EMC No connection to Wireless Controllers

    As the title states, I can't get EMC to talk to our C5210 controllers via the secure connection

    They're talking fine via SNMP but thats it.

    When I go into the Wireless manager, it states invalid shared secret or connection loss.

    I've checked and rechecked the secret and this is correct, I even changed it but made no difference.

    I have since deleted and rediscovered the wireless controllers but they still dont sync correctly.

    EMC is running 8.1.4.40 and the C5210s are running 10.41.08.0012

    Any ideas are appreciated.

    Thanks
    Ian

    Hey Ian,

    in short you'd need to enable another cipher via ssh on the controller...

    secureconnection
    message-bus-ciphers AES128-SHA256 3
    apply

    But take a look into the full post and leave a like for Ryan who came up with the answer....
