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
Credential Type: Select
the relevant protocol.
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.
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
- Name: Enter the name of
- 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
- 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 the SNMP
- 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 EAS-128 and enter the password.
Note: Only after configuring Authentication it is possible to configure
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.
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
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:
- From the Admin tab, select Quick Configuration Wizard.
- Select the option Associate a credential to several
devices and click Next.
- All the available Credentials are listed. Select the Credential
which you want to associate to your devices.
- Select the devices to which you want to assign the credential
from the column on the left and move them to the right.
- Click Finish. The Credential is associated to the selected
