SNMP actor adapter requests and responses with a notification action

The format of the SNMP actor adapter request with a notification action depends on the SNMP version.

When you use a context item as an input for an adapter request, you must enclose the adapter request in the <request-data> elements. However, when you create a static request, <request-data> is not required and the adapter request starts with the <adapterName-adapter-request> element.

BMC recommends that you do not include empty elements in the adapter request because they might cause errors.

The following table describes the common elements for the SNMP actor adapter request with a notification action for SNMPv1, SNMPv2c, and SNMPv3 traps.

Common elements for SNMP actor adapter request with a notification action for SNMPv1, SNMPv2c, and SNMPv3 traps

Element

Description

Required

<target-host>

Specifies the host name or the IP address of the target computer that receives the SNMP notification

Yes

<source-host>

Specifies the host name or the IP address of the source computer that sends the SNMP notification

If you do not provide this value, the host information for the peer on which the adapter request is being executed is used.

No

<port>

Specifies the target port for the SNMP notification

Default value: 162

No

<version>

Specifies the SNMP version to be used

Valid values: 1 (default), 2c, 3

No

<oids>

Contains the <oid> nodes used to specify dynamic values

Yes; even if <oid> nodes are not defined

<oid>

Contains the name and value pair for the OID (object identifier) notification

Conditional; required if the <name>, <value>, and <type> elements are defined

<name>

Specifies the OID reference name used in the adapter response

Example: .1.1.4.6.1.2.6.2.5

Note

The <name>, <value>, and <type> element group is ignored ifyou do not specify all of the elements in the group and a value for each.

No

<value>

Specifies the OID for which information is returned

The value of this element depends on the value of the <type> element. For example, if the value of the <type> element is "integer", <value> can be any valid integer.

Note

The <name>,<value>, and <type> element group is ignored if you do not specify all of the elements in the group and a value for each.

No

<type>

Specifies the OID data type

Valid values:

  • STRING (default) (Valid value: Any string)
  • INTEGER (Valid value: Any integer)
  • OBJID (Valid value: The value for the <value> element, for example, .1.1.4.6.1.2.6.2.5)
  • IPADDRESS (Valid value: A valid IP address, for example, 10.1.10.111)
  • NETWORKADDRESS (Valid value: Any valid IP address, for example, 10.1.10.111)
  • COUNTER (Valid value: Any integer)
  • GAUGE (Valid value: Any integer)
  • UNSIGNED32 (Valid value: Any integer)
  • TIMETICKS (Valid value: Any integer)
  • COUNTER64 (Valid value: Any integer) (The COUNTER64 value works only for SNMP version 2c and version 3)
  • NULLOBJ (If <type> is set to "NULLOBJ", the <value> element is not required and is ignored if provided)
  • OPAQUE (Valid value: Any integer)

    Notes

    • The <name>,<value>, and <type> element group is ignored if you do not specify all of the elements in the group and a value for each.
    • If you provide an incorrect value for <type>, the adapter resets the value to STRING, the default value.

No

<character-set>

Specifies the supporting CharSet

Also called character set, it includes identifiers describing a series of universal characters.

Default value: ISO-8859-1

No
