Discussion on:

10 commands you should master when working with the Cisco IOS

Now how do I access the firmware in my network card.I suspect that it is very similar.

If I recall from a few years ago, take laptop to router, obtain special cable from RJ45 on laptop to serial 9 pin on the router - connect and telnet into the router. You need router name and password for admin functions. Happy exploring.

You can easily find rollover cables on eBay for a reasonable price.

we got stacks of them heh

I've inherited 2 2811's. Supposedly they are both using the same credentials for admin access.

One of them will let me admin via the web interface and SSH, and the other will only work with SSH... it rejects the credentials when trying to access the web interface.

How can I get around this?

Thanks,

several different things could be going on, such as an access list preventing access, etc. You are probably better off accessing these via ssh anyway. Try looking at the usernames, and at the login section of "show running config". you may also need to check if web access is on:
ip http server

IOS commands are great learning tools for the Cisco professional. I teach Cisco and find that more IOS commands known by the IT professional the better his or her command of the router will be.

I use 'show log' and 'show cdp neighbor' more frequently than debug.

I saw another option that I have yet to try.

Once you make your configuration changes, you need to save those changes. This command copies the configuration in RAM that you have been modifying to the configuration in flash. By copying it to flash, it will be saved when the router is powered off and restarted.

A shortcut for this command is wr (short for write memory).
