I do 'write erase' on AP, but configuration remains

news2010a — Sat, 03 Jul 2021 20:09:46 GMT

On my Cisco Access Point Aironet 1200, I do 'write erase', 'reload'. I noticed that some configuration remains(such as BVI IP address).

What am I missing ? Why this configuration remains in spite of 'write erase' and how can I make sure that the whole configuraiton is wiped out from AP 1200 ?

Marion,

Is yoru BVI set to get a DHCP address? If so, when you do a write erase, you do clear the configuration, but the BVI will request an address. If you need to clear the whole config, including it's address, you could try using the GUI, and clear config from there. There are wo options, one keeps the IP on doesnt'.

The static IP and default gateway information are stored in the env_var file. Try to delete that file and reboot again.

Hi, I don't see any setting on DHCP. I pasted the running config configuration below, however, it makes no difference after what happened.

I think I messed up.

I did 'delete flash:env_vars', reload.

Then upon power cycling the device it appears now only with a prompt "ap:". I will need to read more to understand this, but it seems I delete the entire image, right ?

I guess I would need to load image thru tftp at this point, correct ?

Deleting the env_vars file won't delete the image. You can try to factory default the AP then it should be set back to DHCP:
