• SNMP Get Community Name

The user sets the global credentials. HP Web Jetadmin then uses the global credentials when a

credential is needed, but the credential is not available in the Credentials Store. Multiple values can

be set for global credentials. HP Web Jetadmin tries each credential value in the stack until it

encounters success. If the application uses a global credentials value and it results in a success, that

value is stored for that device in the Credentials Store. If success is not achieved, the device is placed

in a credentials needed state.

In Tools > Options > Credentials, the following options are available to clear the stored credentials:

• Clear All Credentials—Removes all the device credentials from the Credentials Store in the

HP Web Jetadmin database.

• Clear Global Credentials—Clears all the global values stored in each of the credential types.

Credentials needed

When HP Web Jetadmin performs an action, such as a device configuration, and encounters a

device with a credential, such as an SNMP Set Community Name, it follows a specific sequence. The

following is a simplified example of how HP Web Jetadmin attempts to resolve a credential:

1. Checks the store for the credential.

• If the credential exists, attempts the configuration using the credential value.

• If the credential does not exist, goes to the global credentials.

• If the credential succeeds, stops.

• If the credential fails, goes to the global credentials.

2. Checks for a global credential.

• If a global credential exists, attempts the configuration using the global credential value.

• Else, logs a credential-needed,

and prompts the user if it is a

live configuration session.

• If the credential succeeds, stops,

and adds the credential to the

device store.

• Else, logs a credential-needed,

and prompt the user if it is a live

configuration session.

During a live user-attended configuration

session, HP Web Jetadmin prompts for

credentials (Figure 11).

If the user did not supply the credential or the session was not live, the device is flagged as requiring

credentials. This state can be observed in the Credentials Required column that can be enabled in any

device list (Figure 12). To resolve this state, users can right-click the device, and add the needed

credential to the system.
