Hi all,
We have a Dell "N1548 " switch, and we are attempting to TFTP from it, to our PC's. So far we are having issues. We can see that the TFTP Server recognises the server.
Within the main firewall, we have basically created an "any any" access list, to allow all communication from this switch to our desktops. There are NO ACLs configured on the switch. WIndows firewall is turned off, however we receive this message:
"
#copy running-config tftp://myipaddress/x.txt
Transfer Mode.................................. TFTP
Server IP Address..............................myipaddress
Destination File Path.......................... ./
Destination Filename........................... x.txt
Data Type...................................... Config Script
Source Filename................................ running-config
Management access will be blocked for the duration of the transfer
Are you sure you want to start? (y/n) y
TFTP Configuration Script transfer starting...
0 bytes transferred...
File transfer failed!
"
I can PING to this address, and we can traceroute as well. See:
"
#ping myipaddress
Pinging myipaddress with 0 bytes of data:
Reply From myipaddress: icmp_seq = 0. time= 69221 usec.
Reply From myipaddress: icmp_seq = 1. time= 18150 usec.

----myipaddress PING statistics----

"
#traceroute myipaddress
Traceroute to myipaddress ,30 hops max 0 byte packets:
1 mydefaultgateway <1 ms <1 ms <1 ms
2 myipaddress <1 ms * <1 ms
Hop Count = 2 Last TTL = 2 Test attempt = 6 Test Success = 5"
This is the same for directly connected networks too. We can't see there being any issues regarding say the firewall, as we allowed any traffic through, and still we get this error. The file does "transfer" as such, but it transfers with 0 bytes of data. See the below response that we get from the SolarWinds TFTP Server as well. This works much the same, whether you name the file as "x.backup" or "x.bak" or "x.txt"
Any help would be appreciated,
Thanks
