Cisco Aironet 1840 Series Access Points
Note The maximum number of access points varies for the Cisco WiSM2, depending on which controller software
release is being used.
When the controller is maintaining join-related information for the maximum number of access points, it does not collect
information for any more access points.
An access point sends all syslog messages to IP address 255.255.255.255 by default when any of the following
conditions are met:
An access point running software release 8.2.110.0 or later has been newly deployed.
An existing access point running software release 8.2.110.0 or later has been reset after clearing the configuration.
If any of these conditions are met and the access point has not yet joined a controller, you can also configure a DHCP
server to return a syslog server IP address to the access point using option 7 on the server. The access point then starts
sending all syslog messages to this IP address.
When the access point joins a controller for the first time, the controller sends the global syslog server IP address (the
default is 255.255.255.255) to the access point. After that, the access point sends all syslog messages to this IP address
until it is overridden by one of the following scenarios:
The access point is still connected to the same controller, and the global syslog server IP address configuration on
the controller has been changed using the config ap syslog host global syslog_server_IP_address command. In
this case, the controller sends the new global syslog server IP address to the access point.
The access point is still connected to the same controller, and a specific syslog server IP address has been
configured for the access point on the controller using the config ap syslog host specific Cisco_AP
syslog_server_IP_address command. In this case, the controller sends the new specific syslog server IP address
to the access point.
The access point is disconnected from the controller and joins another controller. In this case, the new controller
sends its global syslog server IP address to the access point.
Whenever a new syslog server IP address overrides the existing syslog server IP address, the old address is erased
from persistent storage, and the new address is stored in its place. The access point also starts sending all syslog
messages to the new IP address provided the access point can reach the syslog server IP address.
You can configure the syslog server for access points and view the access point join information only from the controller
CLI.
Important Information for Controller-based Deployments
Keep these guidelines in mind when you use 1840 series access point:
The access point can only communicate with Cisco wireless controllers.
The access point does not support Wireless Domain Services (WDS) and cannot communicate with WDS devices.
However, the controller provides functionality equivalent to WDS when the access point joins it.
CAPWAP does not support Layer 2. The access point must get an IP address and discover the controller using Layer
3, DHCP, DNS, or IP subnet broadcast.
The access point console port is enabled for monitoring and debug purposes. All configuration commands are
disabled when the access point is connected to a controller.
