I was able to download the running-conf file using TFTP, but after correcting a end of file erro I can't seem to upload the config back on the divice using the "copy tftp://192.167.X.XX/ws-ce520-8pc-k9-confg running-config" Command thru my CLI. any ideas? the X.XX is masking my ip configuration, but the TFTP ip is on the same subnet and correct interface/IP. Why can't I communicate with the switch & TFTP Bi-directionally?
