Chapter 6 Configuring Radio Settings
Configuring the Role in Radio Network
You can also configure a fallback role for root access points. The wireless device automatically assumes
the fallback role when its Ethernet port is disabled or disconnected from the wired LAN. There are two
possible fallback roles:
•
Repeater
—When the Ethernet port is disabled, the wireless device becomes a repeater and
associates to a nearby root access point. You do not have to specify a root access point to which the
fallback repeater associates; the repeater automatically associates to the root access point that
provides the best radio connectivity.
•
Shutdown
—the wireless device shuts down its radio and disassociates all client devices.
Beginning in privileged EXEC mode, follow these steps to set the wireless device’s radio network role
and fallback role:

When configuring a universal workgroup bridge using AES-CCM TKIP, the non-root device should use only TKIP or
AES-CCM TKIP as ciphers in order to associate to the root device. The non-root device will not associate with the root if it
is configured only AES-CCM. This configuration results in a mismatch in the multicast cipher between the root and non-root
devices.
