3750x Management Port - No Connection in SWITCH: mode

Unanswered Question
Jun 20th, 2012

Hi Guys,

I'm trying to get an IP_ADDR set on the management port in SWITCH: mode but for some reason the port seems disabled. PC shows connection unplugged. MGMT_INIT is not a valid command (not listed under '?' ). Bootloader version is 12.2(53R)SE2 FC1. Any ideas?

Thanks for the reply Reza. I should have clarified I'm in recovery mode (assume no IOS). The port works in the CLI but not in rommon/switch: mode.

If you are in recovery mode, than this is not going to work.  You would need to use Xmodem to load a new version of IOS.

once the IOS is completely loaded than you can use the Ethernet port.
