Make sure that the Cisco wireless LAN controller DS port is connected to the network. Use
Step 1
the CLI, web-browser interface, or Cisco Prime Infrastructure procedures as described in the
appropriate Cisco wireless LAN controller guide.
a. Make sure that access points have Layer 3 connectivity to the Cisco wireless LAN controller
Management and AP-Manager Interface.
b. Configure the switch to which your access point is to attach. See the Cisco Wireless LAN
Controller Configuration Guide for the release you are using, for additional information.
c. Set the Cisco wireless LAN controller as the master so that new access points always join with
it.
d. Make sure DHCP is enabled on the network. The access point must receive its IP address
through DHCP.
e. CAPWAP UDP ports must not be blocked in the network.
f. The access point must be able to find the IP address of the controller. This can be
accomplished using DHCP, DNS, or IP subnet broadcast. This guide describes the DHCP
method to convey the controller IP address. For other methods, refer to the product
documentation. See also the
information.
The access point requires a Gigabit Ethernet (GbE) link to prevent the Ethernet port from
Note
becoming a bottleneck for traffic because wireless traffic speeds exceed transmit speeds
of a 10/100 Ethernet port.
Apply power to the access point. See
Step 2
a. As the access point attempts to connect to the controller, the LED cycles through a green, red,
and amber sequence, which can take up to 5 minutes.
If the access point remains in this mode for more than five minutes, the access point is
Note
unable to find the Master Cisco wireless LAN controller. Check the connection between
the access point and the Cisco wireless LAN controller and be sure that they are on the
same subnet.
b. If the access point shuts down, check the power source.
c. After the access point finds the Cisco wireless LAN controller, it attempts to download the
new operating system code if the access point code version differs from the Cisco wireless
LAN controller code version. While this is happening, the Status LED blinks amber.
