WLAN Global Setup
Displays the current IP address of the wireless controller.
In order to support larger networks, you can configure 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.
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 configure in the timeout field, the entry is deleted.
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.
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
configure in the timeout field, the entry is deleted.
Select either White-list or Black-list.
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 configure in
the timeout field, the entry is deleted.
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.
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 configured 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
(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: 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 traffic, 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 fit within the tunnel.
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.
Enable or disable the client QoS feature. If AP Client QoS is disabled, the Client QoS
configuration remains in place, but any ACLs or DiffServ policies applied to wireless
traffic are not enforced.
The Client QoS feature extends the primary QoS capabilities of the wireless
controller to the wireless domain. More specifically, access control lists (ACLs) and
differentiated service (DiffServ) policies are applied to wireless clients associated to
the AP
