DHCP on Aironet 1242AG

I configured dhcp server on the Aironet 1242AG. There are two SSID's on the Aironet how can I bind this dhcp server to one of the SSID's so all the clients authenticating to this SSID will get their IP from the DHCP server that I configured on the Aironet?

so long as the DHCP scope matches the network you want the client to get DHCP from,it should work. When the client attempts to get DHCP it will do a subnet broadcast looking for the DHCP server, and the AP should respond.

  • Aironet 1242ag no longer working after software installation

    We killed an aironet 1242AG access point - someone installed the LWAPP software and it
    either got corrupted or the software itself changes the way the device functions dramatically.  In any
    case we want to revert it back to the way it is supposed to be but the web browser interface no longer works and TFTP
    doesn't seem to work either - We've tried a factory default reset but that doesn't do anything.
    Here's an error we're seeing at boot:

  • Need a Floorstand for a Cisco Aironet 1242AG WAP

    Could you please advise us on a good floorstand for a Cisco Aironet 1242AG WAP?
    We need to find a floorstand that would provide an effective mounting solution for our Wireless Access Point (Model Cisco Aironet 1242AG, images of the back and front are below). It should be at least 5 ft high (1.5 m) with pins/knobs or something to mount our WAP. Any ideas? Need answer asap.
    Thank you for your help!!

    Is the floor stand to do surveys or is it for a permanently mounting ? These normally are mounted to the celing tile.

  • "Busiest Clients" report template on Cisco Prime & Aironet 1242AG

    Yesterday I was trying to schedule a "Busiest Clients" report on our Cisco Prime physical appliance (PRIME-NCS-APL-K9, v2.1.0.0.87).
    My goal was to monitor the busiest clients on a couple of old Aironet access-points. These APs have been installed in a branch office of our university that rely on 4 Mb/s SHDSL WAN connectivity and, as you might imagine, some saturation occurs when the classrooms are crowded.
    Unfortunately, all the reports were empty ... there was only a "No data matches the specified criteria for the report” warning inside.
    The Client Statistics task (Administration>Background Tasks) was enabled and I was able to run this report selecting a different floor area ... after a few tries I've discovered that this error occurs only when the old Aironet 1242AG APs are involved. If I select a floor area populated with the newer 1142 and 2602 models, the report template works as intended.
    So, is there a way to fill a "Busiest Clients" report with data fetched from our old Aironet 1242AG APs?
    Our WLC is a Cisco Wireless Services Module 2 Controller for Cisco Catalyst 6500 (WS-SVC-WISM2-K9).
    (Sorry ... my English is a bit rusty)

    Hi,
    Kindly try to restart the Dameon manager with the command line of the server
    1> net stop crmdmgtd
    and then start the daemon manager --> net start crmdmgtd (wait for atleast 20-25 minutes before login back to LMS and also see if any file do exist at location CSCOps\Objects\dmgtd\ready folder).
    Get the output of pdshow after waiting for 20 minutes and stdout.log and stderr.log from CSCOpx\MDC\tomcat\logs.
    Many Thanks,

  • Question on boot image aironet 1242ag

    i am trying to change 5 aironet 1242ag's from LAP to autonomous.  i have tftp'ed an image to the device but i am having a problem getting it to load the image,  if someone has a minute to discuss i would very much appreciate it.
    I can provide details as needed..  thanks

    Converting a Lightweight Access Point Back to Autonomous Mode
    You can convert an access point from lightweight mode back to autonomous mode by loading a Cisco IOS Release that supports autonomous mode (Cisco IOS release 12.3(7)JA or earlier). If the access point is associated to a controller, you can use the controller to load the Cisco IOS release. If the access point is not associated to a controller, you can load the Cisco IOS release using TFTP.
    Note In some LWAPP deployments, the LWAPP controller resides between the access points and the rest of the network. In this topology, all traffic must cross over the controller before communication with network resources, such as a TFTP server, can occur. When converting back to non-LWAPP IOS with an access point that is no longer using the LWAPP protocol, traffic does not cross over the controller to reach the TFTP server.

  • AP Aironet 1242ag with AIR-ANT1728 antenna , extend cable

    Good day and thx in advance for any help.
    I 'm administration an Aironet 1242ag, and we are currently buying an
    AIR-ANT1728
    as antenna. The standard cable for the antenna is 0.9m long, and It could be insufficient for my needs.
    So a few questions:
    Can i extend it ?
    AIR-CAB050LL-R could fit?
    The connectors should be 1 male, 1 female?
    Thank you again
    Francesco

    You can extend it, but you will have some signal loss depending on the length of cable. These antennas have 'N' connectors and the cable will be fine since it has one female and one male 'N' connector. If this will be mounted outside make sure you use coax seal on the connector.

  • Minimum safe distance to a Aironet 1242AG

    To whom it may concern,
    I've been trying to conduct safety studies on RF systems I'm using on a project, one of which is the Cisco Aironet 1242AG. The FCC's OET states that for the 2.45GHz frequency range, an RF exposure of 1mw/(cm^2) is acceptable for non-controlled RF. I ran a few calculations for our Aironet coupled with a high gain antenna (15dBi) and determined the minimum safe distance was 4.2" away from the antenna. However, standard documentation in the Quick Start Guide for the Aironet 1240AG series access point claims the minimum safe distance is 7.9". I'm trying to figure out how that 7.9" figure was arrived at. The high gain antenna in use is omnidirectional with a beam height of + - 8 degrees.
    The answer is important to me because we have our antenna mounted near a place where a human could sit. Part of me wonders if 7.9" was arrived at simply because the FCC OET Bulletin 65 Supplement C mentions devices with external omni-antenna being typically mounted 20cm away from where a human could be (pg.19).
    Any insight would be great to this.
    - jevans

    I think the line "Proper installation of this radio according to the instructions found in this manual will result in user exposure that is substantially below the FCC recommended limits" clarifies the fact that FCC recommended and cisco recommendation is different taking human safety into account.

  • DHCP on Aironet 1142N

    Hi all,
    I'm a novice at this so I do apologize...
    Is it possible to have DHCP enabled on the Aironet 1142n that leases IP Addresses in a different subnet to what the Aironet has? I've basically got an Aironet 1142n with a static IP address (i.e. 10.0.0.1) and I would like all clients that connect to it to receive an IP in a different range (i.e. 192.168.1.xxx) and would also like the Aironet 1142n to act as the DHCP server. Is this possible?
    Thanks!
    Regards,
    -Alf

    Here is a link that explains the dhcp service.

    12.4(10b)JA/JDA on the Aironet 1242.
    The clients should be connected to one of three VLANs - one for staff, one for students and one for guests. I use the Web-Interface of
    the 1242, because I'm not very familiar with IOS cli.
    After assigning the first VLAN to the SSID -> click Accept, assigning the second VLAN to the SSID (overwriting the previous one) -> click Accept,
    assigning the third VLAN to SSID (overwriting again) -> click Accept,  the assignment of VLANs works really fine,
    (the only thing i change on the page is VLAN, the SSID is set to mandatory WPAv2)
    BUT...
    when the 1242 is rebooted (due a building power off or similar) it doesn't work anymore. Clients end up in an endless authentication loop.
    After doing the procedure again from above - assigning all VLANs sequently once, it works fine again !  till next reboot...
    All VLANs have same encryption, cypher, TKIP+AES CCM. On the Cisco-Site I found a command, which i also tried with no success:
    'aaa authorization network default group radius'.
    I also tried to save the working config and load it into the 1242 again, this also did not work.
    It seems that i'm doing something wrong, but what ?
    Thanks for some help,
    Frank

    All you really need to do is make sure the subinterfaces/vlans are created for each VLAN you need, then have radius push down IETF attributes 64, 65, and 81.

  • Interrupting the boot process on an aironet 1242AG AP?

    Does anyone know if there's a trick to this?
    According to the documentation, I'm supposed to be hitting the Esc key when I see the Loading "flash:/[imagename]" ####### ... line, but this doesn't seem to be working.  I've tried hitting the Esc key a lot during those lines, holding it down, hitting it early, hitting it late, hitting it in the middle, and still no joy.  I'm wanting to hit it with something very heavy and hard about now, but I doubt that'll do anything but cause more problems.  Anyone know what I could be doing wrong here?
    I'm trying to break into a handful of malfunctioning 1242AG APs to see if I can get them working, or if they're faulting hardware that's beyond repair.  (So far they're all coming back with: no "IP_ADDR" variable set, so if anyone knows how to set that without breaking out of the boot cycle, that would be helpful too.)

    Matt,
    Press and hold MODE. Apply power and continue to hold for about 30 sec. The AP will try to find a TFTP server, but after failing, you should have a rommon-like prompt (if I am recalling correctly).

  • Cisco Aironet 1242AG Setup

    Hi,  We have a network on an oil rig offshore using a 1242AG for general internet browsing for those staying on the rig, and it works perfectly.  Now we want to expand this and I have a couple of challanges.
    1. We would like to add multiple access points but these will all have to be cabled back to a central switch due to signals being blocked preventing one access point seeing another, so not guaranteed to be able to link wirelessly from one access point ot the next.  How is this best done, is it possible to setup all access points with the same SSID so users can easily move around and be associated with the best access point, or best to configure as individual access points?
    2. Due to having access points available in living quarters, we want to avoid people leaving laptops constantly connected and using up our expensive satellite bandwidth and impacting on the use of others.  Is it possible with the 1242AG top setup a timeout period, where any connections are automatically disconnected?
    This is all quite new to me so any help or comments on the above would be much appreciated.
    Thanks.

    You have two choices:  Autonomous or Controller-based.  With autonomous, in order for you to "enjoy" roaming, you'd need Cisco WLSE or Wireless LAN Services Engine plus you have to configure and manage each APs.  With controller-based you just configure the controller, convert the APs to LWAP (very easy) and off you go.  You can start investigating if it's financially sound to invest in a 4402 series wireless LAN controller.  If you deploy, say, 10 APs, look for the price of the WLC4402-25 to support up to 25 APs.

Not on the AP or WLC but RADIUS can.

  • Aironet 1242AG duel antenna Workgroup Bridge

    I have an Aironet 1242 AG that I have configured as a mobile workgroup bridge. I have noticed when you enable the bridge on Radio0 (G) Radio1 (A) is disabled or cannot be configured as a bride on top. I read it several places in the documentation that it will do this but I haven't seen an explanation as to why. The 1242 is going to be moving throughout a building so if it is possible I need to find a way to configure it so that if Radio0 looses signal it will jump to Radio1 until Radio0 has a good signal again. I can't make any modifications to the stationary broadcasting access points but they are also 1242 access points. If anyone could tell me if this is possible and how to do it or why it is not possible I would be grateful.
    Thanks,
    Matt

    Enabling the Hot standby activates both the Radio. But both the Radios will be activated at a time meaning communication happens simultaneously on both the Radios. One Radio will not act a s a backup Radio for the other.

  • Aironet 1242AG Ethernet error

    Hi
    Im having an issue with my 1242AG AP that i cant seem to find a solution for.
    I was working away configuring RADIUS and it decided to reboot itself, strange enough but then once it started to reload i got the following:
    Reset ethernet port 0...
    then nothing. The status lights are:
    Ethernet - RED
    Radio - OFF
    Status - Light Blue (near white?)
    Ive checked the LED documentation and it say that its an Ethernet error.
    My problem is that this is the 2nd one in as many days that has done this and i dont know how to get it going again.
    Ive done the manual reset (as per manual)and it just sits there doing nothing aswell, always displays the flashfs[0] text then the reset ethernet port 0... then no further.
    Other posts seem to get to the ap> prompt at least to be able to do some sort of config.
    Anybody know of anything to get this going??
    Any help would be appreciated.
    Rob

    Hi Steven
    Thanks for your reply, the ethernet interface is down, when i connect a cross over cable (tried straight through too)from my laptop to the AP, my laptop says thats its interface is down, so that means that the AP interface is also down as there are no status lights at all and the lappy cant see anything at the far end.
    Ive tried the manual reset (holding MODE for 30 sec while powering on, it takes the status light to pink and the radio light to red but still the same, nothing happens except the:
    flashfs[0] checks then the RESET ETHERNET PORT 0....
    It never comes back saying its reset the interface like most other errors ive found on the forum.
    This is the 2nd one thats done this while ive been configuring it? I cant believe that a configuration statement will kill the AP like this?

  • Pass Thru DHCP with Aironet 1231G

    We have 12 - AP-1231G access points in our warehouse with 2 SSID's, both on different VLAN's. We would like to set one of the VLAN/SSID 's to use DHCP from a windows DHCP server.
    Is this possible to do with option 43 or is that only for lightweight AP's ?
    Sho ver: Cisco IOS Software, C1200 Software (C1200-K9W7-M), Version 12.3(8)

    Thanks !!
    will the DHCP server vendor class need to be configured ?
    Also, I am seeing the cmd "ip dhcp relay information trusted" on some forums  - is this also required ?
