Chapter 7 Configuring Radio Settings
Configuring Radio Data Rates
See
Chapter 18, “Configuring Repeater and Standby Access Points,”
for detailed instructions on setting
up repeaters.
You can also configure a fallback role for the access point radio. The access point 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 access point becomes a repeater and associates
to a nearby root access point.
•
Shutdown—The access point shuts down its radio and disassociates all client devices.
Beginning in privileged EXEC mode, follow these steps to set the access point’s radio network role and
fallback role:
Configuring Radio Data Rates
You use the data rate settings to choose the data rates the access point uses for data transmission. The
rates are expressed in megabits per second. The access point always attempts to transmit at the highest
data rate set to
Basic
, also called
Require
on the browser-based interface. If there are obstacles or
interference, the access point steps down to the highest rate that allows data transmission. You can set
each data rate (1, 2, 5.5, and 11 megabits per second) to one of three states:
•
Basic (this is the default state for all data rates)—Allows transmission at this rate for all packets,
both unicast and multicast. At least one of the access point's data rates must be set to Basic.
•
Enabled—The access point transmits only unicast packets at this rate; multicast packets are sent at
one of the data rates set to Basic.
•
Disabled—The access point does not transmit data at this rate.
Note
At least one data rate must be set to
basic
.
You can use the Data Rate settings to set up an access point to serve client devices operating at specific
data rates. For example, to set up the access point for 11 megabits per second (Mbps) service only, set
the 11-Mbps rate to
Basic
and set the other data rates to
Enabled
. To set up the access point to serve
only client devices operating at 1 and 2 Mbps, set 1 and 2 to
Basic
and set the rest of the data rates to
Enabled
.

Set the access point role.
•
Set the role to repeater or root.
•
(Optional) Select the radio’s fallback role. If the access
point’s Ethernet port is disabled or disconnected from the
wired LAN, the access point can either shut down its radio
port or become a repeater access point associated to a
nearby root access point.
