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.

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.
|
|
IPv4 Addresses and Prefixes
|
Specifies one or more IPv4 addresses for the interface.
|
- Type one or more IPv4 addresses and prefixes. For example:
10.10.10.10/24
- Click Add.
- Click OK.
|
|
Destination Address
|
Specifies the destination address.
|
Type an IPv4 address for the destination.
|
|
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.

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 9192.
|
|
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.
