Yes, I understand what it would do. I still don't see why that's a helpful operation. It clearly provides a special failure mode. What isn't clear is why users of this feature would prefer to have the operation fail rather than having the system provide a best attempt (perhaps with warnings) instead. What are the administrators actually doing with these MAC addresses that causes them to prefer failure? -- James Carlson, Solaris Networking <james.d.carlson at sun.com> Sun Microsystems / 1 Network Drive 71.232W Vox +1 781 442 2084 MS UBUR02-212 / Burlington MA 01803-2757 42.496N Fax +1 781 442 1677
