Section 4 - Advanced WLAN Conguration
Field Description
WLAN Global Setup
IP Address DisplaysthecurrentIPaddressofthewirelesscontroller.
Peer Group ID
In order to support larger networks, you can congure wireless controllers as peers,
withuptoeightcontrollersinacluster(peergroup).Peercontrollerssharesome
information about APs and allow L3 roaming among them. Peers are grouped
according to the group ID.
Client Roam Timeout
This value determines how long to keep an entry in the Associated Client Status list
afteraclienthasdisassociated.Eachentryinthestatuslistshowsanage,andwhen
the age reaches the value you congure in the timeout eld, the entry is deleted.
Ad Hoc Client Status Timeout
This value determines how long to keep an entry in the Ad Hoc Client Status list.
Eachentryinthestatuslistshowsanage,andwhentheagereachesthevalueyou
congure in the timeout eld, the entry is deleted.
AP Failure Status Timeout
This value determines how long to keep an entry in the Ad Failure Client Status list.
Eachentryinthestatuslistshowsanage,andwhentheagereachesthevalueyou
congure in the timeout eld, the entry is deleted.
Client MAC Authentication Select either White-list or Black-list.
RF Scan Status Timeout
ThisvaluedetermineshowlongtokeepanentryintheRFScanStatuslist.Eachentry
in the status list shows an age, and when the age reaches the value you congure in
the timeout eld, the entry is deleted.
Detected Clients Status Timeout
This value determines how long to keep an entry in the Detected Client Status list.
Eachentryinthestatuslistshowsanage,andwhentheagereachesthevalueyou
congure in the timeout eld, the entry is deleted.
Tunnel IP MTU Size
Select the maximum size of an IP packet handled by the network. The MTU is
enforcedonlyontunneledVAPs.WhenIPpacketsaretunneledbetweentheAPsand
the wireless controller, the packet size is increased by 20 bytes during transit. This
meansthatclientsconguredfor1500byteIPMTUsizemayexceedthemaximum
MTUsizeofexistingnetworkinfrastructurewhichissetuptoswitchandroute1518

increasethephysicalMTUoftheportsonwhichthetracows.
Note: if any of the following conditions are true, you do not need to increase the
tunnelIPMTUsize:
• ThewirelessnetworkdoesnotuseL3tunneling.
• The tunneling mode is used only for voice trac, which typically has small
packets.
• ThetunnelingmodeisusedonlyforTCPbasedprotocols,suchasHTTP.Thisis
becausetheAPautomaticallyreducesthemaximumsegmentsizeforallTCP
connections to t within the tunnel.
Cluster Priority
Specify the priority of this controller for the Cluster Controller election.
The wireless controller with highest priority in a cluster becomes the Cluster
Controller. If the priority is the same for all wireless controllers, then the wireless
controller with lowest IP address becomes the Cluster Controller. A priority of
0 means that the wireless controller cannot become the Cluster Controller. The
highest possible priority is 255.
