Syntax:

SNMP_GETNEXT( $Alias, $MIBOID, $NextMIBOID) ==> $Value

Description:

Retrieves the value and the Object ID of the next logical MIB object to

a specified MIB object.

Action:

Additionally, the MIB object id of the next object is returned in the

$MIBOID. String expression. The MIB object id for which to get the
value. Refer to MIB OID on page 31 for more information.

MIB object from the specified MIB object (specified by the MIBOID

parameter).
