Here is the output:

I followed this article Edison sent, but it is strange it complains about permission. I am on exec mode, switch config is brand new after 'write erase'. Any thoughts?

Switch#dir cat4000_flash:

You are using the 'delete' command while the link tells you to use 'erase'. Hmm...

Try again :)

Actually I tried the 'erase', but it did not accept it, so I thought 'del' was the only option:

switch#erase cat4000_flash:vlan.dat

^

% Invalid input detected at '^' marker.

Try the command

erase cat4000_flash: without the vlan.dat in it.

More information on that command can be found on the documentation:

http://www.cisco.com/en/US/docs/switches/lan/catalyst4500/12.2/52sg/command/reference/ch2a_ins.html#wp1736308

I did it. I think Cisco could updated that documentation, something is wrong:

I reloaded the switch, now it went directly onto rommon 1>. I if I do a

rommon 3>dir

I see images listed there as below. The one deleted apepars as 'delete' but I hope I should be able to boot using the other one...

Well, you must've typed another command since the command I illustrated does not delete the flash:

type

boot cat4500-entservicesk9-mz.122-40.SG.bin

Hmm...

Do you really have a space on the file name?

cat4500-entservicesk9-mz.122-40.SG.b<>in

try typing

boot cat4500-entservicesk9-mz.122-40.SG.b

if it works, make sure to rename that file to a valid name.

I copied the file exactly as shown on the ouput, but then I got the error message below.

I am positive I did the right command;I got the confirmation stating that "VLan database was deleted". It is very strange this happened.
