In certain countries, use of these products might 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.
When upgrading a Cisco XR 12000 Series Router from Cisco IOS to Cisco IOS XR software, follow the upgrade instructions provided to minimize traffic impact. For detailed instructions, see the Upgrading from Cisco IOS to Cisco IOS XR Software on the Cisco 12000 Series Router, Release 3.2 document for procedures.
Follow the instructions we provide for all card removal and replacement (fabric cards, LC, fan controller and RP, and so on) to avoid impact to traffic. See Cisco IOS XR Getting Started Guide for procedures.
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:

As long as the Worst Case Redundant Power Available is not zero, a PEM can be powered down for replacement without impact.
Note
Caveats
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.
Resolved 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.
Workaround: none
•
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[133]: %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.
Workaround: none
•
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
Workaround: none
•
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.
Workaround: none
•
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:

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.
Workaround: none
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:
•
Platform-Independent Caveats
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.
Cisco CRS-1-Specific Caveats
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:

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.

Note
Submitting a Service Request
Using the online TAC Service Request Tool is the fastest way to open S3 and S4 service requests. (S3 and S4 service requests are those in which your network is minimally impaired or for which you require product information.) After you describe your situation, the TAC Service Request Tool provides recommended solutions. If your issue is not resolved using the recommended resources, your service request is assigned to a Cisco engineer. The TAC Service Request Tool is located at this URL:
http://www.cisco.com/techsupport/servicerequest
For S1 or S2 service requests or if you do not have Internet access, contact the Cisco TAC by telephone. (S1 or S2 service requests are those in which your production network is down or severely degraded.) Cisco engineers are assigned immediately to S1 and S2 service requests to help keep your business operations running smoothly.
To open a service request by telephone, use one of the following numbers:
Asia-Pacific: +61 2 8446 7411 (Australia: 1 800 805 227)
EMEA: +32 2 704 55 55
USA: 1 800 553-2447For a complete list of Cisco TAC contacts, go to this URL:
http://www.cisco.com/techsupport/contacts
Definitions of Service Request Severity
To ensure that all service requests are reported in a standard format, Cisco has defined these severities:
Severity 1 (S1)—Your network is down, or a critical impact to your business operations has occurred. You and Cisco commit all necessary resources around the clock to resolve the situation.
Severity 2 (S2)—Operation of an existing network is severely degraded, or significant aspects of your business operation are negatively affected by inadequate performance of Cisco products. You and Cisco commit full-time resources during normal business hours to resolve the situation.
Severity 3 (S3)—Operational performance of your network is impaired, but most business operations remain functional. You and Cisco commit resources during normal business hours to restore service to satisfactory levels.
Severity 4 (S4)—You require information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations.
