Types of Credentials used in OpManager

Monitoring Credentials (SNMP v1/v2, SNMPv3, Telnet, SSH, WMI, VMWare, Citrix, UCS, Nutanix):

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.

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: SNMP v3 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 SNMP v3 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.
  • 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 SNMP v3 applications.
  • Encryption: Select any of the encryption protocols either DES or EAS-128 and enter the password. Note: Only after configuring Authentication it is possible to configure Encryption.
  • SNMP Port: Enter the SNMP port number.
  • SNMP Timeout: Enter the SNMP timeout in seconds.
  • SNMP Retries: Enter the SNMP retries.

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. Select protocol Telnet or SSH. For Telnet, ensure you configure the correct login prompt, command prompt, and password prompt besides the user name, password, port number and timeout (in seconds) to access the device. For SSH, if you select SSH Key Authentication, ensure you configure the user name and choose the SSH Key using the Browse button, and correct command prompt besides the port number and timeout (in seconds) to access the device.

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 server.

Citrix: Enter the credential name. Provide theUsername 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.

Nutanix: Provide the username and password of the Prism API element, the protocol being used (HTTP/HTTPS), the timeout value for the connection and the port in which the Prism element is running.

Backup Credentials (Telnet, SSH, SNMP v1, SNMP v2c, SNMPv3):

This module helps in automating Router/Switch config backup/restore, Compliance check and Network configuration changes periodically. The backup credentials are used for discovering devices into Network Configuration Manager module. This module uses these credentials for taking Router/Switch config backup, and to perform compliance check and config change management periodically.

Storage Credentials (SNMP v1/v2, v3, CLI, SMI, NetAppAPI) :

The Storage credentials are used for discovering storage devices into Storage module. This module enables storage monitoring of Disk, LUN, RAID etc.The Storage credentials helps you to monitor the storage devices like Storage Arrays, Fabric Switches, Tape Libraries, Tape Drives, Host servers and Host Bus Adapters cards from all leading vendors in the industry.
