IAP205 and IAP305 : cluster issue

  • 1.  IAP205 and IAP305 : cluster issue

    Posted Jul 04, 2017 02:42 PM

    I explain my problem.
    We have an installation with 18 IAP205 and we would like to add 45 IAP305.

     

    I tried to make a model not to disrupt the client's network:
    I use an IAP205 and an IAP305. I would like to form a cluster with two IPAs but I can not ...
    Both IAP205 and 305 have the same code version.
    The IAP205 terminal is the master with the IP address of the virtual controller 172.16.0.240 (physical IP address : 172.16.0.241)
    When I enter the IP address of the virtual controller in the IAP305 terminal (physical IP address 172.16.0.242), I find myself with two virtual controllers (and thus duplicate IP address) ...

    Is there a specific version to be able to form a cluster with these two types of terminals?

     

    How to train the cluster?

     

    Thank you in advance.

     

    Laetitia.

    What version is are you running on the IAP205s?

    If I recall correctly, the current version is:
    - "ArubaInstant_Taurus_6.5.1.0-4.3.1.2_58595" for IAP205
    - "ArubaInstant_Ursa_6.5.1.0-4.3.1.2_58595" for IAP305

    I had already try with the latest version (6.5.3.0) but with exactly the same problem ...

    You should just be able to boot the 305 in the same subnet and it should join the cluster. If that does not work, SSH into the 305 and type "show log system" to get a clue what could be happening.

    Hello,
    I'm sorry, but I'm not competent enough to see what's wrong with the logs ...
    I have attached to you the results of the "show log system" of the IAP305 but also the configuration file of the two IAPs.

    Maybe you can tell me what's wrong ...

    Your main problem is that your IAP cannot obtain the time from an NTP server:

    Jan  1 08:01:10  cli[2254]: <341004> <WARN> |AP AP305-02@172.16.100.60 cli|  Received NTP alert trigger - status is failure, retry - 0, DTLS state - 0  
Jan  1 08:01:11  cli[2254]: <341004> <WARN> |AP AP305-02@172.16.100.60 cli|  Received NTP alert trigger - status is failure, retry - 1, DTLS state - 0

    If NTP is blocked within your network, many things like certificate services will not work..

    Excuse me for not answering earlier ...

    I managed to solve my problem by re-initializing the AP205 in factory configuration. This is a terminal where we do a few tests, perhaps there was a setting that blocked the association of the AP305.

     

    The key is that the cluster between AP205 and AP305 is operational. We are going to do the "real" installation tomorrow at the customer's, I hope not to have to do the same (reset the terminals).

     

    Thank you for your help.
