I have a couple of 3750 switches that I need to upgrade before I put them on the network. How can I do this with TFTP instead of xmodem because I keep getting an I/O error when trying to use xmodem. The one thing I tried is connecting my PC via Ethernet to my switch, I used IP address 10.10.10.3 on my PC NIC and then used 10.10.10.1 for my VLAN1 on the switch. I could ping the switch form the PC, but I could not ping the PC from the switch. I even tried using 10.10.10.3 as my default gateway on the switch and that did not help either. Can anyone help me out on this or let me know of an easier way that I can upgrade these switches.
