BleepingComputer.com: Finding configuration IP address for a switch

Hi everyone

Ok. I have a CISCO Catalyst Express 500G switch on my network. The person who set the network up (before I was here) neglected to make note of the configuration IP for it. That wasn't a problem until now (I need to change a setting on the switch). I have NO idea how to find it out. I have:

checked the arp logs of several computers.
looked in the DHCP list (its not there so I'm assuming it was statically assigned)
manually tried all the addresses in the block we use (192.168.1.1-254)
The stupid 500G doesn't have a console port
I dont want to erase all the settings (because I dont know what they are!)

I have the MAC address but that seems to be less helpful then I thought it would be (RARP requesting doesnt seem to be an option)

How do I find out the config IP address for the stupid switch!

Thank you all SO MUCH in advance for your help -- really banging my head against the wall on this one.

I think it usually the same as your default gateway address.

From a cmd prompt type -> ipconfig <enter>

From a web browser enter the ip address of your Default Gateway.

Thanks for the suggestion Chuck. THe default gateway is not the switch, however. The default gateway is the router. Switches are layer 2 devices -- the IP address is ONLY for management purposes, hence why it isn't ever cropping up in ARP tables, nothing looks for it. Traffic doesn't consider the switch to be a stop (hence why tracert wont show it).

Hi, I think in this case, you just need a MAC scanner, which may be very helpufl. Install it on your computer and start scanning, you can get a list.

RARP would be your route here. Lisa suggestion is quite good. You need to try it to acquire the IP address of the manageable switch.
