Hi,

I'm attempting to study for my CCNA and recently bought an old cisco 2514 router with 2 10 mbps ethernet transceivers connected to AUI ports. I was attempting to set up a little network with two hosts, one on either end of the router. All the interfaces have different static IP addresses. One host is a linux box running fedora core 3, the other a windows XP laptop. The linux box has an integrated 10/100/1000 NIC on the motherboard. I think it's a Broadcom.

When I connected my windows laptop, line protocol went up and the router and laptop could ping each other. But the linux box will not connect. The router's AUI0 port has a static IP of 192.168.0.1 netmask 255.255.255.0 and is running at 10 mbps. The linux box has a staic IP of 192.168.0.100 with the same netmask. When I type ifconfig eth0 up, the NIC on the linux box goes up, but the router does not connect and they can't ping each other. I assumed they weren't autonegotiating line speed correctly so I typed

ethtool -s eth0 speed 10 duplex full autoneg off

but that didn't appear to do anything. I have tried switching the AUI interfaces to see if it was the router, and when I connected the windows box to AUI0 line protocol went up, so I'm sure it's not the router's fault. Is there some problem with the syntax of the above command? Or am I doing something else wrong? Any help is appreciated.

can you post yr running config so that we can all take a look.

one more thing, you can try to use the mii-tool in the command line.

You can do a "man mii-too" to see the various options of using this command.If i am not wrong, you can try : mii-tool -F 10baseT-HD to see if it helps.

just my 2 cents

Hey birdie, thanks but your suggestion didn't work. Here is my running-config from the router. I don't think the problem is on the router side but then again I'm very new to Cisco. See anything out of place?

Since you are studying for your CCNA, I'm going to reply with some pointers that should steer you in the right direction in resolving your problem.

In the past, I've had problems with certain NIC cards and auto-negotiation. Setting the speed and duplex at each end always seems to fix this problem.

With the above in mind, checkout the "speed" and "duplex" commands while configuring the associated interface on your cisco router. Use ? after typing speed or duplex.

BTW: This has nothing to do with your speed/duplex problem, but did you notice the following command in your cicso config? no ip routing.

Thx scowles. I set the speed and duplex on the router and the NIC and it worked. Appreciate your help! And yes, i was aware of the no ip routing command in my config... i was trying to get everything conencted before i set up any routes.

Also, I recently read a book that I found immensely helpful in setting up NAT and DHCP on my router... if anyone wants a good primer on configuring cisco routers, check out the O'Reilly cisco Cookbook.
