Additional Access Points | In addition to accessing this MBean by invoking a factory method, you can also access this MBean from the following MBean attributes:
SNMPAgentMBean.TargetedTrapDestinations |

## Attributes

This section describes the following attributes:

Community Host Name Notes | Parent Port Type

### Community

The password (community name) that WebLogic Server sends to the SNMP manager.

Note that there are two community names that are needed when WebLogic Server interacts with an SNMP manager:

- The community name that the SNMP manager defines. The community name that you enter in this trap destination must match the name that the SNMP manager defines. The WebLogic SNMP agent sends this name when connecting to the manager.

- The name that you specify in the WebLogic SNMP agent's Community Prefix. All SNMP managers must send this name when connecting to the WebLogic SNMP agent.

Privileges | Read/Write
Type | java.lang.String
Default Value | public

### Host

The DNS name or IP address of the computer on which the SNMP manager is running.

The WebLogic SNMP agent sends trap notifications to the host and port that you specify on this tab.

Privileges | Read/Write
Type | java.lang.String
Default Value | localhost
Secure value | 127.0.0.1

### Name

The user-specified name of this MBean instance.

This name is included as one of the key properties in the MBean's `javax.management.ObjectName`:
`Name=user-specified-name`

Privileges | Read/Write
Type | java.lang.String

### Notes

Optional information that you can include to describe this configuration.

WebLogic Sever saves this note in the domain's configuration file (`config.xml`) as XML PCDATA. All left angle brackets (<) are converted to the XML entity `&lt;`. Carriage returns/line feeds are preserved.

Note:

  If you create or edit a note from the Administration Console, the Administration Console does not preserve carriage returns/line feeds.

Privileges | Read/Write
Type | java.lang.String

### Parent

Return the immediate parent for this MBean

Privileges | Read/Write

### Port

The port on which the SNMP manager is listening.

Privileges | Read/Write
Type | int
Default Value | 162
Minimum value | 1
Maximum value | 65535

### Type

Returns the type of the MBean.

Privileges | Read only
Type | java.lang.String
Redeploy or Restart required | Changes take effect after you redeploy the module or restart the server.

## Operations

This section describes the following operations:

freezeCurrentValue isSet restoreDefaultValue | unSet

### freezeCurrentValue

If the specified attribute has not been set explicitly, and if the attribute has a default value, this operation forces the MBean to persist the default value.

Unless you use this operation, the default value is not saved and is subject to change if you update to a newer release of WebLogic Server. Invoking this operation isolates this MBean from the effects of such changes.

Note:

  To insure that you are freezing the default value, invoke the `restoreDefaultValue` operation before you invoke this.

This operation has no effect if you invoke it on an attribute that does not provide a default value or on an attribute for which some other value has been set.

Deprecated. 9.0.0.0

Operation Name | `"freezeCurrentValue"`
Parameters | `Object [] { attributeName }` where: `attributeName` is an object of type `java.lang.String` that specifies: attributeName
Signature | `String [] { "java.lang.String" }`
Returns | `void`
Exceptions | `javax.management.AttributeNotFoundException` `javax.management.MBeanException`

### isSet

Returns true if the specified attribute has been set explicitly in this MBean instance.

Operation Name | `"isSet"`
Parameters | `Object [] { propertyName }` where: `propertyName` is an object of type `java.lang.String` that specifies: property to check
Signature | `String [] { "java.lang.String" }`
Returns | `boolean`

### restoreDefaultValue

If the specified attribute has a default value, this operation removes any value that has been set explicitly and causes the attribute to use the default value.

Default values are subject to change if you update to a newer release of WebLogic Server. To prevent the value from changing if you update to a newer release, invoke the `freezeCurrentValue` operation.

This operation has no effect if you invoke it on an attribute that does not provide a default value or on an attribute that is already using the default.

Deprecated. 9.0.0.0

Operation Name | `"restoreDefaultValue"`
Parameters | `Object [] { attributeName }` where: `attributeName` is an object of type `java.lang.String` that specifies: attributeName
Signature | `String [] { "java.lang.String" }`
Returns | `void`
Exceptions | `javax.management.AttributeNotFoundException`

### unSet

Restore the given property to its default value.

Operation Name | `"unSet"`
Parameters | `Object [] { propertyName }` where: `propertyName` is an object of type `java.lang.String` that specifies: property to restore
Signature | `String [] { "java.lang.String" }`
Returns | `void`
