Hi,

We didn't found any information regarding the message in the 3800/5700 WLC documentation but in other products we've found this:.

#     Error Message    AUTHMGR-4-UNAUTH_MOVE, MSGDEF_LIMIT_MEDIUM: [chars] MAC address 
     ([enet]) from [chars] to [chars]

#

Explanation There was an authenticated move on the old IDB. The first [chars] is slow or fast, the second [chars] is the source interface name, the third [chars] is the destination interface name, and [enet] is the MAC address.

#

Recommended Action No action is required.

Does anyone knows the meaning of these messages on the 5760 WLC? These clients are mounted in warehouse stackers, moving in the wharehouse with speeds between 10 and 40 Km/hour and sometimes we have complains of roaming issues. Are this messages related with roaming issues?

Kind regards,

Vasco

Cheers,
Vasco

Hi Vasco,

These messages are related to roaming and it's an expected behaviour.

%AUTHMGR-4-UNAUTH_MOVE is expected to occur when a mac address is moved to another interface by reconnecting network devices.

Thanks,

Ashish
