Additional Configuration Tasks

Class B network is 172.16.0.0, 8subnet bits; mask is

255.255.255.0

Step 2 Repeat Step 1 for each BRI interface installed in your router.

Conﬁguring the ATM Network Processor Module Interface

If you installed a new ATM network processor module or if you want to change the

conﬁguration of an existing module, you must enter the conﬁguration mode. If you replaced

an ATM network processor module that was previously conﬁgured, the system will

recognize the new module and bring it up in the existing conﬁguration.

When you have veriﬁed that the new ATM network processor module is recognized by the

router, use the privileged-level conﬁgure command to conﬁgure the new module. You

should have available the following information:

• ATM transceiver framing type (STS-3c, STM-1, DS-3, or E3)

• Network protocol addresses

• Permanent virtual circuit (PVC) connections and their attributes

• Static address mappings (address lists)

The following steps describe a basic ATM conﬁguration using just PVCs. 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 int atm command 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.
