Hi, I have setup a pair of 4431s (IOS XE 16.12.06) on a network but can't get any
copy run tftp
to work on either 4431. I have tested the tftp server using another cisco router on the same subnet and I don't have any issue. I can ping from the 4431s to the tftp server without issue. I also ran tcpdump on the tftp server while trying to do a
but I didn't see any connection attempts. Is there anything special to enable TFTP from a 4431 or anything else I can do to troubleshoot? Thanks!
Here's a command that I can run to get a failed transfer:
mp-gw3-ncss#copy run tftp://[ip address]/[filename].cfg
Address or name of remote host [ip address]?
Destination filename [filename.cfg]?
%Error opening tftp://[ip address]/[filename].cfg (Timed out)
mp-gw3-ncss#sho tech | redir
mp-gw3-ncss#sho tech | redirect tftp://[ip address]/[filename].txt
%Error opening tftp://[ip address]/[filename].txt (Timed out)

Yes you updated. But so much of the detail is redacted that it is difficult to know what parts might be significant. If this is tftp within your network then the addresses are probably Private addresses. So what is the reason to redact them.
After you attempt the tftp are there any entries in syslog that relate to this activity?
If you can ping from the router to the server that demonstrates basic IP connectivity. Which is good. Is it possible that on this router (or somewhere along the path to the server) is a security policy that is preventing tftp?
