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 XR 12000 Series Router provides the following features and benefits:

IP and RoutingSupports 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).

BGP Prefix Independent ConvergenceProvides 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 with out MPLS. This fast convergence innovation is unique to Cisco IOS XR software.

Multiprotocol Label Switching (MPLS)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—Provides comprehensive IP Multicast software including Source Specific Multicast (SSM) and Protocol Independent Multicast (PIM) in Sparse Mode only.

Quality of Service (QoS)—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—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—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—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—Delivers IPv6 traffic over an IPv4/MPLS core with IPv6 provider edge router (6PE) support.

IPv6 VPN over MPLS (6VPE) support—Delivers IPv6 VPN over MPLS (IPv6) VPN traffic over an IPv4 or MPLS core with 6VPE support.

6VPE over L2TPv3 support—Delivers IPv6 VPN traffic over L2TPv3 core with 6VPE support. This feature is also available on Cisco IOS software.

Enhanced core competencies:

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

Path Computation Element (PCE) capability for traffic engineering

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. The 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 4.0.0, see the "New Features in Cisco IOS XR Software Release 4.0.0" section in this document.

For Engine 5 line card:

Maintenance Bus (MBUS) Agent Software-RAM version 04.06, ROM version 04.06

ROM Monitor version 17.1

Fabric Downloader - RAM version 6.1, ROM version 4.7 (The ROM version will be the same as the RAM version if upgraded.)

Route processors (RPs)

For Performance Route Processor 2 (PRP-2):

Maintenance Bus (MBUS) Agent Software-RAM version 04.06, ROM version 04.06

ROM Monitor version 1.24

For Performance Route Processor 3 (PRP-3):

Maintenance Bus (MBUS) Agent Software-RAM version 04.06, ROM version 04.06

ROM Monitor version 1.4.0

Minimum Firmware Requirement

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


Note The 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:

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 administration EXEC 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:

http://www.cisco.com/web/Cisco_IOS_XR_Software/pdf/XR12000SoftwareFirmwareCompatibilityMatrix.pdf

Links to PDF copies of the IOS XR Firmware Upgrade Guides are available online here:

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 4.0.0:

Cisco IOS image—12.0(32)S

Cisco IOS Boothelper—12.0(32)S0a

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 the Migrating from Cisco IOS to Cisco IOS XR Software on the Cisco XR 12000 Series Router document.

Determining Your Software Version

To determine the version of Cisco IOS XR software running on your router, log into the router and enter the show version command:


Step 1 Establish a Telnet session with the router.

Step 2 Enter the show version command from EXEC mode.

New Hardware Features for the Cisco XR 12000 Series Router

No new hardware features were introduced in Cisco IOS XR Software Release 4.0.0 on the Cisco XR 12000 Series Router.

For detailed information on the shared port adapters (SPAs) and SPA interface processors (SIPs), see the following documents:

Cisco XR 12000 Series Router SIP and SPA Hardware Installation Guide

Cisco Interface and Hardware Component Configuration Guide for the Cisco XR 12000 Series Router, Release 4.0


Note Contact gsr-pm@cisco.com for hardware availability.


Important Notes

Default timestamp setting—The timestamp prompt that precedes console output is enabled by default in Cisco IOS XR Release 3.8. To disable the timestamp prompt, use the no service timestamp command. For more information, refer to theCisco IOS XR System Management Command Reference for the Cisco XR 12000 Series Router.

From Cisco IOS XR Software Release 3.6.0, WRED statements are collapsed in that if different random-detect statements using the same match types (EXP, DSCP, Prec, and so forth) are entered with identical minimum and maximum threshold values, a single configuration line is shown in the output of show running config. This reduces the length of the configuration but creates a problem with backward compatibility with previous releases. In such a situation, on rollback, the QoS policy is rejected and must be manually entered again.

Configuration prior to Cisco IOS XR Software Release 3.6.0:

Policy-map wred_example
   Class class-default
       random-detect exp 0 384 packets 484 packets
       random-detect exp 1 384 packets 484 packets
       random-detect exp 2 384 packets 484 packets
       random-detect exp 3 484 packets 584 packets
       random-detect exp 4 484 packets 584 packets
       random-detect discard-class 0 384 packets 484 packets
      random-detect discard-class 1 384 packets 484 packets
      random-detect discard-class 2 484 packets 584 packets
      bandwidth remaining percent 20

Cisco IOS XR Software Release 3.6.0 and later releases:

policy-map wred_example
 class class-default
  random-detect exp 0,1,2 384 packets 484 packets
  random-detect exp 3,4 484 packets 584 packets
  random-detect discard-class 0,1 384 packets 484 packets
  random-detect discard-class 2 484 packets 584 packets
  bandwidth remaining percent 20
 !
 end-policy-map
!
end 
 
   

In Cisco IOS XR Software Release 3.6.0 and later releases, the implicitly assigned QoS class class-default must have at least 1 percent bandwidth made available to it. This can be done either by assigning at least 1 percent explicitly (bandwidth remaining percent 1) or by ensuring that the total bandwidth assigned to all other classes in the policy is a maximum of 99 percent, leaving 1 percent available for the class-default. A QoS policy that does not have any bandwidth for class-default is rejected when upgrading to Cisco IOS XR Software Release 3.6.0 or later releases.

Country-specific laws, regulations, and licences—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 RP removal—For all card removal and replacement (including fabric cards, line cards, fan controller, and RP) 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:

RP/0/0/CPU0:router# admin
RP/0/0/CPU0:router# show environment power-supply table
48V       Current

If 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.


Note No 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.

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.

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.

Disable/Enable RSVP Message Checksum Starting with Cisco IOS XR Software Release 4.0.0, 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 4.0.0 default behavior and go back to pre Cisco IOS XR Software Release 4.0.0 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 4.0.0 behavior is:

Router(config)#rsvp signalling checksum disable
 
   

Note When 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.


Minimum Flash Disk Requirements When Upgrading to Release 4.0.0

Cisco IOS XR Software Release 4.0.0 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 4.0.0. 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:

http://www.cisco.com/en/US/products/ps6342/prod_installation_guides_list.html

Minimum Firmware Requirement

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


Note The 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:

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 administration EXEC mode.

upgrade all location {node-id | all} [force]

Where location node-id specifies that all firmware images (ROM, MBUS, Fabric Downloader and FPD) 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 firmware images (ROM, MBUS, Fabric Downloader and FPD) 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:

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 4.0.0 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 4.0.0 and are not platform specific:

CSCte01589

Basic Description:

xml_tty_agent coredump during XML polling

Symptom:

The xml_tty_agent process will coredump on a DRP card.

Conditions:

This symptom occurs when querying the diagnostic xml schema.

Workaround:

None.

Recovery:

None needed, the process will restart properly

CSCti30460

Basic Description:

length and width not reflected in newly opened vty session

Symptom:

length and width size not reflected newly opened vty session instead it take in to effect on already opened vty

Conditions:

we may see this issue after configuring length and width config in vty by template

Workaround:

None.

Recovery:

None.

CSCti40614

Basic Description:

4.0.0 :29C: sh tech l2vpn file not able to untar/corrupted

Symptom:

1. The file created cannot be untarred properly. Indicates a corrupted file

2. The show tech takes a VERY long time

Conditions:

On a large scale system, with show tech l2vpn, it is possible to exceed the max supported tar file size.

Workaround:

This was the reason for adding a few new show tech l2vpn options in 4.0:

1. show tech l2vpn [control | platform ]

This option essentially allows the show tech to be either PI specific (control option) or it can be PD specific (platform option)

This essentially split the normal full show tech output in two. This reduces the chance of exceeding the current 2Gig limit for the show tech. It also allow a faster collection of show tech if it is knows in which area the problem exists.

2. show tech l2vpn location 0/0/CPU0

This option collects general system information and information specific to only the slot specified.

This greatly reduces the size of the output and also greatly speeds up the execution of the show tech. This is recommended on large system with lot of card specially Multi chassis configuration.

The source of the problem needs to be pinpointed. In not then this commands can still be executed serially for each cards in the system.

CSCth81761

Basic Description:

%ROUTING-BGP-3-NEGCOUNTER msgs after router reload or APS switchover

Symptom:

%ROUTING-BGP-3-NEGCOUNTER msgs seen on console

Conditions:

The error messages were seen on performing a router reload or during APS switchover

Workaround:

None.

CSCtg40080

Basic Description:

Show mrib route does not show proper "Flag" output for ExtranetV6

Symptom:

Flag field is incorrect in "show mrib route"

Conditions:

When you have IPv6 MVPN enabled.

Workaround:

There is no work around. It is a show command issue.

Further Problem Description:

None.

CSCti48713

Basic Description:

SONET_SDH xml does not bind to correct path for history stats

Symptom:

'PM get path data failed : Invalid argument ' message will be displayed on the console

Conditions:

This symptom is observed when querying the SONET_SDH xml schema.

Workaround:

None.

Recovery:

None.

CSCti67148

Basic Description:

Optional task-maps not downloaded as part of exec authorization & Service exec tasks received from the TACACS server are not processed during AAA authorization

Symptom:

Command authorization fails:

RP/0/RP0/CPU0:router#show int desc
% This command is not authorized
RP/0/RP0/CPU0:router#

Conditions:

This happens:

On a router running IOS XR 3.9.2 or 4.0.0. These are the only 2 versions affected. It did not happen before and it's fixed afterwards.

Tacacs authorization is enabled.

Router is supposed to retrieve its list of usergroup/taskgroup/task from the tacacs server through a service exec (optional) task configured on the tacacs server.

The problem with this bug is that the service exec tasks received from the tacacs server are not processed during aaa authorization with tacacs. So the user ends up with no task on the router and no command is authorized. Even though the command is permitted on the tacacs server.

Workaround:

Instead of using wild cards, explicitly name each package to be activated.

Recovery:

The way to make tacacs authorization work in 3.9.2 or 4.0.0 is through a privilege level:

If privilege level 15 is assigned on the tacacs server, then user will end up with the tasks/commands of the group root-system.

If privilege level 14 is assigned on the tacacs server, then user will end up with the tasks/commands of the group owner-sdr.

If a privilege level between 1 and 13 (let's call it X), then we can configure a usergroup 'privX' on the router and the user will inherit the list of tasks of that group. For instance, if we want to have a user with all commands available, we can assign privilege level 13 on the router and configure this usergroup on the router:

usergroup priv13
  taskgroup root-system
  taskgroup cisco-support
 
   

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 XR 12000 Series Router

The following open caveats are specific to the Cisco XR 12000 Series Router:

CSCti81797

Basic Description:

Line protocol is down in POS interface after executing a shut/unshut command on the controller.

Symptom:

The POS interface line protocol goes down after executing a shut/unshut command on the controller.

Conditions:

Occurs after user executes a shut/unshut command on the controller

Workaround:

None.

Recovery:

Perform a shut/no shut of the SONET controller after the issue is seen to recover from the issue.

CSCti23140

Basic Description:

vpls multicasting is not happening if IPHC configured on core-facing LC

Symptom:

VPLS multicast does not function appropriately.

Conditions:

This is observed on a Cisco 12000 series router with IPHC configured on same line card slot on which a vpls core facing interface is present.

Workaround:

None, do not configure IPHC on the same slot with a core facing SPA

Recovery:

None.

CSCth07758

Basic Description:

ipv4_mfwd_partner process crashed during downgrade from 3.9.1

Symptom:

The ipv4_mfwd_partner process exits ungracefully.

Conditions:

This symptom is observed while downgrading from IOS XR Release 4.0.0 to Release 3.9.1.

Workaround:

None.

Recovery:

Recovery action is not needed here. The process will recover on its own with no impact to traffic.

CSCtf48225

Basic Description:

XR fdiags Superfish TFIA To FFIA Fabric Pkt Test fails on 12404E chassis

Symptom:

XR fdiags Superfish TFIA To FFIA Fabric Pkt Test fails on 12404E chassis

Conditions:

No service impact.

Workaround:

None.

Recovery:

None.

Resolved Cisco IOS XR Software PSIRT-Related Caveats

CSCti62211

Basic Description:

BGP flaps due to unknown attribute

Symptom:

Cisco IOS XR Software contains a vulnerability in the Border Gateway Protocol (BGP) feature. The vulnerability manifests itself when a BGP peer announces a prefix with a specific, valid but unrecognized transitive attribute. On receipt of this prefix, the Cisco IOS XR device will corrupt the attribute before sending it to the neighboring devices. Neighboring devices that receive this corrupted update may reset the BGP peering session.

Conditions:

Affected devices running Cisco IOS XR Software corrupt the unrecognized attribute before sending to neighboring devices, but neighboring devices may be running operating systems other than Cisco IOS XR Software and may still reset the BGP peering session after receiving the corrupted update. This is per standards defining the operation of BGP.

Workaround:

No workaround. Cisco developed a fix that addresses this vulnerability and will be releasing free software maintenance upgrades (SMUs) progressively starting 28 August 2010.

A Security Advisory is posted at http://www.cisco.com/warp/public/707/cisco-sa-20100827-bgp.shtml
