Access point overview

The Cisco 819 ISR supports built-in enterprise class WLAN capability with an embedded Cisco 3500 Access Point featuring 802.11a/b/g/n and 2X3 MIMO antenna diversity (2 transmitting antennas and 3 receiving antennas).  With the dual 802.11 radio capability, the integrated AP can serve both as an access point and as a client to another wireless network for backbone/internet connectivity. This provides another source for WAN diversity along with Gigabit Ethernet, serial, and 3G/4G capabilities.

The Cisco 819 ISR router wireless access-point is a service module connected to the router with the following interfaces :

  • wlan-ap0 for access point management
  • Wlan-GigabitEthernet0 for production traffic between the router and the AP. This interface can be configured as a trunk to allow the AP to link multiple SSID to different vlans

Access Point connection

The Cisco 819 embedded access point is not configured through the router's running-config. After setting up an IP address to the wlan-ap0 router interface, connect to the access point using the following command in privileged mode :

Router# service-module wlan-ap0 session

Detailled configuration :

Router(config)# interface wlan-ap0
Router(config-if)# ip address 10.10.10.1 255.255.255.0
Router(config-if)# no shut
Router(config-if)# exit

Router# service-module wlan-ap0 session
Trying 10.10.10.1, 2002 ... Open

Guest SSID configuration

The following configuration steps are required to configure a working guest SSID

  • Define the SSID name (dot11 ssid SSID_NAME)
  • Configure the SSID in guest mode (guest-mode)
  • Configure the SSID authentication method (auhentication open / open eap / network-eap )
  • Link the configured ssid to a Dot11Radio interface
