SNMP_GET

Syntax:

SNMP_GET( $Alias, $MIBOID) ==> $Value

Description:

Retrieves the value of a specified MIB object.

Action:

The value of the object specified by the MIBOID parameter in the MIB

of the Alias is returned as a string.

Parameters:

$Alias. String expression. The NMS alias from which to get the MIB

object value. The specified alias must not be a group alias. Refer to

NMS Alias on page 31 for more information.

$MIBOID. String expression. The MIB Object ID to get the value for.

Refer to MIB OID on page 31 for more information.

Returns:

String value, as follows:

Value Meaning

“” (null string) The MIB object does not exist.

Any other value The value of the MIB object.

Notes:

1. Append “.0” to the MIB Name. Alternatively, use the

SNMP_GET() command to enter a branch of the MIB, and the

SNMP_GETNEXT() command to retrieve specific values from that

branch.

2. For error checking of SNMP_GET(), refer to the description of the

ERRORNUM() command.

Example:

//This sample code enters the sysName branch and grabs

// the value of sysName.

//Note that the alias must be defined in SNMP Setup.

$Alias := “RS6000”

$MIBOID := “sysName”

$RetVal := SNMP_GET( $Alias, $MIBOID)

$SystemName := SNMP_GETNEXT( $Alias, $MIBOID,

$NextMIBOID)

//$SystemName now contains the value of sysName.

//Example2

//This gets the value of sysName by appending a “.0”

// to the end of the branch name.

$Alias := “RS6000”

$MIBOID := “sysName”

$MIBOIDValue := $MIBOID + “.0”

$SystemName := SNMP_GET( $Alias, $MIBOIDValue)

//$SystemName now contains the value of sysName.
