Internet Speed Upgrade

Greetings everyone.  My Cisco router froze again and it has been doing it since I upgraded my internet speed.  Is there some configuration that I have to change on my router to allow a certain speed?  The problem has been occurring frequently and even has occurred after Cisco replaced my initial router.  Any help would be great.

Have you had your provider replace the Nortel router that the T1 is coming in on? You shouldn't have to change the speed of your router as the speed changed on the Nortel your WAN interface is ethernet and didn't get an upgrade.  
lets see if your WAN interface is logging errors. Issue the following command and post the output.

My issue, though, is that I cannot log in to my router once this happens.  My router goes into ROMMON mode at a certain point.  I was unsuccessful in getting the stack trace this time but previous outputs are here: http://www.experts-exchange.com/Hardware/Networking_Hardware/Routers/Q_23883018.html
which I see you helped me with.

Your interface is running at half duplex and 100 mbps. Find out what the Nortel is and configure it to match. If it went to half duplex it may have failed the negotiation. You may want to hard code the WAN to the below settings. But sheck with your provider and find out what their side is.

Would what you are suggesting actually make the router boot into safe mode?  
0
bkepfordCommented:
Umm shouldn't... Did it make the router reboot?
0
aclaus225Author Commented:
No, what I am asking is if the half duplex and speed of 100 mbps would cause the router to eventually boot into safe mode if that is not what the Nortel router has on it.

matth3wqCommented:
If it doesn't freeze when running by itself i would think the problem is with the vendor and the T1 using Nortel equipment. I am a bit confused why are you placing the router in front of a Nortel router. Should the provider have a DSU/CSU or some other handoff.

bkepfordCommented:
It could cause errors on the line which could cause the line to have a buffer overflow which could cause a problem. But usually no.
But what needs to happen is that both sides needs match regardless.

The Nortel functions as the CSU/DSU.  It is not a router like the Cisco router.

aclaus225Author Commented:
It actually may not be a CSU/DSU, but it is a Nortel SR1001.  That is what the company put in for us when they upgraded our internet speed.

The five minute input/output rate is not near what the router is capable of. If the router is going to Rommon, I would suspect a memory leak or some other type of IOS bug.

What IOS version/feature set are you running? Can you post the output of a "show version".

don,
The router has been changed out and the IOS has changed versions. The only common denominater is the ISPs router.

Can you leave a console cable connected to the router and log the output in hyperterminal? I would like to see what the syslogging shows prior to the problem. I would suspect the router would output some information if it is locking up.

aclaus225Author Commented:
Unfortunately because of the incompetent people that I work under I have no computer that can stay connected to the router.  I am the sys admin for the school and I have to work off a desktop computer so every time an issue comes up with the router I have to go hunt down someone's laptop.  All the other outputs are listed above such as show run, show tech, show proc and even the stack traces.

bkepfordCommented:
Do you have any small 5 port switches? Try sticking that in between the ISP router and your 871. (make sure it is either MDI auto detecting or you use a cross over cable)

billndotnetCommented:
Is there a server on the network somewhere that you could send logging to? Setting an appropriate log level may offer some insight into events leading up to the failure. It won't catch all device crashes, but in the absence of a console log, it would help. Given that you've changed out router devices, there is also the possibility of an externally sourced event that's causing the router to crash.

Alright, I need some kind of configuration code to set up logging this way.  Can someone provide me with something like this?  I mean, the router cannot be connected to a physical computer, so it must do network logging.  Is this even possible?

bkepfordCommented:
Yes
logging on
logging host <IP ADDRESS>
logging trap debug

billndotnetCommented:
Not only possible, but highly recommended as a best practice. Network device memory for logging and history is both limited and volatile, exporting events to a central log server allows for good event collection and troubleshooting, both of individual devices and the network as a whole. Since a device crash, like in your case, wipes the log on the device, external permanant storage is your only option to see if the device is reporting anything before it goes down. I recommend this for all network devices that are capable of logging to a remote host.

bkepford's syslog collector suggestion is a good one for a Windows-centric environment, and you can use vanilla syslogd or (better) syslog-ng for Unix hosts.

How do I set up the Kiwi server to capture the data?  It just seems illogical to me at this point.  I didn't specify a file on the router, so how do I set up Kiwi to do the logging and all the port information?
0
billndotnetCommented:
Syslog, as a protocol, uses udp/514 for transport. A syslog collector is a passive agent, in that it sits on the socket and accepts whatever packets are sent to it. Refer to bkepford's example when configuring your router, making the obvious substitution of <IP Address> for the address of the server on your network hosting the Kiwi collector.

Assuming you downloaded the latest version of Kiwi, once it's running, in either user or service mode, 99% of the configuration is already done for it to perform basic operations. Something as simple as logging into your router, entering and leaving configuration mode, should generate a log message to be transmitted to your collector. Assuming default install options, logs will begin to appear in C:\Program Files\Syslogd\Logs\SyslogCatchAll.txt as they are received.

If messages don't appear on the Kiwi display when you expect them to be, be sure to check for ACLs that may be blocking delivery of udp/514 from the router to the collector. You may need to supply:

logging source-interface <interface name>

If source interface isn't declared, log messages will be sourced from whichever interface is 'closest' to the log collector, from a routing perspective (probably the subnet gateway.)

Alright, from being run ragged I put in the wrong IP Address.  I went in and corrected what IP it was logging to and it works correctly.
