Configuring Cisco 2511

Without being able to telnet to it, you'll have to dig out the console cable, and hook the console port up to a serial port on your laptop/computer. Run up a term program, 9600 baud, 8N1, and issue the correct commands.

Its probably configured on the Ethernet 0 interface, something like

enable conf term int ethernet 0 ip address 10.10.10.10 255.255.0.0 end write mem

would work.

Sure, Cisco has lots of them online..

Here's the basic config manual for a 2511..

Note, you don't need a 2511 specific manual for 99.99% of what you need to do, although sometimes starting out, its easier to see commands tailored exactly for your enviornment.

Pull it off on to its own hub, put a PC with a static address in the same subnet, and then telnet to it.

It's already off the network, so just get a private hub and another PC, and just make the telnet connection.

Or, use the console cable, as others have suggested..

Command

telnet (IP address) enter password Router>enable enter enable password Router # Configure terminal interface ethernet 0 ip address x.x.x.x 255.255.0.0 (or whatever mask)

Don't forget to open up your interface by doing a 'no shut' after your imput of the IP address. It's amazing how many people I've seen make that mistake!
