Defining and Configuring the Trap Target Parameters

Target parameters define the message processing and security parameters that are used in sending notifications to a particular management target.

To define a set of target parameters, include the target-parameters statement at the [edit snmp v3] hierarchy level:

[edit snmp v3]target-parameters target-parameters-name;

target-parameters-name is the name assigned to the target parameters.

To configure target parameter properties, include the following statements at the [edit snmp v3 target-parameters target-parameter-name] hierarchy level:

[edit snmp v3 target-parameters target-parameter-name]notify-filter profile-name;parameters {message-processing-model (v1 | v2c | V3);security-level (authentication | none | privacy);security-model (usm | v1 | v2c);security-name security-name;}

This topic includes the following sections:

Applying the Trap Notification Filter

To apply the trap notification filter, include the notify-filter statement at the [edit snmp v3 target-parameters target-parameter-name] hierarchy level:

[edit snmp v3 target-parameters target-parameter-name]notify-filter profile-name;

profile-name is the name of a configured notify filter. For information about configuring notify filters, see Configuring the Trap Notification Filter.

Configuring the Target Parameters

To configure target parameter properties, include the following statements at the [edit snmp v3 target-parameters target-parameter-name parameters] hierarchy level:

[edit snmp v3 target-parameters target-parameter-name parameters]message-processing-model (v1 | v2c | v3);security-level (authentication | none | privacy);security-model (usm | v1 | v2c);security-name security-name;

This section includes the following topics:

Configuring the Message Processing Model

The message processing model defines which version of SNMP to use when generating SNMP notifications. To configure the message processing model, include the message-processing-model statement at the [edit snmp v3 target-parameters target-parameter-name parameters] hierarchy level:

[edit snmp v3 target-parameters target-parameter-name parameters]message-processing-model (v1 | v2c | v3);
  • v1—SNMPv1 message processing model
  • v2c—SNMPv2c message processing model
  • v3—SNMPV3 message processing model

Configuring the Security Model

To define the security model to use when generating SNMP notifications, include the security-model statement at the [edit snmp v3 target-parameters target-parameter-name parameters] hierarchy level:

[edit snmp v3 target-parameters target-parameter-name parameters]security-model (usm | v1 | v2c);
  • usm—SNMPv3 security model
  • v1—SNMPv1 security model
  • v2c—SNMPv2c security model

Configuring the Security Level

The security-level statement specifies whether the trap is authenticated and encrypted before it is sent.

To configure the security level to use when generating SNMP notifications, include the security-level statement at the [edit snmp v3 target-parameters target-parameter-name parameters] hierarchy level:

[edit snmp v3 target-parameters target-parameter-name parameters]security-level (authentication | none | privacy);
  • authentication—Provides authentication but no encryption.
  • none—No security. Provides no authentication and no encryption.
  • privacy—Provides authentication and encryption.

    Note: If you are configuring the SNMPv1 or SNMPV2c security model, use none as your security level. If you are configuring the SNMPv3 (USM) security model, use the authentication or privacy security level.

Configuring the Security Name

To configure the security name to use when generating SNMP notifications, include the security-name statement at the [edit snmp v3 target-parameters target-parameter-name parameters] hierarchy level:

[edit snmp v3 target-parameters target-parameter-name parameters]security-name security-name;

If the USM security model is used, the security-name identifies the user that is used when the notification is generated. If the v1 or v2c security models are used, security-name identifies the SNMP community used when the notification is generated.

Note: The access privileges for the group associated with a security name must allow this notification to be sent.

If you are using the v1 or v2 security models, the security name at the [edit snmp v3 vacm security-to-group] hierarchy level must match the security name at the [edit snmp v3 snmp-community community-index] hierarchy level.
