Installed (TCP/IP)

  • Artykuł

The TCP/IP Installed construct contains the object ID (OID) of the MIB table's row and a list of lookup values. If any of the lookup values exists in the row, this algorithm returns TRUE. Most queries related to configuration of the printer should determine whether there is a particular value stored in the printer's MIB and then return a Boolean result. The Installed construct is defined in Tcpbidi.xsd.

Attribute Description
deviceIndex (Optional) A flag that, when TRUE, means that the associated algorithm must include the device index in the specified OID; when FALSE, a trailing zero is appended to the OID. The default value is FALSE. For more information, see the note on the page for Value.
drvPrinterEvent (Optional) A Boolean value that indicates whether the port monitor sends notifications to the driver. A TRUE value indicates that the port monitor sends notifications to the driver; FALSE indicates that the port monitor does not send notifications to the driver.
name The name of the schema value.
oid The row of the MIB table, as an OID.
refreshInterval The value of the polling interval, in seconds. The default value is 600 seconds.

Code Example

In the following code example, the lookup algorithm retrieves the MIB table row from 1.3.6.1.2.1.43.13.4.1.9.<deviceIndex>. If this table row contains either 3 or 4, the query returns TRUE; otherwise the query returns FALSE.

<Property name="DuplexUnit">
  <Installed name="Installed" oid="1.3.6.1.2.1.43.13.4.1.9" deviceIndex="true">
    <Lookup value="3"/>
    <Lookup value="4"/>
  </Installed>
</Property>

The preceding example results in the following query:

\Printer.Configuration.DuplexUnit:Installed
