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 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). The Cisco CRS-1 router supports Layer 2 Virtual Private Network (L2VPN).

Multicast—Provides comprehensive IP Multicast software including Source Specific Multicast (SSM) and Protocol Independent Multicast (PIM) in Sparse Mode only. The Cisco CRS-1 router supports Bidirectional Protocol Independent Multicast (BIDIR-PIM).

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 simplifies the configuration of various QoS features on various Cisco platforms.

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 messaging.

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 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).

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 (Cisco XR 12000 Series Router only). 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)

Traffic engineering support for unequal load balancing

Path Computation Element (PCE) capability for traffic engineering

Firewall Services—Seamless insertion of Firewall Services in the data path with Virtual Firewall support on Multi Service Blade (XR-12K-MSB) for the Cisco XR 12000 Series Router.

VPN IPSec Aggregation —The IPSec Aggregation feature is provided through SPA-IPSEC-2G-2 card. The IPSec Aggregation feature allows you to terminate up to 64-K VPN tunnels, both site-to-site and remote access, if four VPN SPAs are used.

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 various platforms for Cisco IOS XR Software Release 3.8.0, see the "New Features and Enhancements" section in this document.

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 XR 12000 Series Routers running Cisco IOS XR Software Release 3.8.0 consist of the following:

2-GB route memory on performance route processor 2 (PRP-2)


Note 4-GB route memory on PRP-2 is required if it is planned to scale to more than 64K IPsec tunnels per chassis.


2-GB or greater ATA flash storage on PRP-2

4-GB route memory on performance route processor 3 (PRP-3)

2-GB or greater Compact flash storage on PRP-3

1-GB line card route memory on all Engine 3 line cards

1-GB line card memory on Engine 5-based SPA interface processor (SIP-600)

The default route memory on the 12000-SIP-600 is 1GB

2-GB line card memory on all Engine 5-based SPA interface processors (SIPs)

The default route memory on the 12000-SIP-401, 501, and 601 is 2 GB.


Note The performance route processor 1 (PRP-1) is not supported in production environments.


2-GB PCMCIA Flash Disk


Note Cisco IOS XR Software Release 3.8.0 requires a 2-GB Flash Disk as a minimum. Therefore, you must upgrade an existing PCMCIA 1-GB Flash Disk to 2 GB before upgrading to Cisco IOS XR Software Release 3.8.0.

Note If you are running Cisco IOS XR software on a Cisco XR120xx system with SIP 600, 401, 501, or 601, you must upgrade the fabric. For ROMMON, MBUS, and Fabric Downloader versions, see the "Other Firmware Support" section.


Other Firmware Support

The Cisco XR 12000 Series Router supports the following firmware:

Line card (LC)

Maintenance Bus (MBUS) Agent Software-RAM version 4.4, ROM version 4.4

ROM Monitor version 17.1

Fabric Downloader - RAM version 8.0/4.7, ROM version 8.0/4.7 (The ROM version will be the same as the RAM version if upgraded.)

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 3.8.0:

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.

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 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 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:

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:

http://www.cisco.com/en/US/docs/ios_xr_sw/iosxr_r3.8/system_management/command/reference/yr38hw.html

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.

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 timestamp disable command. For more information, see http://www.cisco.com/en/US/docs/ios_xr_sw/iosxr_r3.8/system_management/command/reference/yr38term.html#wp1311395.

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 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 Cisco XR 12000 Series Routers.

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.

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.

Minimum Flash Disk Requirements When Upgrading to Release 3.8.0

Cisco IOS XR Software Release 3.8 requires a 2-GB Flash Disk as a minimum, so if your Cisco CRS-1 or 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 3.8. The PCMCIA 1-GB Flash Disk was the default size for the Cisco CRS-1 and Cisco XR 12000 Series Router running Cisco IOS XR Software Release 3.6 and earlier.

A 4-GB Flash Disk is available for both platforms and 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 Cisco XR12000 and CRS-1 Flash Disk Upgrade Tasks document at http://www.cisco.com/en/US/docs/routers/xr12000/xr_line_cards/flashdisk/flashdisk.pdf.

Additional upgrade instructions for the Cisco CRS-1 router are available from http://www.cisco.com/web/Cisco_IOS_XR_Software/pdf/ReplacingPCMCIACardOnCRS-1.pdf.

Caveats

Caveats describe unexpected behavior in Cisco IOS XR software releases. Severity-1 caveats are the most serious.

The following caveats are open for Cisco IOS XR Software Release 3.8.0 on the router platforms indicated:

Cisco IOS XR Caveats

Caveats Specific to the Cisco CRS-1 Router

Caveats Specific to the Cisco XR 12000 Series Router

Cisco IOS XR Caveats

The following caveats apply to both platforms:

CSCsm49789

Basic Description:

This bug results in an IS-IS adjacency going down on an interface, typically following an event such as interface flap or IS-IS process restart. The cause of the bug is a race condition inside the LPTS Port Arbitrator with respect to the delete and re-addition of the binding for the IS-IS adjacency.

Specifically, when this bug is encountered, the hardware LPTS pre-ifib database does not contain an IS-IS entry for the interface, whereas the software LPTS pre-ifib does contain it.

The two databases can be verified by looking at show lpts pifib hardware entry type isis location node-id and show lpts pifib entry type isis location node-id, respectively.

Symptoms:

IS-IS adjacency is down on an interface, with the hardware LPTS database showing missing entries.

Conditions:

Delays in updating the TCAM entries and other related clean-up when an LPTS binding for the IS-IS adjacency is removed.

Workaround:

None.

Recovery:

Restart the pifibm_server on the LC where the IS-IS interface is present. If that does not help, a restart of lpts_pa should fix the problem. The restarts should not cause issues for other routing protocols.

CSCsx03068

Basic Description:

Leak in bfd_agent process after multiple SPA OIRs.

Symptom:

1.6 k of memory leak is seen in bfd_agent process after multiple SPA OIR events.

Conditions:

SPA OIR causes a tiny memory leak which leads to process restart after several hundred SPA OIR events. System is not impacted by this memory leak.

Workaround:

None.

Recovery:

No manual recovery is necessary. After several hundred OIR events the process gets automatically restarted without packet loss.

CSCsx17920

Basic Description:

Crashing mpls_ldp process does not trigger failover in NSR scenarios.

Symptom:

This issue occurs in rare circumstances when NSR is enabled and the NSR process-failure switchover configuration is added. This indicates that if any process (BGP, TCP, LDP) crashes and NSR sessions are up, RP failover is triggered as a means to recovery to keep NSR and sessions up.

Conditions:

This issue is seen on process crashes of mpls_ldp with core dump going to disk and the above configuration present if the core dump takes longer than 15 seconds (LDP discovery hold time).

Workaround:

When NSR is configured and the above process-failure configuration is present, turn off the core for LDP or dumping core to /tmp first.

process <mpls jid> core off

OR

process <mpls jid> core copy

Other option is to increase the LDP discovery hold time.

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 CRS-1 Router

The following caveats are specific to the Cisco CRS-1 platform:

CSCsl09040

Basic Description:

Bandwidth remaining 0% does not work as expected.

Symptom:

If a class has bandwidth remaining of 0% configured, that class may receive more bandwidth than the minimum bandwidth configured in that class.

Conditions:

This behavior is seen in classes with "bandwidth remaining percent 0" configured.

Workaround:

Configure shape bandwidth to be the same as minimum bandwidth of that class.

Important Notes:

The effect of the this is that the router does not allow a service-policy to be attached to an interface, if following two conditions occur:

1. It consists of a class with implicit or explicit value of "bandwidth remaining percent" equal to 0%.

2. No minimum bandwidth is configured for that class (using bandwidth command).

This behavior change was introduced in Cisco IOS XR Release 3.7.x with this caveat. Thus, customers with such configs need to modify their configs accordingly before upgrading to Cisco IOS XR Release 3.7.x to avoid any config failures.

To avoid this issue, if there is a class that has implicit bandwidth remaining percent equal to 0% for a class, then explicitly configure a non- zero value of bandwidth remaining percent. Or, change the values of bandwidth remaining percent in other classes to implicitly allocate a bandwidth remaining percent of non-zero value. Or, configure a minimum bandwidth using the bandwidth command.

CSCsm88362

Basic Description:

POS bundle statistics are inaccurate after member link is removed and re-added.

Symptom:

Removing and re-adding a member link from a POS bundle results in traffic statistics on the bundle interface being out of sync between opposite ends of the bundle. Egress statistics on the side where the change is made does not match corresponding ingress starts on the opposite end. However, total statistics on the physical links match opposite ends in both directions.

Conditions:

Remove link from bundle by either no bundle id on corresponding link configuration. Or, shutdown the physical link interface and then reverse operation to add the link back into the bundle.

Workaround:

None.

Recovery:

Remove all bundle members and add them back has been shown to work. Performing shut or no shut on the main bundle interface, on the side where the change is made, may restore accurate statistics.

Impact:

No impact on data forwarding over bundle, even though bundle statistics are no longer accurate at one end of bundle link. Statistics for individual links are ok.

CSCsr93937

Basic Description:

User Configured LPTS policer not properly applied after reload or LC OIR.

Symptom:

The LPTS hardware policer configurations are lost—for example, set to their default values and not the configured ones—after an OIR or reload.

Conditions:

This condition occurs after LC OIR or router reload, for example, lpts pifib hardware police location 0/2/CPU0 flow ospf multicast known rate 34. The above commands configure OSPF known multicast rate to 34 and on LC OIR or reload it resets to the defaults.

Workaround:

None.

Recovery:

After OIR or reload, reapply the LPTS hardware policer configuration manually.

CSCsv30843

Basic Description:

After failover, the standby RP copies software packages a second time.

Symptom:

Standby RP resyncs installed software packages a second time.

Conditions:

After upgrading from one release to another if a failover is done, before doing install commit, this issue is encountered.

Workaround:

Do install commit at the end of software installation or before doing a failover.

Recovery:

If you encounter this issue, the route processor resyncs the packages and becomes active again within an hour without user intervention.

CSCsw52814

Basic Description:

The install verify command reports errors that can be safely ignored.

Symptom:

The install verify command may detect anomalies on LCs (and maybe some RPs and DRPs) and output an error message: Info: /install/hfr-base-3.8.0/remote/lib/install_debug_remote: Info: exists with unexpected file size.

Conditions:

The install_debug_remote file on some RP or DRP nodes might be empty. In normal scenarios the file is a dummy file so the zero-length file problem actually has no any functional impact to the system.

Workaround:

None.

Recovery:

No recovery is necessary. The specific anomaly can be ignored.

CSCsx51681

Basic Description:

Unable to poll memory utilization with SNMP on named SDR routers.

Symptom:

CPU related OIDs for ENTITY-MIB, CISCO-PROCESS-MIB, and CISCO-ENHANCED-MEMORYPOOL-MIB on MSC line cards on a named SDR are not reported.

Conditions:

This symptom is observed on Cisco CRS-1 routers with the MSC line card hardware with Cisco IOS XR Software Release 3.8.0 where the MSC line cards are configured as a named SDR.

Workaround:

None.

The following CLI commands can be used to view the details not reported by the MIBs:

show platform

show process cpu location

show memory location

CSCsx57511

Basic Description:

No warning after QoS policy on new bundle member beyond HW scale.

Symptom:

Adding a bundle member to an existing bundle interface with QoS policy configured is committed successfully with no errors or warnings, but the bundle member is not correctly programmed with the existing QoS policy.

Conditions:

This scenario is encountered when the QoS policy hardware scale limit is reached, so the extra configured bundle member does not get the proper policy applied.

Workaround:

None. This represents a hardware scale limit.

CSCsy03777

Basic Description:

Power-disabled DRP causes much slower line-card boot time.

Symptom:

When the router comes up for the first time (meaning all nodes in the system are booting), the CPUs of any MSC (line card) take longer than normal to come up.

Conditions:

This occurs if there is a DRP CPU configured to be power-disabled (hw-module power disable location 0/6/cpu0) at router bootup. This does not happen with DRP SPs or any other card type.

Recovery:

LC comes up to IOS-XR ready state after approximately one hour without intervention.

Caveats Specific to the Cisco XR 12000 Series Router

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

CSCsx27983

Basic Description:

A 15 second delay resolving recursive routes after resolving route installed occurs.

Symptom:

On a router with scaled configuration, a failure message related to bcdl may be observed after clear cef linecard.

Conditions:

This is observed while testing the Cisco IOS XR Software Release 3.8.0 image on a router configured with Cisco IOS XR Software Release 3.8.0 scale (Profile 2) numbers.

Workaround:

None.

CSCsy08188

Basic Description:

Warning filesystem is not FAT32 message during boot time of Cisco IOS XR Software Release 3.8.0.

Symptom:

Warning filesystem is not FAT32 message may be displayed while the RP boots up.

Conditions:

This symptom is observed on a Cisco XR 12000 Series Router running Cisco IOS XR Software Release 3.8.0 software if the boot disk is formatted as FAT16 (which is default).

Workaround:

None.

Recovery:

It is safe to ignore this warning.

CSCsy19449

Basic Description:

IPv6 multicast VPN traffic drops following line card OIR.

Symptom:

IPv6 multicast VPN traffic may not be forwarded correctly following a line card OIR.

Conditions:

This issue was observed on a Cisco XR 12000 Series Router running Cisco IOS XR Software Release 3.8.0 following the OIR of a line card.

Workaround:

None.

Recovery:

Use the LC command clear mfib database on the customer-facing line card.

CSCsy24350

Basic Description:

Cisco 12410 chassis fail to properly recognize intelligent DC power supplies.

Symptom:

Cisco IOS XR Software Release 3.8.0 fails to detect the correct DC power supply for Cisco 12410 chassis.

Conditions:

This symptom is observed on a Cisco XR 12410 chassis with intelligent PEMs and the console displaying the following information:

RP/0/9/CPU0:ios(admin)# show environment power detail Fri Mar 6 12:32:35.972 UTC 
                    48V    Current
 R/S/I     Module   (V)      (A)

           PEM2     54        4            PWR-GSR10-AC= Standard AC PS

Workaround:

None at this time. This is a cosmetic issue. The power supplies function correctly.

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

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.

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

http://www.cisco.com/web/Cisco_IOS_XR_Software/index.html


Note Cisco IOS XR Software Release 3.8.0 requires a 2-GB Flash Disk as a minimum.
