Logical Interfaces
|
Lists the logical interfaces for this ATM-over-ADSL physical
interface.
|
- To add a logical interface, click Add.
- To edit a logical interface, select the interface from
the list.
- To delete a logical interface, select the check box next
to the name and click Delete.

or Editing a Logical Interface |
|
Add logical interfaces
|
Defines one or more logical units that you connect to this physical
ADSL interface.
|
Click Add.
|
|
Logical Interface Description
|
(Optional) Describes the logical interface.
|
Type a text description of the logical interface to more clearly
identify it in monitoring displays.
|
|
Encapsulation
|
Specifies the type of encapsulation on the DSL logical interface.
|
From the list, select one of the following types of encapsulations.
For ATM-over-ADSL interfaces that use inet (IPv4) protocols
only, select one of the following:
-
ATM VC multiplexing—Use ATM virtual circuit
multiplex encapsulation.
-
ATM NLPID—Use ATM network layer protocol
identifier (NLPID) encapsulation.
-
Cisco-compatible ATM NLPID—Use Cisco NLPID
encapsulation.
-
Ethernet over ATM (LLC/SNAP)—For interfaces
that carry IPv4 traffic, use Ethernet over logical link control (LLC)
encapsulation. You cannot configure multipoint interfaces if you use
this type of encapsulation.
For ATM-over-ADSL for PPP-over-ATM (PPPoA) interfaces only,
select one of the following:
-
ATM PPP over AAL5/LLC—Use
AAL5 logical link control (LLC) encapsulation.
-
ATM PPP over Raw AAL5—Use AAL5 multiplex
encapsulation.
For other encapsulation types on the ATM-over-ADSL interfaces,
select one of the following:
-
PPPoE over ATM (LLC/SNAP)—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.
-
Ethernet over ATM (LLC/SNAP)—Use ATM subnetwork
attachment point (SNAP) encapsulation.
|
|
VCI
|
Configures the ATM virtual circuit identifier (VCI) for the
interface.
|
In the VCI box, type the number for the VCI.
|
|
Add IPv4 address prefixes and destinations
|
Specifies one or more IPv4 addresses and destination addresses.
|
Click Add.
|
|
IPv4 Address Prefix
|
Specifies an IPv4 address for the interface.
|
Type an IPv4 address and prefix. For example:
10.10.10.10/24
|
|
Destination Address
|
Specifies the destination address.
|
- Type an IPv4 address for the destination.
- Click OK.

Physical Interface Properties |
|
Physical Interface Description
|
(Optional) Adds supplementary information about the physical
ATM-over-ADSL interface.
|
Type a text description of the physical ATM-over-ADSL interface
to more clearly identify it in monitoring displays. Specify that it
is an ADSL interface.
|
|
MTU (bytes)
|
Specifies the maximum transmit size of a packet for the ATM-over-ADSL
interface.
|
Type a value from 256 to 9150.
|
|
Encapsulation
|
Selects the type of encapsulation for traffic on this physical
interface.
|
From the list, select the type of encapsulation for this ATM-over-ADSL
interface:
-
ATM permanent virtual circuits—Use this
type of encapsulation for PPP over ATM (PPPoA) over ADSL interfaces.
This is the default encapsulation for ATM-over-ADSL interfaces.
-
Ethernet over ATM encapsulation—Use this
type of encapsulation for PPP over Ethernet (PPPoE) over ATM-over-ADSL
interfaces that carry IPv4 traffic.
|
|
VPI
|
Configures the ATM virtual path identifier for the interface.
|
Type a VPI value between 0 and 255.
|
| Configuring
ADSL Options |
|
Operating Mode
|
Specifies the type of DSL operating mode for the ATM-over-ADSL
interface.
|
From the list, select one of the following types of DSL operating
modes—for example auto.
For Annex A or Annex B, select one of the following:
For Annex A only, select one of the following:
For Annex B only, select one of the following:
-
auto—Configure 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—Configure the ADSL
interface to train in ITU G.992.1 mode.
-
adsl2plus—Configure 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—Configure 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—Configure
the ADSL interface to train in the ANSI T1.413 Issue II mode.
-
etsi—Configure
the ADSL line to train in the ETSI TS 101 388 V1.3.1 mode.
-
itu-annexb-ur2—Configure the ADSL line to train in the
G.992.1 Deutsche Telekom UR-2 mode.
-
itu-annexb-non-ur2—Configure the ADSL line to train in
the G.992.1 Non-UR-2 mode.
