Add Credentials

OpManager Nexus accesses the remote devices using the protocols SNMP, CLI, or WMI. The credentials like the password/SNMP community, port etc., may differ for different device types. Pre-configuring a set of credentials in OpManager Nexus helps applying them to multiple devices at a time, saving a lot of manual effort.

1. Go to Settings > Discovery > Credentials
2. Click Add Credential
3. Configure the following parameters and click Save to add the credentials:

Credential Category: Select the relevant category.

• Monitor: Select this if the credential is to monitor a device.
• Backup: Select this if the credential is to take backup of device configuration.

Credential Type: Select the relevant protocol.

• SNMP v1/SNMP v2: SNMPv1 and SNMPv2 are community based security models. Enter the Credential name and description. Configure the correct Read and Write community, SNMP Port, SNMP Timeout (in seconds) and SNMP Retries.
• SNMP v3: SNMPv3 is a user based security model. It provides secure access to the devices by a combination of authenticating and encrypting packets over the network. The security features provided in SNMPv3 are Message integrity, Authentication and Encryption. Configure the following parameters:
  1. Name: Enter the name of the credential.
  2. Description: Enter a brief description about the credential.
  3. User Name: Enter the name of the user (principal) on behalf of whom the message is being exchanged.
  4. Context Name: A collection of management information accessible by an SNMP entity. The "context name" is an octet string which has at least one management information.
  5. Authentication: Select either MD5 or SHA and enter the password.
  6. Encryption: Select either DES or AES-128 and enter the password. Note: Authentication must be configured before Encryption.
  7. SNMP Port: Enter the SNMP port number.
  8. SNMP Timeout: Enter the SNMP timeout in seconds.
  9. SNMP Retries: Enter the number of SNMP retries.
• WMI (DCOM/WinRM): Configure the Domain Name, User Name, and Password (e.g. TestDomain\TestUser). Also enter the credential name and description. WinRM is also supported as a transport option for WMI-based monitoring; for setup steps, see WinRM for Windows Monitoring.
• Telnet/SSH: Enter the credential name. Select protocol Telnet or SSH. For Telnet, configure the correct login prompt, command prompt, password prompt, user name, password, port number, and timeout. For SSH, if using SSH Key Authentication, configure the user name, SSH Key (via Browse button), command prompt, port number, and timeout.
• VMware: Enter the credential name. Provide the HTTPS Username and Password of the Host. Enter the HTTPS web service port number and timeout interval for the connection between the Host and OpManager Nexus server.
• Citrix: Enter the credential name. Provide the Username and Password of the Host. Enter the web service port number and timeout interval for the connection between the Host and OpManager server.
• UCS: Enter the credential name. Provide the UCS Manager Username and Password. Enter the Port, Protocol, and Timeout interval for the connection between the UCS and OpManager Server.
