Chapter Configuring Radio Settings
Configuring the Role in the Radio Network
DETAILED STEPS
Note When you enable the role of a device in the radio network as a bridge/workgroup bridge and enable the
interface using the no shut command, the physical status and the software status of the interface will be
up (ready) only if the device on the other end (access point or bridge) is up. Otherwise, only the physical
status of the device will be up. The software status will be up when the device on the other end is
configured and ready.
Command Purpose
Step 1
configure terminal Enters global configuration mode.
Step 2
interface dot11radio {0| 1} Enters interface configuration mode for the radio interface.
The 2.4-GHz and 802.11g/n 2.4-GHz radios are radio 0.
The 5-GHz and the 802.11n 5-GHz radio is radio 1.
Step 3
station-role
non-root {bridge | wireless-clients}
root {access-point | ap-only |
[bridge | wireless-clients] |
[fallback | repeater | shutdown]}
workgroup-bridge {multicast |
mode <client | infrastructure>|
universal <Ethernet client MAC
address>}
Sets the wireless device role.
• Set the role to non-root bridge with or without wireless
clients, to root access point or bridge, or to workgroup
bridge.
Note The bridge mode radio supports point-to-point
configuration only.
Note The repeater and wireless-clients commands are not
supported on Cisco 1941-W Integrated Services
Routers.
Note The scanner command is not supported on 1941-W
Integrated Services Routers.
• The Ethernet port is shut down when any one of the radios
is configured as a repeater. Only one radio per access point
may be configured as a workgroup bridge or repeater. A
workgroup bridge can have a maximum of 25 clients,
presuming that no other wireless clients are associated to
the root bridge or access point.
Step 4
end Returns to privileged EXEC mode.
Step 5
copy running-config startup-config (Optional) Saves your entries in the configuration file.
