Router Config Problem

Can you post the config of Cisco 2514 once?

Thats normal.

You need to troubleshoot why the line protocol doesn't come up. Don't worry about the IP info and routing. You aren't getting that far.

Check your ethernet media transceiver on the 2514. Check the cabling. Swap the transceivers around.

The reason the 2nd route isn't there is the interface isn't up. You need to get the interface up first.

I swapped the tranceiver that works on eth0 to eth1 and it does not come up. I also swapped the cable that works on eth0. The interface is up but the line is down.

The config on the 2514 currently consists of the ip address and mask. I wanted to keep it simple to troubleshoot this problem.

Sounds like a bad hardware port then.. Probably either the receiver or transmit pair is bad, especially if you already swapped the transceiver.

Yeah, but what I'm saying is that you are stuck at Layer-1 problems, long before you to get to Layer-3 configs.

There's not a whole lot to configure at the layer-1 level, let alone anything at the upper layers that can mess it up.

This sounds nuts but I even tried another 2514 and the same thing happens. I even tried these two addresses on the ether ports:

I guess at this point I am asking the wrong question. The question should be:

How do I configure a Cisco 2514 with 192.168.1.1 255.255.255.0 on Eth0 and 192.168.2.1 255.255.255.0 on Eth1 and make it route ip between the two interfaces? Maybe I am missing something basic here.

tman,

If the physical interface comes up, but the line protocol stays down, this usually indicates a Layer 1 or 2 issue (more likely layer 2). You're not even hitting Layer 3 reachability yet, so it's best to not worry about that at this point. If you're plugging these in back-to- back, are you using a cross-over cable? Also, it looks like you're connecting FastEthernet to Ethernet. Make sure to hard-code the speed and duplex on both routers: Speed at 10Mbps (Ethernet being the lowest common denominator), duplex at half or full.

HTH, neteng

The 2514 has two AUI ports so there's no issue with speed or duplex - it's 10M and half duplex whether you like it or not. A crossover cable may be required. Since there must be transceivers involved, we need to know whether the link comes up or not - should be lights on the transceivers to say so.

Thanks guys. I finally broke the code. I was not using a xover to connect laptop to router. What through me even further off was that one of them worked on eth0 but not on eth1. I put another kind of tranceiver on eth1 and it worked with an xover cable. I flipped the little switch on the transceiver on eth0 and now it needs an xover cable but it works. Sheeeeeeeeeeesh!

You should also be able to turn off keepalives on the Ethernet interfaces...this will bring them up without external carrier from another device. Nice way to test the physical interfaces/configs without having to connect something to them.

Hello tman,

What is the output of "show int e1"?
