my interface is in a specific VRF
ip vrf forwarding MGMTxxx
ip address xxxxxxxxxx
and the global comand
ip tftp source-interface Loopbackx is also enable
the problem is
though I can ping to the ftp server
and I can telnet to the ftp server using port 21
I am not able to copy run tftp/....../sublocation/
any help is apreciated
Solved! Go to Solution.
you are copying file via FTP, but configured source-interface for TFTP.
If the guess is wrong, could you please share your configuration and failed attempt output?
PS: FTP is using TCP 21/20, TFTP is using UDP 69. Btw, you might need to configure FTP as passive (ip ftp passive) to use TCP 21 only, because TCP20 could be blocked somewhere.
On the source router is tftp or FTP enabled?
Tftp server xxxxx
Ip ftp username xxxx
ip ftp password xxx
ip ftp passive
ip ftp source-interface xxx

If you're having this problem on a device that doesn't support the vrf option at the end of the copy command, try just sourcing the ftp traffic from the interface that's in the vrf.
For example, on a 3850, the Managment port, Gi0/0, is in the Mgmt-vrf by default and can't be changed. Since I didn't have an option to use the vrf at the end of the copy command like you can on a 4500, I just did an 'ip ftp source-interface Gi0/0' and the copy command knew to use that Mgmt-vrf vrf to access the ftp server.
