we discover the SNMP device like IP Router and Stack Switches through credential less discovery?

It should be possible. 

Please mark this answer correct/helpful if it helps you

Hi, what are the devices which can get discovered only with credential-less discovery?

Thanks for the response!

Could you please provide the information in terms of fields for any one class? Suppose, we are doing the Network Appliance Hardware discovery from credential and Credential less discovery then what will be the field's difference during updating the CI?
