Add Credentials

 

OpManager 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 helps applying them to multiple devices at a time, saving a lot of manual effort.

 

1.Go to Admin --> Credential Settings

2.Click New in this screen

3.Configure the following parameters and click Add 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 the 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. 

  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: 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.
  5. SNMP Port: Enter the SNMP port number.
  6. 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.
  7. 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.

WMI: If you select WMI as the protocol, configure the Domain Name, the user name, and the password. Example:- TestDomain\TestUser. Also enter the credential name and description.

Telnet/SSH: Enter the credential name and description. For Telnet/SSH, make sure you configure the correct login prompt, command prompt, and password prompt besides the user name and password to access the device.

VMware: 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 server.  

The SNMP credentials created is used during the initial discovery and classifications. OpManager uses these credentials to classify and add the devices into OpManager.

 

Using Quick Configuration Wizard


You can also use the Quick Configuration Wizard to associate a service to several devices at one go. Here are the steps:

  1. From the Admin tab, select Quick Configuration Wizard.
  2. Select the option Associate a credential to several devices and click Next.
  3. All the available Credentials are listed. Select the Credential which you want to associate to your devices.
  4. Select the devices to which you want to assign the credential from the column on the left and move them to the right.
  5. Click Finish. The Credential is associated to the selected devices.
