Newbie - 1242AG basic configuration

HSS_cisco — Sat, 03 Jul 2021 22:55:02 GMT

We have just purchased a 1242AG and I am trying to configure it. In the web interface, when information is entered in the express setup and express security screens, and I "apply" it, nothing is saved. Is there something obvious that I am missing?

Thanks,

Alan

Alan,

To be honest - never used it, always configure from the cli. But I have used the GUI on a few occasions - and I would recommend configuring the WALN'S through the sub-menus!

HTH.

If you click Apply in the right place, it SHOULD take it. The Apply buttons are some time a bit confusing, you may have several of them on the same page and you have to click the one that applies to the setting that you are actually changing.

Express setup is an easy place to start from. Try to change the community or AP name for example.

Then if you down on the left menu, try to see if the resulting configuration does take it into consideration...

That is my impression too, it SHOULD take it. I have tried changing the AP name via the Express Setup, but the change does not take. I have also tried setting an SSID via the Express Security screen, but that does not take either. I am wondering whether I have a defective unit.

If the GUI is a no go - configure the AP from the cli, wr mem and reload. If the config is still in there - just a gui issue, if not....hardware issue?

I had avoided the cli because of its complexity. However I have been giving it a try. First Question: one is in exec mode when one first logs in via telnet. So I try to get into privileged exec mode so I can change configuration.

ap>enable

% Error in authentication

How do I avoid that error? (I logged in using the default id/pswd and no the antennae are not turned on yet.)

Hey alan,

Apply might not seem to work correctly in the GUI if you are using a web browser like, mozilla or opera.

Try IE and i hope it works for you.

Re: Newbie - 1242AG basic configuration

HSS_cisco — Thu, 22 May 2008 19:47:36 GMT

Ok,so I tried:

ap>default uid Cisco pwd Cisco

%Invalid input detected at "^" marker

So how is that cmd used?

I am using Firefox on linux. Due to circumstances, it would be very awkward getting this onto Windows to use IE. I hope Cisco didn't go only for IE, their documentation says netscape. In my short experience the web interface seems so thoughly broken as to not be worthwhile attempting to use.

Re: Newbie - 1242AG basic configuration

vunnikri — Thu, 22 May 2008 19:57:17 GMT

cisco supports both IE and netscape, yes you are correct that web interface does not work expected in other browser..

else i will say CLI is the way to go.

At the prompt:-

ap>

type "en" and press return

You should be asked for a password

type "Cisco" the promtpt should then look like

ap#

from here you will be able to configure the access point?

What are you trying to so? I could write your config for you?

HTH.

I tried that:

ap>en

% Error in authentication

What I am trying to do is setup a very basic 2.4GHz access point with WEP 128bit encryption and accepting only a very short list of MAC addresses. I would think this would take a config of only a few lines. If you could do a draft that would be very appreciated.

andrew.prince — Fri, 23 May 2008 15:23:56 GMT

You have a very nice AP - probably running a nice version of code - why would you want to use WEP?

Re: Newbie - 1242AG basic configuration

HSS_cisco — Fri, 23 May 2008 15:25:53 GMT

The AP will be interacting with hardware devices that unfortunately run only WEP.

Did you purchase the LWAPP model or Autonomous ??

Re: Newbie - 1242AG basic configuration

HSS_cisco — Fri, 23 May 2008 15:45:27 GMT

The part number is AIR-AP1242AG-A-K9. And I believe it's the autonomous version but how do I tell for sure? The web interface to the unit shows system software as: c1240-k9w7-tar.124-10b.jA with a version of 12.4(10b)jA

Re: Newbie - 1242AG basic configuration

Ok, I have made headway. Using a combination of the web interface and the CLI, I have the 1242AG partially configured. My question now is in the CLI how does one turn on broadcasting of the SSID so clients can see it?

Re: Newbie - 1242AG basic configuration

vunnikri — Tue, 27 May 2008 13:44:27 GMT

you can turn on broadcast ssid from the following config commands

ap#conf t

Enter configuration commands, one per line. End with CNTL/Z.

ap(config)#dot11 ssid test

ap(config-ssid)#guest-mode

guest-mode is the command that gets the ssid to broadcast.

Re: Newbie - 1242AG basic configuration

HSS_cisco — Tue, 27 May 2008 14:14:56 GMT

Ok, I tried:

ap(config)# dot11 ssid test

ap(config-ssid)# guest-mode

ap(config-ssid)# exit

ap(config)# interface dot11radio 0

ap(config-if)# ssid test

ap(config-if)# channel 8

ap(config-if)# encryption key 1 size 128Bit akey

ap(config-if)# no shutdown

ap(config-if)# exit

I still cannot see the ssid, but from the flashing lights on the 1242AG I can see the radio is active. What am I missing?
