When Online Backup or an SS restart is performed it is noted on firewall logs and ACL logs that SSH packets are being sent to devices.
Noted here is why these packets are sent:
If NCM is not used in Spectrum, we can disable the NCMService which will stop these packets.
1. Navigate to $SPECROOT/lib/SDPM/partslist/
2. Open NCMSERV.idb in a text editor
4. Save the file.
5. Restart the Spectrum Process Daemon
NCMService will no longer start and thus these packets will not be sent.
Please note that NCM will no longer work once this is done.
Reverse the process if you would like NCM to be enabled again.
