WLC SNMP traps: Client Deauthenticated

Hi Sir,

I've deployed a WLC4404-100 at a centralized data center, controlling APs (model: LAP1242AG-C-K9) at a remote office in L3 LWAPP transport mode. WLC software version is 4.0.179.8.

Some clients face frequent disconnection. Below is a typical WLC SNMP traps for a client during the time when the client lost IP connectivity (pinging the client from a wired PC resulted in ping loss):

Please advise what the above messages mean. I can't find further information on cisco.com

Thank you.

B.Rgds,

Re: WLC SNMP traps: Client Deauthenticated

Client disconnecting from APs can happen if there is some obstruction between the AP and the client. This obstruction could be due to RF interference. Was a site survey performed before the network was deployed?
