Good Evening - we are having a strange TFTP issue with a startup-config and a 7750 and i am hoping it is something silly that some might recognize!
We are connected locally to the switch console port - no issues.
We also have a local connection with the switch management port - 1.1.1.1/24 -- Laptop(TFTP Server) - 1.1.1.2/24. *Laptop_W11 is running TFTPD64. We can ping back and forth between the management port and the laptop, the laptop is listening on port 69, and everything appears to be good.
We can successfully upload the startup config to the TFTP server on the laptop and into our chosen directory:
#copy startup-config tftp 1.1.1.2 TEST.txt
Then we make similar connections to another 7750 - same model, code, licensing, etc. -- Management port is configured and enabled at 1.1.1.3/24 -- we can ping back and forth successfully - TFTP server is the same.
But, when we use: #copy tftp startup-config 1.1.1.2 TEST.txt = nothing happens? And we get the error:
TFTP Session timed out. Error - can't download startup-config from TFTP server.
Like there is no communication happening - no logs in the TFTP server, nothing - even though both 7750s are the same, there is ICMP communication between both 7750s and the TFTP server, and there are no changes to the settings on the TFTP server.
*These are locally connected - no FWs, Windows FW on the laptop (TFTP server) is allowing tftp
Very odd. Any ideas are greatly appreciated.
