Additional Configuration Tasks

Step 8 Create the mapping of protocol addresses to PVCs. Map lists are used to assign

protocol addresses to virtual circuits (VCs):

Router(config-if)# map-list list1

Router(config-map-list)# ip 1.1.1.2 atm-vc 1 broadcast

Router(config-map-list)# ip 1.1.1.3 atm-vc 2 broadcast

Step 9 Press Ctrl-Z to complete the conﬁguration.

Step 10 Write the new conﬁguration to memory:

Router# write memory

Step 11 Exit the privileged level and return to the user level:

Router# disable

The following example shows a basic conﬁguration using switched virtual circuits (SVCs).

Press Return after each step.

Step 1 At the privileged-level prompt (Router #), enter conﬁguration mode and specify

that the console terminal will be the source of the conﬁguration commands:

Router# conf t

Step 2 Specify the unit to conﬁgure by entering the command int atm and the unit

number of the network processor module you are conﬁguring. For more

information on unit numbers, refer to the section “Unit Numbering” in the

chapter “Making External Connections to the Cisco 4000 Series.” The following

example is for an ATM module with unit number 0:

Router(config)# int atm 0

Step 3 Specify the framing type.

If you are using a SONET interface, there is only one framing type, STM-1,

which is the default and need not be entered:

Router(config-if)# atm sonet stm-1

If you are specifying the framing type for an E3 interface, there are two framing

types: G.751 ADM (entered as g751adm) and G.832 ADM (entered as

g832adm).
