Wireless Controller
User Manual
Peer Group ID: In order to support larger networks, you can configure wireless
controllers as peers, with up to 8 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 config ure in the timeout field, 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 configure in the timeout field, the entry is deleted.
AP Failure Status Timeout: This value determines how long to keep an entry in the AP
Authentication Failure Status list. Each entry in the status list shows an age, and when
the age reaches the value you configure i n the timeout field, the entry is deleted.
MAC Authentication Mode: Select the global action to take on wireless clients in the
white-list: Select this option to specify that any wireless clients with MAC addresses that
are specified in the Known Client da tabase, and are not explicitly denied access, are
granted access. If the MAC address is not in the database then the access to the client is
denied.
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 configure in the timeout field, 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 Unified Wireless controller, the
packet size is increased by 20 bytes during transit. This means that clients configured for
1500 byte IP MTU size may exceed the maximum MTU size of exi sting network
infrastructure which is set up to controller and route 1518 (1522 -tagged) byte frames. If
you increase the tunnel IP MTU size, you must also increase the physical MTU of the
ports on which the traffic flows. Note: f any of the following condi tions 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 traffic, which typically has small packets. The
tunneling mode is used only for TCP based protocol s, such as HTTP. This is because the
