After the upgrade 11.1 to 12.0.2
In random time my log are not showing anymore the disconnect message example "A fibre channel port changed its operational state;Port 5 (0/5) changed operational state to offline"
I need to restart the service network advisor to receive again the message "A fibre channel port changed its operational state;Port 5 (0/5) changed operational state to online"
Anyone have the same problem?

when an online port goes offline a few traps are sent to the BNA reporting the change os status. If these traps stop being showed by BNA could have a few reasons:
- That the BNA is no longer registered to receive snmp traps. When you experience this, please, check the output of snmpconfig --show <snmp_version> in order to see if the server is correctly configured to receive traps.
- That traps are not reaching the BNA server. I personally like wireshark to check if traps are reaching the server.
- That the BNA receives the traps with success but does not process them. I suppose that in your case, this is the most likely scenario. when I have experienced this, I managed to fix it by re-discovering the affected switch modifying some snmp parameter (such as, community, snmp version, etc.).
When you restart the BNA services, the switchs are rediscovered, snmp is re-registered and all the possible causes of the failure are restarted.
