Configuring VDSL2 and ADSL2/2+ NIM for Cisco 4000 Series Integrated Service Routers
VDSL2 and ADSL2/2+ Cisco® 4000 Series Integrated Services Router Network Interface Modules (ISR NIMs) provide highly reliable WAN connections for remote sites. These interfaces offer cost-effective virtualized WAN connections in both point-to-point and point-to-multipoint designs. You can mix and match NIMs to tailor cost-effective solutions for common networking solutions for low- and high-density WAN aggregation.
Organization needs high speed digital data transmission to operate between their data equipment and central office, usually located at the telecom service provider premises. The Cisco multimode VDSL2 and ADSL1/2/2+ NIMs provide 1-port (2-pair) multimode VDSL2 and ADSl2+ WAN connectivity. This connectivity in combination with Cisco 4000 Series Integrated Service Routers, provides high-speed digital data transmission between customer premises equipment (CPE) and the central office.
This capability enables service providers and resellers to offer additional services, such as business-class security, voice, video, and data; differentiated classes of service (QoS), and managed network access over existing telephony infrastructure. These value-added features, along with the flexible manageability and reliability of Cisco IOS Software, provide the mission-critical networking features that businesses expect.
XDSL NIM Modules are supported from Cisco IOS XE Release 3.14.0S onwards on the Cisco® 4000 ISR series platforms.
For more information on DSLAM interoperability, refer to the Cisco Multimode VDSL2 and ADSL2/2 Network Interface Module Data Sheet.

DSL Feature Specifications
Configuring DSL
Cisco 4000 Series Integrated Services Routers (ISRs) support asymmetric digital subscriber line (ADSL) 1/2/2+ and very high speed digital subscriber line 2 (VDSL2) transmission modes, also called multimode.
Configuring ADSL
Perform the below mentioned steps to configure DSL controller.
Configuring Auto Mode
ProcedureConfiguring ADSL1 and ADSL2/2+ Annex A and Annex M Mode
ProcedureConfiguring VDSL2
A single-wire pair enables you to configure profile 8a through 17a on line 0, and profile 8a through 30a on line 1. Very-high-bit-rate digital subscriber line 2 (VDSL2) bonding combines two copper wire pairs to increase the capacity or extend the copper network's reach. For a customer, this means enhanced data rate and operation on longer loops.
Configuring a Single-Wire Pair on Line 0
ProcedureConfiguring a Single-Wire Pair on Line 1
ProcedureConfiguring Bonding in Auto Mode
ProcedureYou can configure bonding either in auto mode or VDSL2. The default configuration is auto.
Perform the following steps to configure bonding in auto mode:
Configuring Bonding in VDSL2 Mode
ProcedureDSL Interface Configuration Examples
In Cisco IOS XE, ATM PVCs can be configured under ATM sub-interfaces only. PVC configuration is not allowed under the main ATM interface. You can configure 8 point to point sub-interfaces either with one PVC configured under each point to point sub-interface or single multi-point sub-interface.
You do not need to configure the tx-ring-limit command in the Cisco® 4000 Series Integrated Services Routers, if you are migrating from classic Cisco IOS® and usingtx-ring-limit command to reduce the latency. Because the DSL NIM modules buffers have been fine tuned for the optimal performance and latency.
The following example shows how to configure ATM interface:
interface ATM0/1/0 no ip address no atm oversubscribe no atm enable-ilmi-trap no shutinterface ATM0/1/0.1 point-to-point ip address 71.71.71.1 255.255.255.0 no atm enable-ilmi-trap pvc 1/77 vbr-rt 400 400The following example shows how to configure Ethernet interface.
interface Ethernet0/1/0 ip address 75.75.75.1 255.255.255.0 load-interval 30 no negotiation auto
If the trained mode is VDSL2 or VDSL2+, the TC mode should be in Packet Transfer Mode (PTM). In this case, the PTM Ethernet interface is in the up state. All other upper layer parameters such as PPP, IP, and so on should be configured under the Ethernet interface. If the trained mode is ADSL, ADSL2, or ADSL2+, the TC mode should be ATM and all the upper layer parameters should be configured under the ATM Permanent Virtual Circuit (PVC). If you change the operating mode between ADSL and VDSL, you need not to reboot the router in order to activate the corresponding Ethernet or ATM interfaces. In case of PTM mode, check with your ISP if they are expecting Dot1q tag configuration on the CPE. ISP should provide Dot1q tag value.

ATM Conditional Debug Support
Most ATM debugging commands are implemented either at the system level or at the interface level. The ATM Conditional Debug Support feature allows debugging to be limited specifically to an ATM interface, to a virtual channel identifier (VCI), or to a virtual path identifier/virtual channel identifier (VPI/VCI) pair, through use of the debug condition interface command.
For more information on configuring ATM conditional debug support feature, see the ATM Conditional Debug Support document.
ATM OAM Loopback Mode Detection
The Loopback Mode Detection Through OAM feature allows you to enable automatic detection of when a peer ATM interface is in loopback mode. When loopback is detected on an interface where end-to-end F5 Operation, Administration, and Maintenance (OAM) is enabled, the impacted permanent virtual circuit (PVC) is moved to a DOWN state, and traffic is suspended. When the loopback condition in the peer ATM interface is removed, the PVC is moved back to an UP state.
For more information on configuring ATM OAM Loopback Mode Detection, see the Loopback Mode Detection through OAM document.
ATM Oversubscription for DSL
The ATM Oversubscription for DSL feature enables users to improve network utilization of otherwise underutilized shared networks by leveraging statistical multiplexing on ATM networks. Instead of supporting only unconditional reservation of network bandwidth to VBR PVCs, the Router offers PVC oversubscription to statistically guarantee bandwidth to VBR PVCs.
In Cisco IOS XE Release 3.14.0S or later, the ATM Oversubscription feature enables you to specify the amount of oversubscription (oversubscription factor) equal to twice the line rate. Following are the features of oversubscription:
Oversubscription is allowed on VBR-rt and VBR-nrt.
Under no over subscription condition, PVCs can be configured up to line rate. For example, if the line rate is 1000 Kbps. The SCR or PCR of a VBR PVC cannot be more than 1000 Kbps if there are no other PVCs. If there is a CBR PVC with PCR of 500Kbps, then the maximum SCR or PCR allowed on the VBR PVC is 500 Kbps.
When over-subscription is enabled, multiple VBR-rt or VBR-nrt PVCs are allowed to be configured even if the sum of their SCRs exceeds the actual bandwidth available over the physical line. Suppose oversubscription is enabled and over subscription factor of 2 is set for a line rate of 1000k sum of SCRs of VBR-rt and VBR-nrt can be less than or equal to 2000k, this is excluding CBR PVCs bandwidth.
If the user configures VBR-rt or VBR-nrt more than the configured oversubscription factor then PVC will be configured for the bandwidth available. If there is no oversubscription bandwidth left then VC will be downgraded to UBR. For example for line rate of 1000k, with oversubscription factor 2: PVC1 is vbr-rt 400k 400k, PVC2 is vbr-nrt 1600k 1600k and PVC3 is vbr-rt 500k 500k. In this case the PVC1 and PVC2 will be configured to given pcr and scr, PVC3 will be downgraded to UBR class.
If there is no bandwidth left, then some PVCs may be downgraded to UBR class.
PCR & SCR of VBR PVC can never exceed the line rate even if there is enough available bandwidth for the configured PCR and SCR.
Oversubscription of the ATM interfaces is enabled by default and is subject to infinite oversubscription factor which is not supported on DSL NIM. User must enable oversubscription factor.
The following configuration enables the oversubscription 2. The only oversubscription factor supported is 2.
Router(config)#interface atm 0/1/0 Router(config-if)#atm oversubscription factor 2 Router(config-if)#exitTo disable oversubscription of the interface, use the no atm oversubscribe command.
For example, the following configuration disables oversubscription of the ATM 0/1/0 interface:
Router(config)#interface atm 0/1/0 Router(config-if)#no atm oversubscribe Router(config-if)#exitExample:
Below is the example for the sum of pvc rates less than the line rate of 1561kbps.

ATM routed bridge encapsulation (RBE) is used to route IP over bridged RFC 1483 Ethernet traffic from a stub-bridged LAN.
For more information on configuring ATM RBE, see the Providing Connectivity Using ATM Routed Bridge Encapsulation over PVCs document.
Default Route on a PPP Virtual Access Interface
If a Virtual-Template (VT) interface is configured to obtain its IP address by IPCP, the dynamically created Virtual-Access (VA) interface gets the IP address after PPP negotiation. Since the Virtual-access is created dynamically, we cannot configure mappings on the dynamic interface. Also, there is no way to configure a static route through the virtual-access interface; we need to insert a default route via the next-hop address for the virtual-access and this is achieved using "ppp ipcp route default".
For more information on the usage of the command, see the ppp ipcp default route command document.
Dynamic Bandwidth Change for ATM PVCs
The ATM Dynamic Bandwidth for ATM PVCs over DSL feature provides the ability to configure Cisco IOS-XE software to automatically adjust PVC bandwidth in response to changes in the total available interface bandwidth. This feature eliminates the manual intervention every time DSL line rate changes, and allows the available bandwidth to be used effectively at all times.
It is recommended to enable ATM Dynamic Bandwidth feature on ATM interfaces. For more information on enabling the ATM Dynamic Bandwidth feature, refer the section "Enabling ATM Dynamic Bandwidth" .
Restrictions for Implementing ATM Dynamic Bandwidth
This feature is supported only for ATM permanent virtual circuits (PVCs).
The algorithm used to implement this feature is applied only when dynamic changes to ATM interface occur. It is applied at VC creation on Router bootup as well.
If the ATM Dynamic Bandwidth feature is enabled/disabled after a change in total bandwidth, feature would not work until line toggles.
Enabling ATM Dynamic Bandwidth
By default ATM dynamic bandwidth feature is enabled. If ATM dynamic bandwidth is disabled, perform the below steps to enable the feature:
Router#conf t Enter configuration commands, one per line. End with CNTL/Z. Router(config)#int atm0/1/0 Router(config-if)#atm bandwidth dynamic Router(config-if)#end Router#Sample configuration:
! interface ATM0/1/0 no ip address load-interval 30 no atm enable-ilmi-trap !Show atm pvc output with atm dynamic bandwidth enabled.

In example 2, CBR PVC was configured with PCR as 300 kbps. Due to line rate change, PCR rate has dynamically changed to 294 kbps.
Disabling ATM Dynamic Bandwidth
Router#conf t Enter configuration commands, one per line. End with CNTL/Z.

Router#show atm pvc | sec 0/1/0 0/1/0.1 1 8 37 PVC MUX UBR 1045 UP Router#How the ATM Dynamic Bandwidth Feature Works
When the total available bandwidth on a DSL interface changes, all of the PVCs configured under the ATM sub-interface(s) are re-created.
If necessary and applicable for a particular PVC based on its service class, new values are applied for the following parameters when PVCs are re-created:
The following steps are performed by the Cisco IOS-XE software to determine what value should be assigned to a parameter when a PVC is re-created in response to a change in total available bandwidth:
A value is calculated for the parameter. The calculation takes into account the configured value for the parameter, the active value for the parameter (if it is different from the configured value), and the change in total available bandwidth.
The calculated value is compared to the configured value of the parameter and to the maximum available cell rate, and a new value is determined. The new value is applied when the PVC is re-created.
The following sections describe how the new parameter values are determined when a PVC is re-created for supported QoS classes:
CBR PVCs
When the total available bandwidth changes, PVCs configured with CBR service class are recreated as follows:
If the configured PCR value is less than the calculated PCR value, the PVC is recreated with the configured PCR value.
If the configured PCR value is greater than the calculated PCR value, the PVC is recreated with the calculated value with no change in class.
If there is no bandwidth left for the CBR PVC, then CBR PVCs will be downgraded to UBR class with a PCR value equal to the maximum available rate.
VBR PVCs
When the total available bandwidth changes, PVCs configured with VBR service class are re-created as follows:
If the configured PCR value is less than the calculated PCR value, the PVC is recreated with the configured PCR value.
If the configured PCR value is greater than the calculated PCR value, the PVC is recreated with a new PCR value. The new PCR value will be the lower of the following values:
If the configured SCR value is less than the calculated PCR value, the PVC is re-created with the configured SCR value.
If the configured SCR value is greater than the calculated PCR value, the PVC is recreated with a new SCR value. The new SCR value will be the lower of the following values:
UBR PVCs
When the total available bandwidth changes, PVCs configured with UBR service class are re-created as follows:
If the PCR configuration is set to the default, the PVC is re-created with a PCR value equal to the new line rate.
If the configured PCR value is less than the calculated PCR value, the PVC is re-created with the configured PCR value.
If the configured PCR value is greater than the calculated PCR value, the PVC is recreated with a new PCR value. The new PCR value will be the lower of the following values:

Below is the example for the sum of pvc rates less than the line rate of 1561kbps.

IP to ATM CoS, Per-VC WFQ and CBWFQ QoS: PPPoE QoS Markings of .1P Bits in S (AOL)
IP to ATM CoS support for a single ATM VC allows network managers to use existing features, such as committed access rate (CAR) or policy-based routing (PBR), to classify and mark different IP traffic by modifying the IP Precedence field in the IP version 4 (IPv4) packet header. Subsequently, Weighted Random Early Detection (WRED) or distributed WRED (DWRED) can be configured on a per-VC basis so that the IP traffic is subject to different drop probabilities (and therefore priorities) as IP traffic coming into a router competes for bandwidth on a particular VC.
For more information, see the Configuring IP to ATM CoS document.
Low Latency Queueing
Low Latency Queuing (LLQ) allows delay-sensitive data such as voice to be dequeued and sent first (before packets in other queues are dequeued), giving delay-sensitive data preferential treatment over other traffic. The priority command is used to allow delay-sensitive data to be dequeued and sent first. LLQ enables use of a single priority queue within which individual classes of traffic can be placed. For more details on configuring LLQ, see the following documents:
Modular QoS CLI (MQC) Unconditional Packet Discard
The Modular QoS CLI (MQC) Unconditional Packet Discard feature allows customers to classify traffic matching certain criteria and then configure the system to unconditionally discard any packets matching that criteria. The Modular QoS CLI (MQC) Unconditional Packet Discard feature is configured using the Modular Quality of Service Command-Line Interface (MQC) feature. Packets are unconditionally discarded by using the new drop command within the MQC.
For more information on configuring Modular QOS CLI unconditional packet discard feature, see the Modular QoS CLI Unconditional Packet Discard document.
MQC Policy Map Support on Configured VC Range ATM
The Modular Quality of Service Command Line Interface (MQC) Policy Map support on Configured VC Range ATM feature extends the functionality for policy maps on a single ATM VC to the ATM VC range.
For more information on configuring MQC Policy Map Support on Configured VC Range ATM, see the MQC Policy Map on Configured VC Range ATM document.
Multilink PPP (MLPPP) bundling
This feature describes how to configure Multilink PPP over broadband interfaces. Configuring Multilink PPP over broadband includes configuring Multilink PPP over ATM (MLPoA), Multilink PPP over Ethernet (MLPoE), Multilink PPP over Ethernet over ATM (MLPoEoA), and so on.
For more information on Multilink PPP bundles and to configure Multilink PPP minimum links, Bundling and Multilink PPP support on multiple VC's , see the following documents:
Configuring Multilink PPP Connections for Broadband and Serial Topologies
PPPoE Enhancement with RFC 4638
The PPP over Ethernet Client feature provides PPP over Ethernet (PPPoE) client support on routers on customer premises.
For more information on configuring PPP over Ethernet feature, see the PPP over Ethernet Client document.
PPPoEoA over ATM AAL5Mux
The PPPoEoA over ATM AAL5MUX feature enables PPP over Ethernet (PPPoE) over ATM adaptation layer 5 (AAL5)-multiplexed permanent virtual circuits (PVCs), reducing logical link control (LLC) and Subnetwork Access Protocol (SNAP) encapsulation bandwidth usage and thereby improving bandwidth usage for the PVC.
For more information on configuring PPPoEoA over ATm AAL5MUX feature, see How to Configure PPPoEoA over ATM AAL5MUX at PPPoEoA over ATM AAL5Mux.
PPP Over ATM (IETF-Compliant)
PPP over ATM enables a high-capacity central site router with an ATM interface to terminate multiple remote PPP connections. PPP over ATM provides security validation per user, IP address pooling, and service selection capability.
For more information on configuring PPP over ATM for different encapsulation types, see the following documents:
Providing Protocol Support for Broadband Access Aggregation of PPP over ATM Sessions
PPPoE Specification Conformance with PADT Message
The PPP over Ethernet Client feature provides PPP over Ethernet (PPPoE) client support on routers on customer premises.
For more information on configuring PPP over Ethernet feature, see the PPP over Ethernet Client document.
QoS on Dialer
QOS on dialer interfaces feature provides support for Point-to-Point Protocol over Ethernet (PPPoE) and Point-to-Point Protocol over Asynchronous Transfer Mode (PPPoA) configurations on dialer interfaces. The feature provides support for Modular QoS CLI (MQC)-based queuing and shaping that supports per-customer quality of service (QoS). For more details on configuring QOS on dialer, see the Shaping on Dialer Interfaces document.
QoS: PPPoE QoS Markings of .1P Bits
The 802.1P CoS Bit Set for PPP and PPPoE Control Frames feature provides the ability to set user priority bits in the IEEE 802.1Q tagged frame to allow traffic prioritization. This capability enables a way to provide best effort quality of service (QoS) or class of service (CoS) at layer 2 without requiring reservation setup.
For more information on configuring PPPoE QOS Markings of 802.1P bits feature, see the 802.1P CoS Bit Set for PPP and PPPoE Control Frames document.
RBE Client Side Encapsulation with QoS
The RBE client side encapsulation with QoS feature provides secure connectivity to an ATM bridged network in which previously a broadband access server would not forward Address Resolution Protocol (ARP) requests or perform proxy ARP, and would respond to ARPs for its own IP address only. This feature combines RBE with QoS policy-based routing to provide security to the entire network. RBE was developed to address known issues with RFC1483 bridging such as broadcast storms and security.
For more information on configuring ATM RBE with QOS, see the following documents:
RBE Client Side Encapsulation with QoS and the Command References
VC Bundling
APP License is required to support this feature on this module in Cisco IOS XE.
Router(config)#license boot level appxk9
ATM VC bundle management allows you to define an ATM VC bundle and add VCs to it. You can configure multiple Permanent Virtual Circuits (PVC) that have different QoS characteristics between two end devices. Each VC of a bundle has its own ATM traffic class and ATM traffic parameters. You can apply attributes and characteristics to discrete VC bundle members, or you can apply them collectively at the bundle level.
For more details on configuring VC Bundling, see the Configuring ATM document.
