Chapter 3 Configuring Ports and Interfaces
Configuring a 4400 Series Controller to Support More Than 48 Access Points
Step 5
Enter the appropriate interface parameters.
Step 6
To make the interface an AP-manager interface, check the Enable Dynamic AP Management check
box.

Step 7
Click Save Configuration to save your settings.
Step 8
Repeat this procedure for each additional AP-manager interface that you want to create.
Connecting Additional Ports
To support more than 48 access points with a 4400 series controller in Layer 2 mode, you must connect
more controller ports to individual broadcast domains that are completely separated.

provides
an example in which each controller port is connected to an individual switch.
VLANs 992, 993, and 994 (used here as VLAN examples) are access VLANs, and you can assign them
any VLAN IDs that you choose. An IP address is not allocated to these VLANs, and these ports are
access ports only. To connect additional access points, assign the access port connecting the access point
to VLAN 992, 993, or 994. The access point then joins the controller using that isolated VLAN with
Layer 2 LWAPP. All Layer 2 LWAPP traffic received on ports 2, 3, and 4 egresses the management port
(configured as port 1) on VLAN 250 with a dot1q tag of 250.

With a Layer 2 LWAPP configuration, you should distribute access points across VLANs 250, 992, 993,
and 994 manually. Ideally, you should distribute 25 access points per port to balance a total of 100 access
points. If you have less than 100 access points, divide the number of access points by 4 and distribute
that number. For example, 48 total access points divided by 4 equals 12 access points per 4404 port. You
could connect 48 access points to port 1, 48 to port 2, and only 2 to port 3, but this unbalanced
distribution does not provide the best throughput performance for wireless clients and is not
recommended.

It does not matter where you connect ports 2, 3, and 4 as long as they can communicate with the access
points configured for their isolated VLANs. If VLAN 250 is a widely used infrastructure VLAN within
your network and you notice network congestion, redistribute all of the access points connected to
VLAN 250 to ports 2, 3, and 4. Port 1 still remains connected to VLAN 250 as the management network
interface but transports data only from wireless clients proxied by the controller.
