New Hardware Features in Cisco IOS Release 12.0(33)S3

There are no new hardware features in Cisco IOS Release 12.0(33)S3.

New Software Features in Cisco IOS 12.0(33)S3

This section describes new and changed features in Cisco IOS Release 12.0(33)S3. Some features may be new to Cisco IOS Release 12.0S but were released in earlier Cisco IOS software releases. Some features may have been released in earlier Cisco IOS software releases and have been changed in Cisco IOS Release 12.0(33)S3. To determine if a feature is new or changed, see the feature history table at the beginning of the feature module for that feature.

BGP Support for 4-Byte ASN

Platform: Cisco 12000-GRP, Cisco 12000-PRP

The BGP Support for 4-Byte ASN feature was introduced in Cisco IOS Release 12.0(32)S12 with asdot format support only for 4-byte autonomous system numbers. In Cisco IOS Release 12.0(33)S3, support for the asplain format of 4-byte autonomous system numbers is introduced. Both asplain and asdot format are now supported, but the default format has changed to the asplain format.

For detailed information about this feature, see the "Cisco BGP Overview" and "Configuring a Basic BGP Network" modules of the Cisco IOS IP Routing Protocols Configuration Guide and the Cisco IOS IP Routing Protocols Command Reference at the following URLs:

New Hardware Features in Cisco IOS Release 12.0(33)S2

There are no new hardware features in Cisco IOS Release 12.0(33)S2.

New Software Features in Cisco IOS 12.0(33)S2

This section describes new and changed features in Cisco IOS Release 12.0(33)S2. Some features may be new to Cisco IOS Release 12.0S but were released in earlier Cisco IOS software releases. Some features may have been released in earlier Cisco IOS software releases and have been changed in Cisco IOS Release 12.0(33)S2. To determine if a feature is new or changed, see the feature history table at the beginning of the feature module for that feature.

Flow-control CLI

Flow control functionality is particularly useful when a remote end does not support flow control and a need arises to disable flow control on a Gigabit Ethernet (GE) or Fast Ethernet (FE) interface on a Cisco 12000 series router. By default, flow control is enabled on a GE or FE interface. Use the show interface flowcontrol command to view the flow control configuration on interfaces. To enable flow control, use the flowcontrol bidirectional command; to disable flow control, use the no flowcontrol bidirectional command. The flow control configuration must be same on both ends of the link (both enabled or both disabled).

Prerequisites to Execute Flow Control CLIs

1) Commands supported on Cisco IOS Release 12.0(33)S2.

2) Supported on Cisco 12000 series routers.

3) Supported only on GE or FE interfaces of an Engine 5 SIP-401/501/600/601 line card.

4) Disable auto-negotiation using the no negotiation auto command before executing the [no] flowcontrol bidirectional command.

Caveats of Flow Control Functionality

1) Not supported on a GE SPA interface with a Copper SFP inserted in it.

2) Not supported on a 1-Port 10-Gigabit Ethernet SPA.

3) Not supported on the SPA-2X1GE-V2.

For more information, see the "SIP and SPA Commands" chapter of the Cisco 12000 Series Router SIP and SPA Software Configuration Guide, 12.0(33)S:

IPHC Over Frame Relay for Interface Support

IP header compression is a mechanism that compresses the IP header in a packet before the packet is transmitted. Header compression reduces network overhead and speeds up the transmission of either Real-Time Transport Protocol (RTP) or Transmission Control Protocol (TCP) packets.

The IPHC Over Frame Relay for Interface Support feature enables efficient transmission of real-time traffic such as voice and video by compressing and decompressing the packet header. IPHC over Frame Relay is supported on Cisco 12000 Series Engine 5 based SIP-401/501/601 line cards on Frame Relay interfaces. For Frame Relay, the Cisco encapsulation type is the only encapsulation type on which this feature is supported. This feature is already supported on PPP/MLPPP interfaces. This feature has been designed for slow links so that optimum usage of bandwidth can be obtained and so that the quality of delay-sensitive traffic such as voice and video is not affected. IPHC works by first sending a full-header, and as the difference in packet remains constant, it maintains a copy of the difference between the previous packet and the current packets. This data is referred to as the session context ID, which it uses to completely reconstruct the packet header by adding the difference.

BFD Version 1 Support

Platform: Cisco 12000 series

Bidirectional Forwarding Detection (BFD) is a detection protocol designed to provide fast forwarding path failure detection times for all media types, encapsulations, topologies, and routing protocols. In addition to fast forwarding path failure detection, BFD provides a consistent failure detection method for network administrators. Because the network administrator can use BFD to detect forwarding path failures at a uniform rate, rather than the variable rates for different routing protocol hello mechanisms, network profiling and planning will be easier, and reconvergence time will be consistent and predictable.

CBQoS MIB support for Control Plane Policing

Platform: Cisco 12000 series

Cisco IOS Release 12.0(33)S1 adds support on the Cisco 12000 for Control Plane Policing using the CBQoS MIB.

Cisco IOS Flexible Netflow

Platform: Cisco 12000 series

NetFlow is a Cisco IOS technology that provides statistics on packets flowing through a router. NetFlow is the standard for acquiring IP operational data from IP networks. NetFlow provides network and security monitoring, network planning, traffic analysis, and IP accounting.

Flexible NetFlow improves on original NetFlow by adding the capability to customize the traffic analysis parameters for your specific requirements. Flexible NetFlow makes it easier to create more complex configurations for traffic analysis and data export through the use of reusable configuration components.

Color-Aware Policer

Platform: Cisco 12000 series

Cisco IOS Release 12.0(33)S1 provides support for the Color-Aware Policer on Engine-3/Engine-5 line cards for Ethernet over L2TPv3.

The Color-Aware Policer enables a "color-aware" method of traffic policing. This feature allows you to police traffic according to the color classification of a packet. The packet color classification is based on packet matching criteria defined for two user-specified traffic classes—the conform-color class and the exceed-color class. These two traffic classes are created using the conform-color command and the metering rates are defined using the police command.

Field-Programmable Devices Feature Command Enhancement

Platform: Cisco 12000 series

In the Field-Programmable Devices feature, the upgrade hw-module subslot fpd file command replaces the upgrade hw-module subslot command.

H-VPLS with MPLS Edge

Virtual Private LAN Services (VPLS) uses the provider core to join multiple attachment circuits together to simulate a virtual bridge that connects the multiple attachment circuits together. From a customer point of view, there is no topology for VPLS. All of the CE devices appear to connect to a logical bridge emulated by the provider core.

IPv6 over Frame Relay

Platform: Cisco 12000 series

Frame Relay is used as a way to offer multiple service levels for a customer link. The IPv6 over Frame Relay feature allows users to configure IPv6 addresses over Frame Relay physical interfaces and subinterfaces on Engine 3 and Engine 5 line cards in Cisco 12000 series Internet routers and to send IPv6 traffic over the Frame Relay interfaces. The supported Frame Relay encapsulations are Cisco Frame Relay and Internet Engineering Task Force (IETF) Frame Relay.

L2TPv3 Protocol Demultiplexing for IPv6 over HDLC

Platform: Cisco 12000 series

Upgrading a service provider network to support IPv6 is a long and expensive process. As an interim solution, the Protocol Demultiplexing for L2TPv3 feature introduces the ability to provide native IPv6 support by setting up a specialized IPv6 network and offloading IPv6 traffic from the IPv4 network. IPv6 traffic is transparently tunneled to the IPv6 network using L2TPv3 pseudowires without affecting the configuration of the CE routers. IPv4 traffic is routed as usual within the IPv4 network, maintaining the existing performance and reliability of the IPv4 network. Cisco IOS Release 12.0(33)S1 adds support for this feature over HDLC links.

BGP Support for 4-Byte ASN

Platform: Cisco 12000-GRP, Cisco 12000-PRP

The BGP Support for 4-Byte ASN feature introduces support for 4-byte autonomous system numbers. Because of increased demand for autonomous system numbers, in January 2009 the IANA will start to allocate 4-byte autonomous system numbers in the range from 65536 to 4294967295. The Cisco implementation of 4-byte autonomous system numbers uses asplain as the default output display format for autonomous system numbers, but you can configure 4-byte autonomous system numbers in both the asplain format and the asdot format as described in RFC 5396. In addition, the default format for matching 4-byte autonomous system numbers in regular expressions is asplain, so you must ensure that any regular expressions to match 4-byte autonomous system numbers are written in the asplain format. If you want to change the default show command output to display autonomous system numbers in the asdot format, use the bgp asnotation dot command under router configuration mode. When the asdot format is enabled as the default, any regular expressions to match 4-byte autonomous system numbers must be written using the asdot format, or else the regular expression match will fail. Cisco also supports RFC 4893, which was developed to allow BGP to support a gradual transition from 2-byte autonomous system numbers to 4-byte autonomous system numbers.

http://www.cisco.com/univercd/cc/td/doc/product/software/ios120/120newft/120limit/120s/120s32/l2l3comp.htm

Selective MVRF Download

Platform: Cisco 12000

The Selective MVRF Download feature allows Multicast Virtual Routing and Forwarding (MVRF) routing instances to be downloaded to line cards as needed instead of downloading to all line cards. The advantage is that this action saves line card memory by reducing the number of mroutes configured and lowers the use of the CPU by the line card.

This feature is set by default so the ip multicast command is modified with the addition of new keywords to bypass the feature if needed. The modified command is ip multicast mdfs download all. Two new commands show ip mds vrf vpn download interface slot and show ip mds vrf vpn download slot-list are added to monitor this feature.

Two show commands have been changed. For monitoring the MDFS Route Processor, use the show ip multicast command. For the MDFS line card, use the show ip mds vrf vrf_name summary command to display the multicast routes configured on a line card in the context of a VRF. This show command will display a flag indicating the feature was in effect on the line card.

IPv6 Provider Edge Router over MPLS (Cisco 6PE) Enhancement

Platform: Cisco 12000 series

On an IPv6-enabled provider edge (6PE) Cisco 12000 series router, when the edge-facing line card is an IP Services Engine (ISE) line card and when the core-facing line card is an Engine 4, Engine 4+, or Engine 5 line card, disposition performed on 6PE-labeled packets has been accelerated. The acceleration is possible because 6PE-label disposition is now performed in the hardware of the edge-facing ISE line card instead of in the CPU of the core-facing Engine 4, Engine 4+, or Engine 5 line card.

The acceleration applies only to IPv6 6PE-labeled packets. Aggregate 6PE label disposition has not been accelerated, and remains bound by the CPU forwarding performance of the core-facing Engine 4, Engine 4+, or Engine 5 line card.

Support for accelerated disposition on 6PE-labeled packets on Engine 4 and Engine 4+ line cards was introduced in Cisco IOS Release 12.0(28)S. Release 12.0(31)S3 adds support for accelerated disposition on 6PE-labeled packets over VLANs or subinterfaces on Engine 5 line cards.

No new or modified Cisco IOS software commands are introduced with this feature.

Layer 2 Local Switching for Cisco 12000 Series IP Services Engine Line Cards

Platform: Cisco 12000 series

The Layer 2 Local Switching feature allows you to switch Layer 2 data between two interfaces on the same router, and in some cases to switch Layer 2 data between two circuits on the same interface port. Starting in Cisco IOS Release 12.0(31)S2, Layer 2 local switching is supported on customer-facing interfaces on IP Services Engine (ISE) line cards that are installed in a Cisco 12000 series Internet router and configured for a native L2TPv3 tunnel session or an L2TPv3 tunnel session using a tunnel server card.


Note Native L2TPv3 tunnel sessions on customer-facing ISE line cards can coexist with tunnel sessions that use a tunnel server card.


The ISE interface-to-interface switching combinations supported by the Layer 2 local switching feature are:

ATM to ATM

ATM to Ethernet

ATM to Frame-Relay

Ethernet to Ethernet VLAN

Frame Relay to Frame Relay (including Multilink Frame Relay)

On an ISE customer-facing interface, the following types of same-port Layer 2 local switching are also supported:

Same-Port Switching for ATM (PVC and PVP)

Same-Port Switching for Ethernet VLAN

Same-Port Switching for Frame Relay

For more information about this feature, see the Layer 2 Local Switching document:

Layer 2 Tunnel Protocol Version 3 for Cisco 12000 Series IP Services Engine Line Cards

Platform: Cisco 12000 series

The Layer 2 Tunnel Protocol Version 3 (L2TPv3) feature expands on Cisco support of the Layer 2 Tunnel Protocol (L2TP) to tunnel any Layer 2 payload over an IP core network using Layer 2 virtual private networks (VPNs). L2TPv3 simplifies the deployment of VPNs without requiring Multiprotocol Label Switching (MPLS) in the core network.

Starting in Cisco IOS Release 12.0(31)S2, L2TPv3 tunnel sessions (either native L2TPv3 or an L2TPv3 tunnel session that uses a tunnel server card) are supported on customer-facing interfaces on IP Services Engine (ISE) line cards that are installed in a Cisco 12000 series Internet router and configured for Layer 2 local switching.


Note Native L2TPv3 tunnel sessions on customer-facing ISE line cards can coexist with tunnel sessions that use a tunnel server card.


For more information about how to configure and use L2TPv3 tunneling for Layer 2 VPNs, including Layer 2 local switching support in an L2TPv3 tunnel session on an ISE line card, see the Layer 2 Tunnel Protocol Version 3 document:

NPE-G1

Platform: Cisco 7200 VXRrouters

The NPE-G1 is the first network processing engine for the Cisco 7200 VXR routers to provide the functionality of both a network processing engine and an I/O controller. If used without an I/O controller, an I/O blank panel must be in place.

While its design provides I/O controller functionality, it can also work with any I/O controller supported in the Cisco 7200 VXR routers. When installed with an I/O controller, the NPE-G1provides the primary input/out functionality; that is, the NPE-G1 input/out functionality enhances that of the existing I/O controller.

The NPE-G1 maintains and executes the system management functions for the Cisco 7200 VXR routers and also holds the system memory and environmental monitoring functions.

The NPE-G1 consists of one board with multiple interfaces. It is keyed so that it can be used only in the Cisco 7200 VXR routers.

ATM OAM AIS-RDI Monitoring

Platform: Cisco 10000 series, Cisco 10720

The ATM OAM AIS-RDI Monitoring feature extends the existing ATM virtual circuit Operation, Administration, and Maintenance (OAM) functionality to include monitoring of the Alarm Indication Signal-Remote Defect Indication (AIS-RDI). Once the feature is enabled, OAM AIS-RDI is monitored on the virtual circuit (VC).

If the number of consecutive OAM AIS-RDI cells received is greater than a configurable number, the VC is brought down. The VC is brought up when there are no OAM AIS-RDI cells received within a configurable interval.

Use the oam ais-rdi command to specify the number of consecutive OAM AIS-RDI cells that are to be received before the permanent virtual circuit (PVC) is brought down. The no form of the command returns the OAM AIS-RDI function to the default configuration.

[no] oam ais-rdi [down-count [up-count]]

The down-count argument is the number of consecutive OAM AIS-RDI cells received. The range is from 1 to 60, and the default is 1 OAM AIS-RDI cell.

The down-count argument is the number of consecutive OAM AIS-RDI cells received. The range is from 1 to 60, and the default is 1 OAM AIS-RDI cell.

The up-count argument is the number of seconds that are allowed to elapse with no OAM AIS-RDI cells received. The range is from 3 to 60 seconds, and the default is 3.

ATM VC Bundles to MPLS VRF

Platform: Cisco 12000 series

The ATM VC Bundles to MPLS VRF feature is an extension of the IP-to-ATM Class of Service feature suite. The IP to ATM Class of Service feature suite, using virtual circuit (VC) support and bundle management, maps quality of service (QoS) characteristics between IP and ATM. It provides customers who have multiple VCs (with varying qualities of service to the same destination) with the ability to build a QoS differentiated network.

The ATM VC Bundles to MPLS VRF feature enables use Multiprotocol Label Switching (MPLS) VPN routing and forwarding (VRF) as an additional selection criteria for packet forwarding. When a provider edge device learns an IP prefix from a customer edge device, it will assign a label to this route. All traffic with that prefix will now be mapped to this VPN label. This works with ATM bundles because the IP prefix associated with the bundle is used to create the VPN label. VPN forwarding takes place just as it does for nonbundled interfaces. The only difference is at the PE, when it switches to the bundle interface in the MPLS-to-IP path. At that point it uses the different VCs for the different precedence traffic as listed in its member adjacency table.

To enable ATM VC bundles to MPLS VRF, use the ip vrf command. The following example creates the VPN bundle on interface ATM0.35:

interface ATM0.35 point-to-point

ip address 10.10.10.10 255.255.255.252

ip vrf forwarding bundle_vpn

CNS Interactive CLI

Platforms: Cisco 7200 series, Cisco 7500 series, Cisco 10000 series

Network management applications can use Cisco Networking Services (CNS) agents to manage network routers. The CNS exec agent provides the capability to send commands to a router from a programmable source. The CNS Interactive CLI feature introduces a new XML interface that allows you to send interactive commands to a router, such as commands that generate prompts for user input. A benefit of this feature is that interactive commands can be aborted before they have been fully processed. For example, for commands that generate a significant amount of output, the XML interface can be customized to limit the size of the output or the length of time allowed for the output to accumulate. The capability to use a programmable interface to abort a command before its normal termination (similar to manually aborting a command) can greatly increase the efficiency of diagnostic applications that might use this functionality. The new XML interface also allows for multiple commands to be processed in a single session. The response for each command is packaged together and sent in a single response event.

Distributed ATM OAM Support (dOAM)

Platform: Cisco 12000 series

For detailed information about this feature, see the following document:

http://www.cisco.com/univercd/cc/td/doc/product/software/ios120/120newft/120limit/120s/120s28/12sfrcdb.htm

Frame Relay Scalability Conditional Debug Support

Platforms: Cisco 7200 series, Cisco 7500 series, Cisco 10000 series, Cisco 12000 series

For detailed information about this feature, see the following document:

http://www.cisco.com/univercd/cc/td/doc/product/software/ios120/120newft/120limit/120s/120s28/fmconde.htm

FRF.1.2 Annex A support

Platforms: Cisco 7200 series, Cisco 7500 series, Cisco 10000 series, Cisco 12000 series

The FRF.1.2 Annex A Support feature is also known as Local Management Interface (LMI) segmentation and supports an enhancement to the Frame Relay LMI protocol where LMI full status messages are segmented because MTU constraints or large numbers of permanent virtual circuits (PVCs). This feature is useful when the MTU size cannot be increased but is insufficient to accommodate the large number of PVCs on the link. During Frame Relay internetworking with other Layer 2 protocols, the MTUs on each interface must match. In software without the FRF.1.2 Annex A Support feature, users cannot change the MTU size on the Frame Relay side and place all the PVC data into one LMI packet. With the FRF.1.2 Annex A Support functionality, this problem is solved.

The FRF.1.2 Annex A standard adds a new message type "Full status continued" to an LMI packet. When a DCE determines that it cannot fit all PVCs into one packet (enforced by the MTU size), the message type is set to "Full status continued." The DTE responds to "Full status continued" messages sent to this packet immediately instead of waiting for the T391 timer to expire. The DCE sends the remaining PVCs in one or more "Full status continued" messages until all the remaining PVCs can fit into one message. At this point, a normal "Full status" message is sent.

If the DTE receives a "Full status" or "Full status continued" STATUS message in response to a "Full status continued" STATUS ENQUIRY message, this exchange indicates a lower-valued data-link connection identifier (DLCI) than the previous "Full status continued" STATUS message and is considered to be an error event and PVC information elements (IEs) will not be processed. The next time the T391 timer expires, the "Full status" STATUS ENQUIRY procedure is reinitiated.

This feature follows the FRF1.2 implement agreement [1] and allows the Cisco IOS software to be compliant with the FRF1.2 standard. The implementation is platform-independent and applies to all platforms running Cisco IOS software that support Frame Relay. This feature interoperates only with existing Cisco IOS software releases where all PVCs can be reported in one packet. A router running the new functionality must be able to interoperate with routers running existing Cisco IOS software releases and with routers that support the new functionality using the continuation status request and reply frames. Only LMI types Q.933A and ANSI support the FRF.1.2 Annex A standard.

You can track "Full status continued" packets using the debug frame-relay lmi privileged EXEC command. An extra field, 04, has been added to the display output. The following example indicates where in the report to look for this field (text in bold for purpose of example):

17:42:39: Serial1(out): StEnq, myseq 126, yourseen 125, DTE up

17:42:39: datagramstart = 0x40058DA4, datagramsize = 13

17:42:39: FR encap = 0x00010308

17:42:39: 00 75 51 01 04 53 02 7E 7D

The string segment "active/inactive" in the show interface commands indicates whether the FRF.1.2 Annex A standard is triggered. The report indicates active when routers receive the "Full status continued" message; otherwise, the report indicates inactive.

Quality of Service (QoS) Features

QoS for IPv6

Platform: Cisco 12000 series

Starting in Cisco IOS Release 12.0(28)S, the following quality of service (QoS) features are supported in IP version 6 (IPv6) environments on IP Service Engine (ISE) line cards:

Packet classification

Traffic shaping

Traffic policing

Packet marking/remarking

Queueing

WRED-based drop


Note QoS policy propagation through the Border Gateway Protocol (QPPB) is not supported.


These IPv6 QoS features are supported only in hardware-based fast-path forwarding on ISE line cards. IPv6 QoS is not supported in slow-path forwarding.

IPv6 QoS is not supported on the following ISE line cards:

1-port channelized OC-12/STM-4 (DS1/E1)

2-port OC-12/STM-4 DPT

4-port OC-12/STM-4 ATM

All of the QoS features available for IPv6 environments are managed from the modular QoS CLI (MQC). The MQC is a command-line interface that allows you to define traffic classes, create and configure traffic policies (policy maps), and then attach those traffic policies to interfaces. For detailed information about how to use the MQC, see the Cisco IOS Quality of Service Solutions Configuration Guide, Release 12.3, at the following location:

http://www.cisco.com/univercd/cc/td/doc/product/software/ios123/123cgcr/qos_vcg.htm

In addition to the existing MQC commands supported on the Cisco 12000 series Internet router, the following new and modified commands are also supported on ISE line cards in class-map configuration mode:

match protocol {ip | ipv6}

Specifies whether the IPv4 or the IPv6 protocol is to be used as match criteria for a traffic class. If you do not use the match protocol command, the traffic class matches both IPv4 and IPv6 packets.

match access-group name ipv6-access-group

Specifies the name of an IPv6 access list against whose contents packets are checked to determine if they belong to the traffic class.

match [ip] dscp dscp-value
match [ip] precedence precedence-value

Specifies a differentiated services code point (DSCP) or IP precedence value to be used as match criteria to classify packets in a traffic class.

If you specify the ip keyword, the IP precedence or DSCP value is used to match only IPv4 packets in a traffic class. If you do not specify the ip keyword, the IP precedence or DSCP value is used to match both IPv4 and IPv6 packets.


Note The IP DSCP value is the first six bits in the ToS byte, while the IP precedence value is the first three bits in the ToS value. The IP precedence value is actually part of the IP DSCP value. Therefore, both values cannot be matched simultaneously. If both values are set simultaneously, the packet is matched with the IP DSCP value.


The following modified command is supported on ISE line cards in policy-map configuration mode:

set [ip] dscp dscp-value
set [ip] precedence precedence-value

Sets the DSCP or IP precedence value in packet headers for a specified traffic class. Once the DSCP or IP precedence bits are set, other QoS services such as Weighted Random Early Detection (WRED) then operate on the bit settings.

The ip keyword is optional and supports backward compatibility with the IPv4 QoS commands. The set [ip] dscp and set [ip] precedence commands apply to both IPv4 and IPv6 traffic whether you enter the ip keyword or not.


Note The set precedence command cannot be used with the set dscp command to mark the same packet. The two values, DSCP and precedence, are mutually exclusive. A packet can have one value or the other, but not both.

Scalability Enhancements on Cisco 12000 Series 4-Port ATM ISE Line Cards

Platform: Cisco 12000 series

The Cisco 12000 series router, 4-port OC-3c/STM-1 and 4-port OC-12c/STM-4c ATM IP Services Engine (ISE) line cards are enhanced so that quality of service (QoS) policy maps applied to virtual circuits (VCs) can optimize their use of Ternary Content Addressable Memory (TCAM) space. This enhancement provides the following performance improvements:

Reduction in the number of TCAM entries required, as individual TCAM entries are used for multiple VCs.

Reduction in the amount of Route Processor (RP) memory.

Reduction of overall merge time for TCAM entries.

Prior releases of the software provided for sharing of policy maps between VCs if all classes in the policy map could be shared. This greatly limited the use of the sharing, because if even one class in the policy map could not be shared, the entire policy map was unshared. This enhancement provides for sharing of individual classes between VCs.

When classes in a policy map are shared between VCs, the amount of TCAM space can be reduced in proportion to the number of VCs that use these classes. In many cases, this greatly reduces the amount of TCAM space required to store QoS policy maps applied to VCs.

Route Processor (RP) memory is reduced in proportion to the number of VCs that have shared classes. This is because a single instance of each class is stored on the RP and is used by all VCs on a line card that are configured with the same class.

In addition, the overall merge time for TCAM entries on all VCs that are configured with the same policy map in the same (ingress or egress) direction is reduced in proportion to the number of VCs using these TCAM entries.

A class in a policy map is shared, except in the following instances:

The class is part of a policy map that uses percentage-based policing. In this instance, all classes in the policy map are unshared between VCs with different available bandwidths. For more information on percentage-based policing, see QoS: Percentage-Based Policing at http://www.cisco.com/univercd/cc/td/doc/product/software/ios120/120newft/120limit/120s/120s28/12spctpg.htm.

The class is part of an ingress policy map that contains at least one shape command. In this instance, all classes in the policy map are unshared.

The class contains at least one police statement.

Restriction

QoS statistics for shared classes, other than class-default, are available only on an egress traffic policy when the shared class has a bandwidth or priority command defined in the policy map. This is a result of the optimization of TCAM resources. Otherwise, the shared classes have no matched per-class statistics by default. QoS statistics will be available for class-default on an egress traffic policy if all of the other classes in the policy map have priority or bandwidth command defined for them or if class-default is unshared.

QoS statistics for shared classes are not available on an ingress traffic policy.

For a shared class in which QoS statistics are not available, you can disable the sharing and the optimization of TCAM entries for this class and thereby enable the QoS statistics. To enable QoS statistics for a traffic class in a shared class, it is recommended that you add a police command to the traffic class and configure the cir (committed information rate) parameter to its maximum value and the conform-action and exceed-action parameters as a transmit action. QoS statistics that were previously unavailable for a traffic class will now be displayed, however the class will be unshared. This applies to class-default as well.

The command syntax of the police (two rates) command is as follows:

Router(config-pmap-c)# police cir {cir_bps | percent cir_per} [bc conform-burst] {pir pir_bps} [be peak-burst] [conform-action action [exceed-action action [violate-action action]]]

Dynamic Time Slot Configuration

Platform: Cisco 10000 series

The Dynamic Time Slot Configuration feature automatically reconfigures an existing channel group with different time slot allocations. You no longer are required to remove and recreate the channel group with the desired allocation.

On the Cisco 10000 router, you can create channel groups using available time slots on the following channelized line cards:

Channelized T3

Channelized OC-12

Channelized STM-1

Channelized E1/T1

In previous releases, once you configure channel groups, you cannot modify their time slot allocations without first deleting the channel group. After recreating the channel group with the different time slot allocations, you then recreate the interface and subinterfaces associated with the channel group.

The Dynamic Time Slot Configuration feature eliminates the requirement for manual reconfiguration. Instead, the reconfiguration of time slots on channelized line cards occurs automatically.

IPv6 Provider Edge Router over MPLS (Cisco 6PE) Enhancement

Platform: Cisco 12000 series

On an IPv6-enabled provider edge (6PE) Cisco 12000 Series Internet Router, when the edge-facing line card is IP Services Engine (ISE) and the core-facing line card is Engine 4 or Engine 4+, disposition performed on 6PE-labeled packets has been accelerated. The acceleration is possible because 6PE-label disposition is now performed on the hardware of the edge-facing ISE line card instead of on the CPU of the core-facing Engine 4 or Engine 4+ line card.

The acceleration applies only to IPv6 6PE-labeled packets. Aggregate 6PE label disposition has not been accelerated, and remains bound by the CPU forwarding performance on the core-facing Engine 4 or Engine 4+ line card.

No new or modified Cisco IOS software commands are introduced with this feature.

Cisco 12000 Series 4-Port OC-12c/STM-4c DPT ISE Line Card Enhancements

Platform: Cisco 12000 series

New software features have been added to the Cisco 12000 series 4-port OC-12c/STM-4c Dynamic Packet Transport (DPT) IP Services Engine (ISE) line card. Starting in Cisco IOS Release 12.0(26)S, the following software features are now supported on the 4-port OC-12c/STM-4c DPT ISE line card:

Stateful Switchover (SSO)

IPv6

Error Recovery Enhancements

MPLS Functionality

Multicast Forwarding

Stateful Switchover (SSO)


Note The Stateful Switchover (SSO) feature was introduced in Cisco IOS Release 12.0(22)S. This release introduces the feature on the 4-port OC-12c/STM-4c DPT ISE line card.


The Stateful Switchover (SSO) feature is an incremental step within an overall program to improve the availability of networks constructed with Cisco IOS routers. SSO is particularly useful at the network edge. Traditionally, core routers protect against network faults using router redundancy and mesh connections that allow traffic to bypass failed network elements. SSO provides protection for network edge devices with dual Route Processors (RPs) that represent a single point of failure in the network design, and where an outage might result in loss of service for customers.

In specific Cisco networking devices that support dual RPs, SSO takes advantage of RP redundancy to increase network availability. The SSO feature takes advantage of RP redundancy by establishing one of the RPs as the active processor while the other RP is designated as the standby processor, and then synchronizing critical state information between them. Following an initial synchronization between the two processors, SSO dynamically maintains RP state information between them.

A switchover from the active to the standby processor occurs when the active RP fails, is removed from the networking device, or is manually taken down for maintenance.

SSO is used with the Cisco Nonstop Forwarding (NSF) feature. Cisco NSF allows for the forwarding of data packets to continue along known routes while the routing protocol information is being restored following a switchover. With Cisco NSF, peer networking devices do not experience routing flaps, thereby reducing loss of service outages for customers.

For more information about the Stateful Switchover feature, see the following document:

http://www.cisco.com/univercd/cc/td/doc/product/software/ios120/120newft/120limit/120s/120s24/sso24s.htm

IPv6


Note IP version 6 (IPv6) was introduced in Cisco IOS Release 12.0(22)S. This release introduces IPv6 on the 4-port OC-12c/STM-4c DPT ISE line card.


IP is a packet-based protocol used to exchange data, voice, and video traffic over digital networks. IP handles addressing, fragmentation, reassembly, and protocol demultiplexing. It is the foundation on which all other IP protocols (collectively referred to as the IP Protocol suite) are built. As a network-layer protocol, IP contains addressing and control information that allows data packets to be routed. IPv6, formerly called IPng (next generation), is the latest version of IP and offers many benefits, such as a larger address space, over the previous version of IP (version 4).

For more information, see the IPv6 for Cisco IOS Software document at the following location:

http://www.cisco.com/univercd/cc/td/doc/product/software/ios122/122newft/122t/122t2/ipv6/index.htm

Error Recovery Enhancements

Error recovery on 4-port OC-12c/STM-4c DPT ISE line cards has been enhanced to include more comprehensive hardware failure detection and an improved recovery process. The boot time following hardware failures has also been minimized.

MPLS Functionality

In addition to MPLS Virtual Private Networks on the 4-Port OC-12c/STM-4c DPT ISE Line Card, which was introduced in Cisco IOS Release 12.0(25)S, the following Multiprotocol Label Switching (MPLS) features are now supported on the 4-port OC-12c/STM-4c DPT ISE line card:

MPLS Quality of Service (QoS)

The MPLS Quality of Service (QoS) feature was introduced in Cisco IOS Release 12.0(22)S. This release introduces the MPLS Quality of Service (QoS) feature on the 4-port OC-12c/STM-4c DPT ISE line card.

The MPLS Quality of Service (QoS) feature enables service providers to set the MPLS experimental field value without modifying the value of the IP precedence field in IP packets that are transported through an MPLS core network. By choosing different values for the MPLS experimental field, service providers can mark packets according to their characteristics, such as rate or type, so that packets have the priority that they require during periods of congestion.

For more information about how to use and configure the MPLS Quality of Service (QoS) feature, see the Cisco document at the following location:

http://www.cisco.com/univercd/cc/td/doc/product/software/ios120/120newft/120limit/120st/120st14mct/1214t.htm

MPLS Time To Live (TTL) Propagation from IP

The MPLS Time To Live (TTL) Propagation from IP feature was introduced in Cisco IOS Release 12.0(24)S for Engine 4+ DPT line cards. This release introduces the MPLS Time To Live (TTL) Propagation from IP feature on the 4-port OC-12c/STM-4c DPT ISE line card.

To control the generation of the time to live (TTL) field in the MPLS header when labels are first added to an IP packet, the 4-port OC-12c/STM-4c DPT ISE line card supports the use of the mpls ip propagate-ttl global configuration command.

For more information about this command, see the Cisco document at the following location:

Note The Multicast Forwarding feature was introduced in Cisco IOS Release 12.0(21)S. This release introduces the Multicast Forwarding feature on the 4-port OC-12c/STM-4c DPT ISE line card.


The Multicast Forwarding feature on the 4-port OC-12c/STM-4c DPT ISE line card allows hardware-based fast forwarding of IP version 4 (IPv4) multicast traffic, resulting in high throughputs and performance.

For more information about the hardware forwarding of IP multicast packets and how to enable hardware forwarding on DPT ISE line cards, see the Cisco document at the following location:

Cisco 12000 Series 8-Port OC-3/STM-1 ATM Line Card Enhancements

Platform: Cisco 12000 series

Starting in Cisco IOS Release 12.0(26)S, the following software features are now supported on Cisco 12000 series 8-port OC-3/STM-1 ATM line cards:

ATM AAL5 and ATM Cell Relay Supported on the Same Port on Cisco 12000 Series 8-Port OC-3/STM-1 ATM Line Cards

IP Packet Precedence Marking on Cisco 12000 Series 8-Port OC-3/STM-1 ATM Line Cards

Sampled NetFlow and MPLS-aware NetFlow on Cisco 12000 Series 8-Port OC-3/STM-1 ATM Line Cards

ATM AAL5 and ATM Cell Relay Supported on the Same Port on Cisco 12000 Series 8-Port OC-3/STM-1 ATM Line Cards

Cisco 12000 series 8-port OC-3/STM-1 ATM line cards now support, by default, the Any Transport over MPLS (AToM): ATM Cell Relay over MPLS feature in both virtual circuit (VC) mode and virtual path (VP) mode and the configuration of the Any Transport over MPLS: ATM AAL5 over MPLS feature on the same port. In this section, both the Any Transport over MPLS (AToM): ATM Cell Relay over MPLS: VC Mode feature and the Any Transport over MPLS (AToM): ATM Cell Relay over MPLS: VP Mode feature are referred to as the ATM Cell Relay over MPLS: Single Cell Relay feature.

Starting in Cisco IOS Release 12.0(26)S, you no longer need to use the atm mode cell-relay interface configuration command to enable an 8-port OC-3/STM-1 ATM interface to send and receive ATM packets as part of the ATM Cell Relay over MPLS: Single Cell Relay feature.

Another restriction that has been removed from configuring the ATM Cell Relay over MPLS: Single Cell Relay feature on an 8-port OC-3/STM-1 ATM line card is that a corresponding port is no longer reserved for this feature. For example, in Cisco IOS Release 12.0(25)S, if you configure the ATM Cell Relay over MPLS: Single Cell Relay feature on port 0, port 1 is also reserved. Likewise, ports 2 and 3, ports 4 and 5, and ports 6 and 7 are reserved when you configure the ATM Cell Relay over MPLS: Single Cell Relay feature on either port in the pair.

In addition, in Cisco IOS Release 12.0(25)S, if you configure an 8-port OC-3/STM-1 ATM port for the Any Transport over MPLS: ATM AAL5 over MPLS feature and then configure the ATM Cell Relay over MPLS: Single Cell Relay feature on that port, the VCs and VPs for AAL5 on the port and its corresponding port were removed. Starting in Cisco IOS Release 12.0(26)S, this behavior no longer occurs. The Any Transport over MPLS: ATM AAL5 over MPLS feature and the ATM Cell Relay over MPLS: Single Cell Relay feature are supported on the same port.

Any Transport over MPLS (AToM) transports Layer 2 packets over a Multiprotocol Label Switching (MPLS) backbone. ATM single cell relay is one type of Layer 2 traffic that can be transported using AToM over an MPLS network core. For information about how to configure the ATM Cell Relay over MPLS: Single Cell Relay feature and the restrictions that existed in earlier Cisco IOS software releases, see the Any Transport over MPLS document at the following Cisco location:

IP Packet Precedence Marking on Cisco 12000 Series 8-Port OC-3/STM-1 ATM Line Cards


Note The IP Packet Precedence Marking feature was introduced in Cisco IOS Release 12.0(22)S on the Cisco 12000 series Engine 2 Packet-over-SONET (POS) line cards. This release introduces the feature on Cisco 12000 series 8-port OC-3/STM-1 ATM line cards.


The IP Packet Precedence Marking feature is supported on 8-port OC-3/STM-1 ATM line cards. This feature is implemented in the Packet Switching ASIC (PSA) for fast path forwarding and in the line card switching software for slow path forwarding.

In the modular QoS CLI (MQC), you use the set ip precedence ip-precedence-value policy-map configuration command to set the precedence value in IP headers for a specified traffic class.


Note On 8-port OC-3/STM-1 ATM line cards, you can use the set ip precedence ip-precedence-value policy-map configuration command in a quality of service (QoS) policy configuration only with the default traffic class.


Usage Guidelines

On 8-port OC-3/STM-1 ATM line cards, IP packet precedence marking is implemented as follows:

IP packet precedence marking is performed on an individual virtual circuit (VC) basis in the ingress direction. IP packets received on the VC are marked irrespective of the packet switching behavior of the egress port. The QoS treatment of the packet is based on the new precedence bits set with the set ip precedence ip-precedence-value policy-map configuration command, not the original precedence bits received in the packet.

If a received IP packet is forwarded on an MPLS label-switched path (LSP), the experimental bits in the MPLS label are given the value of the precedence bit configured with the set ip precedence ip-precedence-value policy-map configuration command.

IP packet precedence marking is disabled by default. VC traffic is forwarded "as is" with no special QoS action.

Restrictions

The following restrictions apply to IP packet precedence marking on 8-port OC-3/STM-1 ATM line cards:

You can configure the IP precedence bit with the set ip precedence ip-precedence-value policy-map configuration command only on a per-PVC basis.

The set ip precedence ip-precedence-value policy-map configuration command is not supported on a PVC configured as l2transport.

Configuration Example

The following example shows how to set the precedence value in IP headers to 5 for the service policy ip_color1 configured for the default traffic class, and then attach the policy to an ATM virtual circuit on an 8-port OC-3/STM-1 ATM line card.

router(config)# policy-map ip_color1

router(config-pmap)# class class-default

router(config-pmap-c)# set ip precedence 5

router(config-pmap-c)# end

!

router(config)# interface atm 3/0.1 point-to-point

router(config-subif)# pvc 10/10

router(config-if-atm-vc)# service-policy input ip_color1

router(config-if-atm-vc)# end

Sampled NetFlow and MPLS-aware NetFlow on Cisco 12000 Series 8-Port OC-3/STM-1 ATM Line Cards

Cisco 12000 series 8-port OC-3/STM-1 ATM line cards now support the Sampled NetFlow and Multiprotocol Label Switching (MPLS)-aware NetFlow features.


Note The Sampled Netflow feature was introduced in Cisco IOS Release 12.0(11)S; the MPLS-aware NetFlow feature was introduced in Cisco IOS Release 12.0(24)S.


The Sampled NetFlow feature enables you to sample one out of many IP packets that are being forwarded to an interface. Sampled packets are accounted for in the NetFlow flow cache of the router. Sampling packets substantially decreases the CPU utilization that is needed to account for NetFlow packets, by allowing the majority of the packets to be switched faster because they do not require additional NetFlow processing. For information about how to configure and use Sampled NetFlow, see the Cisco document at the following location:

http://www.cisco.com/univercd/cc/td/doc/product/software/ios120/120newft/120limit/120s/120s11/12s_sanf.htm

MPLS-aware NetFlow is an extension of the NetFlow feature. NetFlow traditionally provides statistics for IP version 4 (IPv4) traffic. MPLS-aware NetFlow provides per-flow statistics for traffic in MPLS-enabled networks. The network administrator can turn on MPLS-aware NetFlow inside an MPLS cloud on a subset of provider (P) backbone routers. These routers can export MPLS-aware NetFlow data in real time to an external NetFlow collector device for further processing or to a data terminal for analysis. MPLS-aware NetFlow statistics can be used for detailed MPLS traffic studies and analysis. For additional information, see the Cisco document at the following location:

Cisco 12000 Series ISE and E4+ Line Card MQC Enhancements

Platform: Cisco 12000 series

Cisco 12000 series IP Services Engine (ISE) and Engine 4 Plus (E4+) line cards now support an enhanced set of modular QoS CLI (MQC) commands for the following line card types:

Packet-over-SONET (POS) ISE

Gigabit Ethernet (GE) ISE

ATM ISE

E4+ POS

E4+ GE

New Commands

Table 8 lists and describes the new MQC commands supported on ISE and E4+ line cards.

Table 8 MQC Commands Supported on Cisco 12000 Series ISE and E4+ Line Cards 

MQC Command
Description

match ip dscp

Configures a specific IP differentiated service code point (DSCP) value as a match criterion.

match mpls experimental

Configures a class map to use the specified value of the EXP field as a match criterion.

match qos-group

Configures a specific QoS group value as a match criterion.

random-detect discard-class-based

Enables weighted random early detection (WRED) so that it is based on the discard class value of a packet.

set discard-class

Marks a packet with a discard-class value that describes its per-hop behavior (PHB) for dropping traffic.

set ip dscp

Marks a packet by setting the IP differentiated services code point (DSCP) in the type of service (ToS) byte.

set ip precedence

Configures the precedence value in the IP header.

set mpls experimental imposition1

Configures the value of the Multiprotocol Label Switching (MPLS) EXP field in all imposed label entries at an input interface.

set mpls experimental topmost

Configures the MPLS EXP field value in the topmost MPLS label header at an input and/or output interface.

set qos-group2

Configures a group ID so that it can be used later to classify packets.

1 The set mpls experimental imposition command is supported only on the input interfaces of POS ISE, GE ISE, ATM ISE, ES+ POS, and E4+ Ethernet line cards.

2 The set qos-group command is supported only on the input interfaces of ISE and E4+ line cards. Up to eight QoS groups are supported per line card. The valid values for the set qos-group command are from 0 to 7; 0 is the default for the qos-group keyword.


The enhanced MQC command set is implemented in the following ways on Cisco 12000 series ISE and E4+ line cards:

Although E4+ line cards support MQC QoS configuration only on physical interfaces, an E4+ Ethernet line card can support input access control lists (ACLs) for a VLAN.

Packet-over-SONET and Gigabit Ethernet ISE line cards support MQC QoS configuration on both physical interfaces and subinterfaces. ATM ISE line cards support MQC QoS configuration on virtual circuits (VCs).

When a Cisco 12000 series is used as a Provider Edge (PE) router, the set qos-group and set discard-class commands support pipe mode on output interfaces only for the following combinations of output interfaces:

Core-Facing Interface
Customer Network-Facing Interface

E2

ISE

ISE

ISE

E4+

ISE

E4+

E4+


Restrictions

The following restrictions apply to pipe mode between Cisco 12000 series output interfaces:

If the core-facing output interface is E4+, you must configure the set qos-group ID as a value between 0 and 7.

Pipe mode is only partially supported between E2 core-facing and ISE customer-facing output interfaces. The only parameter that is sent from the E2 to the ISE interface is the set qos-group value (the set discard-class value is not sent), which is identically mapped to the E2 exp-value of the exposed label. On the ISE interface, scheduling is performed using the match qos-group command.

On ISE and E4+ line cards, the MPLS experimental (EXP) value is automatically propagated from the null label to the exposed label.

On ISE line cards, the set discard-class command is supported as one of the possible traffic policing actions that you can configure with the police command.

On ISE and E4+ line cards, the set mpls experimental imposition and set mpls experimental topmost commands are supported as possible traffic policing actions that you can configure with the police command.

Eight levels of quality of service are provided for ISE ToFab queues, instead of only two levels supported in earlier releases.

ToFab queue and output queue selection is based on the remarked packets.

Weighted Random Early Detection (WRED) enabled on an output interface is based on the remarked packets sent to the output interface.

MPLS DiffServ Tunneling Modes

The following MQC commands are supported on Cisco 12000 series ISE and E4+ line cards to configure the MPLS DiffServ Tunneling Modes feature:

match qos-group

set discard-class

set mpls experimental imposition

set mpls experimental topmost

set discard-class

The MPLS DiffServ Tunneling Modes feature allows service providers to manage the quality of service that a router will provide to a Multiprotocol Label Switching (MPLS) packet in an MPLS network. The MPLS DiffServ Tunneling Modes feature conforms to the IETF draft standard for Uniform, Short Pipe, and Pipe modes. It also conforms to Cisco-defined extensions for scalable command-line interface (CLI) management of those modes at customer edge, provider edge, and core routers.

CISCO-ATM-EXT-MIB

Platform: Cisco 12000 series

The CISCO-ATM-EXT-MIB has been enhanced to include support for Operation, Administration, and Maintenance (OAM) parameters used to manage ATM permanent virtual circuits (PVCs). OAM ensures that no packets are lost by allowing a PVC to go down if there is a disruption along its path, such as if network connectivity is lost. A new table is added to the CISCO-ATM-EXT-MIB that contains OAM configuration and PVC state information.

No new or modified Cisco IOS commands are associated with this MIB. For details on managed objects within the CISCO-ATM-EXT-MIB, see the CISCO-ATM-EXT-MIB.my MIB file, available from the Cisco MIB FTP site at the following location:

Digital-link Subrate Scramble for Cisco 12000 Series 6-Port E3 and 12-Port E3 Line Cards

Platform: Cisco 12000 series

The 6-port E3 (6E3-SMB) and 12-port E3 (12E3-SMB) line cards for the Cisco 12000 series now support interoperating with the Cisco 7200 series and Cisco 7500 series 1-port E3 serial port adapter (PA-E3) and 2-port E3 serial port adapter (PA-2E3) when subrate and scrambling are enabled in digital-link mode. The Digital-link Subrate Scramble feature enhances interoperability between the 6E3-SMB and 12E3-SMB line cards and the PA-E3 and PA-2E3 port adapters. Subrate means that the configured bandwidth of the interface is less than the full default rate of 34,010 kbps.

To implement the Digital-link Subrate Scramble feature, enter the scramble before subrate processing interface configuration command. The before subrate processing option performs scrambling before the data has gone through subrate processing.

The configuration scenarios that are shown in Table 9 should be used when attempting interoperability between the 6E3-SMB and 12E3-SMB line cards and the PA-E3 and PA-2E3 port adapters.

Integrated IS-IS Multitopology Support for IPv6

Platforms: Cisco 10720, Cisco 12000 series

The Integrated IS-IS Multitopology Support for IPv6 feature enables Intermediate System-to-Intermediate System (IS-IS) to maintain a set of independent topologies within a single area or domain. This mode removes the restriction that all interfaces on which IS-IS is configured must support the identical set of network address families. It also removes the restriction that all routers in the IS-IS area (for Level 1 routing) or domain (for Level 2 routing) must support the identical set of network layer address families. Because multiple shortest path first (SPF) calculations are performed, one for each configured topology, it is sufficient that connectivity exists among a subset of the routers i
