AUI interface problem.....

[beatmaker05]

ok, i have just set up a lab and i'm very new at this so please bear with me. i have a 2501 (I know.....it sucks, but it is all i can afford), and it has 3 interfaces:
2 serial, and 1 AUI
but when i type "show ip int brief", i do not see the AUI port listed!
when i want to configure the serial port, i type "int s0", and i am able to assign ip address no problem.
but when i plug the transceiver with crossover cable from AUI port to PC NIC, and type "int e0", it keeps saying "invalid marker", with the ^ symbol pointing to the e.
i am positive i am in the right mode.
but like i said, "show ip int brief" does not even list the router as having an ethernet port......someone told me to do a "copy tftp flash" to update the software version, but how can i do that without an ethernet port?
any ideas? im really stumped....
thanks

Not sure why your not getting the "invalid marker" message. But as for the second question of how to upload an IOS update. You can do it via the console cable and hyperterminal. See this link:

This may be of more help to you if you have access to Cisco IOS images. If you don't have access to any images then this is not going to do you any good.

GNS3 is a cisco emulator if you get an IOS image you can run it and perform router configurations and the like on your computer and don't even need a stack of routers. This is what I use to prototype configuration settings and the like.

You need a transceiver for the AUI port. You will then have an ethernet port to tftp from/to. Post a sh run...

Since you got the 2501, has the ethernet port ever worked? (I take it that you have a transceiver to use on that port.)

[beatmaker05]

no, this is the first time i have tried to use it. i have a crossover cable from my pc nic to the 2501 aui with transceiver. light on nic is on, so is transceiver light. but the problem is, it wont let me type "int e0". keeps saying invalid marker..

Ebay router? If you still have the ebay link, post it.

Burt

 

[burtsbees]

I am not sure if you even need a transceiver for it to show up. Unplug the transceiver and then see what it says.

Burt

 

[beatmaker05]

no, not ebay.

http://www.ciscokits.com/cisco-dual-2501-router-ccna-kit/

unplugged transceiver.....still not showing in "show ip int brief".

just so i understand, i am SUPPOSED to see an ethernet port when i do "show ip int brief". correct?

 

[StaplesMan]

I may be off base but isn't the configuration register suppose to be? 0x2102

config-register 0x2102

im sorry, but i have no clue what your talking about.
can u elaborate please..

 

[burtsbees]

0x42 just means that ip broadcasts do not have net numbers...whatever that means...lol
Perhaps you could be on to something, staples dude...
If you want to load a different IOS on there, you can do it with x-modem in rommon. However, you would want to
rommon1>confreg 3922
rommon2>reset
That will put BAUD to 115,200, which will speed up xmodem as fast as it can go. I use Tera Term, but have used HyperTerminal for xmodem before...this will load an IOS (or anything to flash for that matter) through the console.

Burt

 

[burtsbees]

But yes, you are supposed to see ethernet0

Burt

 

[beatmaker05]

ah, so i guess the port isnt working then?

Try upgrading your IOS and see what happens after that, but they should have tested it prior to selling it.. I would consider contacting them for a replacement.

ok 1 last question. can the 2501 update ios via xmodem? because i obviously cant use the ethernet port to a tftp server. better yet, what way do u recommend? thanx, youve been a big help!
