Cisco Router Upgrade

About a week ago I was trying to upgrade my Cisco Router's IOS and I did this successfully.  In posting on here to find out what to delete it was suggested to me that I should get more memory for this router, but I am not sure what I am supposed to be looking at.  
Additionally, my router just stopped working today and by manually turning it off and on I got it to work successfully.  It does not respond to inside requests (telnet to the router) or outside requests (we run a small website that is translated through the router to a public address).  Does this have anything to do with memory filling up?  
I am adding the specs from the router if that helps.  
Cisco 871 (MPC8272) processor (revision 0x200) with 118784K/12288K bytes of memo
ry.
128K bytes of non-volatile configuration memory.
24576K bytes of processor board System flash (Intel Strataflash)

If you were able to load the flash successfully it should be fine. Can you connect to the router with a console cable(blue cable that goes from the router to a 9pin serial)?
Even though you can't get into it is it still forwarding traffic and people still get to the internal web server?

It stops working completely.  My internal traffic that is going to internal addresses work fine, since they are serviced by my Domain Controller not by the router.  My external users (those wanting to go to the website) do not have access to it.  When I restart the router it works just fine.  Unfortunately my boss did not see fit for me to have a laptop so I have no way to use a console cable to get into the router.

Is it working now then? Does it start to work and then fail?

The router works for somewhere between 3 and 5 days and then stops all of a sudden.  I do not have a computer able to go into the console so I just have to reboot the router to get it to work again.  
It is currently working because I rebooted it.

bkepfordCommented:
According to your specs you have 128 RAM and 24 flash which is what the image you have requires.
Since that is the event that seems to have triggered this problem I would redownload the image from Cisco.com, erase your flash and tftp the new image your router and reload.

I was having the issue before I ever upgraded.  I upgraded the image because I thought that it would resolve the issue but it didn't.  The previous image which was on the router for roughly a year had the same issue after my upgrade from a 768k connection to a T-1 connection.

What device is the T1 connected to and then how is it connected to the 871?
0
 
aclaus225Author Commented:
The T1 is connected to a Nortel router and the Nortel is connected to the WAN port of the 871.

bkepfordCommented:
If you do a show interface on the WAN port are their any errors on the port?
 
0
 
aclaus225Author Commented:
The router is perfectly functioning right now.  I am not sure what the WAN port interface is, so I am including the show int command.

bkepfordCommented:
Nothing on the WAN interface. Can you post the output of  "show proc"
Also go ahead and turn on logging
router#conf t
router(config)#logging on
router(config)#logging buffered 4096 7
router(config)#exit
router#show logging
Or you could monitor the messages that may be coming in though the console by entering
router#terminal monitor
to stop recieving console messages
router#terminal no monitor

Hmm that looks fine. Can you post your router configuration?

Everything looks good. If you have a service contract with Cisco I would open a TAC case and see if they want to replace your hardware.

What is happening is your router is rebooting into rommon mode which is kind of like safe mode it doesn't have any IP addresses configured.
Type in "show boot" and paste in that information along sith "show flash"

aclaus225Author Commented:
I forced the router to do that this morning because the guy from Cisco needed the information.  I mean, I guess I didn't force it, but that is what command I was told to carry out.  If I do the show boot and show flash now it will not show the error.

My bad show boot is a switch command
do "show hardware" We are looking for your system image file name

Alright, Cisco is replacing this router.  Is there an easy way to configuring the new router with the old configuration, or will I have to manually do everything?
0
 
bkepfordCommented:
Copy your startup-config file and then get the IOS version that you need.
"copy startup-config tftp://<IP of TFTP>/startup-config "
Once you get your new router console into it, setup the ip address info and then
"copy tftp://<IP of TFTP>/startup-config startup-config"
Also delete the current IOS and upgrade to the new one.
This is pretty much as automated as you get.
