If this object is set to the IPX address of a node to link test in the same PDU that sets linkTestRepetitions to a nonzero value, the link test performed will use IPX diagnostic packets. Note that setting more than one of linkTest802MacAddress, linkTestIpAddress, and linkTestIpxAddress to a non-null value in the same PDU will result in a genErr.
