Command:

map-class dialer


Mode:

Router(config)#

Syntax:

map-class dialer classname

Syntax Description:

classname

Unique class identifier.


Command Description:

To define a class of shared configuration parameters for outgoing calls from an ISDN interface, use the map-class dialer global configuration command. 

This command first appeared in Cisco IOS Release 11.0.

The classname in the map-class dialer command used to specify the class must be the same as a classname used in a dialer map command.

This command is used to define classes of calls for PPP callback for DDR, for ISDN Advice of Charge, and for Network Specific Facilities (NSF) call-by-call dialing plans.

For NSF call-by-call support on ISDN Primary-4ESS switches only, use one of the dialing-plan keywords listed in the table below.

Example:

 

The following example configures the PPP callback server on an ISDN BRI interface on a router in Atlanta. The callback server requires an enable timeout and a map class to be defined.

Router(config)#interface BRI0
Router(config-if)#ip address 7.1.1.7 255.255.255.0
Router(config-if)#encapsulation ppp
Router(config-if)#dialer callback-secure
Router(config-if)#dialer enable-timeout 2
Router(config-if)#dialer map ip 7.1.1.8 name atlanta class dial1 81012345678901
Router(config-if)#dialer-group 1
Router(config-if)#ppp callback accept
Router(config-if)#ppp authentication chap
Router(config)#map-class dialer dial1 
Router(config-map-class)#dialer callback-server  username


The following example configures the ISDN switch type to Primary-4ESS and configures ISDN PRI on T1 controller 1/0, and sets the D channel for dialer map classes that reference the NSF dialing plans. Finally, the map-class dialer command uses a dialing plan keyword and the dialer outgoing command refers to the same plan.

Router(config)#isdn switch-type primary-4ess
Router(config)#controller T1  1/0
Router(config-controller)#framing esf
Router(config-controller)#linecode b8zs
Router(config-controller)#pri-group timeslots 1-24
Router(config)#interface Serial 1/0:23
Router(config-if)#description
  This is the DMS D-channel 415-390-9503
Router(config-if)#ip address 6.1.1.3 255.255.255.0
Router(config-if)#encapsulation ppp
Router(config-if)#no keepalive
Router(config-if)#dialer map ip 6.1.1.1 name tommyjohn class sdnplan 14085770715
Router(config-if)#dialer map ip 6.1.1.2 name angus class megaplan 14085773775 
Router(config-if)#dialer map ip 6.1.1.4 name angus class accuplan 14085773778 
Router(config-if)#dialer-group 1
Router(config-if)#ppp authentication chap
Router(config)#map-class dialer sdnplan
Router(config-map-class)#dialer outgoing sdn
Router(config)#map-class dialer megaplan
Router(config-map-class)#dialer voice-call
Router(config-map-class)#dialer outgoing megacomm
Router(config)#map-class dialer accuplan
Router(config-map-class)#dialer outgoing accunet
  


The following example configures a map class called "hawaii" and sets an ISDN speed of 56 kbps for the class.

 

Router(config)#map-class dialer hawaii
Router(config-map-class)#isdn speed 56
 

 

The following example configures BRI 0 to function as the callback server on the shared network. The callback server requires an enable timeout and a map class to be defined.

Router(config)#interface bri 0
Router(config-if)#ip address 10.2.1.7 255.255.255.0
Router(config-if)#encapsulation ppp
Router(config-if)#dialer callback-secure
Router(config-if)#dialer enable-timeout 2
Router(config-if)#dialer map ip  10.2.1.8 name atlanta class dial1 81012345678901
Router(config-if)#dialer-group 1
Router(config-if)#ppp callback accept
Router(config-if)#ppp authentication chap
Router(config)#map-class dialer dial1
Router(config-map-class)#dialer callback-server username
