Cisco 1200 series upgrade failure

I have a Cisco 1200 Series (AIR-AP1231G-A-K9) access point, I have been upgrading these models to lightweight mode but are having issues with one in particular, this access point keeps "rebooting" itself, I am assuming that the upgrade faild, how can I get the access point upgraded?
Here is a capture.

I might have an answer for you... or I might be COMPLETELY WRONG
If it isn't just a "failed" upgrade, as in you've tried the upgrade again and it still is happening.... I was reading something about older APs not have a Manufacturing-installed certificate (MIC) and these AP's generating a Self-signed Certificate (SSC).
The error you have is referring to SSC so I'm writing this as if you have not had to previously do this step for your other conversions.
I believe a couple of things needs to happen for SSC AP's.
1) Must enable controller to accept self-signed certificated.
Security > AAA > AP Polices > Accept Self Signed Certificate > Apply
2) Add AP to Authorization List in Security > AAA > AP Polices > Add AP To Authrorization List
Enter MAC Address of the AP
Certificate type = SSC
SHA1 Key Hash can be obtained from the controller by issueing this command:
"debug pm pki enable"
Look for the line: sshpmGetIssuerHandles: SSC Key Hash is XXXXXXXXXXXXXXXXXXXXXXXXXX
I believe you use the XXXXXXXXXXXXXXXXXXXXX as the SHA1 Key Hash.
3) If required, you may also need to add the AP MAC Address in the Mac-Filter: Security > AAA > MAC Filtering > New >
Hopefully its either a reload of the software or this SSC thing that fixes the problem....

  • The maximum cable distance from antenna and Cisco 1200 series.

    Hello all!
    I?m using the Cisco 1200 Access Points Series with two 2.2dBi dipole antennas. I have read the installation guide for that Access Points and that can be installed with the antennas in separated places. But this guide didn't mention the maximum distance for the antenna cable...
    Somebody here can say me this maximum distance?
    Had somebody here made this kind of antenna installation with cable?
    Thanks.

    Oh Yeah!, I absolutely agree on "shorter is way better"
    Given any chance / choice at all, I'd try to keep the cable length under 25 feet. If the option is available for a NEMA cabinet to get the cable shorter, I'd probably do that too.
    Since it's good practice to use a chunk of fiber optic cabling between the external stuff and the inside network, you may as well put the AP as close to the antennas as possible and convert the copper to fiber for the long haul.
    You get some lightning protection (at least you won't smoke all of the systems sitting on your LAN) and better signal strength (and probably signal quality too).
    For something like a 200' run, if forced to do it (we're talking "gun to the head" forced here), I'd probably be looking for something like Andrew LDF4-50 1/2" Heliax with probably a weeeeee bit O' amp tossed in for good measure.
    That would also imply that the system would also have to be re-certified, because of the non-standard components ...and a pretty good budget to boot.
    Sometimes you gotta do what you gotta do.

  • Symbol Netvision Phone w/Cisco 1200 series Access Point

    I am running 802.11b access point my phone can associate and get an ip address from my call manager but I keep getting "not registered" "registered". I and then I lose association to the access point. I have 2 vlans on one access point one for voice and one for data. Please let me know if someone has a work around or a fix.
    Stan

    Stan,
    Sounds like you have an interference problem.
    What did your site survey show up in terms of other AP's and overlapping coverage areas ? Try a new channel that has the 2 channel separation from other busy channels and maybe even try a new/better placement of the AP
    effectivly what you have now is the equivalent of pulling out the cable and plugging it back in constantly on a standard IP phone this means you will not be able to make calls
    What firmware you running on the AP ?

  • Cisco 1200 as bridge

    Hi everyone
    I am about to use Cisco 1200 series AP as bridge , but I have seen and I have compared it with Cisco 1300 and 1400 outdoor models , and I saw that 1200 is mainly for indoor (LW).
    Now the question is :
    1. Can I use it as outdoor bridge for Point to Point linking ?
    2. What will be maximum distance with reflector grid antennas (and patch antennas)?
    3. If in practice , is it stabile ?
    Thank you

    Again I stress I can only go by what I'd install in the UK so it may not be applicable wherever you are! Also, I always try and avoid mixing vendors equipment if at all possible so I would use either one of two Cisco antenna, I've also listed antenna cables, use the shortest you can:
    AIR-ANT1949 Yagi mast mount 2MB at 29.49 km.
    AIR-ANT3338 Solid Dish 2MB at 42.62 km.
    AIR-CAB020LL-R 6m antenna cable 1.3db loss
    AIR-CAB050LL-R 15m antenna cable 3.4db loss
    AIR-CAB100ULL-R 30m antenna cable 4.4db loss
    Ranges and throughputs are Cisco's, you may find the biggest problem is clear line of sight over that sort of distance.

  • Need a tool for flash backup on Cisco 2821 series routers

    Hello Folks,
    We have around 1200-1500 cisco 2821 series routers on those we are performing the hardware upgrade so we are taking the backup of all the files available in the flash of all the routers, we just want to know is there any trusted tool available to make this task easy to schedule and take the backups.
    Please let me know if you know any tool name.
    Thanks,
    Raja.

    Sorry, I don't know any tool that makes a backup of the whole flash...
    You could fo it with from ios cli maybe execute it automatically...
    To flash:
    archive tar /create flash:/backup.tar flash:/
    copying directly to ftp should also work:
    archive tar /create ftp://test:[email protected]/backup.tar flash:/

  • Recomended ios for 1200 series?

    Any suggestions for most stable and bugfree ios to use on the AP1200 series?
    For me it looks like the 12.3(8)JEA3 should be ok after reading about caveats in the release notes. Only something about shared authentication in non-native vlans and two other minor things. Our setup has 8 ssids with 4 of them with wpa-psk authentication that works ok with this version.
    Its a little confusing wich version to choose with all that numbers and release dates.

    Only some versions can be upgraded:
    For all IOS-based 1200  series modular access point (1200/1220 Cisco IOS Software Upgrade, 1210  and 1230 AP) platforms, it depends on the radio:
    –if 802.11G, MP21G and MP31G are supported
    –if 802.11A, RM21A and RM22A are supported
    The 1200 series access points can be upgraded with any combination of supported radios: G only, A only, or both G and A.

    What I notice in the original post is this error
    ARP: address resolution for 10.0.0.2 timed out.
    which says that the router is looking for the 10.0.0.2 server but not getting response to its arp request. Can the original poster clarify for us how the device that has the image file is connected to the router that has the problem? Also what kind of device is 10.0.0.2? Is it a PC running TFTP server software or is it something else?

  • Using CLI to enter Mac local list on 1200 Series

    I have a number of 1200 series Ap's that are set up for MAC Authentication based on a local list only. From the GUI these addresses are entered from the Advanced Security Screen.
    I wnt to find a method for entering them from the CLI but am running into a problem with the level 7 passwords that seem to be automaticly applied when the MAC addresses are added from the GUI.
    If I enter MAC 0011.22aa.33ff from the GUI and then look at the config from the CLI it looks like this:
    username xxx password xxxx
    username xxxx autocommand exit
    how do I do this from the CLI?

    Hi,
    I think if you need to enter lots of MAC Addresses into AP, the fastest way is to use CLI.
    Refer to the following doc on how to configure MAC from CLI. Look under "Local Authenticator Access Point - Step 11"
    http://www.cisco.com/en/US/partner/products/hw/wireless/ps4570/products_configuration_guide_chapter09186a0080341e72.html#wp1039558
    If authentication is purely done via MAC, then you can do like the following example:
    AP#config t
    AP(config-radsrv)# user xxx password xxx group clerks mac-auth-only
    Probably you need to use notepad to list all MAC (as username & password), then copy &paste to your AP's CLI.
    Hope this helps.

  • 1200 Series - Tagged Management VLAN Traffic

    Hi,
    As per my understanding the 1200 Series Access points running IOS (12.2(15)XR) send the management traffic (RADIUS,Accouting NTP etc) un-tagged i.e. using VLAN 1.
    As per our current setup, we assign this un-tagged traffic to a different VLAN (by changing native vlan to x for the Trunk Port) on the cisco switch.
    Is it possible to configure the Access Point to send Management Traffic as tagged with a particular VLAN id ? (Similar to what it does for Wireless Traffic, when SSID are associated to specific VLANs)
    We are trying to set this up with a 3-Com 4400 series switch i have been unable to configure the 3-Com switch, so that it can assign the untagged traffic to different VLAN instead of VLAN 1.
    Regards \\ Naman

    Changing the Native VLAN doesn't make a difference. I can create any VLAN and make it native but management traffic is still being sent un-tagged.
    Below was the setup i tested
    AP--->Trunk Link<->Switch Port(Native VLAN=15)
    Switch Port --->Trunk Link<->Router with VLAN15
    I can make any VLAN as native VLAN on the AP and it doesn't effect the functionality as long as the Switch Native VLAN matches to the corresponding VLAN on the router.

  • Specific OID for A radio modules on 1200 series access points

    Is there a specific OID for A radio module cards of the following type:
    Flap - AIR-RM21A-A-K9
    Dipoles - AIR-RM22A-A-K9

    No switches in Cisco's current product line provide enough power to support both radio modules in the 1200 series. The (now optional) power injector for the 1200 will provide enough inline power for both radios, if that is an acceptible option.
    Cisco has plans for several switches that will be able to provide inline power to both radios, but I am not aware of ETA's on these.
