Cisco Cisco Aironet 1810w Access Point Guía De Instalación

An existing access point running software release 8.2.x.x 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.

Keep these guidelines in mind when you use 1810W series access points:

The access point can only communicate with Cisco wireless LAN 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.
