Preventing Local Routing between Clients
If you have security and traffic management policies defined in upstream devices, you can disable routing
traffic between two clients connected to the same W-IAP on different VLANs. When local routing is disabled,
the clients can connect to the Internet but cannot communicate with each other, and the routing traffic
between the clients is sent to the upstream device to make the forwarding decision.
You can disable local routing through the Instant UI or CLI.
In the Instant UI
To disable local routing:
1. Navigate to System>General>Show advanced options.
2. From the Deny local routing drop-down list, select Enabled to prevent local routing traffic between two
clients connected to a W-IAP on different VLANs.
3. Click OK.
In the CLI
To disable local routing:
(Instant AP)(config)# deny-local-routing
(Instant AP)(config)# end
(Instant AP)# commit apply
To deny local routing for the WLAN SSID clients:
(Instant AP)(config)# wlan ssid-profile <ssid-profile>
(Instant AP) (SSID Profile <ssid-profile>)# deny-local-routing
(Instant AP) (SSID Profile <ssid-profile>)# end
(Instant AP)# commit apply
Enabling Dynamic CPU Management
W-IAPs perform various functions such as wireless client connectivity and traffic flows, wired client connectivity
and traffic flows, wireless security, network management, and location tracking. Like with any network
element, a W-IAP can be subject to heavy loads. In such a scenario, it is important to prioritize the platform
resources across different functions. Typically, the W-IAPs manage resources automatically in real-time.
However, under special circumstances, if dynamic resource management needs to be enforced or disabled
altogether, the dynamic CPU management feature settings can be modified.
You can configure the dynamic CPU management feature by using the Instant UI or CLI.
In the Instant UI
To enable or disable the management plane protection:
1. Click System > General>Show Advanced Options.
2. Select any of the following options from the Dynamic CPU Management drop-down list.
n Automatic—When selected, the CPU management is enabled or disabled automatically during run-
time. This decision is based on real-time load calculations taking into account all different functions that
the CPU needs to perform. This is the default and recommended option.
n Always disabled on all APs—When selected, this setting manually disables CPU management on all
APs, typically for small networks. This setting protects user experience.
n Always enabled on APs—When selected, the client and network management functions are protected.
This setting helps in large networks with high client density.
3. Click OK.
