How do I make a Configurable Cisco Switch into a Dumb Switch?

I have a Cisco 2900 XL switch.

What configurations do I need to input to make it a dumb switch.  In other words so that its acts like a nonconfigurable switch? i.e. Dlink linksys etc.

Thanks.

Run to the hardware store: Home Depot, etc and buy a tube of epoxy

Then default the switch:

>http://www.cisco.com/en/US/products/hw/switches/ps607/products_tech_note09186a00800c4546.shtml

Power down the switch
Unplug the power
Fill the console port of the switch with a 1/4 of the tube of epoxy, sit and let dry (24hours)

Plug power back in and you now have a dumb switch.

OK smart guy.

If i connect a dumb switch to the configurable switch it will not work.

Why is this?

Switchport mode trunk

what other configurations do  I need to put into the Port so they can talk and pass data?

are you using a cross-over cable to connect the switches together?

Don JohnstonInstructorCommented:
Actually, before you fill the console port with epoxy, you'll need to:

1) disable spanning-tree (this is impossible on most Cisco switches)
2) disable VTP (once again, pretty much impossible but moot after the next point)
3) disable DTP
4) disable CDP

Why do you want to do this?

I think he is looking for a plug n play type of capability which is possible with managed switches. Atleast i haven't had any issues with doing that for the one at my home.

Yea im using a crossover cable between the dumb switch and the Cisco switch.  The lights stay orange and no data will pass.

how do i configure the Trunk port?

Marius GunnerudSenior Systems EngineerCommented:
to configure trunking:

enable
configure terminal
interface fa0/10 (or whichever interface you are using to connect to the other switch)
switchport trunk encapsulation dot1q
switchport mode trunk

Im not too familiar with this area however i beleive that making the dumb switch to passive mode will allow it to still forward data but do nothing with it

I wasn't trying to be funny, I was actually serious; I do not question the reasoning why one wants to do something. If they want to elaborate on what it is they are trying to accomplish, then great. But I was only providing a solution based on the question.

>If i connect a dumb switch to the configurable switch it will not work
switch to switch you need a crossover, as you have.

>Switchport mode trunk
If you are connecting another dumb switch to the 2900XL, then you do not need this command as the dumb switch does not have the capability of utilizing DTP or 802.1q for that matter.

>what other configurations do  I need to put into the Port so they can talk and pass data? If they are staying orange, then spanning-tree is more than likely in blocking. Do you have a network diagram that you can provide to indicate what it is you are trying to do. How many ports of the dumb switch are you connecting to the 2900XL, or what is it that you are trying to accomplish?

Enable Spanning tree port fast on the port of the cisco Switch and see if it works

From the 2900XL to a dlink switch DGS-1224T.

my goal is to have computer on both switches'
and be able to push and recieve data through a port on one of the switches.

Don JohnstonInstructorCommented:
You shouldn't have to do anything to accomplish that. Just connect the switches together with a crossover cable.

I think rfc1180 answered the question rather nicely.
