After updating my C3750X 48PF-S to IOS 15.2.4E10 I find myself in a debugging loop.
I thought it was my IOS that was corrupted. I re-downloaded it and uploaded via XMODEM.
Note that before using XMODEM, I tried to use TFTP in ROMMON but I got the error : The "MAC_ADDR" environment variable is not set.
I have never seen this error before. Any idea of how I can get out of it ?
