First step is to add the credentials of your device to BNA.
That can be done by adding a Device Security Profile. Login to BNA --> Admin --> Device Security Profile.
Second add the device details on Network --> Devices --> Add .
While adding a device , you can have “Access Mode” set to port 22 (SSH) or Port 23 (Telnet) and Transfer Mode set to tunnelled.
and what about FTP/SCP?
isn't there any need of SNMP credentials ?
For now , you can set Transfer Mode “Tunneled” for devices that support it.
Setting up FTP, SCP & TFTP is the next action.
