Chapter 2 Configuring Radio Settings
Configuring Universal Client Mode
c2801(config-if)#station-role ?
non-root Non-root (bridge)
root Root access point or bridge
c2801(config-if)#station-role non-root ?
bridge Bridge non-rootThis CLI enables non-root bridge mode.
<cr> This CLI enables universal client mode
DHCP
IP DHCP addressing is supported in the Dot11Radio interface configured in universal client mode. The
following is an example of Dot11Radio configured with "ip address dhcp":
dot11 ssid test10
authentication open
!
interface Dot11Radio0/1/0
ip address dhcp
!
ssid test10
!
speed basic-1.0 basic-2.0 basic-5.5 6.0 9.0 basic-11.0 12.0 18.0 24.0 36.0 48.0 54.0
station-role non-root
Issuing a "show ip interface brief" will show the Virtual-Dot11Radio interface getting the IP address
from the DHCP server.
c2801_uc#sh ip int brief

Dot11Radio0/1/1 unassigned YES NVRAM administratively down down
Virtual-Dot11Radio0 200.1.1.2 YES DHCP up up

NAT (Network Address Translation):
NAT translation takes place if you overload the interface which has an ip address. In the case of universal
client, the virtual-interface has the ip address obtained from the DHCP. Hence we require to overload the
virtual interface to aid NAT translation.
Note NAT fails to translate with a DHCP address on the dot11 interface running in universal client mode.
The following configuration is supported on NAT:
ip nat inside source list 1 interface Virtual-Dot11Radio0 overload
The following is an example of a NAT configuration on a Cisco 1803 ISR:
C1803W_UC#
C1803W_UC#sh run
