Issue the show running-configuration command to see the RF configuration.
Configuring the Modulation Profile for a Wireless Link
The modulation profile describes the physical layer configuration of a wireless channel. The correct settings
to use are the result of extensive site planning and quality-of-service models. The specified settings are
stored in the router as profiles. These profile settings are entered in the router only once, but can be applied
to multiple line cards in the router.
Step 8
Router(config-if)# loopback local rf diversity 2
Configures the RF to loop the lower half of the
channel for antenna 2. Note that this command is
issued only if a second antenna is used.
Step 9
Router(config-if)# loopback local rf diversity 3
Configures the RF to loop the upper half of the
channel for antenna 2. Note that this command is
issued only if a second antenna is used.
Step 10
Router(config-if)# no shut
Brings up in loopback mode.

Removes any loopback commands used up to this
point.
Step 13
Router(config-if)# no shut
Establishes link.
