Troubleshooting configuration snapshot failures

Observe the following guidelines when using the File Transfer Protocol (FTP), Trivial FTP (TFTP), or Secure Copy (SCP) file transfer mode:

  • Ensure that all firewalls between the BMC Network Automation local and remote device agents and the managed devices are not blocking file transfer service application ports (TFTP, FTP, or SCP). Ensure any host-based firewall (such as a Windows firewall) is not blocking such traffic. BMC Network Automation initiates file transfer from the device for Snapshot and Deploy actions, so the device acts as the client side in the socket connection. To unblock ports in the Windows firewall on the BMC Network Automation server, see Unblocking ports.
  • Ensure that the appropriate file transfer service (TFTP, FTP, or SCP) is running on the local or remote device agent according to Verifying the installation. For Windows, BMC Network Automation automatically installs and starts a TFTP server, but the FTP and SCP services must be installed and started separately.
  • When using the FTP or SCP service, ensure that the following options under Admin > Network Admin > Device Agents for the Device Agent configured for the device are selected:
    • Enable FTP Transfer Mode
    • Enable SCP Transfer Mode
  • Manually attempt the configuration file transfer from the device. Refer to the BMC Network Automation job transcript to view the commands that BMC Network Automation executes. Following is an example of a Snapshot action using TFTP on a Cisco IOS router:
    1. Telnet to the device (router).
    2. Log on and go into enable mode.
    3. Type copy running-config tftp.
    1. When prompted for the address of the remote host, enter the BMC Network Automation device agent IP address.
    2. When prompted for the destination file name, type temp.tmp.
  • If the preceding test fails, the BMC Network Automation device agent might be behind a Network Address Translation (NAT) server. Find the IP address that the router uses to address the device agent. Edit the device record's NAT Address field by entering the device-facing address of the device agent.

Note

While using the Tunneled file transfer mode, you perform configuration snapshot by capturing the output of show type commands, for example, show running-configuration. You make configuration changes by batching CLI commands to the device.
