we have a vlan containing all switch management interfaces. I can save all configurations by tftp apart from two C2960-12 with IOS 15 running. All other switches have a IOS 12.2.. When being connected to these two switches, I can't ping the tftp server, but I can ping other servers in the same network segment as the tftp server. I can ping the tftp server from all other switches. The tftp server debugging shows no connection from these two switches. A bit odd. Is there a way to debug the way of the tftp packets through the LAN? They have to pass other switches, as they are cascaded.
Thanks in advance
