Symptom
DCNM LAN discovery is causing the following message to appear in the Nexus logs:
%DAEMON-3-SYSTEM_MSG: error: kex_exchange_identification: Connection closed by remote host - dcos_sshd[28871]
Conditions
This can be seen with DCNM 11.5 and NDFC 12.0
Workaround
These messages are harmless and can be ignored.
The messages will not appear if the logging level for "deamon" is set to a value below 3:
logging level daemon 2
There is a patch to fix this issue on top of DCNM11.5(4).
