Computer won't connect to Cisco Gateway

[LadySlinger]

I've mainly been IT Support and am just diving into the deeper waters of the computer world.

A while back my boss discovered that we have an additional Cisco Router in our network closet that we want to utilize. It is provided by an external data business. The External Business has given me the information that is suppose to be included with this router (i.e. Gateway, Subnet Mask, Range of IP Addresses, etc). However after setting everything up, hooking a Cross cable to the Firewall (and yes, the Firewall is configured for this router with a cross over cable to between it and the router), I'm still unable to ping the router after I make the changes to my desktop PC.

Is there any way of directly connecting to this router using the Cross over cable from my PC to the router and view the configurations of the router?

Thank you,
LadySlinger

you can plug a roll over cable into the console port on the router and then you can view the configurations. Connect the rollover to the COM port on your PC. Connect using 9600 and no flowcontrol. This should let you get in, unless it is configured with a password. If it is configured with a password, pending the model, you will power cycle the router, press <break> or <ctrl><break> while it is booting. You should get put into the rommon mode which will be displayed with the following prompt:

>

from this prompt type o/r 0x2142 and press enter. Then type i and press enter. When the router reboots, choose no for initial configuration dialog, press enter to start, type enable at the following prompt

router>enable
router#copy start run
router#show run
router#configure terminal
router(config)#enable secret <password>
router(config)#config-register 0x2102
router(config)#end
router#copy run start

if you need more detailed let me know i can be more specifc and provide you with some links if you like... Erik Rudnick, CCIE No. 9545

You'll need a cisco console cable and connect to the console port to do the previous reply. Here's another useful link:

Also, if you don't have a console cable and you're unsure of the IP address of the router then you may be able to get it via CDP. Connect the router to a cisco switch on your network and log into the switch and do a 'show cdp neighbor detail' and it will tell you all kinds of stuff about the router including what the router thinks is it's ip addresses.
