How to find the @ip connected on a port

Pepette -  
 Nourzo -
Hello,

I would like to inventory the connected devices on my switch by querying it. For example, obtaining the @ip connected to port 15 of my switch number 20.
Is there a specific command? A tool that could help me scan the ports of my switches????

Otherwise, I have to go through the entire network, checking each socket of each device... what a real hassle!!!!

Thanks to everyone for your info!
Laetitia.
Configuration: Cisco and 3com switches

I believe you didn't quite understand my request.
I know the difference between a switch and a hub.
I am familiar with the ranges from Cisco and 3Com.
A DHCP here won't help me since I just need to know which IP is connected to which port of my switch.
But it seems you don't have the info.
Thank you anyway for looking into it :)

Can someone help me, please ?? sniff !!!

Normally Cisco/3-Com/etc... have dedicated software for this kind of information... you should check your boxes to see if you have this management software.

Otherwise, accessing via HTTP isn't a bad idea; you can also find out a lot of things, notably the connections on each port, but for that... you need to enable it on the switch ;-) and the switch must have that option.

The other option is of course connecting to each switch via telnet through a parallel serial cable, but the commands vary from model to model; a Cisco doesn't have the same commands as a D-Link... though they are quite similar nonetheless, but still...

Thank you Tessai,

How can I find out the IP connected on port number 1, for example, once connected via HTTP (graphical mode)?
Or in telnet? In command mode, what command should I type?
For the tools provided with the switch, I don't have any of that in the boxes, I took a quick look on their site but couldn't find anything. :(

mmmm...

I think it depends on your switch; if it's basic, you're light blue chocolate.

Can't you access your switch via an IP address?

Well, I have all kinds. But what do you mean by basic switch??
For your information, I have Cisco 2950, 2900... FX fiber switches... 3Com stuff in all colors... I access them either via Telnet, console port, or HTTP...
So, so???

A basic switch is a switch for individuals, impossible to configure.

I think yours are not and they probably have an entry point via an IP address (http), you type it into your preferred browser and configure, adjust, analyze....

Uh, so it's a hub then??
Anyway, any little idea that could save my life??
Yes, these machines are configured with an IP, a subnet mask, a gateway. No particular VLAN, no spanning tree or anything as ugly as that...
I'm all ears...

A priori, Cisco 2950 are not hubs but switches.

I can't do more.

Don't you have a DHCP server that would give you the address of the switches?

ohoh
 
Hello,
if you access your switches via telnet, you enter the config menu, so you can see in the management menu (if you have the passwords) what is connected on which port.

A question ohoh!
I'm bad at command mode...
I'm currently on my switch in enable mode.
Hmm, what do I do next...?

You have a software called Switch Inventory that does that. I'm looking for the same thing but with a more advanced software, and I'm having trouble finding it.
