Dumb switch

Quick question I need a dumb switch to plug into my internet providers router.

Going to run that switch in a conference room so outside folks can reach the internet. I have a 2900 series switch and want to turn that into a dumb switch. Is all that is needed is to wipe the config by doing write erase and that is it?

Re: Dumb switch

In addition to erasing the running and saved IOS script, you may also want to erase the vlan.dat file in NVRAM. The commmand for that is "delete flash:vlan.dat". After both this and the "write erase" commands, you should perform a "reload".

See the detailed technote covering just this procedure at: http://www.cisco.com/en/US/products/hw/switches/ps607/products_tech_note09186a00800c4546.shtml#reset_switch

Re: Dumb switch

That should do it. I would double check and make sure HTTP is disabled, VTY lines are off, etc. You might want to consider 'hardening' the switch as well.

Re: Dumb switch

ok sounds good, thank you for help. That sounded a little to easy but I appreciate your help!!!! thank you

Re: Dumb switch

Hi,

Remember to issue #dir and see if it has vlan.dat file, then you should delete this file. This will ensure this dumb switch does not have any previos/old vtp domain/vlan info.

Hope this helps !!

Re: Dumb switch

One other suggestion, if your 2900 series switch supports VTP, you may want to configure it to ignore VTP.
