This object contains an unused value for next L2PT translate instance on a module that can be used to implement L2PT translation, or a zero to indicate that none exist. This value needs to be read in order to find an available index for row-creation of a L2PT translationinstance and then used when a row is created. This value is automatically updated by the SNMP Agent after the row is created.
