EZZ9782I

Explanation
 A full, manually configured address was configured
for the specified interface. The link-local address generated by using
the hardware-provided interface ID failed the duplicate-address detection
process. A randomly generated interface ID was tried and also failed
the duplicate-address detection process. If this is the first randomly
generated interface ID, a second randomly generated interface ID will
be tried. No more than two randomly generated interface IDs will be
tried. 
 addr is the alternate address generated
using a random interface ID. 
 interface is
the interface name.

System action
 TCP/IP continues.

Operator response
 None.

System programmer response
 Message EZZ9780I indicates the original
link-local address that failed duplicate-address detection. Check
the OSA setup to determine why its interface ID is not unique. If
both attempts with alternate interface IDs failed, restarting the
interface again might generate a unique ID successfully. If subsequent
attempts fail with the same error, consider bypassing duplicate-address
detection (by specifying DUPADDRDET 0 on the INTERFACE statement)
until the source of the problem can be resolved.
