dsx0BundleNextIndex OBJECT-TYPE

    SYNTAX  TestAndIncr

    MAX-ACCESS  read-write

    STATUS  current

    DESCRIPTION

            "This object is used to assist the manager in

            selecting a value for dsx0BundleIndex.  Because

            this object is of syntax TestAndIncr (see the

            SNMPv2-TC document, RFC 1903) it can also be used

            to avoid race conditions with multiple managers

            trying to create rows in the table.

            If the result of the SET for dsx0BundleNextIndex

            is not success, this means the value has been

            changed from index (i.e. another manager used the

            value), so a new value is required.

            The algorithm is:

            done = false

            while done == false

                index = GET (dsx0BundleNextIndex.0)

                SET (dsx0BundleNextIndex.0=index)

                if (set failed)

                  done = false

                else

                  SET(dsx0BundleRowStatus.index=createAndGo)

            also provides synchronization during

            n x 56/64 kbit/s data channels for most values of

            n). Mode 3 provides all of the above, but also

            provides n x 56/64 kbit/s data channels.  Most

            common implementations of Mode 3 add an extra

            channel to support the inband monitoring overhead.
