Configuration Tasks

	Command	Purpose
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.
Step 11
	Router(config-if)# shut	Stops the interface.
Step 12
	Router(config-if)# no loopback	Removes any loopback commands used up to this
		point.
Step 13
	Router(config-if)# no shut	Establishes link.

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.

	Command	Purpose
Step 1
	Router# show radio capability modulation-profile int	Displays the modulation profiles supported by the
	radio slot/port	radio card installed in a particular slot/port.
Step 2
	Router# configure terminal	Enables the global interface configuration mode.
Step 3
	Router(config)# radio modulation-profile p bandwidth	Creates a modulation profile.
	width throughput x.y mulipath-robust high burst-length
	medium
Step 4
	Router(config)# end	Exits the interface configuration mode and enters
		the EXEC mode.
Step 5
	Router# show radio modulation-profile	Displays the modulation-profile configuration
		settings that the user specified.
Step 6
	Router# configure terminal	Enables the global interface configuration mode.
Step 7
	Router(config)# interface radio slot/port	Enters radio interface configuration mode.
Step 8
	Router(config-if)#radio upstream usport subchannel sn	Applies the modulation profile to an upstream
	modulation-profile p	port.
