Cisco IOS XR Software running on the Cisco XR 12000 Series 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 (VRRP) features.
- 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), Resource Reservation Protocol (RSVP), Label Distribution Protocol (LDP), Virtual Private LAN Service (VPLS), 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.
- Quality of Service (QoS)—This supports QoS mechanisms including policing, marking, queuing, random and hard traffic dropping, and shaping. Additionally, Cisco IOS XR Software also supports modular QoS command-line interface (MQC). MQC is used to configure QoS features.
- 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 messages.
- Security—This provides comprehensive network security features including access 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 management plane 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).
- Craft Works Interface (CWI)—CWI is a client-side application used to configure and manage Cisco routers. Management and configuration features include fault, configuration, security, and inventory, with an emphasis on speed and efficiency. The CWI provides a context-sensitive graphical representation of the objects in a Cisco router, simplifying the process of configuring and managing the router. The CWI allows you to log in to multiple routers and perform management tasks.
- Availability—This supports rich availability features such as fault containment, fault tolerance, fast switchover, link aggregation, nonstop routing for ISIS, LDP, BGP, and OSPF, and nonstop forwarding (NSF).
- Multicast service delivery in SP NGN—MVPNv4 support carries multicast traffic over an ISP MPLS core network.
- IPv6 Provider Edge Router support for IPv6 applications—This delivers IPv6 traffic over an IPv4/MPLS core with IPv6 provider edge router (6PE) support.
- IPv6 VPN over MPLS (6VPE) support—This delivers IPv6 VPN over MPLS (IPv6) VPN traffic over an IPv4 or MPLS core with 6VPE support.
- 6VPE over L2TPv3 support—This delivers IPv6 VPN traffic over L2TPv3 core with 6VPE support. This feature is also available on Cisco IOS Software.
- Enhanced core competencies:
- L2TPv3 Tunneling Mechanism—Service Providers who do not use MPLS in the core, but want to offer VPN services can use the L2TPv3 tunneling mechanism. This feature support includes IPv4 (VPNv4) and IPv6 (6VPE) VPN services using L2TPv3 encapsulation. This L2TPv3 packet is encapsulated in an IPv4 delivery header and is carried across an IPv4 backbone. VPN prefixes are advertised with BGP labels and resolved over L2TPv3 tunnels. This feature is supported only on the Cisco XR 12000 Series Router.
For more information about new features provided on the Cisco XR 12000 Series Router for Cisco IOS XR Software Release, see the "New Features in Cisco IOS XR Software Release 4.2.4" section in this document.

Minimum Firmware Requirement
The following table provides the procedures and resources for minimum firmware requirements:
- After completing an RMA the newly-received linecard may not have appropriate IOS XR firmware installed. Depending on the type of firmware that needs upgrading the symptoms can vary as follows:
- ROMMON needs updating the linecard will not boot up
- MBUS needs updating the linecard may fail to boot or keeps reloading
- Fabric Loader needs updating the linecard will take long time to boot
- FPD needs updating the linecard experiences packet corruption / drop
NoteThe FPD PIE has to be installed in order to upgrade to the latest FPD image. Refer to the Upgrading FPD on Cisco IOS XR Software chapter of the Cisco IOS XR System Management Command Reference for the Cisco XR 12000 Router online.
- RMA Card Firmware Upgrade Procedure
- Requirement of Cisco IOS Image Level and Boot Helper Version for Migration
RMA Card Firmware Upgrade Procedure
To upgrade the fabric-downloader, ROMMON, Mbus, and current field-programmable device (FPD) image package on a single RMA linecard or on all modules installed in a router, use the upgrade all command in the admin mode.
upgrade all location {node-id | all} [force]
Where location node-id specifies that all ROM images will be upgraded on the physical location of the line card received through RMA defined by the node-id argument. The node-id argument is entered in the rack/slot/module notation.
The upgrade all location all command upgrades all ROM images on all line cards (LCs) that are installed in the router.
For an RMA linecard firmware upgrade you'll want to use the upgrade all location {node-id} command
The optional force parameter skips the version check and forces an upgrade.
- The list of minimum supported firmware versions is available online in this matrix which contains links to PDF copies of the IOS XR Firmware Upgrade Guides which are available online here : http://www.cisco.com/web/Cisco_IOS_XR_Software/index.html
- Refer to the Hardware Redundancy and Node Administration Commands on Cisco IOS XR Software chapter of the Cisco IOS XR System Management Command Reference for the Cisco XR 12000 Router for the upgrade all command syntaxhttp://www.cisco.com/en/US/docs/routers/xr12000/software/xr12k_r4.0/system_management/command/reference/b_yr40xr12k_chapter_0111.html.
Requirement of Cisco IOS Image Level and Boot Helper Version for Migration
If you are migrating from Cisco IOS to Cisco IOS XR Software on the Cisco XR 12000 Series Router, you must have the following minimum Cisco IOS image level and Boothelper version to support Release 4.2.44.3.0:
If you have an earlier version of this system, you must upgrade to the minimum supported level before performing a migration. Otherwise, your migration fails. For more information, see Migrating from Cisco IOS to Cisco IOS XR Software on the Cisco XR 12000 Series Router document.
Determining Your Software Version
ProcedureTo determine the version of Cisco IOS XR Software running on your router, log in to the router and enter the show version command:
New Software Features on the Cisco XR 12000 Series Router
The following new software features are introduced in Cisco IOS XR Software Release 4.2.4 for the XR 12000 Router.
route-priority
To enable users to adjust the route-priority given to TE labels into the data plane, compared to labels and route updates from other protocols, use the route-priority command in MPLS-TE configuration mode. To return to the default behavior, use the no form of this command.
route-priority role { middle | head { primary | backup } } queue queue
no route-priority role { middle | head { primary | backup } }
Syntax Description
role Defines the role of the tunnel to which the label belongs.
middle A tunnel mid-point.
head backup A tunnel head which is assigned as a FRR backup to an interface.
head primary All other tunnel heads.
queue Defines the queue number. Range is from 0 to 12 inclusive; lower values represent higher priority queues.
Command History
Usage Guidelines
To use this command, you must be in a user group associated with a task group that includes appropriate task IDs. If the user group assignment is preventing you from using a command, contact your AAA administrator for assistance.
Use this command to change the priority given to TE labels when updates to the forwarding plane are made from the control plane.
The priority values used by other applications are:
CautionThe default prioritization of label updates from the control plane to the forwarding plane has been carefully chosen to avoid traffic loss under both normal operation and high system load, and to balance the needs of the various features that employ label switching. Changing these defaults may cause unpredictable behavior including traffic loss, especially when the router is experiencing high load. Use of this command is not recommended without proper understanding of its effects and possible side-effects.
Task ID
New Hardware Features on the Cisco XR 12000 Series Router
There are no new hardware features introduced in Cisco IOS XR Software Release 4.2.4 for the XR 12000 Router.
Important Notes on Cisco IOS XR Software and Cisco XR 12000 Series Router
- Default timestamp setting—The timestamp prompt that precedes console output is enabled by default. To disable the timestamp prompt, use the no service timestamp command. For more information, refer to the Cisco IOS XR System Management Command Reference for the Cisco XR 12000 Series Router.
- Country-specific laws, regulations, and licenses—In certain countries, use of these products may be prohibited and subject to laws, regulations, or licenses, including requirements applicable to the use of the products under telecommunications and other laws and regulations; customers must comply with all such applicable laws in the countries in which they intend to use the products.
- Migrating from Cisco IOS to Cisco IOS XR Software on the Cisco XR 12000 Series Router—When migrating a Cisco XR 12000 Series Router from Cisco IOS to Cisco IOS XR Software, follow the instructions provided in Migrating from Cisco IOS to Cisco IOS XR Software on the Cisco XR 12000 Series Router.
- Card fan controller, and RSP removal—For all card removal and replacement (including fabric cards, line cards, fan controller, and RSP) follow the instructions provided by Cisco to avoid impact to traffic. See the Cisco IOS XR Getting Started Guide for the Cisco XR 12000 Series Router for procedures.
- Exceeding Cisco testing—If you intend to test beyond the combined maximum configuration tested and published by Cisco, contact your Cisco Technical Support representative to discuss how to engineer a large-scale configuration maximum for your purpose.
- More power required for Cisco SIP line cards (SIP-401/501/600/601) on the Cisco XR 12000 Series Router—These line cards draw more power than previous generation line cards. Depending on the exact configuration of power entry modules (PEMs) and other cards in the chassis, there may not be enough power available when inserting a new card or removing a PEM. Before you insert a new card or remove a PEM, run the following command in admin mode:
To display the power used or total power or remaining power in chassis. Use the command show power-mgr detail command in EXEC mode.RP/0/4/CPU0:router(admin)#show environment power-supply table Mon Sep 24 00:56:28.054 UTC 48V Current R/S/I Module (V) (A) 0/24/* PEM1 0 0 12000/6-AC-PEM= Intelligent AC PS PEM2 52 11 12000/6-AC-PEM= Intelligent AC PS 0/25/* PEM1 0 0 12000/6-AC-PEM= Intelligent AC PS PEM2 52 9 12000/6-AC-PEM= Intelligent AC PSIf you plan to insert a new card, locate the entry for the card to be inserted and note the power consumed by it. If this power is less than the figure given in Worst Case Redundant Power Available (the figure is displayed in the show environment power-supply table command output), the card can be safely inserted. As long as the Worst Case Redundant Power Available is not zero, a PEM can be powered down for replacement without impact.RP/0/4/CPU0:router#show power-mgr detail Mon Sep 24 00:53:54.518 UTC Power management summary ------------------------ Powershelf type: AC Power Supplies Operating phase: RUNNING_PHASE Feature state : Enabled Operating mode : NON-REDUNDANT Total supply power: 1900 W Route processors: 60 W Linecards: 240 W Chassis components: 477 W Total inuse power: 777 W Remaining: 1123 W PEM1 present, but unpowered PEM2 present, supplying up to 1900 watts: uptime 0d01h39m Slot Cardtype Watts Status ---- -------- ----- ------ 1 12000-SIP-601= 240 powered 4 PRP= 60 powered 16 GSR6-CSC= 56 powered 17 GSR6-CSC= 56 powered 18 GSR6-SFC= 45 powered 19 GSR6-SFC= 45 powered 20 GSR6-SFC= 45 powered 24 GSR6-ALRM= 26 powered 25 GSR6-ALRM= 26 powered 28 GSR6-BLOWER= 178 powered
NoteNo alerts are issued if more cards are inserted than the PEMs can support. It is your responsibility to determine your power budget for the chassis before making any changes to it. Exceeding the power budget may result in the PEM being overloaded and cards powering down due to insufficient power being provided.
- Per-interface Internet Control Message Protocol (ICMP) disable feature is not supported on the Cisco XR 12000 Series Router.
- Online Diagnostics is not supported on the Cisco XR 12000 Series Router— If you execute the diagnostic command, an error appears stating that there is no online diagnostics process running on the router.
- The rp mgmtethernet forwarding command is not supported on the Cisco XR 12000 Series Router.
- Enabling the Lawful Interface feature triggers the L2-PRECAM-2-HW_RESOURCE_FAILURE message on Engine-3 linecards. This error reflects that your configuration has used up all available look-up registers (LUREGs). There is no direct workaround for this issue as its a hardware limitation. Only way to recover from this issue is to reduce feature scale. You need to identify the features which use LUREG at PreCAM1 and remove one or more of the features depending on LUREG requirements of the feature being added.
- mpls traffic engineering igp-intact command—This command must be used only when policy based tunnel selection is configured for all tunnels originating on the device. This CLI needs to be turned on under IGP (OSPF/ISIS) under the respective AFI.
- Disable/Enable RSVP Message Checksum Starting with C isco IOS XR Software Release 4.0.2, RSVP will, by default, compute and set the checksum field in all outgoing RSVP messages. Also, RSVP will verify the checksum field on all RSVP messages received to insure RSVP message integrity. A CLI is provided to override this Cisco IOS XR Software Release 4.0.2 default behavior and go back to pre Cisco IOS XR Software Release 4.0.2 behavior such that RSVP neither computes/sets the RSVP checksum on outgoing RSVP messages, nor verifies the checksum on received RSVP messages. The command to execute to revert to the pre- Cisco IOS XR Software Release 4.0.2 behavior is:
Router(config)#rsvp signalling checksum disable
NoteWhen the rsvp signalling checksum disable command is configured, RSVP sets a zero checksum in all outgoing RSVP messages, and ignores the checksum field on all received RSVP incoming messages.
- Starting from Cisco IOS XR Software Release 4.0.0, the hw-module location <LOC> reload warm command is disabled. As a result, the warm reload feature also has been disabled.
Minimum Flash Disk Requirements When Upgrading to Release 4.2.4
Cisco IOS XR Software Release 4.2.44.3.0 requires a 2-GB Flash Disk as a minimum. If your Cisco XR 12000 Series Router currently uses a 1-GB Flash Disk, you must upgrade it to 2-GB before upgrading to Cisco IOS XR Software Release 4.2.44.3.0. The PCMCIA 1-GB Flash Disk was the default size for the Cisco XR 12000 Series Router running Cisco IOS XR Software Release 3.6 and earlier.
In Cisco IOS XR Software Release 3.6 and later releases, disk partitioning is supported. Partitioning of a 2-GB disk is possible but not required. Partitioning of a 4-GB disk is required.
A 4-GB Flash Disk can be installed instead of the 2-GB for greater disk storage.
To upgrade from a 1-GB flash disk to a 2-GB or greater flash disk, refer to the Flash Disk Upgrade Tasks link on the following Cisco XR 12000 Series Router Installation and Upgrade URL:

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 contains caveats that are generic to the Cisco IOS XR Release 4.2.4 software and those specific to the Cisco XR 12000 Series Router.
Cisco IOS XR Caveats
The following open caveats apply to Cisco IOS XR Software Release and are not platform specific:
- 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. 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.
- 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: Workaround: The commit must be performed in two steps:
- CSCub15328 Basic Description: underscore "_" in a RPL regexp does not match the start of a AS-SET segment denoted as {a, b, c, ...}. Symptom: The underscore symbol "_" in an RPL regexp does not match the start of a AS-SET segment denoted as {a, b, c, ...}. Conditions: When an RPL regexp is used in either inbound route-policy or outbound route-policy, the AS-PATH string contains AS-SET segment {a, b, c, ...}. Workaround: Use rpl native as-path semantics such as as-path neighbor-is, as-path originates-from or as-path passes-through instead of the regular expressions. As-Path native semantics are more superior to ios regex. Use of regular expressions is computation intensive since regular expression is stored as a string.
- CSCub98462 Basic Description: Radiusd mem leak occurred while executing all radius related CLI on router, which is used more than 10000 bytes for each and every radius CLI. Symptom: The show radius command triggers memory leak in 'radiusd' on routers with LC nodes, more so on MC (Multi-Chassis) routers than on SC routers. Conditions: The radius is configured on the router. Workaround: Use 'location' option with the show radius command to get statistics from a particular node. On non-BNG platforms (Carrier Routing System, Gigabit Switch Router, Aggregation Service Router) statistics from only dSC/dLRSC nodes are relevant because 'radiusd' that runs on other nodes are not used for non-BNG deployments. Therefore, dSC/dLRSC node-name can be given as input to 'location' option without any loss of functionality (statistics) of the show radius command. Alternately, restart 'radiusd' if heap memory has accumulated.
- CSCuc30874 Basic Description: MGMT fails to resolve NH in ingress LC(0/6/cpu0) if prefix and NH are from different VRF (V500:U31) and imported via export-map. Symptom: Routes imported from another vrf (on another LC) shows as unresolved in cef. Conditions: When prefix (from a vrf on a LC) is exported via export route-policy with additive route-target instead of export route-target configuration to another vrf on another LC. Workaround: Use export route-target configuration to export the routes in stead of route-policy or disable selective vrf download.
- CSCuc95942 Basic Description: The snmpd process crashes with a SIGSEGV - Segementation Fault. Symptom: The snmpd process crashes with a SIGSEGV - Segementation Fault. This behavior is inconsistent. Conditions: The problem occurs shortly after the router upgrades without any changes in SNMP polling or configuration. Workaround: None. The process recovers automatically after the crash.
- CSCud64916 Basic Description: The pifibm_server_lc process crashes on the line card. Symptom: The pifibm_server_lc process crashes on the line card. Conditions: The crash is observed during the router reload, line card reload, or commit replace scenarios. Workaround: None. The process recovers automatically after the crash.
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.
