Explanation
These messages indicate that ExtremeWare supports a previous version of 3DNS (v2.0). The newer
versions of 3DNS send an iQuery hello message that the switch does not recognize. The switch then
sends an
unrecognized message back to 3DNS. This message causes 3DNS to fall back to an older
version of the iQuery protocol. The process repeats until both 3DNS and the switch agree on the iQuery
protocol version.
If the error message is logged multiple times, it might be due to 3DNS using encryption.
NOTE
The Extreme implementation does not support encryption, so encryption must be disabled on 3DNS.
Action
If the switch and the server are only trying to negotiate a correct version of 3DNS support, then no
action is necessary.
If the messages occur multiple times, disable the encryption on the 3DNS box.
