OK, this is an odd one. I have a couple of VxWorks device on the same subnet as a windows server 2008 (that they require talking to). When we run an arpShow from any of the VxWorks devices, the server's MAC shows up missing the last digit in the table. Actually i believe it's the second to the last as it shows as xx:xx:xx:xx:xx:9 when it should be xx:xx:xx:xx:xx:09.
Any ideas? I don;'t have anything else on that subnet, and communication began to get iffy between the server and VxWorks devices recently after a subnet change.
