          Hello,

          Normally we connect throu VPN to customer network, i was put the VPN ip address to the TFTP Server address.

          For example. My company network : 10.0.0.1 if i connect to VPN to customer network  i got 192.168.0.1 so i used to give the TFTP Server address 192.168.0.1. its failed to retrive the config files from customer network, at the same time i can able to ping and telnet to those devices, Please do the needful help

           

          Regards,

              Hari - a couple of things jump out at me here...

              Can you CLI TFTP a config file from the target device on the private network back through the VPN?

              Is UDP port 69 open on the TFTP server machine?

              Does the machine your are trying to get a config off have a route to the VPN network?

                  Hello,

                   

                  Thanks for your email.

                  1. TFTP services has started

                  2. Solar winds TFTP has started UDP 69.

                  3. I was tried to port scan tool, it shows port 69 closed.

                  4. TFTP has installed my company network. When i was trying to connect Customer Network to use VPN. once connected VPN i got one ip address.

                  5. I set the TFTP server ip address(connected VPN ip address).

                  6. After pass the snmp test, i can see the switch name, after that it will ask running config / startup config. i choose the below one, after that it shows the error msg.  "transfer failed no configuration information  avaliable on router".

                      Hari - The only time we should be reporting that error is if the device responded with a code 5 in the following MIB:

                      CISCO-CONFIG-COPY-MIB:ccCopyFailCause

                      OID     1.3.6.1.4.1.9.9.96.1.1.1.1.13
                      Type     ConfigCopyFailCause

                      http://tools.cisco.com/Support/SNMP/do/BrowseOID.do?local=en&translate=Translate&typeName=ConfigCopyFailCause

                      Which essentially means the device really has no config to transfer, or some permission is blocking it.

                      You can capture the SNMP traffic between the two to validate, or send me a copy and I will check it out for you.

                      HTH,

                              Hari - Using a sniffer like Wireshark, capture the UDP port 161 traffic on the VPN interface (while attempting to download a config) and send it to me.

                                      Hari - can you please get me a capture file in the binary pcap format (so I can open it in Wireshark)? The text version you sent in does not have all of the SNMP fields included (specifically the values of the VarBinds).

                                              Hi Hari - I see two transfer attempts in your capture.  The device is definitely telling us that it has no config to transfer (packet analysis down below), but I think it might be confused...

                                              What happens and what do you see on the debug console when you CLI the following commands:

                                              1. debug tftp events
                                              2. debug tftp packets
                                              3. copy run tftp: (follow the prompts using the address of the vpn adapter as the destination)

                                              If you get a fail to connect, you need to debug that.  If you can connect and it transfers fine, then you will need to open a Cisco TAC case (if you think the device should actually have a config to transfer).

                                               

                                              *Packet Analysis*

                                              If you look at packet 163, you can see where we are asking the device the status of the transfer, and it replies with a 4 (in packet 164), which if you look up the code here, you will see the following values:

                                                                                                                                                                        1 : waiting
                                                                                                                   2 : running
                                                                                                                   3 : successful
                                                                                                                   4 : failed

                                              Then in packet 165 we ask for the reason for the failure, to which the device responds with a "5" (in packet 166). You can look up the mean of the 5 here.

                                              CISCO-CONFIG-COPY-MIB:ccCopyFailCause

                                              OID     1.3.6.1.4.1.9.9.96.1.1.1.1.13
                                              Type     ConfigCopyFailCause

                                               

                                              You will see the following values:

                                              1 : unknown
                                                                                                                   2 : badFileName
                                                                                                                   3 : timeout
                                                                                                                   4 : noMem
                                                                                                                   5 : noConfig

                                              So, the device is telling us that there is no config to download.  If you believe it should have a config that can be downloaded, again, the only thing I can recommend is to open a TAC case with Cisco.
