Predownload image of access points

Hello

I was wondering if anyone can shed some light on the process of predownload.

According to the WLC configuration guide:

1. download the new image for the WLC.

2. change the image again to the backup image. (> startup config backup)

3 predownload new image for access points > ap image config predownload {primary | backup} {ap_name | all}

Here I do not know whether to use primary or backup. Is - this view of the PA or WLC.

I mean

the main use that means that the main image WLC is downloaded (which is actually the existing image as a result of step 2)

or

the primary use means any image I download becomes the main image on the AP

4 swap primary and secondary image on AP > config ap image swap {ap_name | all}

5. make sure that all the APs did with the predownload

6. system HH image reset {swap | non-swap} reset-aps [save-config]

Do not know what exactly the swap image is here. If one swaps the image on the AP only or on the controller as well?

I feel, if I followed the guide that my WLC will have the new code as backup and after reset system using the APs swap keyword will return with the new code.

Am I missing something?

Thank you

Hi John,.

the WLC both the AP will review the main image to be the newly uploaded image.

Current/running will be the backup.

Step 2, you mentioned below (startup config backup) just means that if you restart the WLC he starts from the backup image (which is the 'old' in this case).

You can check what is the active (running) and the following boot image on the WLC with the command "See the boot", for example:

(Cisco Controller) > see the boot
Main boot image... 7.0.98.0 (default) (active)
Backup boot image... 6.0.199.0

Then, after using the command 'boot backup config' this will become:

(Cisco Controller) > see the boot
Main boot image... 7.0.98.0 (active)
Backup boot image... (default) 6.0.199.0

Thus, 'start-up' config backup will not backup image to become main... the WLC will start just from the backup image.

On the command 'config ap image predownload' on the WLC, the main / backup is from the point of view WLC:

(Cisco Controller) > predownload config ap image?

Predownload primary an image to a Cisco of the main image of the controller access point.

Predownload backup image to a backup image of the controller Cisco access point.

I hope this helps.

Kind regards

    Additional notes:

    The access point compares his running image with the image running on the controller. If the versions match, access point joins the controller.

    If the versions do not match, the access point compares the version of the backup image, and if they match, the access point swaps main and backup images and recharging and later joined the controller.

  • Unable to create an access point to edge MyRIO

    Hello!

    Today I'm trying to follow this white paper (http://zone.ni.com/reference/en-XX/help/373925B-01/myriohelp/myrio_creating_wireless_networks/) to make my MyRIO Board as access point.

    I tried with the Interface of MAX but when I tried to access the network settings on the Board of Directors, he doesn't show me an infinite spinner with writing something like "network card search...". "(Translation of my poor french"search of NIC in progress... »). instead of the menu on the first image at this link http://digital.ni.com/public.nsf/allkb/627507F4737474F286257CB4007984C6.

    I said I can't do any operation on the interface wlan0 via SSH (no message such as unknown interface wlan0) and the proxy of my company block access to the web configuration of the network card...

    But the main problem is this infinite cone. Why?

    Please help guys...

    Thank you to everyone.

    Hi afghow,

    The message "no network adapter found" could be the result of:

    -Bad IP configuration.

    What is your computer IP address and the cRIO one? (you use DHCP or static?)

    -A problem with your firewall

    Have you tried disabling your firewall in order to access the parameters of myRIO?

  • to convert 1142N AP autonomous lightweight access point

    Hello

    I have 4 1142N access points are all points of light access. Because I don't have a controller, I need to convert to standalone AP.

    I went through document cisco 1142, where it is mentioned that "the access point 1142 doesn't have the default IP address"

    I know procedure to convert offline in which I need to connect ap to the TFTP 10.0.0.1 with the ip address by default, but as for 1142, we do not have the default ip address. What is the procedure to convert offline?

    I have to assign a pool in one of the local switch and connect the ap to these switches with vlan, so she will receive the IP address of the DHCP server?

    But how can we without default IP address? I wonder about this...

    If I did not turn on where I can assign pool dhcp... what should I do?

    Please suggest me to convert 1142 standalone AP ap...

    I will be thankful to get the right answer...

  • Ordered the wrong access point!

    I thought that I had ordered a 1130ag but looks like I ordered a 1131ag LWWAP.

    Please could someone tell me what the difference between a 1130 and 1131. I understand I can load the IOS on the light AP software using a tftp server, but I do not know which exit to load on this subject. 12.3JX, 12.3JA, 12.3JEA, 12.3JEB! can anyone help please? either by the way, I am in the United Kingdom, do not know if this affects image to install. Thank you.

    Hi Paul,.

    This happens all the time, so it shouldn't be a problem :) I'm guessing that you have received this AP - AIR - LAP1131AG - x - K9 LWAPP. When you really wanted this AP - AIR-AP1131G-x-K9 Cisco IOS software. Look at the comparison;

    http://www.Cisco.com/en/us/products/ps6087/products_data_sheet0900aecd801b901c.html

    That being said, you should be good to go with 12.3 (11) JA1.

    Returning to standalone Access Point

    http://www.Cisco.com/en/us/products/HW/wireless/ps430/prod_technical_reference09186a00804fc3dc.html#wp161272

    You can convert an access point of the mode light return to autonomous mode by loading a Cisco IOS version that supports stand-alone mode (Cisco IOS release 12.3 (7) JA or earlier version). If the access point is associated with a controller, you can use the controller to load the version of Cisco IOS. If the access point is not associated with a controller, you can load the version of Cisco IOS using TFTP.

    By using a TFTP server to revert to a previous version

    Follow these steps to return mode LWAPP stand-alone mode by loading a version of Cisco IOS using a TFTP server:

    --------------------------------------------------------------------------------

    Step 1 the IP address of the computer on which the server software runs TFTP should range from 10.0.0.2 to 10.0.0.30.

    Step 2 make sure the PC contains the file access point (for example, c1200-k9w7 - tar.122 - 15.JA.tar for a 1200 Series access point) in the TFTP server folder and the TFTP server is activated.

    Step 3 Rename the access point image file in the folder of the TFTP server c1200-k9w7 - tar.default for a series of 1200 point, c1130-k9w7 - tar.default of access for a series of 1130 access point and c1240-k9w7 - tar.default for a series of 1240 access point.

    Step 4 connect the PC to the access point using an Ethernet category 5 cable (CAT5).

    Step 5 disconnect the power to the access point.

    Step 6 push the MODE button and hold the button while you reconnect power to the access point.

    Step 7 hold the MODE button until the status of the LED turns red (approximately 20 to 30 seconds), then release.

    Step 8 wait until restarting access point, as indicated by the LEDs become green followed the status LED flashes green.

    Step 9 after the access point reboots, reconfigure using the GUI or the CLI.

  • AP 2702i as autonomous access point?

    Hi all

    I can't access that means? you are not able to go to the CONFIG T of the CLI prompt? and if you are in the same subnet as the AP, are you not able to open to the top of the GUI? If you are not able to then, with the command 'show version' on the AP CLI and see if your image is "RCVKW8". If so you will need to convert the same IOS using the method below.

  • 4402 wireless controller and the 1130AG access points

    I have a bunch of 1130AG (35) and 1231 points of access. I just bought a controller 4402 so I could handle these much easier access points. I currently have the offline access points, so I could control. With the wireless in the mix controller, that I have to fix these to light mode or can I leave them offline.

    We know not the operating instructions so I can leave them in stand-alone mode. Most of them is in the rafters in our warehuse, and I didn't have to pull of these if I have to. If I can use them offline, how can I do that?

    Thanks much for any info!

    Hi Dave,.

    A WLC manages autonomous APs.
    So if you want to centralize the management of your APs through the WLC, you will need to convert it to light and enter them on the WLC.

    To convert the lightweight access points, you can choose between several options:

    1. thanks to a specific upgrade tool that you could install on a PC:
    http://www.Cisco.com/en/us/partner/docs/wireless/access_point/conversion/LWAPP/upgrade/guide/lwapnote.html

    2. [the most evolutionary] by WCS, with a model of migration that could apply to several APs:
    http://www.Cisco.com/en/us/docs/wireless/WCS/7.0/Configuration/Guide/7_0apcfg.html#wp1054876

    3. [not in any book] by the following steps:
    3 (a) download the CEC lwapp recovery image and store it on a TFTP server.
    3 (b) Telnet to the stand-alone PA and issuing the following command:
    Archive Download-sw / overwrite/reload tftp: / // [lwapp recovery image file path]

    As a general recommendation, before to convert the lightweight access points, you can be sure that the wired infrastructure behind is ready to direct them to the WLC for recording.
    It's suggestions explained in the link on the above option #1.

    Hope this helps,

  • Help AIR-LAP521-G-E-K9 wireless access point

    Hello everyone,

    is there anyone who can give me guidance on how to configure an access point wireless AIR-LAP521-G-E-K9 offline? I tried to connect to a standard 1 GB switch, feed it with an IP via DHCP, it responds to the PING, but when it comes to detect in the CCA (3.1), it says unable to connect without even asking username and/or password. Try to connect to it via HTTP or HTTPS does not work either.

    Perhaps someone could explain to me what I am doing wrong?

    Thanks in advance.

    Stefano.

    Stefano,

    The 521 AP series can operate in light or autonomous mode. If your AP is currently the light image above we can convert by using tftp. (I suspect it does, as shown in light AIR - LAP number while AIR - AP is generally self-contained)

    The best way to check is to check the details of neighbor of cdp for the version of the software AP (or connect to the console of the AP and issue a 'show version').

    If the software has 'k9w7' in the name, which is autonomous. If she has "k9w8" then it is light. When operating in light you will be not able to telnet/ssh or go to the web page of AP.

    To convert your autonomous access point, please follow the procedure described here:

  • Guest never appears in a 2602i access point

    Hello:

    Today, I converted an access point AIR-CAP2602I-A-K9 to stand-alone using the mode button/tftp, but any IOS Installer (I tried 2 other IOS and also tried to enter Rommon - I am able to change IOS because that the procedure I used is a not any command), I never get to see the prompt so that I can introduce commands to configure the AP. It's as if it hangs after initialization "successfully."

    The only thing I see all the time is the 'normal' console messages, and it displays no error message at all.  It happened before the downgrade.

    That's where stops the PA, but it is not really hung up because the console messages could keep appearing. He simply never gets the PROMT so I can enter a few commands. Not same acept would come.

    Are you sure that you have turned off the flow control settings?

  • Wireless adapter is missing! Access points could not be found.

    Hi guys! I need your help on my ASUS laptop running Windows 8. The wireless adapter had disappeared. I can not connect no.w at access points or find either. I'm just usingLAN cables to connect to the internet. I tried to solve this problem through update, but nothing happens. I check the Device Manager and bluetooth wasn't there. Please see image for your reference. Answers are highly appreciated. Thank YOU YOU in advance. Godspeed.
