  • 1.  PSA: 10.41.14 - AP radio stuck in channel select if PSK length > 48

    Posted 03-10-2019 22:19
    Hi,

    looks like the software has some issues with a PSK that is > 48 characters.

    In that case if the WLAN service is enabled on the AP radio (1 or 2 or both) the radio will stay in scanning and don't provide service.

    Test setup:
    -AP3915i-ROW, AP3825e
    -Country Austria
    -PSK with 49 characters:
    1234567890123456789012345678901234567890123456789
    -WDS & WPAv2-AES WLAN service

    AP log:
    Mar 10 21:41:31 cap: total VNSs /tmp/seccfg_00_0.cfg
    Mar 10 21:41:31 hostapd0: 1552254091.808100: Configuration file: /tmp/seccfg_00_0.cfg

    File from the AP log:

    wpa=2
    wpa_pairwise=CCMP
    wpa_group_rekey=3600
    AP3915i-2#

    I've run into this issue after the upgrade from 10.41.13 to 10.41.14 because my WDS link wasn't working anymore.

    This was also tested it with a normal PSK WLAN service with the same result.

    I'll create a new ticket for this issue by tomorrow.

    We have the same issue.
    I already opened a ticket.

    Anton,

    my ticket# is 01824597 and I've mentioned the open ticket from you.

    Shouldn't require any data as you could reproduce it with only one controller & AP (ROW-Austria) and PSK length of >48

    See article "https://gtacknowledge.extremenetworks.com/articles/Solution/AP-radios-stuck-in-channel-select-if-PSK-length-is-more-than-48-characters"
    Upgrade software to 10.41.14.0009 or higher.
