How to configure discovery credentials for the latest Network Configuration Manager version?
Pre-configuring a set of credentials in Network Configuration Manager helps applying them to multiple devices at the same time and saves a lot of manual effort. Although you can also access the add credential option while doing the a new discovery by clicking the Add Icon next to Credential option. To pre-configure credential profile please follow the instruction given below:
- Go to Settings > Discovery > Credentials
- Click Add Credential in this screen
- Configure the following parameters and click Save to add the credentials:
Credential Type: Select the relevant protocol.
SNMP v1/SNMPv2: SNMPv1 and SNMPv2 are community based security models. Enter the Credential name and description. Configure the correct Read and Write Community and SNMP Port.
SNMP v3: SNMPv3 is a user based security model. It provides secure access to the devices by a combination authenticating and encrypting packets over the network. The security features provided in SNMPv3 are message integrity, authentication and encryption. If you select SNMPv3 as the credential type, then configure the following parameters:
Name: Enter the name of the credential.
Description: Enter a brief description about the credential.
User Name: Enter the name of the user (principal) on behalf of whom the message is being exchanged.
Context Name: An SNMP context name or "context" in short, is a collection of management information accessible by an SNMP entity. An item of management information may exist in more than one context. An SNMP entity potentially has access to many contexts. In other words, if a management information has been defined under certain context by an SNMPv3 entity, then any management application can access that information by giving that context name. The "context name" is an octet string, which has at least one management information.
SNMP Port: Enter SNMP port number.
Authentication: Select any of the authentication protocols either MD5 or SHA and enter the password. MD5 and SHA are processes which are used for generating authentication/privacy keys in SNMPv3 applications.
Encryption: Select any of the encryption protocols either DES or AES-128 and enter the password.
Note: Only after configuring Authentication it is possible to configure Encryption.
