Creating a Basic Configuration

To configure ATM, perform the following tasks. (Figure 3 shows the relationship of Steps 1 through 3.)

  1. Configure an ATM physical interface.
    host1(config)#interface atm 0/1
  2. Configure an ATM 1483 subinterface.
    host1(config-if)#interface atm 0/1.20
  3. Configure a PVC by specifying the VCD, the VPI, the VCI, and the encapsulation type.
    host1(config-subif)#atm pvc 10 15 22 aal5snap
  4. Assign an IP address and subnet mask to the PVC.
    host1(config-subif)#ip address 192.32.10.20 255.255.255.0
  5. (Optional) Verify your configuration using the appropriate show commands.
    host1#show atm interface atm 0/1 host1#show atm vc atm 0/1 10 host1#show atm subinterface atm 0/1.20
