AP3805i-ROW won't register with V2110 anymore (same VLAN)

    AP's in the same subnet as the physical topology (esa0, PHY, AP Registration checked).
    APs were already registered with EWC (initially deployed with .ova 10.11), but after upgrade to 10.31.x APs won't register anymore.
    APs have regular IPs, respond to ping and can be accessed via ssh;
    # cget config global shows correct lastAcIp

    I have not set any DHCP Option nor DNS entry.
    Is DHCP Option also mandatory with APs in the same subnet as the physical topology?
    We have DHCP relay.

    Here the information from the Wireless Getting Started Guide.....

    Determine the method of AP controller discovery used by the APs to find the controller(s) to which the AP registers to provide network service. The AP supports:

    • SLP-DA Discovery: Configure the segment settings for the DHCP server that provides IP assignment to the APs to include a reference to the SLP-DA to which WLAN controllers are registered. This allows the AP to obtain a list of eligible controllers.

    • DNS: Configure the controller.

    Hi,

    log in to the (SSH) AP and set it to factroy default.
    login:admin
    password:new2day
    #cset f

    Clear the AP in the EWC to be sure and it should be abel again to connect to the EWC.

    Hi Umut,

    have tried that as well, but it does not work.
    AP gets IP, is pingable from EWC and back, but won't register ...

    Try it with a static controller IP just so we know that the problem is the discovery...

    ssh to the AP
    cset authip 1 x.x.x.x
    capply
    csave

    x.x.x.x is the controller IP

    Hi Dusan,

    if this doesn't work please check if somehow the AP went to a older code ..e.g 9.xx maybe this cause that the AP can't get the EWC?

    # cat /etc/ap_version.txt

    Regards
    Umut

    APs were successfully registered with 10.11 and currently still running this code:

    AP3805i-ROW 10.11.03.0004 interactive shell for service personnel only
    # cat /etc/ap_version.txt
    export AP_VERSION=10.11.03.0004
    ...

    V2110 is currently running 10.31.07.0002 and all APs are online. (Option 78 was needed).

    Solved.

    Option 78 was needed.

    Any idea how to enter the second controller in Option 78?

    could you provide a screenshot of your 78 option settings - there is more then one way to do it and I don't want to provide a wrong answer

    Please advise for "Data Entry Byte: Decimal" scenario.
    We entered one controller by setting Values: "1" and then "10" Add + "1" Add + "11" Add + "4" Add being 10.1.11.4 an IP addr of EWC's PHY port. The PHY port of second EWC is 10.1.11.5.
    Each single number in its line, looks like this:
    1
    10
    1
    11
    4

    You can set up the new address right under that one in the array (without another leading 1) so it would look like:

    1
    10
    1
    11
    4
    10
    1
    11
    5

    Hi Dusan,

    I think that the following article will help you.
