These release notes contain the following sections:
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 Routing—Supports a wide range of IPv4 and IPv6 services, and routing protocols, such as Border Gateway Protocol (BGP), Intermediate System-to-Intermediate System (IS-IS), Open Shortest Path First (OSPF), IP Multicast, Routing Policy Language (RPL), and Hot Standby Router Protocol (HSRP)/Virtual Router Redundancy Protocol features (VRRP).
•Bidirectional forwarding detection (BFD)—Provides low-overhead, short-duration detection of failures in the path between adjacent forwarding engines. BFD allows a single mechanism to be used for failure detection over any media and at any protocol layer, with a wide range of detection times and overhead. The fast detection of failures provides immediate reaction to failure in the event of a failed link or neighbor. OSPF, ISIS, BGP, and MPLS-TE FRR use BFD to detect failures. (CRS-1 only)
•MPLS—Supports Multiprotocol Label Switching (MPLS) protocols such as Traffic Engineering (TE), Resource Reservation Protocol (RSVP), and Label Distribution Protocol (LDP).
•Multicast—Provides comprehensive IP Multicast software including Source Specific Multicast (SSM). The Cisco CRS-1 platform supports Bidirectional Protocol Independent Multicast (BIDIR-PIM).
•Quality of service (QoS)—Supports rich QoS mechanisms including policing, marking, queuing, dropping, and shaping. Additionally, the operating systems support Modular QoS CLI (MQC). MQC is used to configure 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.
•Security—Provides comprehensive network security features including access control lists (ACLs), routing authentications, AAA/TACACS+, Secure Shell (SSH), SNMPv3, and leading Routing Policy Language (RPL) support. Control-plane protections integrated into line card ASICs include Generalized TTL Security Mechanism (GTSM), RFC 3682, and dynamic control plane protection.
•Craft Works Interface (CWI)—A client-side application used to configure and manage Cisco routers. The 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, and nonstop forwarding (NSF).
•In Service Software Upgrade (ISSU)—Supports a modular-packaging-based release model to minimize the impact of upgrades and supports ISSU with NSF, where possible.

If you intend to test beyond the combined maximum configuration tested and published by Cisco, contact your Cisco representative to discuss how to engineer a large-scale configuration maximum for your testing.
A Cisco SIP-600 LC draws more power than previous LCs. Depending on the configuration of power entry modules (PEMs) and other cards in the chassis, sufficient power might not be available when you insert a new card or remove a PEM. The show environment power-supply table command can help you plan the power budget for the chassis. Before inserting a new card (of any type) or removing a PEM, you should use the show environment power-supply table command, as in the following example:RP/0/0/CPU0:router# adminRP/0/0/CPU0:router(admin)#show env power-supply table48V Current R/S/I Module (V) (A) 0/24/* PEM1 46 12 PEM2 47 10 0/25/* PEM1 47 12 PEM2 47 10Total Power Supplies: 4800W Redundant Power Supplies: 2400W Worst Case Power Used: 1559W Current Power Used: 1022W Current Redundant Power Available: 1378W Current Total Power Available: 3778W Worst Case Redundant Power Available: 841W Worst Case Total Power Available: 3241WPID Description Watts --- ----------- ----- GRP-B Route Processor 38 PRP-1 Cisco 12000 Series Performance Route Processor 60 LC-4OC-3-POS-SM 4 Port Packet Over SONET OC-3c/STM-1 80 4OC3X/POS-MM-MJ-B 4 port ISE OC3 90 8OC3/POS-SM 8 Port Packet Over SONET OC-3c/STM-1 100 8OC3X/POS-MM-MJ-B 8 port ISE OC3 105 16OC3/POS-SM 16 Port Packet Over SONET OC-3c/STM-1 100 16OC3X/POS-M-MJ-B 16 port ISE OC3 channelized DS3/E3 140 LC-1OC12/POS-SM 1 Port OC12/STM4 Packet Over SONET/SDH Line Card 80 EOS. 4 Port E.D.

If you plan to insert a new card, locate the entry for the card to be inserted and note the power it consumes. If this power is less than the figure given in Worst Case Redundant Power Available (the figure 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. You are responsible for determining the power budget for the chassis before you change it. Exceeding the power budget can result in the PEM being overloaded and cards powering down due to insufficient available power.
Caveats describe unexpected behavior in Cisco IOS XR software. A severity 1 caveat is the most serious; a severity 2 caveat is less serious. This section lists resolved and open relevant caveats.
The following caveats from prior releases have been resolved in Cisco IOS XR Software Release 3.2.3.
Brief Description: cctl_server process exits after upgrade
Conditions: During an upgrade (release 3.2.x to 3.2.y), a cctl_server process crash might occur on a linecard. The upgrade completes successfully, and the process restarts.
Brief Description: Configuration commit list is deleted after a power cycle.
Symptoms: In rare circumstances, the configuration commit list is cleared after a system reload. The following error message is reported:
'cfgmgr-rp: %MGBL-CFGMGR-3-BOOT_ERROR: 'sysdb' detected the 'warning' condition 'A SysDB client tried to access a nonexistent item or list an empty directory'
Conditions: Configuration Manager was unable to use the previously saved commit points. All saved commit points in the commit database are removed.
Brief Description: SIP/SPA does not power up due to hardware or software error.
Symptoms: When a SPA is inserted into an active CRS1-SIP-800 Jacket card, if the onboard FPD image is down-rev compared to the FPD image bundled in the IOS XR image, a Syslog message is generated that indicates an upgrade is required. Performing this upgrade on SPAs or Jacket cards that have the new PROM hardware onboard would over-write the FPD images. The SPA subsequently fails with the same symptoms as D.O.A. hardware.
See the Field Notice at the following URL: http://www.cisco.com/en/US/partner/products/ps5763/products_field_notice09186a00805747e6.shtml
Brief Description: Wdsysmon detection algorithm improvement.
Conditions: WDsysmon is the process responsible for monitoring the behavior of processes within the system. This DDTS implements improvements in the CPUHog detection mechanism.
Brief Description: snmpd file descriptor leak with ipv4_rib
Symptoms: Following a system reload, a file descriptor leak might occur in the ipv4_rib process.
Conditions: The output of the sh process blocked command reports a number of processes that are blocked on ipv4_rib. For example:RP/0/RP1/CPU0:crs#sh processes blockedJid Pid Tid Name State Blocked-on65546 2031626 1 exec Reply 1 kernel350 69705 1 tftp_server Reply 8205 mqueue247 151714 2 lpts_fm Reply 151664 lpts_pa113 151727 3 bcdl_agent Mutex 151727-04 #1113 151727 4 bcdl_agent Reply 151688 ipv4_rib113 151727 6 bcdl_agent Reply 151688 ipv4_rib347 159923 7 tacacsd Reply 151698 tcp320 159924 1 snmpd Mutex 159924-02 #1320 159924 2 snmpd Reply 151688 ipv4_rib320 159924 4 snmpd Mutex 159924-02 #1361 168143 1 udp_snmpd Reply 151699 udp65766 2371814 1 show_processes Reply 1 kernel
Workaround: restart the snmpd process.
Brief Description: OpenSSL Security Advisory: Potential SSL 2.0 Rollback
This situation is addressed by the PSIRT notice at: http://www.cisco.com/warp/public/707/cisco-response-20051202-openssl.shtml
Brief Description: ping6: failed to get the receiving hop limit when a ping to linklocal IPv6 ping fails to link-local address.
Symptoms: An error "ping6: failed to get receiving hop limit" appears. An IPv6 ping to a directly connected neighbor's link-local address fails, but an IPv6 ping to the interface succeeds.
Conditions: This symptom occurs on routers with 3.2.2 IOS XR software configured with IPv6.
Open Caveats—Release 3.2.3
This section lists the open caveats for Cisco IOS XR Software Release 3.2.3. The caveats are organized as follows:
The following caveats apply to all platforms:
Brief Description: Internally found cosmetic defect: Reported % complete during the 'install add' command is inaccurate.
Symptoms: During the install add command operations, a window of 4-5 minutes might occur in which no status for the add operation appears on the terminal or console.
Conditions: This occurs only when performing the install add command operations.
Workaround: No workaround. Note that this does not impact the add operation. You should wait for the next install % (percentage) message to see the status of the install add command operations.
Basic Description: Removing and restoring configuration of address family can cause a BGP peer to remain down.
Symptom: IPv4 BGP neighbors do not come up after Address Family Identifier configuration is restored.
Conditions: If the address-family ipv4 is restored (for example, with rollback configuration) under router BGP approximately three minutes after the configuration was removed, the IPv4 BGP neighbors do not come back up.
Workaround: Restart the bgp process on the RP by using process restart bgp command.
Basic Description: An Optical User Network Interface (OUNI) connection goes down a few minutes after the Resource Reservation Protocol (RSVP) hellos come back up.
Symptom: On an RSVP hello control-channel failure, an OUNI connection may go down.
Conditions: The OUNI connection goes down if the control channel failure is detected by the passive side of the OUNI connection. This is because the passive side of the OUNI connection stops refreshing its RSVP state for the OUNI connection, and the active side eventually times out.
Workaround: After the RSVP hello control-channel failure on the passive side restart the RSVP process with process restart rsvp command.

The following caveats are specific to the Cisco CRS-1 platform:
Basic Description: On Cisco CRS-1/16 chassis, the show platform command shows UNKNOWN entry after multiple AM0/AM1 card OIRs.
Symptom: After performing more than 15-20 OIRs of the alarm card while it is in various stages of booting, show platform command shows an UNKNOWN entry.
Conditions: On Cisco CRS-1/16 chassis, if we do more than 15-20 OIRs of AM0 or AM1 while these nodes are booting (that is, in MBI-BOOT or MBI-RUN state), an UNKNOWN entry may eventually show up in the output of the show platform command.
Workaround: The process restart invmgr command fixes this problem.
Basic Description: Following a SPA OIR operation, an error may be encountered which results in subsequent packet loss. This can be corrected by restarting the affected SPA.
Symptom: The following error message is reported: %L2-BAMBI-3-ASIC_ERR: plaspa instance 0 L2P UIDB Multi, check uidb hash table. Data arriving on the affected SPA is dropped.
Conditions: This symptom is observed on Cisco CRS-1 routers Shared Port Adapters (SPA) during Online Insertion and Removal (OIR).
Workaround: Consider the following workaround:
–Power-down the affected SPA, wait 3 minutes, then power-up the SPA and check traffic flow.
–On-line insert and remove the affected SPA, wait 3 minutes, then reinsert SPA and check traffic flow.
–On-line insert and remove the SIP-800 housing of the affected SPA. This action must be a tertiary course because other in-service SPAs that are housed in the SIP-800 could be affected by this action.
Cisco XR 12000 Series Router-specific Caveats
The following caveats are specific to the Cisco XR 12000 Series Router platform:
Basic Description: TURBOBOOT (cold boot) procedure with the -clean option cleans all files on the boot disk (disk0:) of all non-DSC RPs.
Symptom: The TURBOBOOT procedure used with the -clean option cleans only the package files on the boot disk (typically disk0:) on the DSC. However on all other RPs in the system, all files on the boot disk are deleted (including any user or configuration files).
The configuration for non-owner LRs is stored on the boot device of the RPs of those LRs (not the DSC). If a turboboot is issued with the -clean option when LRs are carved out, this has the effect of deleting the configuration on any non-owner LRs.
Conditions: All package and user files on disk0: are deleted when TURBOBOOT starts on the non-DSC RPs.
Workaround: You should back up any configuration for non-owner LRs before starting the turboboot and re-apply this configuration manually when the turboboot has finished. Also, any other user files on the disk of any RP should be backed up before starting the turboboot.
Brief Description: Class or mark policy counters multiply. Counter multiplication depends on the number of match criteria.
Symptom: When a QoS policy uses a class map that classifies traffic based on a number of match-any criteria and this policy is applied to an interface in ingress or egress direction, the show policy map command counters can increment in the multiples of the number of match criteria.
Conditions: This condition is observed on the Cisco XR 12000 Series Router using QoS configurations involving class maps with multiple match criteria.
Workaround: No workaround.
Brief Description: Configuring APS in a router-to-router configuration may result in a PGP failure.
Symptom: Adding a working group and a protect group in a two-router topology may result in a PGP "no contact" failure between the newly configured groups.
Condition: The ipv4_rib_best_local_address command is returning 0 to aps.
Workaround: Remove the APS group configuration, followed by re-applying the configuration.
