Erasing VLAN.DAT file.

Today I tried deleting VLAN.DAT file from a Catalyst 4948 series switch, but I was getting the following error. 

 

%Error deleting cat4000_flash:vlan.dat (Permission denied)

 

I could not find the actual cause of it but I found a work around.  Instead of delete command I used erase command.  One thing to remember is erase command deletes all files ffrom the cat4000_flash.

 

The command syntax is “ erase cat4000_flash:”.  Type yes to confirm that you wanted to erase the cat4000_flash;

 

Hope this will help you.

 

Thank you.
