Introduction

Cisco IOS XR Software is a distributed operating system designed for continuous system operation combined with service flexibility and high performance.

Cisco IOS XR Software running on the Cisco ASR 9000 Series Aggregation Services Router provides the following features and benefits:

IP and Routing—This supports a wide range of IPv4 and IPv6 services and routing protocols; such as Border Gateway Protocol (BGP), Routing Information Protocol (RIPv2), Intermediate System-to-Intermediate System (IS-IS), Open Shortest Path First (OSPF), IP Multicast, Routing Policy Language (RPL), Hot Standby Router Protocol (HSRP), and Virtual Router Redundancy Protocol features (VRRP).

Ethernet Services—The Cisco IOS XR Software Release 4.2 running on the Cisco ASR 9000 Series Aggregation Services Router supports the following Ethernet features:

Ethernet Virtual Connections (EVCs)

Flexible VLAN classification

Flexible VLAN translation

IEEE bridging

IEEE 802.1s Multiple Spanning Tree (MST)

MST Access Gateway

L2VPN

Virtual Private LAN Services (VPLS), Hierarchical VPLS (H-VPLS), Virtual Private Wire Service (VPWS), Ethernet over MPLS (EoMPLS), pseudo wire redundancy, and multi segment pseudo wire stitching

BGP Prefix Independent Convergence—This provides the ability to converge BGP routes within sub seconds instead of multiple seconds. The Forwarding Information Base (FIB) is updated, independent of a prefix, to converge multiple 100K BGP routes with the occurrence of a single failure. This convergence is applicable to both core and edge failures and with or without MPLS. This fast convergence innovation is unique to Cisco IOS XR Software.

Multiprotocol Label Switching (MPLS)This supports MPLS protocols, including Traffic Engineering (TE) [including TE-FRR and TE Preferred Path], Resource Reservation Protocol (RSVP), Label Distribution Protocol (LDP), Targeted LDP (T-LDP), Differentiated Services (DiffServ)-aware traffic engineering, and Layer 3 Virtual Private Network (L3VPN).

Multicast—This provides comprehensive IP Multicast software including Source Specific Multicast (SSM) and Protocol Independent Multicast (PIM) in Sparse Mode only. The Cisco ASR 9000 Series Aggregation Services Router also supports Auto-Rendezvous Point (AutoRP), Multiprotocol BGP (MBGP), Multicast Source Discovery Protocol (MSDP), Internet Group Management Protocol Versions 2 and 3 (IGMPv2 and v3), and IGMPv2 and v3 snooping.

Quality of Service (QoS)—This supports QoS mechanisms including policing, marking, queuing, random and hard traffic dropping, and shaping. Additionally, Cisco IOS XR supports modular QoS command-line interface (MQC). MQC is used to configure various QoS features on various Cisco platforms, including the Cisco ASR 9000 Series Aggregation Services Router. Supports the following:

Class-Based Weighted Fair Queuing (CBWFQ)

Weighted Random Early Detection (WRED)

Priority Queuing with propagation

2-rate 3-color (2R3C) Policing

Modular QoS CLI (MQC)

4-level Hierarchical-QoS

Shared Policy Instances

Manageability—This provides industry-standard management interfaces including modular command-line interface (CLI), Simple Network Management Protocol (SNMP), and native Extensible Markup Language (XML) interfaces. Includes a comprehensive set of Syslog messaging.

Security—This provides comprehensive network security features including Layer 2 and Layer 3access control lists (ACLs); routing authentications; Authentication, Authorization, and Accounting (AAA)/Terminal Access Controller Access Control System (TACACS+), Secure Shell (SSH), Management Plane Protection (MPP) for control plan security, and Simple Network Management Protocol version3 (SNMPv3). Control plane protections integrated into line card Application-Specific Integrated Circuits (ASICs) include Generalized TTL Security Mechanism (GTSM), RFC 3682, and Dynamic Control Plane Protection (DCPP).

Availability—This supports rich availability features such as fault containment, fault tolerance, fast switchover, link aggregation, nonstop routing for ISIS, LDP and OSPF, and nonstop forwarding (NSF).

Enhanced core competencies:

IP fast convergence with Fast Reroute (FRR) support for Intermediate System-to-Intermediate System (IS-IS)

Path Computation Element (PCE) capability for traffic engineering

Memory Requirements


Caution If you remove the media in which the software image or configuration is stored, the router may become unstable and fail.

The minimum memory requirements for Cisco ASR 9000 Series Aggregation Services Router running Cisco IOS XR Software Release 4.2 consist of the following:

minimum 4-GB memory on the route switch processors (RSPs) [maximum is 8-GB]

minimum 2-GB compact flash on route switch processors (RSPs)

minimum 4-GB memory on the line cards (LCs)

These minimum memory requirements are met with the base board design.

RSP Memory Upgrade

This section describes the process to upgrade the Cisco ASR 9000 Series Aggregation Services Router running Cisco IOS XR Software Release 4.2 from a small memory model (ASR9k-RSP-4G) RSP card to a large memory model (ASR9k-RSP-8G) RSP card.

The upgrade sequence is as follows:


Step 1 Remove the standby small memory (ASR9k-RSP-4G) RSP card.

Step 2 Insert the large memory (ASR9k-RSP-8G) RSP card.

Step 3 Boot up the large memory (ASR9k-RSP-8G) RSP card so that it comes up as standby.

Step 4 Failover from the active small memory (ASR9k-RSP-4G) RSP card to the standby large memory (ASR9k-RSP-8G) RSP card.

Step 5 Remove the standby small memory (ASR9k-RSP-4G) RSP card.

Step 6 Insert the second large memory (ASR9k-RSP-8G) RSP card. Boot up this second large memory (ASR9k-RSP-8G) RSP card so that it comes up as standby.


RSP Memory Downgrade

This section describes the process to downgrade the Cisco ASR 9000 Series Aggregation Services Router running Cisco IOS XR Software Release 4.2 from a large memory model (ASR9k-RSP-8G) RSP card to a small memory model (ASR9k-RSP-4G) RSP card.


Caution Before attempting an RSP memory downgrade, measure the memory consumption of the current system configuration using the large memory model (ASR9k-RSP-8G) RSP card. You need to ensure that the Cisco ASR 9000 Series Aggregation Services Router running Cisco IOS XR Software Release 4.2 is still able to run the system configuration using the small memory model (ASR9k-RSP-4G) RSP card.

The RSP memory downgrade sequence is as follows:


Step 1 Verify that the memory consumption on the active large memory model (ASR9k-RSP-8G) RSP card can fit within the memory constraints of the small memory model (ASR9k-RSP-4G) RSP card.

Step 2 Remove the standby large memory model (ASR9k-RSP-8G) RSP card.

Step 3 Insert the small memory model (ASR9k-RSP-4G) RSP card. The system does not boot up the small memory model (ASR9k-RSP-4G) RSP card by default. Send user command to boot up the small memory model (ASR9k-RSP-4G) RSP card as standby.

Step 4 Failover from the active large memory model (ASR9k-RSP-8G) RSP card to the standby small memory model (ASR9k-RSP-4G) RSP card.

Step 5 Remove the standby large memory model (ASR9k-RSP-8G) RSP card.

Step 6 Insert the small memory model (ASR9k-RSP-4G) RSP card. Boot up this second small memory model (ASR9k-RSP-4G) RSP card as standby.

Note that error messages may display if features run without the appropriate licenses installed. For example, when creating or configuring VRF, if the A9K-IVRF-LIC license is not installed before creating a VRF, the following message displays:

 
   
RP/0/RSP0/CPU0:PE1-AS1#LC/0/0/CPU0:Dec 15 17:57:53.653 : rsi_agent[247]: 
%LICENSE-ASR9K_LICENSE-2-INFRA_VRF_NEEDED : 5 VRF(s) are configured without license 
A9K-iVRF-LIC in violation of the Software Right To Use Agreement. This feature may be 
disabled by the system without the appropriate license. Contact Cisco to purchase the 
license immediately to avoid potential service interruption.  
 
   

For Cisco license support, please contact your Cisco Sales Representative or Customer Service at 800- 553-NETS (6387) or 408-526-4000. For questions on the program other than ordering, please send e-mail to: cwm-license@cisco.com.

Cisco ASR 9000 Series Aggregration Services Router Right-To-Use (RTU) Licensing

Here are on-line locations of the Cisco ASR 9000 Series Aggregration Services Router Right-To-Use (RTU) licensing docs:

http://www.cisco.com/en/US/docs/routers/asr9000/hardware/Prodlicense/A9k-AIP-LIC-B.html

http://www.cisco.com/en/US/docs/routers/asr9000/hardware/Prodlicense/A9k-AIP-LIC-E.html


Note Layer 3 VPNs are only to be used after you have purchased a license. Cisco will enforce the RTU of L3VPNs in follow on releases. You should contact Cisco, or check the release notes for the follow on release before upgrading for directions on how to install the license as part of the upgrade - otherwise the L3VPN feature may be affected.


The activation of VRF capability still requires the use of the appropriate per line card license (A9K-IVRF-LIC / A9K-AIP-LIC-B / A9K-AIP-LIC-E). Please contact your sales representative for more details.

Other Firmware Support

To check the firmware code supported by the Cisco ASR 9000 Series Aggregation Services Router, run the show fpd package command in admin mode.


Note In upgrading from Release 3.7.3 or earlier releases, you may be expected to do a one-time FPD upgrade for any firmware images that may have changed since the last release. Refer to the documents at http://www.cisco.com/web/Cisco_IOS_XR_Software/index.html for upgrade instructions.


Check the firmware needed by running the show fpd package command in admin mode.

Features Introduced in Cisco IOS XR Software Release 4.2

The following sections contain information on new features and enhancements in Cisco IOS XR Software Release 4.2:

Software Features Introduced in Cisco IOS XR Software Release 4.2 for the Cisco ASR 9000 Series Router

Hardware Features Introduced in Cisco IOS XR Software Release 4.2 for the Cisco ASR 9000 Series Router

Software Features Introduced in Cisco IOS XR Software Release 4.2 for the Cisco ASR 9000 Series Router

The following new software features were introduced in Cisco IOS XR Software Release 4.2 on the Cisco ASR 9000 Series Router platform:

SNMP over IPv6—The Cisco IOS XR Software Release 4.2 supports Simple Network Management Protocol (SNMP) over IPv6 on the Cisco ASR 9000 Series Aggregation Services Router. The following SNMP commands are provided with IPv6 support in the Cisco IOS XR Software Release 4.2:

snmp-server host

snmp-server target-list

snmp-server vrf

snmp-server engineid remote

For more information about SNMP server commands, see the SNMP Server Commands on Cisco IOS XR Software section in Cisco IOS XR System Management Command Reference.

IEEE 1588 (Precision Time Protocol)—The Cisco IOS XR Software Release 4.2 provides support for IEEE 1588 Precision Time Protocol on the Cisco IOS XR ASR 9000 Series Aggregation Services Routers. IEEE 1588 standard defines a method for distributing time around a network, using the Precision Time Protocol (PTP) that allows precise synchronization of devices on a network. The protocol synchronizes real-time clocks in the nodes of a distributed system that communicate using a network to a common time based with nanosecond accuracy. This protocol consists of two parts:

The Port State Machine and Best Master Clock Algorithm, which provides a scheme for determining, which ports in the network should run as master that provides time to other clocks to the network, which as slave that receives time from other clocks in the network, and which should be passive (neither master or slave).

Mechanisms for slave ports to calculate the difference between the time of its own clock and the time of its master clock. PTP defines two methods to achieve this, the Delay Request-Response mechanism and the Peer Delay mechanism.

This feature requires RSP3 and Typhoon cards. The following interfaces are configured to run as PTP ports:

All line card IEEE 802.3 Ethernet interfaces.

DOT1Q VLAN interfaces and QinQ interfaces.

L2 Attachment Circuits.

PTP is supported over two different transport media - Ethernet and UDP over IPv4.

1-Port Channelized OC-3 ATM CEoP SPA — The physical layer interface for the 1-Port Channelized OC-3 Asynchronous Transfer Mode Circuit Emulation over Packets Shared Port Adapters (ATM CEoP SPA) is Optical Carrier-3 (OC-3). This SPA provides one 155.52 Mbps OC-3 network interface for all supported platforms. The single SPA port accepts an Small Form-Factor Pluggable (SFP) module with a duplex LC-type receptacle that allows connection to optical fibre. For more information about this SPA, see the Cisco ASR 9000 Series Aggregation Services Router SIP and SPA Hardware Installation Guide.

NAT44 on ISM—Cis co Carrier-Grade IPv6 (CGv6) solution is a complete suite of applications to help user transitioning from IPv4 to IPv6. NAT44 (Network Address Translation) is one of the applications available in the CGv6 suite and is supported from Release 4.2 onwards. NAT44 (Network Address Translation) is supported on ISM line cards on Cisco ASR 9000 Series Aggregation Services Routers starting from the Cisco IOS XR Software Release 4.2. NAT44 is a large Network Address Translation that is capable of providing private IPv4 to public IPv4 address translation in the order of millions of translations to support a large number of subscribers, and at least 10 Gbps of (inside-to-outside and outside-to-inside) I-MIX traffic per ISM card.

NAT44 on CGv6 offers a way for service provider subscribers and content providers to implement a seamless transition to IPv6. NAT44 on CGv6 employs a network address and port translation (NAPT) methods to aggregate many private IP addresses in to fewer public IPv4 addresses.

The following references can be used for information on CGV6 configuration and commands:

Cisco ASR 9000 Series Aggregation Services Router Carrier Grade IPv6 (CGv6) Configuration Guide, Release 4.2.0—Implementing the CGv6 on Cisco IOS XR Software section of this guide provides information about CGv6 configuration.

Cisco ASR 9000 Series Aggregation Services Router Carrier Grade IPv6 (CGv6) Command Reference, Release 4.2.0—CGv6 Commands on Cisco IOS XR Software section of this guide provides information about the commands used for the CGv6 implementation and operation.

IPv4/IPv6 VRF-aware ABF—The IPv4/IPv6 VRF-aware ABF feature supports next-hop VRF and IPv4/IPv6 address based on the access control entries (ACE) rule for packet forwarding. It supports up to three next-hops or default next-hops in IPv4/IPv6 ACE configuration each specifying optional VRF name and IPv4/IPv6 address. For more information about IPv4/IPv6 VRF-aware ABF feature, see the Implementing Access Lists and Prefix Lists module in the Cisco ASR 9000 Series Aggregation Services Router IP Address and Services Configuration Guide. For complete command reference of the access list commands, see the Access List Commands chapter in the Cisco ASR 9000 Series Aggregation Services Router IP Address and Services Command Reference.

IPv6 Lawful Intercept—An additional support to intercept IPv6 packets based on flow ID has been introduced on the Cisco ASR 9000 Aggregation Services Router to further extend filtration criteria for IPv6 packets. Based on the fields in the IPv6 header that comprises numerous fields defined in IPv6 Header Field Details table, all IPv6 packets are intercepted. The filtration criteria to intercept packets matching a particular flow ID is defined in the tap configuration file. The intercepted mapped flow IDs are sent to the next hop, specified in the MD (Mediation Device) configuration file and the intercepted packets are replicated and sent to the MD, from the line card. The ideal replicate rate on MSC-40 is 100 Mbps depending on packet size and features configured on the router.

BFD Multihop Global TTL Check—BFD (Bidirectional Forwarding Detection) provides low-overhead, short duration detection of failures in the path between adjacent forwarding engines. BFD Multihop is a BFD session between two addresses that are not on the same interface. BFD can have one global configurable minimum TTL value to drop packets in hardware. Using a peer-router TTL threshold, BFD packets can be sent with a TTL value of 255 and packets received with a TTL smaller than N are discarded. Although, this is a weak security, it is relatively simple to implement in the Network processor.

BFD Multihop support for BGP—The first application that makes use of BFD multihop will be BGP (Border Gateway Protocol). BFD for BGP can be enabled on a neighbor router and a neighbor router configuration is supported for BGP only. For more information about the configuration of BFD Multihop on a BGP, see the Configuring Bidirectional Forwarding Detection on the Cisco ASR 9000 Series Router Guide.

BFD Multihop support for IPv4—In a BFD Multihop session, BFD control packets on IPv4 are used to confirm the liveness of the remote peer. It also detects interruptions of the forwarding path between two BFD peers based on the detection time used for a BFD Multihop session. During the BFD session bring-up phase, the source IP address and destination IP address pair of an incoming packet along with its VRF context is used to identify a particular BFD Multihop session, until the discriminators of both BFD speakers are exchanged. This method is used for multihop sessions requested from routing protocols.

CEM (Circuit Emulation over Packet Switched Network over MPLS)—Circuit Emulation over Packet (CEoP) is a way to carry TDM circuits over packet switched network and is the imitation of a physical connection. CEoP replaces leased lines and legacy time-division multiplex (TDM) networks putting TDM bits into packets, encapsulates them into appropriate header and sends through public switched network (PSN). The Cisco IOS XR Release 4.2 supports CEM functionality only on the SPA, 1-port Channelized OC3 SPA [SPA-1xOC3-CE-ATM]. For more information about CEM, see the Configuring Circuit Emulation over Packet on the Cisco ASR 9000 Series Router/Cisco IOS XR Software chapter in Cisco ASR 9000 Series Interfaces and Hardware component Configuration Guide.

Link Bundling for POS Interfaces—Link Bundling is used to group multiple point-to-point links together into one logical link to provide higher bidirectional bandwidth, redundancy, and load balancing between two routers. The Cisco ASR 9000 Series Router supports bundling for POS interfaces on the ASR 9000 SIP-700 line card. The line card can physically accommodate up to 32 POS link bundles provided that all of them have the same speed.

A bundled POS interface can be created by configuring both the bundle and the member interfaces. For ethernet link bundling, links within a single bundle must be at the same speed. For POS link bundling, links within a single bundle can have mixed speed and bandwidth rate up to 4x among links is supported. POS link bundles does not support IPv6, LACP, ACL, VPLS and Multicast for Release 4.2. For more information about the POS link bundles, see the Configuring Link Bundling on the Cisco ASR 9000 Series Router Guide.

Unidirectional Link Detection Protocol (UDLD)—UDLD is a single-hop physical link protocol used to monitor an ethernet link, such as point-to-point and shared media links. It detects link problems that are not detected at the physical layer and is used especially in situations, where there can be a mismatch between the transmitting and receiving connections of a port during possible wiring errors, when using unbundled fiber links. UDLD works by exchanging protocol packets between the neighboring devices based on the condition that both the devices on the link must support UDLD and have it enabled on respective ports.

For more information about UDLD operation, see the Cisco ASR 9000 Series Aggregation Services Router Interface and Hardware Component Configuration Guide.

IPv4 Generic Routing Encapsulation (GRE)—GRE is a tunneling protocol used to encapsulate many types of packets to enable data transmission using a tunnel. For more information about GRE, see the Cisco ASR 9000 Series Aggregation Services Router MPLS Layer 3 VPN Configuration Guide

Local Connect Redundancy—Local Connect Redundancy (LCR) addresses the local switching limitation of Multi-Chassis Link Aggregation (MC-LAG) implementation in Cisco IOS XR Software Release 4.0. The LCS solution provides Loose Coupling between the DHDs. If one of the DHDs is switched and the second DHD is not be switched, yet the loop is closed by providing a path for traffic between the two PoAs. This approach is used to protect the XC with a backup interface going to the other PoA. The backup interface will become active in case of failures.

MPLS Transport Profile—Pseudowires (PWs) use MPLS transport profile (MPLS-TP) tunnels as a transport mechanism within the MPLS-TP environment to provide the transport network service layer for the IP and MPLS traffic to traverse over it. MPLS-TP tunnels provide Transport networks functionality through statistically provisioned bidirectional label switched paths (LSPs). MPLS-TP supports static-static, static-dynamic, and dynamic-static multisegment pseudowires.

For more information about MPLS-TP, see the Cisco ASR 9000 Series Aggregation Services Router L2VPN and Ethernet Services Guide.

QoS Policy Propagation using Border Gateway Protocol (QPPB)—Quality-of-Service Policy Propagation Using Border Gateway Protocol (QPPB) helps to classify packets by QoS Group ID, based on Access control lists (ACLs), Border Gateway Protocol (BGP) community lists, BGP autonomous system (AS) paths, Source Prefix address, or Destination Prefix address. After packet classification, other QoS features such as policing and weighted random early detection (WRED) can be used to specify and enforce policies to fit a specific business model. QPPB also allows the user to map BGP prefixes and attributes to Cisco Express Forwarding (CEF) parameters that can be used to enforce traffic policing.

QoS for POS link bundling—For POS link bundles, bandwidth is used in terms of percentage for policers and output queues. The queue limit for output queues is based on time. As queuing is not supported for input QoS, bandwidth is used for policer only. With input QoS configured, the aggregate bundle bandwidth for the affected line card changes, as a member link is added or removed from a bundle. One input Qos policy instance is assigned for each SIP 700 line card in POS link bundle. When a member link is added to a bundle with output QoS configured, the policy map of the bundle is applied to the member link.

QoS for BNG—The Broadband Network Gateway (BNG) provides Session Aware Ethernet services for PPPoE subscribers. Quality-of-Service for BNG requires new QoS parameters to be included and existing parameters to be changed in a broadband subscriber management, since quick activation, deactivation and modifications of QoS policies are necessary.

For more information about QoS for BNG, see the Configuring QoS for Broadband Network Gateways on Cisco ASR 9000 Series Routers Guide.

ACL Based Forwarding—ACL Based Forwarding (ABF) is used by specifying the next-hop address in ACL configurations, so that the configured next-hop address from ACL is used for forwarding packet towards its destination instead of routing packet-based destination address lookup. ABF helps to choose service from multiple providers for broadcast TV over IP, IP telephony, data, and so on. Internet service providers can divert user traffic to various content provides through ABF functionality.

Selective VRF (Virtual Routing and Forwarding) Download—SVD is an architectural solution to alleviate scalability and convergence problems with L3VPN technologies. This solution is sued to download only those prefixes and lables to a line card that are actively required to forward traffic through that line card. SVD is enabled by default. The solution tries to optimize the table and route download to cards by classifying line cards by SVD card role and routes by SVD route type. For more information about SVD, see the Selective Virtual Routing and Forwarding Table Download: A solution to increase Layer3 VPN scale white paper at http://www.cisco.com/en/US/technologies/collateral/tk648/tk365/white_paper_c11-681649.html

Video Monitoring Unicast—Video Monitoring, which is implemented on the routers, improves video quality and QoE, enabling network operators to measure and track video transport performance on a per-flow basis. Video Monitoring monitors the flows with unicast destination addresses. Video Monitoring support for unicast flows provides backward compatibility to Trident LC and is also available on Typhoon LC. For more information about the Video Monitoring feature, see the Cisco ASR 9000 Series Aggregation Services Router IP Addresses and Services Configuration Guide.

BNG—Broadband Network Gateway (BNG) has a range of capabilities to improve the service provider's ability to control a subscriber's services and to simplify overall network operations. The BNG features provide subscriber management at a logical aggregation point in the network. The service provider can control the user experience through identification, address assignment, authentication, authorization, accounting, and various other features such as security, QoS, and subscriber forwarding. For more information about BNG and its configuration, see the Cisco ASR 9000 Broadband Network Gateway Configuration Guide.

High Availability for Lawful Intercept—The high availability for lawful intercept is a feature enabled by default from Release 4.2 onwards. It provides operational continuity of the TAP flows and provisioned MD (Mediation Device) tables to reduce loss of information due to route processor fail over (RPFO).

When RPFO is detected, MDs are required to re-provision all the rows related to CISCO-TAP2-MIB, CISCO-IP-TAP-MIB and CISCO-USER-CONNECTION-TAP-MIB, to synchronize database view across RP and MD. The replay timer, an internal timeout is used to re-provision TAP entries smoothly while maintaining existing TAP flows. For more information about high availability for lawful intercept, see the Cisco ASR 9000 Series Aggregation Services Router System Security Configuration Guide.

CISCO-IP-STAT-MIB—The CISCO-IP-STAT-MIB incorporates objects to provide support for the Cisco IP statistics as implemented in command interfaces. cipPrecendenceTable, cipMacTable, cipMacFreeTable, cipPrecedenceXTable, cipMacXTable are the tables available in CISCO-IP-STAT-MIB. For more information about the tables, see the Cisco ASR 9000 Series Aggregation Services Routers MIB Specifications Guide.

IF-MIB Congestion Control Support—A packet from ingress interface traverses through various internal queues before reaching the egress interface. Packets can be dropped when any of these queues cannot hold them, either due to the full queue or based on some policies or priorities. The respective queue or device drivers like ASIC drivers, interface drivers, platform manager, QoS EA, etc. can track the drop of the packets.

CISCO-IF-EXTENSION-MIB consists of two objects, cieIfInOctetRate and cieIfOutOctetRate for reporting number of bytes of data transferred from or to the interface within 5 minutes. The other two objects, cieIfInputQueueDrops and cieIfOutputQueueDrops are used for reporting packet drops in queues available through Stats Infrastructure. While configuring an interface for congestion control, a callback is registered with interface manager to get the bandwidth change and also notified to update rising threshold or falling threshold. All the interface types supported for packet loss configuration are also applicable to congestion control configurations.

CISCO-USER-CONNECTION-TAP-MIB—The ASR 9000 Series Aggregation Services Router supports CISCO-USER-CONNECTION-TAP-MIB. This MIB provides the mechanism to provision for lawful interception of Broadband Network Gateway (BNG) subscribers. For more information about this MIB, see the Cisco ASR 9000 Broadband Network Gateway Configuration Guide.

CISCO-SELECTIVE-VRF-DOWNLOAD-MIB—This MIBmodule defines objects describing selective VRF download. To know more about the selective VRF download (SVD) feature, see the feature description in this section. For more information about CISCO-SELECTIVE-VRF-DOWNLOAD-MIB, see the Cisco ASR 9000 Series Aggregation Services Routers MIB Specifications Guide.

IF-MIB Congestion Control Trap—When congestion control goes above upper threshold, a SNMP trap is generated to indicate that an event is set. When congestion control goes below lower threshold, another SNMP trap is generated to indicate that an event is cleared. mteTriggerThreshold table contains the details on threshold values for congestion control. The following provides sample trap information:

Received SNMPv2c Trap:
Community: public
From: 12.25.20.9
sysUpTimeInstance = 618943
snmpTrapOID.0 = mteTriggerFalling
ifType.87 = hdlc(118)
ifName.87 = POS0/2/0/0
mteHotValue.0 = 3500
mteHotOID.0 = [cieIfInOctetRate.87 | cieIfInputQueueDrops.87]
mteHotContextName.0 = 
mteHotTargetName.0 = 
mteHotTrigger.0 = POS0_2_0_0-ingress
 
   
Received SNMPv2c Trap:

From: 12.25.20.9
sysUpTimeInstance = 619943
snmpTrapOID.0 = mteTriggerRising
ifType.87 = hdlc(118)

mteHotContextName.0 = 
mteHotTargetName.0 = 
mteHotTrigger.0 = POS0_2_0_0-egress
 
   

Multiple Group Optimization (MGO) for HSRP—By running the Hot Standby Router Protocol (HSRP) control traffic for just one of the sessions, MGO reduces control traffic in a deployment consisting of many subinterfaces with identical redundancy requirements. All other sessions that become slaves of this session inherit their state from this session. For more information on MGO, see the Cisco ASR 9000 Series Aggregation Services Router IP Addresses and Services Configuration Guide.

Redundancy Manageability Improvements—This feature supports configuration, control and monitoring of redundancy protection for various kinds of components on Cisco managed devices. It is a generic approach to handle basic redundancy control and monitoring for many types of redundant member components and redundancy architectures as long as there is an Entity MIB entPhysicalIntex and entPhysicalVendorType assigned to each member component. For more information about this feature, see the Cisco ASR 9000 Series Aggregation Services Routers MIB Specifications Guide.

Security Hardening—In Cisco IOS XR LPTS, as part of for-us packet delivery process, the rate at which packets are delivered are selectively monitored to avoid overwhelming the CPU. LPTS filters and polices the packets based on the defined flow-type rate in hardware before punting to the software. Today, some of the control protocols have a configured peer or source interface in some way, but the protocol (application) and/or LPTS ignores the peer configuration or has a single policer rate for all known and unknown (default) connections. This restricts the user's ability to police the rates for known peers differently than for unknown peers.

Cisco IOS XR security system needs a granular protocol traffic classification based on the configured peers and ingress interfaces. To classify and distinguish the traffic accurately, the protocol or application needs to have new flow-types and policer rates in hardware. New flow-types such as DNS, RADIUS, TACACS, NTP KNOWN, RSVP KNOWN and PIM MULTICAST KNOWN are added to the configuration. The user gets the new flow types by running the following command:

show lpts pifib hardware police location 0/3/CPU0

79 (null) 101 0/0
 
   

For more information about LPTS commands, see the Cisco ASR 9000 Series Aggregation Services Router IP Addresses and Services Command Reference.

SNMP context/view improvements—The CISCO-CONTEXT-MAPPING-MIB provides an option to associate an SNMP context to a feature package group. This MIB allows manageability of license MIB objects specific to a feature package group. For more information about this feature, see the Cisco ASR 9000 Series Aggregation Services Routers MIB Specifications Guide.

VRF-aware IF-MIB—The IF-MIB describes the attributes of physical and logical interface. This MIB is made VRF-aware to provide access to information on selected interfaces stored in IF-MIB table to a user. VRF-aware IF-MIB makes management of IF-MIB table for VRF based network more secure. The ifTable and ifXTable are VRF-aware tables.

BGP Multi-Instance/Multi-AS— BGP (Border Gateway Protocol) Multi-Instance/Multi-AS feature allows BPM to directly interact with BGP speakers and sends configuration information using the AIPC channels. The Async IPC (AIPC) is a point-to-point communication channel that can be used to read and write bi-directionally. The Cisco IOS XR Software Release 4.2 supports multiple BGP instances running:

Different address families within an unit under test(UUT).

Different ASes within an UUT with each AS running different address families.

VPNVX unicast address family with mutually exclusive VRFs with an UUT.

The constraint is that each BGP speaker process must run mutually exclusive address family or VRFs due to the underlying shared RIB/FIB infrastructure. The Cisco IOS XR Software Release 4.2 also facilitates migration of configuration republishing mechanism between BPM process and BGP speaker process(es) from sysdb to Async IPC for filtered configuration publication for each BGP speaker process as well as for reducing load to sysdb.

OSPFv2 Per-Prefix LFA IPFRR & SRLG support—Per-prefix LFA computation is used to find the backup path for each individual path to the prefix that is subject to the computation based on the user configuration. The computation finds out a neighbor to which traffic for prefix can be sent in case of a primary link failure. This guarantees that the traffic is not sent back to the calculation node. Users can limit the amount of prefixes, for which per-prefix LFA computation is done, thus by associating the minimum prefix priority with the per-prefix LFA computation. Per-prefix LFA considers the local SRLG values during the backup computation. SRLG integration with per-prefix LFA is done through the tiebreaker approach, where SRLG disjoint is used as one of the tiebreakers.

OSPFv3 Non-Stop Routing (NSR) support—The Cisco IOS XR Software Release 4.2 supports NSR functionality for OSPFv3 processes. When NSR is enabled (disabled by default), OSPFv3 processes on the active RP, synchronizes all necessary data, and states with the OSPFv3 process on the standby RP. During the switchover, OSPFv3 processes on the newly active RP has all the necessary data and states to continue running, and does not require any help from its neighbors.

Route Consistency Checker (RCC) and Label Consistency Checker (LCC)—RCC and LCC are used to verify consistency periodically in the background, as well as on-demand from the CLI, between control plane and data plane route and label programming in a Cisco IOS XR Software. Any detected inconsistencies are re-verified to ensure no false positives, and the detection mechanism uses an adaptive algorithm to ensure that route and label convergence are not affected in any way. For more information on how to use the RCC and LCC, see the Cisco ASR 9000 Series Aggregation Services Router Routing Configuration Guide.

Hierarchical RPL—Hierarchical Routing Policy Language (RPL) enables apply condition policies to specify a route policy in the if statement of another route policy. It also enables route policies to be applied for configurations based on hierarchical policies. Cisco IOS XR RPL supports apply condition policies that can be used with various types of Boolean operators along with various other matching statements. Apply conditions can also be used with parameters and are supported on all attach points and on all clients. Hierarchical apply conditions can be used without any constraints on cascaded level.

System-wide Route and Label Prioritization—System-wide Route and Label Prioritization feature provides faster and more consistent Interior Gateway Protocol (IGP) convergence due to router or network events. For more information on how to prioritize and download the critical routes and labels, see the Cisco ASR 9000 Series Aggregation Services Router Routing Configuration Guide.

MPLS Traffic Engineering (TE) Soft Preemption—Multiprotocol Label Switching (MPLS) TE Soft Preemption is an extension to the Resource ReSerVation Protocol Traffic Engineering (RSVP-TE) protocol to minimize or eliminate the traffic disruption over the preempted Label Switched Paths (LSPs). For more information on how to achieve zero traffic loss, see the Cisco ASR 9000 Series Aggregation Services Router MPLS Configuration Guide.

MPLS Traffic Engineering (TE) Path-Option Attributes—MPLS TE path option attributes are configurable through a template configuration. This template named attribute-set, is configured globally in the MPLS TE mode. For more information on how to implement path option attributes, see the Cisco ASR 9000 Series Aggregation Services Router MPLS Configuration Guide.

Downstream on Demand for BGP Labels—This feature adds support for the downstream-on-demand mode where the label is not advertised to a peer unless the peer explicitly requests it. At the same time, because the peer does not automatically advertise labels, a label request must be sent whenever the next-hop points to a peer to which no remote label has been assigned.

For more information about this feature, refer to the Downstream on Demand section of the Cisco ASR 9000 Series Aggregation Services Router MPLS Configuration Guide.

Any Transport over MPLS (AToM): HDLC over MPLS (HDLCoMPLS)—The attachment circuit (AC) is a main interface configured with HDLC encapsulation. Packets to or from the AC are transported using an AToM pseudowire (PW) of VC type 0x6 to or from the other provider edge (PE) router over te MPLS core network.

With HDLC over MPLS, the entire HDLC packet is transported. The ingress PE router removes only the HDLC flags and FCS bits.

Any Transport over MPLS (AToM): PPP over MPLS (PPPoMPLS)—The AC is a main interface configured with PPP encapsulation. Packets to or from the AC are transported through an AToM PW of VC type 0x7 to or from the other PE routers over the MPLS core network.

With PPP over MPLS, the ingress PE router removes the flags, address, control field, and the FCS bits.

Load Balancing on Link Bundles—The Cisco ASR 9000 Series Aggregation Services Router supports load balancing for all links in a bundle using Layer 2, Layer 3, and Layer 4 routing information. For more information about load balancing on link bundles, see the Configuring Link Bundling on the Cisco ASR 9000 Series Router section of the Cisco ASR 9000 Series Aggregation Services Router Interface and Hardware Component Configuration Guide.

Dynamic Load Balancing for LAG—Beginning in Cisco IOS XR Release 4.0.1, the Cisco ASR 9000 Series Aggregation Services Router supports a method of dynamic load balancing among link aggregation (LAG) members. With dynamic load balancing, the hash algorithms for link selection include up to a maximum of 64 links, and are based on the current number of active members in the bundle.

Layer 3 Load Balancing on Link Bundles—Layer 3 load balancing for link bundles is done when outgoing interfaces are either bundles or bundle subinterfaces. 5-tuple hashing is used for load balancing among bundle member links, using the following parameters:

IP source address

IP destination address

Router ID

Layer 4 source port

Layer 4 destination port


Note In Cisco IOS XR Release 4.0.1, the hw-module load-balance bundle l2-service l3-params command is replaced by the load-balancing flow command in L2VPN configuration mode.


BFD Per Member Link—Beginning in Cisco IOS XR Release 4.0.1, the BFD feature supports BFD sessions on individual physical bundle member links to monitor Layer 3 connectivity on those links, rather than just at a single bundle member as in prior releases on the Cisco ASR 9000 Series Router.

When you run BFD on link bundles, you can run an independent BFD session on each underlying physical interface that is part of that bundle.

When BFD is running on a link bundle member, the following layers of connectivity are effectively tested as part of the interface state monitoring for BFD:

Layer 1 physical state

Layer 2 Link Access Control Protocol (LACP) state

Layer 3 BFD state

The BFD agent on each bundle member link monitors state changes on the link. BFD agents for sessions running on bundle member links communicate with a bundle manager. The bundle manager determines the state of member links and the overall availability of the bundle. The state of the member links contributes to the overall state of the bundle based on the threshold of minimum active links or minimum active bandwidth that is configured for that bundle.

BFD Echo Latency Detection—Beginning in Cisco IOS XR 4.0.1, you can configure BFD sessions on non-bundle interfaces to bring down a BFD session when it exceeds the configured echo latency tolerance.

BFD Echo Startup Validation—Beginning in Cisco IOS XR Release 4.0.1, you can verify that the echo packet path is working and within configured latency thresholds before starting a BFD session on non-bundle interfaces.

For more information about BFD Per Member Link, refer to the Cisco ASR 9000 Series Aggregation Services Router Interface and Hardware Component Configuration Guide.

PVST+ Gateway—Per-Vlan STP (PVST) is a mechanism for creating multiple spanning trees. Using PVST, a separate spanning tree is created for each VLAN.

For more information about this feature, refer to the Implementing Multiple Spanning Tree Protocol section of the Cisco ASR 9000 Series Aggregation Services Router L2VPN and Ethernet Services Configuration Guide.

RSVP signaling on top of IPv6 bundle interfaces

TE and FRR on top of IPv6 bundle interfaces

GRE, L2TPv3 tunnels on top of IPv6 bundle interfaces

IPSEC tunnels over IPv6 bundle interfaces

Limitations:

User shall be able to configurable thresholds for the number of component links that need to be up and active for a link bundle to be up and active

Support up to 4000 (4k) Bundle VLANs in total.

L2VPN service over IPv6 bundled interfaces

MVPN Service over IPv6 bundled interfaces

On the Cisco ASR 9000 Series Aggregation Services Router platform, this feature is available for all line cards

Ipv6 on bundles is not supported on the SIP-700 on the Cisco ASR 9000 Series Aggregation Services Router platform

IPv6 ACLs on bundles is supported from release 3.9.2 onwards

IPv6 multicast is not supported on bundle interfaces/normal interfaces in 3.9.2

More information about link bundling configuration and monitoring can be found in the following Command Reference Guides, Cisco ASR 9000 Series Aggregation Services Router Interface and Hardware Component Command Reference and Cisco ASR 9000 Series Aggregation Services Router L2VPN and Ethernet Services Command Reference, online.

ACL Based Forwarding (ABF)

Cisco IOS XR Software Release 3.9.2 introduces support on the Cisco ASR 9000 Series Aggregation Services Router platform for packet forwarding and routing according to customer defined policies.

An access control list (ACL) consists of one or more access control entries (ACE) that collectively define the network traffic profile. This profile can then be referenced by Cisco IOS XR Software features such as traffic filtering, route filtering, QoS classification, and access control. Each ACL includes an action element (permit or deny) and a filter element based on criteria such as source address, destination address, protocol, and protocol-specific parameters.

Prefix lists are used in route maps and route filtering operations and can be used as an alternative to access lists in many Border Gateway Protocol (BGP) route filtering commands. A prefix is a portion of an IP address, starting from the far left bit of the far left octet. By specifying exactly how many bits of an address belong to a prefix, you can then use prefixes to aggregate addresses and perform a function on them, such as redistribution (filter routing updates).

Hardware Limitations:

Support for ABF is only for IPv4 and Ethernet line cards. IPv6 and other interfaces are not supported

ABF is an ingress line card feature and the egress line card must be ABF aware.

SIP-700 is not ABF aware and hence drops ABF packets.

Restrictions:

The following nexthop configurations are not supported:

Attaching ACL having a nexthop option in the egress direction.

Modifying an ACL attached in the egress direction having nexthop.

deny ACE with nexthop.

The following interfaces are not supported: loopback, interflex, and L2.

The ABF feature configuration on A9K-SIP-700 is not supported.

ABF nexthop packets received by A9K-SIP-700 are dropped.


Note There is one exception to this. In case of IP to TAG, the label is imposed by the ingress LC (based on ABF nexthop), and the packet crosses the fabric as a tag packet. These packets are handled by A9K-SIP-700 without any issue.


Packets punted in the ingress direction from the NPU to the LC CPU are not subjected to ABF treatment due to lack of ABF support in the slow path.


Note For example, IP Options packets are not subjected to ABF. The packet is forwarded without ABF.


Packets punted in the egress direction from the NPU to the LC CPU other than in order to glean adjacency are not subjected to ABF treatment due to the lack of ABF support in the slow path.


Note IP packet(s) needing fragmentation are not subjected to ABF. The packet is forwarded in the traditional way. Fragmented packets received are handled by ABF.


nexthop in VRF is not supported. nexthop is looked at in the global table only.

Generic Routing Encapsulation (GRE)

Cisco IOS XR Software Release 3.9.2 introduces support on the Cisco ASR 9000 Series Aggregation Services Router platform for the GRE tunneling protocol. GRE is a simple, generic way to transport packets of one protocol over another protocol by means of encapsulation. The GRE tunneling protocol enables:

High Assurance Internet Protocol Encryptor (HAIPE) devices for encryption over the public Internet and non secure connections.

Service providers (that do not run MPLS in their core network) to provide VPN services along with the security services.

For more information on this feature, refer to the Cisco ASR 9000 Series Aggregation Services Router Interface and Hardware Component Configuration Guide and the Cisco ASR 9000 Series Aggregation Services Router Interface and Hardware Component Command Reference online.

Hardware Limitations:

Support for GRE is only for the Ethernet line card.

SIP-700 is not GRE aware and will drop GRE packets.

Restrictions:

The GRE feature has the following restrictions.

A maximum of 500 GRE tunnels can be configured per system.

GRE is limited to tunneling of unicast IPv4 data packets.

Packets received with nested and concatenated GRE headers are dropped.

Transport header support is limited to IPv4

Path MTU discovery is not supported over GRE tunnel interfaces. When size of the packet going over GRE tunnel interface exceeds the tunnel MTU, the ucode will punt the packet to the slow path for best effort fragmentation. Since punted packets are policed, this doesn't provide real fragmentation support. If the decap router receives a fragmented GRE packet, the fragments will also be punted to the slow path for best-effort reassembly. The user is responsible for making sure the MTUs configured along the tunnel path are large enough to guarantee the GRE packet will not be fragmented between tunnel source and destination routers.

No Layer 3 features (like QoS, ACL and netflow) are supported over GRE tunnel interfaces. Features configured on the underlying physical interface will be applied.

No support for optional checksum as defined in RFC2784.

No support for key, and sequence number fields as defined in RFC2890.

[no] transport-mode {wan | otn}
 
   
 
   
RP/0/RSP0/CPU0:ROSH10(config-if)#transport-mode  wan
RP/0/RSP0/CPU0:ROSH10(config-if)#transport-mode  otn bit-transparent {opu1e | ouu2e}
 
   

There are two loopback modes available under IPoDWDM:

RP/0/RSP0/CPU0:ROSH10(config)#controller dwdm 0/2/0/0 
RP/0/RSP0/CPU0:ROSH10(config-dwdm)#loopback ?
  internal  Select internal loopback mode
  line      Select line loopback mode
 
   

There are three types of admin states: in-service, maintenance, and out-of-service. Set the admin-state to out-of-service before provisioning any command under controller dwdm mode.

RP/0/RSP0/CPU0:ROSH10(config)#controller dwdm 0/2/0/0 
RP/0/RSP0/CPU0:ROSH10(config-dwdm)#admin-state ?
  in-service      change the admin-state to In-service (IS)
  maintenance     change the admin-state to Out-of-service-Maintenance (OOS-MT)
  out-of-service  change the admin-state to Out-of-service (OOS)
 
   

Here are the show controllers commands introduced to support the three states (lan, wanphy and dwdm):

RP/0/RSP0/CPU0:ROSH10#sh controllers tenGigE 0/2/0/0 ?

MR-APS

SONET, T1

Frequency Synchronization

IPv4 Netflow

QoS Features

Cisco IOS XR Software Release 3.9.0 added support on the Cisco ASR 9000 Series Aggregation Services Router with the SIP-700 and SPA-2XCHOC12/DS0 for the following QoS features:

Support for IPv4 payload on Serial (PPP encapsulation), MLPPP, and MCMP interfaces. Support for LFI traffic on MLPPP or MCMP bundles.

Support for classification based on DSCP, precedence, protocol, qos-group (egress only), discard-class (egress only), and access-lists.

Support for marking, policing, and priority (see Fabric QoS section) in the ingress direction.

Support for marking, policing, and all queueing actions (bandwidth, bandwidth-remaining, shaping, queue-limit, priority levels 1 and 2, and random-detect) in the egress direction.

On the SIP-700 and SPA-2XCHOC12/DS0 only a 2-parameter scheduler is supported i.e. either bandwidth or bandwidth-remaining can be used in the same policy, but not both.

Note that traffic shaping on an input interface is not supported on the SIP-700.

Two levels of hierarchy supported, with only class-default permitted in the parent policy-map.

Fabric QoS configured using the priority action in the ingress direction.

Support for re-programming the QoS policy in response to underlying link bandwidth change on multi-link interfaces. There is no support for in place QoS policy modification on the SIP-700.

Support for the "encap-sequence" action to set the traffic class for traffic on multi-class MLPPP interfaces in the egress direction.

The "set cos" command on the egress of a Layer 3 interface is valid and supported. The "set cos" command on the ingress of a Layer 3 interface is rejected when performed on a subinterface. The "set cos" command on the ingress of a Layer 3 interface is ignored on a main interface.

Y.1731 Performance Monitoring - Delay & Delay Variance

Cisco IOS XR Software Release 3.9.0 added support on the Cisco ASR 9000 Series Router for Y.1731 PM, which initially supports 2-way scheduled delay and delay variance measurements.

IP FRR

Cisco IOS XR Software Release 3.9.0 added support on the Cisco ASR 9000 Series Aggregation Services Router for IPFRR (IP Fast ReRoute), a set of technologies used in order to rapidly converge traffic flows around link and/or node failures. Only MLPPP encapsulation channels on the OC-12 SONET interface can be protected by IP-FRR in Cisco IOS XR Software Release 4.2.

L2 Multicast Limit

Cisco IOS XR Software Release 3.9.0 added support on the Cisco ASR 9000 Series Aggregation Services Router for the Layer 2 Multicast Limit feature, which supports IGMP Snooping based limits for both the maximum number of allowed multicast channels per subscriber and the maximum bandwidth available for multicast per subscriber.

Traffic Mirroring

Cisco IOS XR Software Release 3.9.0 added support on the Cisco ASR 9000 Series Aggregation Services Router for Local Traffic Mirroring (EFP to EFP) and also the option of appending a VLAN tag on the destination port for transport across an Ethernet network. Traffic Mirroring copies traffic from one or more Layer 2 interfaces or sub-interfaces, including Layer 2 link bundle interfaces/sub-interfaces, and sends the copied traffic to one or more destinations for analysis by a network analyzer or other monitoring device.

On a switch, unicast traffic from A to B is only forwarded to the B port. Therefore, the network analyzer does not see this traffic. When the Traffic Mirroring feature is enabled, the network analyzer is attached to a port that is configured to receive a copy of every packet that host A sends. This port is called a traffic mirroring port.

Currently, the Cisco ASR 9000 Series Aggregation Services Router only supports Local SPAN and R-SPAN.

A maximum of 8 monitor sessions, and 800 source ports are supported.

You can configure 800 source ports on a single monitor session or configure an aggregate total of 800 source ports on up to 8 different monitor sessions.

The following SPAN types are not supported:

ER-SPAN (Encapsulated Remote Switched Port Analyzer)

Traffic is mirrored to a remote site via a GRE tunnel.

Pseudowire SPAN (PW-SPAN).

Traffic is mirrored to a remote site via an MPLS pseudowire, instead of using a standard destination interface. (Plan to be supported in 4.0.1 release.)

VLAN-based SPAN.

In this case, the source for the mirrored traffic is not simply a set of interfaces, but is a full bridge-domain.

Filter-SPAN (F-SPAN)

In this case, flow and ACL are applied in mirroring the traffic.

Cisco recommends not mirroring more 15% of total transit traffic. On TenGigE or bundle interfaces there is a limit of 1.5G on each ingress and egress traffic port to be mirrored.

SPAN Configurations:

To create a "monitor-session" in global config:

-monitor-session <name>

- destination interface <dst_interface>

To attach a source port in local-plane config:

-interface <src-interface> l2transport

- monitor-session <name> [direction {rx_only | tx_only]

SPAN Configuration Samples:

SPAN with Physical Interfaces (Local SPAN)

The following example shows a basic configuration for SPAN with physical interfaces. When traffic flows over the point to point cross connect between gig0/2/0/19 and gig0/2/0/11, packets received and transmitted on gig0/2/0/19 will also get mirrored to gig0/2/0/15.

Video Monitoring

Cisco IOS XR Software Release 3.9.0 added support on the Cisco ASR 9000 Series Aggregation Services Router for the Video Monitor application, used to monitor video flows, detect quality degradation, report metrics and raise alarms.

LAG integration with H-QOS

Cisco IOS XR Software Release 3.9.0 added support on the Cisco ASR 9000 Series Aggregation Services Router for extending Hierarchical QoS (H-QoS) support to link aggregation bundles. Shared Policy Instances (SPI) allow for QoS policy shared across multiple sub-interfaces.

EFP Based Load Balancing

Cisco IOS XR Software Release 3.9.0 added support on the Cisco ASR 9000 Series Aggregation Services Router for EFP based load balancing, which provides a way to carry all the traffic of a specific EFP over a single physical member link.

Ethernet Connectivity Fault Management (E-CFM) with Ethernet Wire Service (EWS)

Cisco IOS XR Software Release 3.9.0 added support on the Cisco ASR 9000 Series Aggregation Services Router for Ethernet Connectivity Fault Management (E-CFM), a subset of EOAM that provides a number of protocols and procedures that allow discovery and verification of the path through 802.1 bridges and LANs. Note that CFM 100 ms CCMs and CFM Exploratory Linktrace were introduced on the Cisco ASR 9000 Series Aggregation Services Router with Cisco IOS XR Software Release 3.7.2.

BGP PIC Edge for IP/MPLS

Cisco IOS XR Software Release 3.9.0 added support on the Cisco ASR 9000 Series Aggregation Services Router for BGP PIC Edge for IP/MPLS, which provides sub-second convergence for IP and MPLS-VPN.

MPLS TE Path Protection

Cisco IOS XR Software Release 3.9.0 added support on the Cisco ASR 9000 Series Aggregation Services Router for MPLS TE path protection, which provides a backup tunnel between the MPLS/TE head-end and the tail router and added to Cisco's MPLS/TE suite of bandwidth protection features, which also include node protection and link protection.

Image Refresh using Compact Flash

Cisco IOS XR Software Release 3.9.0 added support on the Cisco ASR 9000 Series Aggregation Services Router for performing an image refresh using compact flash.

Features Introduced in Cisco IOS XR Software Release 3.7.3

The following features introduced in Cisco IOS XR Software Release 3.7.3 are supported on the Cisco ASR 9000 Series Aggregation Services Router platform:

MSTAG Enhancements

Cisco IOS XR Software Release 3.7.3 added support on the Cisco ASR 9000 Series Aggregation Services Router for multiple spanning tree access gateway (MSTAG) topology control.

MSTP Enhancements

Cisco IOS XR Software Release 3.7.3 added support on the Cisco ASR 9000 Series Aggregation Services Router for the following features added to MSTP:

PortFast—allows a port to be marked as an edge port that does not participate in the spanning tree.

BPDUGuard—protects PortFast ports from misconfigurations by error-disabling them if they receive a BPDU.

UplinkFast—allows a RootPort to transition straight to forwarding, if there are no other active RootPorts on the box.

BackboneFast—allows for accelerated recovery from indirect link failures.

RootGuard—prevents a port from becoming the RootPort.

MSTAG support on physical and bundle Ethernet interfaces.

EFP Egress Filtering on the Cisco ASR 9000 Series Router

Cisco IOS XR Software Release 3.7.3 introduced EFP Egress Filtering on the Cisco ASR 9000 Series Router.

For more information on configuring the EFP Egress Filtering feature including the associated EFP Egress Filtering commands on the Cisco ASR 9000 Series Aggregration Services Router router, refer to the Egress EFP Filtering on the Cisco ASR 9000 Series Router feature module.

Flood Optimization

In prior releases the Cisco ASR 9000 Series Aggregation Services Router acting as a bridge flooded broadcast and unknown unicast traffic to all the forwarding engines on all the line cards.

In Cisco IOS XR Software Release 3.7.2 if a pseudo wire is configured in a bridge domain all broadcast and unknown unicast traffic is flooded to all line cards in the system in order to attain fast convergence. With Cisco IOS XR Software Release 3.7.3 the flood optimization feature changes this default behavior. FGID will get programmed based on the primary paths on which the pseudo wire is going out and traffic will get flooded only to the line cards on which the pseudo wire resides. This mode is called Bandwidth Optimization mode.

But if a Fast ReRoute event occurs when fast convergence is set up it will take a longer time to complete the reroute as more hardware programming such as adding bridge ports etc. needs to be done. So for customers who are sensitive to this increased delay a command called flood mode convergence-optimized is provided in Cisco IOS XR Software Release 3.7.3. Use this flood mode convergence-optimized command to switch back to the convergence optimized mode where traffic gets flooded to all the line cards.

With this flood mode convergence-optimized command users are able to turn on/off the bandwidth optimized mode.

For more information on the flooding disable command and other Layer 2 VPLS commands on the Cisco ASR 9000 Series Aggregration Services Router router, refer to the Point to Point Layer 2 Services Commands section in the Cisco ASR 9000 Series Aggregation Services Router L2VPN and Ethernet Services Command Reference here:

http://www.cisco.com/en/US/partner/docs/routers/asr9000/software/asr9k_r4.0/lxvpn/command/reference/lesr40lp2p.html

ECMP (Equal Cost Multipath Protocol) Link Bundle hashing for PWs (pseudo wires) on Layer 3 NNI (Network to Network Interface) is now based on Virtual Connection labels

In Cisco IOS XR software Release 3.7.3 as part of pseudo wire flood optimization, the Layer 3 interface list for a pseudo wire is now based on Virtual Connection labels. By using ECMP Link Bundle hashing, the Layer 3 interface list for a pseudo wire can be condensed to a single Layer 3 interface. This Layer 3 interface (slot and network protocol flood mask) is derived from the ordered array of Layer 3 interface list (masks).

Early Fast Discard command

Cisco IOS XR software Release 3.7.3 added support for the Early Fast Discard command. This command was added to process all high priority packets

Command syntax:

(config)# hw-module location <loc> early-fast-discard		
	(config-early-fast-discard)# mode [outer-encap-only | include-inner-encap]	
	(config-early-fast-discard)# vlan-cos <0-8> vlan-op [lt | ge]
	The defaults are 6 and ge (greater than or equal to)
	(config-early-fast-discard)# ip-prec <0-8> ip-op [lt | ge]	
	The defaults are 6 and ge (greater than or equal to)
	(config-early-fast-discard)# mpls-exp <0-8> mpls-op [lt | ge]	
	The defaults are 6 and ge (greater than or equal to)
(config)# no hw-module location <loc> early-fast-discard		

Power Management multiple override mechanism

Cisco IOS XR software Release 3.7.3 added support for the user to override the Power Management feature in order to configure extra line cards without full power supply redundancy.

This feature allows a card to be forced to power up, regardless of an unprogrammed EEPROM power draw value. As with the ROMMON variable, this feature is intended for temporary use. After the cookie value has been programmed, remove this configuration by repeating the CLI command with the ''no'' option.

Command example:

RP/0/RSP0/CPU0:ios(admin-config)# hw-mod power override location <loc>
 
   

The IGMP Snooping feature no longer removes the state after a port goes down

Starting with Cisco IOS XR software Release 3.7.3, mrouter and membership states on the Cisco ASR 9000 Series Aggregation Services Router no longer need to be relearned after a port goes down. Once a port goes down, the IGMP Snooping feature immediately removes all group membership states from that port. Once an mrouter port goes down, the IGMP Snooping feature removes the port from the list of mrouter ports and removes that port from the flood set of all multicast routes.

New CLI:

tcn_relearning [cisco | rfc4541 | none]

For more information on the IGMP Snooping feature on the Cisco ASR 9000 Series Aggregration Services Router router, refer to the Implementing Layer 2 Multicast using IGMP Snooping on Cisco ASR 9000 Series Routers section in the Cisco ASR 9000 Series Aggregation Services Router Multicast Configuration Guide here:

http://www.cisco.com/en/US/docs/routers/asr9000/software/multicast/configuration/guide/mcasr9kigsn.html

The VRRP & FRR failover time is no longer greater than 1 sec after a hardware module reload

Cisco IOS XR software Release 3.7.3 improves the Cisco ASR 9000 Series Aggregation Services Router VRRP & FRR failover time after a hardware module reload to less than or equal to one second.

The VPLS preferred path fallback enable option is now supported on the Cisco ASR 9000 Series Aggregation Services Router

Layer 2 VPNs can provide pseudo wire resiliency through their routing protocols. When the connectivity between end-to-end PE routers fails, an alternative path to the directed LDP session and the user data takes over. With Cisco IOS XR software Release 3.7.3, the user can fall-back to the preferred path once it has been restored.

32k EFPs/HQOS/ANCP/ACL/IGMP EFP up time > 30 minutes. This enhancement provides a five minute improvement over Cisco IOS XR software Release 3.7.2.

Starting with Cisco IOS XR Software Release 3.9 the pw-class class name encapsulation mpls command control-word option default is now disable -In Cisco IOS XR Software Release 3.9 and above the control word is disabled by default. To configure the control word, enter the control-word keyword shown in the following example:

pw-class class1 encapsulation mpls control-word

For configured policer rates of less than 1 Mbps, the actual policer rate can be approximately 10 percent less than the configured rate. For example, for a configured policer rate of 500 kbps, the actual policer rate is 448 kbps due to a granularity round down in hardware.

In Cisco ASR 9000 Series Aggregation Services Router Software Release 4.0.0, the minimum configurable logging buffered size has been increased to 307200. Any configuration with a value less than 307200 fails to upgrade to Release 4.0.1.

Run the show configuration failed startup command on startup to display the failed configuration.

Workaround: Prior to upgrading to Release 4.0.1, set the logging buffer size to a value of 307200 or greater (logging buffered 307200).

dsu mode Command Default—For E3 interfaces on the 4-Port Clear Channel T3/E3 SPA that interoperate with E3 interfaces on a Cisco 10000 Series router, the default data service unit (DSU) mode is digital-link. To change the DSU mode to cisco, configure scrambling.

For Cisco IOS XR Software Release 4.0.0 and above the hw-module location <LOC> reload warm command has been disabled. This means that the warm reload feature has been disabled.

In Cisco ASR 9000 Series Aggregation Services Router Software Release 4.1.0, you use the cablelength short command to set a cable length of 655 feet or shorter for a DS1 link on a 4-Port Channelized T1/E1 SPA. The cablelength short command options are listed as follows:

RP/0/RSP0/CPU0:vkg_ro1_a(config-t1)#cablelength short ?
  133ft  0-133ft
  266ft  134-266ft
  399ft  267-399ft
  533ft  400-533ft
  655ft  534-655ft
 
   

However, when using the cablelength short command on a 4-Port Channelized T1/E1 SPA in Cisco ASR 9000 Series Aggregation Services Router Software Release 4.1.0, only the 133ft option (for cable lengths from 0 to 133 feet) works. The other values that are greater than 133 feet (266, 399, 533, or 655) all cause the T1 controller to go down. The workaround is to restart the controller after you set the cable length to 266, 399, 533, or 655 feet. The cablelength long command works correctly.

On rare occassions, during Cisco IOS XR Software Release 4.2.0 testing, we have observed issues while making bulk configuration changes (1000+ lines) in a single configuration (Using copy (remote) running, commit replace and rollback.) We recommend that you archive configurations before executing bulk configuration changes on this scale in Cisco IOS XR Software Release 4.2.0. This way you can easily retry or compare results.

Caveats

Caveats describe unexpected behavior in Cisco IOS XR Software releases. Severity-1 caveats are the most serious caveats; severity-2 caveats are less serious.

This section lists the caveats for Cisco ASR 9000 Series Aggregation Services Router Software Release 4.2 and the Cisco ASR 9000 Series Aggregration Services Router platform.

Open Cisco IOS XR Software Release 4.2 Caveats

The following open caveats apply to Cisco IOS XR Software Release  and are not platform specific:

CSCtw80900

Basic Description:

420-PSI: After router reload, new configuration is not applied.

Symptom:

1. When performing a commit replace, a syslog similar to the following is displayed:

RP/0/RSP0/CPU0:Dec 20 05:02:45.555 : sysdb_mc[399]: %SYSDB-SMC-7-TIMEOUT : Message 
#0x200088ed state:0x13fe5326, gid(1009),destined for all local, timed out having 
received 7 of 8 expected responses: returning received responses to client config. 
Check for potential transport issues within the system, or deadlocked SysDB processes.

2. Following a router reload or LC OIR, configuration that had been previously removed by the commit replace operation reappears in the active running configuration.

Conditions:

The following two conditions are the reasons:

1. The configuration that is being replaced is either,

a. larger than 20MB (ASCII), or

b. over 100,000 interfaces on a single LC

2. The configuration changes involves a Viking RSP3 LC with the following types:

0/1/CPU0        A9K-MOD80-SE              IOS XR RUN       PWR,NSHUT,NMON
0/5/CPU0        A9K-24x10GE-SE            IOS XR RUN       PWR,NSHUT,MON
0/0/CPU0        A9K-8T/4-E                IOS XR RUN       PWR,NSHUT,MON
0/4/CPU0        A9K-2T20GE-E              IOS XR RUN       PWR,NSHUT,MON
0/5/CPU0        A9K-2x100GE-TR            IOS XR RUN       PWR,NSHUT,MON
0/6/CPU0        A9K-24x10GE-SE            IOS XR RUN       PWR,NSHUT,MON
0/7/CPU0        A9K-4T-E                  IOS XR RUN       PWR,NSHUT,MON
 
   
 
   
 
   

Workaround:

If you see the SYSDB-SMC-7-TIMEOUT error message described in Symptom 1 above, and have not yet performed any additional commits,and have not yet performed a router reload or LC OIR:

Repeat the original commit replace command, until you do not see the sysdb_mc syslog any more.

If you see the SYSDB-SMC-7-TIMEOUT error message described in Symptom 1 above, and you have performed some addtional configuration commits, and have not yet performed a router reload or LC OIR:

1. Execute show running and verify that the running configuration is what you want.

2. Execute cfs check twice to make sure the running and saved configurations are now in sync and saved properly.

If you have already performed a router reload or LC OIR and see only old configuration:

You have two options:

Option 1:

1. rollback to the point where you see the sysdb_mc syslog.

2. repeat the original commit replace operation.

3. repeat any subsequent configuration changes.

Option 2: wipe out all the configuration via commit replace and re-apply the settings you want to apply.

After doing Option 1 or Option 2:

1. Execute show running and verify that the running configuration meets your needs.

2. Execute cfs check twice to make sure that the running and saved configuration are now in sync and saved properly.

Recovery:

None.

CSCtt92490

Basic Description:

xml_tty_agent procedure crash when xml help is requested.

Symptom:

Help for CLI over XML does not work. XML agent process does not respond after the request for returning help on CLI show command.

Conditions:

When ACT software sends an XML request to the router for help hints, the XML agent did not respond and ACT was blocked. In addition, the Help hints returned were not correct.

Workaround:

None. When this is observed on a setup, it can be safely ignored assuming that the hardware under test is functioning good.

Recovery:

None.

CSCtu31007

Basic Description:

IPv6 LPTS entry was missing for some bundle interfaces. The IPv6 ND packets did not go through and IPv6 traffic was dropped at affected bundle interfaces.

Symptom:

IPv6 protocol peering neighbor sessions flapping; IPv6 traffic could not pass.

Conditions:

The bundle interfaces are on CRS-3 linecards. The issue may happen after scaled configuration is restored by either commit replace or router reload.

Workaround:

Restart pifibm_server_lc process on the bundle member linecards.

Recovery:

None.

CSCtt38345

Basic Description:

The SNMP duplicate request dropping feature is not working.

Symptom:

SNMP duplicate request dropping feature is supposed to drop requests from the same NMS and port with the same request ID, and if the number of requests in queue is greater than 20. This feature is not working in 4.2.

Conditions:

SNMP duplicate request dropping feature is supposed to drop requests from the same NMS and port with the same request ID and if the number of requests in queue is greater than 20.

Workaround:

None.

Recovery:

None.

CSCtt30049

Basic Description:

Slow SNMP response issue when polling IFMIBs with random-order.

Symptom:

Slowing down of SNMP response time is seen and the rate drops to about 45 packets/second under certain conditions.

Conditions:

1. When SNMP requests are sent from one NMS/ source IP at a rate greater than 3,000 packets/sec

2. When SNMP requests are sent from 18 source IPs / 18 NMS stations at a rate of 500 packets/sec or more

3. When CLI commands (for example, config, show commands) are being run while SNMP requests are being sent by NMS, even at a rate of about 500 packets/sec

4. SNMP response is slow when polling ifmibs in random-order

Workaround:

The above conditions may not be normal scenarios and could be avoided. For example, limit the number of NMSes to 15 or less and their polling frequency. When this is observed on a setup, the hardware under test is assumed to be functionally good in routing/switching.

Recovery:

Avoid concurrently running heavy CLI commands/processing and sending high rate of SNMP requests from NMS. Avoid the above conditions if the system gets into a state of slow response to SNMP requests.

CSCtw81342

Basic Description:

Alternate path is used for Inter-AS P2MP TE forwarding after LC reload.

Symptom:

After LC OIR affecting egress interface for a P2MP midpoint sub-lsp, the tunnel sub-lsp gets signaled over a path different from one specified at head. Traffic is not impacted.

Conditions:

1. Inter-AS P2MP tunnel.

2. LC OIR affects egress interface for the sub-LSP.

3. RIB does not withdraw the route to the next-hop address (in down state)- this is timing issue related.

Workaround:

1. At head (for affected destination), create a higher preference path-option (lower index) with same properties, and force reoptimization of the tunnel.

2. Shut/no shut the p2mp tunnel recovers the sub-LSP on the correct path.

or,

3. Disable/no disable the p2mp destinatio at head.

Recovery:

None.

CSCtt31599

Basic Description:

Incorrect pw-type after configuration rollback due to configuration failure.

Symptom:

After a configuration reject, the pw-type changes from Ethernet-VLAN to Ethernet.

Conditions:

The issue is seen with the following sequence of config steps:

1. Start with

l2vpn
logging
pseudowire
!
pw-class c1
encapsulation mpls
control-word
transport-mode vlan
 
   

2. Now configure

l2vpn
logging
pseudowire
!
pw-class mpls_class
encapsulation l2tpv3
transport-mode vlan

3. This configuration gets rejected and the configuration applied in step 2 is rolledback.

4. All the PWs that are using this class now have the pw-type as Ethernet instead of Ethernet-vlan.

Workaround:

To recover, re-apply configuration from step1, though the running configuration after step 4 shows the same as in step 1.

Recovery:

None.

CSCtt39429

Basic Description:

420: Copy of 4K static route shown fail, although successful.

Symptom:

Copying of 4K static route shows error, although successful.

Conditions:

When trying to copy 4k static route configuration to running configuration, an error appears stating, "Failed to commit one or more configuration items". However, there is no failure.

Workaround:

None.

Recovery:

None.

CSCtw62111

Basic Description:

Running RCMD diag script may lead to RP Reload.

Symptom:

In one specific manifestation, the GSP process could crash with the following message:

gsp[238]: %OS-gsp-3-MUTEX_OP_FAILED : get_sgrp_gid: Mutex op cond_wait failed on mutex 
grp_cond (RDS_CGRP_/etc/eem_rdsfs_1) : Connection timed out : pkg/bin/gsp : 
(PID=627769708)
 
   

There are other possible manifestations for other infra process restarts or deadlocks.

Conditions:

When RCMD diagnostics mode is enabled using the following CLI, the RCMD EEM diagnostics script collects debug information from various components within the router.

config
  router-convergence
    collect-diagnostics <>
  event manager policy rcmd_diags.tcl username <>
 
   

In certain scenarios, where the CPU utilization is high (100%) over a period of time and the diagnostics script gets triggered, it could create race conditions which causes deadlocks and some processes to restart, leading to reload of the RP.

Workaround:

Disable the RCMD diagnostics script by not registering the EEM policy.

Remove the following CLI:

config
  router-convergence
    collect-diagnostics <>
  event manager policy rcmd_diags.tcl username <>
 
   

Recovery:

None.

Further Problem Description:

It is recommended not to use the RCMD diagnostics feature in 4.2.0 in the production deployment, due to possible delays and deadlocks in the XR infrastructure in certain race conditions while CPU is running at 100% for an extended period.

CSCtw47793

Basic Description:

IP/LDP LFA does not choose TE Tunnel as backup with use-candidate-only.

Symptom:

TE Tunnel may not be chosen as IP/LDP LFA FRR back-up route.

Conditions:

The defect is seen when ISIS has a directly connected neighbor and also a TE tunnel to the directly connected neighbor. If the 'use-candidate-only' is configured with the TE tunnel as the only candidate, the back-up is not calculated.

Workaround:

Do not to use the use-candidate-only feature in this scenario. Instead, use explicit exclude statements for excluding interfaces from being used as a back-up.

Note that this defect would not occur if the Tunnel destination was multiple hops away from ISIS or if ISIS does not have a direct adjacency with the tunnel destination.

Recovery:

None.

CSCti50227

Basic Description:

Not able to modify RPL and delete prefix-set in a single commit.

Symptom:

When a policy that is attached directly or indirectly to an attach point needs to be modified, a single commit operation cannot be performed when:

Removing a set or policy referred by another policy that is attached to any attach point directly or indirectly.

Modifying the policy to remove the reference to the same set or policy that is getting removed.

Workaround:

The commit must be performed in two steps:

1. Modify the policy to remove the reference to the policy or set and then commit.

2. Remove the policy or set and commit.

Caveats Specific to the Cisco ASR 9000 Series Aggregration Services Router Router

The following caveats are specific to the Cisco ASR 9000 Series Aggregration Services Router platform:

CSCts69912

Basic Description:

420-UI: ipv4-mfwd-partner trace back following a crash after night run.

Symptom:

An ipv4-mfwd-partner process crash is observed on the SIP-700 LC on the ASR9K system in an overnight traffic test.

Conditions:

This problem is observed after the initial router reload and after an extended traffic test, typically in an overnight test. The ipv4_mfwd_partner process crashes on the SIP-700 and recovers by itself. There is no impact of multicast traffic when this crash is observed. Once the process recovers, no subsequent crashes have been observed in a longevity test.

Workaround:

None.

Recovery:

Recovers on its own. If NSF is configured for multicast then there is no impact on traffic. The process restarts and recovers.

CSCtw44911

Basic Description:

420-SIT: PTP master configuration is deleted on slave in case of partial delete.

Symptom:

After setting up multiple PTP masters in the master table of an interface or profile, attempting to delete one master from the table results in the deletion of the entire table.

Conditions:

After setting up masters, for example,

RP/0/0/CPU0:ios#config
RP/0/0/CPU0:ios(config)#interface gigabitEthernet 0/2/0/1
RP/0/0/CPU0:ios(config-if)#ptp
RP/0/0/CPU0:ios(config-if-ptp)#master ipv4 10.0.0.2
RP/0/0/CPU0:ios(config-if-ptp)#master ipv4 10.0.0.3
RP/0/0/CPU0:ios(config-if-ptp)#master ethernet AB34.657D.8970
RP/0/0/CPU0:ios(config-if-ptp)#master ipv6 11::AF
 
   

Trying to delete one of these masters will result in the entire table being deleted, for example,

RP/0/0/CPU0:ios#config
RP/0/0/CPU0:ios(config)#interface gigabitEthernet 0/2/0/1
RP/0/0/CPU0:ios(config-if)#ptp
RP/0/0/CPU0:ios(config-if-ptp)#no master ipv6 11::AF
 
   

If the above command is executed, the entire master table will be deleted, not just the IPv6 entry. This issue only affects the 4.2.0 release.

Workaround:

None.

Recovery:

If this is observed, all PTP masters for that interface or profile must be re-entered.

CSCtw85241

Basic Description:

420-UI: TM latency> 50 millisec causing Tail Drops on Trident for l2vpn.

Symptom:

On trident LC, observed packet drop in l2vpn traffic stream.

Conditions:

On steady state, on Trident LC, traffic drop is observed on l2vpn traffic stream, approximately every 5 to 15 minutes.

Workaround:

There is no known workaround.

Recovery:

There is no known recovery.

CSCtw93296

Basic Description:

Not all MCAST traffic is replicated towards the egress LC.

Symptom:

Not all MCAST traffic is replicated towards the egress LC.

Conditions:

On RSP3/Colossus system, not all MCAST traffic is replicated towards egress LC.

Condition is observed with at least 64K OLE configured on 1 NP.

Workaround:

Problem is not seen when egress line rate fallS below 94%.

Recovery:

None.

CSCtw80943

Basic Description:

Ethernet SLA not working over bundle-efp: DMM packet malformed.

Symptom:

SLA DMM packets are being corrupted when configured on Bundles EFPs. Corrupt packet can be seen using the following CLI output:

show ethernet cfm interfaces statistics

BEXYZ 2759 0 DMM Packet malformed - TLV offset is either too small or is beyond the end of the packet

Conditions:

Issue is seen only when Ethernet SLA is configured on Bundle EFPs on RSP3.

Workaround:

None.

Recovery:

None.

CSCtw79456

Basic Description:

Port Location is the same for two ports under two different modules.

Symptom:

The same name TenGig port is appearing under both the modules with the same location under A9K-MPA-2X10GE & A9K-MOD160-TR in entityMib.

Conditions:

Observed only with A9k-MOD160-XX cards in the ASR9k chassis having Ethernet Plugs inserted.

Workaround:

None.

Recovery:

None.

CSCtw66664

Basic Description:

CFM results differ whether obtained from RSP2 or RSP3 based routers.

Symptom:

Onthe RSP3 system, the Link trace message did not reach MEP.

Conditions:

The issue occurs when MIP is configured on the core facing bundle interface and the AC is a sub-interface (MEP). The MIP and MEP should be from two different EPs or two different linecards to see this issue of link trace failing. The linktrace reaches the MIP and will fail to reach the MEP.

Workaround:

There is no known workaround.

Recovery:

None.

CSCtw75983

Basic Description:

MWR flaps multiple times between Holdover and Acquire on asr9k reload.

Symptom:

MWR flaps multiple times between Holdover and Acquire on asr9k reload.

Conditions:

When the asr9k node is reloaded, the MWR which is slaving off the asr9k toggles multiple times between holdover and acquire before phase-lock. Following are the syslog messages observed:

%LINEPROTO-5-UPDOWN: Line protocol on Interface GigabitEthernet0/0, changed state to 
up
%TOP_MODULE-6-CLK_STATUS_CHANGE: Recovered clock status changed to ACQUIRING
%TOP_MODULE-6-CLK_STATUS_CHANGE: Recovered clock status changed to HOLDOVER
 
   

Workaround:

None.

Recovery:

It recovers on its own.

CSCtw76496

Basic Description:

Static macs are not displayed properly under show l2v forwar br mac.

Symptom:

Static mac entry still shows as a dynamic mac entry after the conversion of a dynamic mac entry to a static one via user configuration.

Conditions:

When the user creates a static mac for an already existing dynamic mac entry, or vice versa, the output of show l2vpn forwarding <> does not reflect this change. It continues to show the entry as a dynamic mac instead of a static mac entry. This is a show command display issue only and does not impact the feature or functionality.

Workaround:

None.

Recovery:

No recovery is required. It is a display only issue.

Upgrading Cisco IOS XR Software

Cisco IOS XR Software is installed and activated from modular packages, allowing specific features or software patches to be installed, upgraded, or downgraded without affecting unrelated processes. Software packages can be upgraded or downgraded on all supported card types, or on a single card (node).

Software packages are installed from package installation envelope (PIE) files that contain one or more software components. Refer to Table 1 for a list of the Cisco ASR 9000 Series Aggregation Services Router Software feature set matrix (PIE files) and associated filenames available for the Cisco IOS XR Software Release 4.2 supported on the Cisco ASR 9000 Series Aggregation Services Router.

The following URL contains links to information about how to upgrade Cisco IOS XR Software:

Troubleshooting

For information on troubleshooting Cisco IOS XR Software, see the Cisco ASR 9000 Series Aggregation Services Routers Getting Started Guide and the Cisco ASR 9000 Series Router Troubleshooting Feature Module.

Resolving Upgrade File Issues


Note In some very rare cases inconsistencies in the content of the internal configuration files can appear. In such situations, to avoid configuration loss during upgrade, the following steps can be optionally done before activating packages:


a. Clear the NVGEN cache:

RP/0/RSP0/CPU0:router# run nvgen -F 1
 
   

b. Create a dummy config commit:

RP/0/RSP0/CPU0:router# config
RP/0/RSP0/CPU0:router(config)# hostname <hostname>
RP/0/RSP0/CPU0:rotuer(config)# commit
RP/0/RSP0/CPU0:router(config)# end
 
   

c. Force a commit update by using the reload command. Press n when the confirmation prompt appears:

RP/0/RSP0/CPU0:router# reload
Updating Commit Database. Please wait...[OK]
Proceed with reload? [confirm] 
 
   

d. Press n.

In some cases other activity may preclude a reload. The following message may display:

RP/0/RSP0/CPU0:router# reload
Preparing system for backup. This may take a few minutes ............System 
configuration backup in progress [Retry later]
 
   

If you receive this message wait and then retry the command after some time.
