Cisco 2900xl Switch - Newbie Help Please

[weweber3]

I have 2 Cisco 2900xl Switches; I have no idea how to connect to these units. Obvioulsy they have a console port (RJ-45), but I do not know the IP address and I do not have a RJ-45 to DB-9 adapter to try to connect via terminal session. Anyone have any ideas?

Thank you.

Those are really the only ways to connect to the switch withoutn having vty capability, sorry.

What is VTY ?

I understand those are the way to connect, is there anyway to find out the IP? or reset it to a defaul IP address?

Thank you.

vty is a virtual terminal - allows you to telnet into a device, once configured properly.

You will have to get a console cable to do anything, unless you have an ip address set, vty set, and know the password.
If you need to recover the password, must connect via the console.

The console cable being an RJ45 to DB9 connector and then a VTY session?

 

[nawlej]

no, then, you get into hyperterminal and configure it through there.

you can also try using

arp -a

on a windows machine and looking for the cisco mac addresses.

do a ping sweep to populate the arp table and then look in the arp table for 000d or cisco mac OUIs

arp -a on windows machine will work

How can I do a ping sweep from the command line?

I believe the default IP address of the switch is
10.0.0.1

If you plug into any port on the switch, and set your computers ip address to be on the same subnet, aka 10.0.0.2, you can go to a web browser and put in 10.0.0.1 and configure the switch.

 

[Phobos1821]

To do a ping sweep, you would ping your subnet.

For example.
192.168.1.0 255.255.255.0 Subnet

Ping 192.168.1.0

Look at the arp table. All hosts should reply to your broadcast.

This is not new, it has been configured before, but I have no idea the IP, etc.
