Question:

Why am I having difficulty downloading a config file from a Cisco router?

Resolution:

Use the following checklist to help troubleshoot your config downloads:

Use the most up-to-date version of the SolarWinds Cisco Config Viewer.

Many Cisco devices stopped supporting the Config Transfer MIB used by the old SolarWinds 2000 toolset. The SolarWinds 2001 Toolset and later versions determine the supported MIBs before requesting a config from the router. Additionally, the old SolarWinds 2000 Toolset does not support transfering config files to and from Cisco Catalyst devices. Config transfers to and from Catalyst devices are only supported in the SolarWinds 2001 Toolset and later versions.

Allow TFTP file transfers through your firewall.

Your firewall must allow incoming TFTP requests on UDP port 69.

Ensure that the TFTP Server is running.

The Config Download should start the TFTP Server automatically. If it does not, start the TFTP server manually.

  1. Run the TFTP Server.
  2. From the File menu, click Configure.
  3. Click Start.

Configure the TFTP Server for receiving

Clear any TFTP server settings that may be blocking incoming connections.

  1. Run the TFTP Server.
  2. From the File menu, click Configure.
  3. Click the Security tab.
  4. Click Receive files.
  5. Click Allow all IP addresses to send/receive files.

Set the Config Viewer TFTP Server address to your PC.

If your PC is on dial-up, or has multiple interfaces and IP addresses, you may need to manually set the IP address of the TFTP server to the IP address of your PC.

  1. Run the Config Viewer
  2. From the File menu, click Preferences.
  3. Click the TFTP Server Address tab.
  4. Click Manual - specify IP address of the TFTP Server.
  5. In the IP address of TFTP Server box, enter the IP address of your PC.

Look for access list entries on the Cisco router that may be blocking SNMP requests or TFTP file transfers.

Look for a line in the Cisco config similar to this:

snmp-server community public RO 60

The "60" at the end of this line refers to an access list. You can add your computer's IP address to this access list or remove the access list entirely.
