Notes on TFTP Service for ACM Operation

A NIOS appliance can also operate as a TFTP server. The enterprise network may also have an existing public TFTP server. For more information on us ing a NIOS appliance as a TFTP server, see the Infoblox NIOS Administrator Guide, Chapter 8, File Distribution Services.

For initial bring-up of the bare-metal device, NetMRI's TFTP server directory contains a small Cisco or Juniper configuration file. The two files are called:

• network_confg (Cisco)
• router.conf (Juniper)

Other files may also be present. You can also create your own.

Each file contains the organization's assigned device IP address and assigned credentials for the Enable and Telnet/SSH passwords and secret settings. A sample network_confg file includes the basic credentials for the Enable password and for telnet and SSH access, and enables SNMP:

username autoconfig privilege 15 password 0 autoconfig

snmp-server community autoconfig RO

line vty 0 4

exec-timeout 60 0

logging synchronous

login local

transport input telnet ssh

end

A sample Juniper file is in the topic Sample Juniper router.conf File.

If the administrator wants to deviate from the autoconfig string (i.e. for hostname, community string and/or CLI credentials), the following holds true:

• The defined hostname must remain autoconfig;
• You can change the community string, and you should update the global community string guesser list with the desired community string;
• You can change CLI credentials, and you should update the global CLI credentials guesser list with the desired CLI credentials (i.e. username, password and enable password);
• The stub configuration files must be updated to reflect desired changes, and if using NetMRI's TFTP server, redeployed using the admin shell tftpsync command.

You can edit the configuration files to contain your own credentials and settings. Access configuration files by using the NetMRI administrative shell and entering an ls tftp command. When finished, run the NetMRI tftpsync command to move these files into the public TFTP server file system.
