I have 4507R i cant delete the vlan.dat from the cat4000bootflah i receive the following
%error deleting cat4000bootflash permission denied
how can i solv it?
Can you please issue a command "dir cat4000_flash:" and confirm me if you only see vlan.dat file there?
If you see only vlan.dat file issue a command ""erase cat4000_flash:"
I believe there is nothing other than 'vlan.dat' file in cat4000_flash:, so that will take care of it. You may need to reload the switch to see the vlans disappear.
