Adding an ATM-over-ADSL Network Interface with a Configuration Editor

Navigate to the Interfaces level in the configuration hierarchy.

1. In the configuration editor hierarchy, select Configuration>View and Edit>Edit Configuration.
2. Next to Interfaces, click Edit.

From the top of the configuration hierarchy, create and name the interface:

edit interfaces at-2/0/0

Create the new interface—for example, at-2/0/0.

1. Next to Interface, click Add new entry.
2. In the Interface name box, type at-2/0/0.
3. Click OK.

Configure ATM virtual path identifier (VPI) options for the interface.

• ATM VPI—A number between 0 and 255—for example, 25.
• Operation, Maintenance, and Administration (OAM) F5 loopback cell thresholds on ATM virtual circuits. The range is between 1 and 255, and the default is 5 cells.
  • Down count—Number of consecutive OAM loopback cells an ATM virtual circuit must lose to be identified as unavailable—for example, 200.
  • Up count—Number of consecutive OAM loopback cells an ATM virtual interface must receive to be identified as operational—for example, 200.
• OAM period—Interval, in seconds, at which OAM cells are transmitted on ATM virtual circuits—for example, 100. The range is between 1 and 900 seconds.

1. Next to Atm options, click Configure.
2. Next to Vpi, click Add new entry.
3. In the Vpi number box, type 25.
4. In the Actions box, click Edit.
5. Next to Oam liveness, click Configure.
6. In the Down count box, type 200.
7. In the Up count box, type 200.
8. Click OK.
9. Next to Oam period box, click Configure.
10. From the Oam period choices list, select Oam period.
11. In the Oam period box, type 100.
12. Click OK.

1. To configure the VPI value, enter

   set atm-options vpi 25

2. To configure OAM liveness values on a VPI, enter

   set atm-options vpi 25 oam-liveness up-count 200 down-count 200

3. To configure the OAM period, enter

   set atm-options vpi 25 oam-period 100

Configure the type of DSL operating mode for the ATM-over-ADSL interface—for example auto.

Annex A and Annex B support the following operating modes:

Annex A supports the following operating modes:

Annex B supports the following operating modes:

• auto—Configures the ADSL interface to autonegotiate settings with the DSLAM located at the central office. For Annex A, the ADSL interface trains in either ANSI T1.413 Issue II mode or ITU G.992.1 mode. For Annex B, the ADSL interface trains in ITU G.992.1 mode.
• itu-dmt—Configures the ADSL interface to train in ITU G.992.1 mode.

• adsl2plus—Configures the ADSL interface to train in ITU G.992.5 mode. You can configure this mode only when it is supported on the DSLAM.
• itu-dmt-bis—Configures the ADSL interface to train in ITU G.992.3 mode. You can configure this mode only when it is supported on the DSLAM.

• ansi-dmt—Configures the ADSL interface to train in the ANSI T1.413 Issue II mode.
• etsi—Configures the ADSL line to train in the ETSI TS 101 388 V1.3.1 mode.
• itu-annexb-ur2—Configures the ADSL line to train in the G.992.1 Deutsche Telekom UR-2 mode.
• itu-annexb-non-ur2—Configures the ADSL line to train in the G.992.1 Non-UR-2 mode.

1. Next to Dsl options, click Configure.
2. From the Operating Mode list, select auto.
3. Click OK.

Enter

set dsl-options operating-mode auto

Configure the encapsulation type—for example, ethernet-over-atm.

• atm-pvc—ATM permanent virtual circuits is the default encapsulation for ATM-over-ADSL interfaces.

  For PPP over ATM (PPPoA) over ADSL interfaces, use this type of encapsulation.

• ethernet-over-atm—Ethernet over ATM encapsulation.

  For PPP over Ethernet (PPPoE) over ATM-over-ADSL interfaces that carry IPv4 traffic, use this type of encapsulation.

1. From the Encapsulation list, select ethernet-over-atm.
2. Click OK.

Enter

set encapsulation ethernet-over-atm

Add the logical interface.

Set a value from 0 and 16385—for example, 3.

Add other values if required by your network.

1. Scroll down the page to Unit, and click Add new entry.
2. In the Interface unit number box, type 3..
3. Enter other values in the fields required by your network.

Enter

set unit 3

Configure encapsulation for the ATM-for-ADSL logical unit—for example, atm-nlpid.

The following encapsulations are supported on the ATM-over-ADSL interfaces that use inet (IP) protocols only:

• atm-vc-mux–Use ATM virtual circuit multiplex encapsulation.
• atm-nlpid–Use ATM network layer protocol identifier (NLPID) encapsulation.
• atm-cisco-nlpid–Use Cisco NLPID encapsulation.
• ether-over-atm-llc–For interfaces that carry IPv4 traffic, use Ethernet over LLC encapsulation. You cannot configure multipoint interfaces if you use this type of encapsulation.

The following encapsulations are supported on the ATM-over-ADSL for PPP-over-ATM (PPPoA) interfaces only. (For a sample PPPoA configuration, see Verifying Interface Configuration.)

• atm-ppp-llc– AAL5 logical link control (LLC) encapsulation.
• atm-ppp-vc-mux—Use AAL5 multiplex encapsulation.

Other encapsulation types supported on the ATM-over-ADSL interfaces:

• ppp-over-ether-over-atm-llc–Use PPP over Ethernet over ATM LLC encapsulation. When you use this encapsulation type, you cannot configure the interface address. Instead you configure the interface address on the PPP interface.
• atm-mlppp-llc–Use ATM Multilink PPP over AAL5 LLC encapsulation.
• atm-snap–Use ATM subnetwork attachment point (SNAP) encapsulation.

From the Encapsulation list, select atm-nlpid.

Enter

set unit 3 encapsulation atm-nlpid

Add the Family protocol type—for example, inet.

Select the protocol type inet and then click Configure.

Enter

set unit 3 family inet

Commands vary depending on the protocol type.

Configure ATM virtual channel identifier (VCI) options for the interface.

• ATM VCI type—vci.
• ATM VCI value—A number between 0 and 4089—for example, 35, with VCI's 0 through 31 reserved.
• Operation, Maintenance, and Administration (OAM) F5 loopback cell thresholds on ATM virtual circuits. The range is between 1 and 255, and the default is 5 cells.
  • Down count—Number of consecutive OAM loopback cells an ATM virtual circuit must lose to be identified as unavailable—for example, 200.
  • Up count—Number of consecutive OAM loopback cells an ATM virtual interface must receive to be identified as operational—for example, 200.
• OAM period—Interval, in seconds, at which OAM cells are transmitted on ATM virtual circuits—for example, 100. The range is between 1 and 900 seconds.
