ERROR: fail to bring ethernet link up

waldvoge
Level 1
Level 1

I have a Cisco 1231 AP

I teach a class on wireless communication

The students have erased flash and now we are going to load an IOS image, however, the ether_init command responds with the following message

ap: ether_init

Initializing ethernet port 0...

Reset ethernet port 0...

Reset done!

link auto-negotiating....

auto-negotiation takes 3745 milli-seconds to complete

auto-negotiate: detect remote fault

ERROR: fail to bring ethernet link up

we cannot load the image with tftp and our ethernet port seems to be dead.

Any ideas
