Hello,
Just need help erasing the entire startup config on a switch running s72033-ipservicesk9-mz.122-18.SXF5.bin
I used write erase, it didn't work.
Please help

Ah. Don't write mem after "clear start". You're rewriting the startup file when you do that.
Do clear start, reboot. No write mem. =)

Are you replying 'Yes', when prompted to save the configuration before rebooting - after the 'write erase' command?
If so, you are copying the running-config (which has the current configuration) back to the startup-config. In other words, you are undoing the 'write erase' process.

Did you try erase startup-config command?

I did erase start.
The system took the command, i write mem, i reloaded; startup config still there.

Thanks a lot John. You saved me. worked perfectly.
All config gone except vlan config.
200 RM_VIP_10.70.63.0/24 active
201 LDAP_VIP_10.66.132.0/24 active

Great! If you want the vlans deleted, you'll need to delete the vlan.dat file in flash:
Switch# del flash:vlan.dat
Then reload the switch and your vlans will be gone also.

I use "clear start".
04-30-2009 08:28 AM
Write erase will clear out nvram. Since you said it's a switch, what are you trying to clear? If you do a "dir nvram:?" do you see a "nvram:startup-config" listed?
HTH,
John

This worked fine.
My mistake was the fact that after del nvram:startup-config, i was doing wr mem again.
04-30-2009 09:17 AM
John,
This is what is listed
Directory of nvram:/
1918 -rw- 19750
1919 ---- 24
1920 -rw- 19750
1 ---- 4
2 ---- 36
3 -rw- 0
04-30-2009 09:19 AM
Do this:
Switch#wr erase
Hit enter to confirm. Reboot. The switch should come up and ask if you want to enter the initial configuration mode. You're ALWAYS going to have a startup file, it's just cleared to defaults when you erase it.
HTH,
John
