New Software Features in Cisco IOS XR Software Release 3.2.1
The following are new features in Cisco IOS XR Software Release 3.2.1 supported on the Cisco CRS-1 and Cisco XR 12000 Series Router platforms:
•
alias alias-name command-syntax [(variable)]The alias command syntax is describe in Table 7:
Multiple commands can be supported under a single command alias, and multiple variable can be supported for each command. If multiple commands are specified under a single alias, then each command is executed in the order in which it is listed in the alias command.
To specify multiple commands under a single command alias, include the
command-syntax [(variable)] argument multiple times after alias alias-name argument, as show in the following example:alias alias-name command-syntax [(variable)] command-syntax [(variable)] command-syntax [(variable)]
To delete an alias, use the no form of this command, as shown in the following example:
no alias alias-name command-syntaxThe following example shows how to configure the show interface pos and show controller sonet commands with the intf keyword under the alias show_intf:

The following example shows how to enable link and line-protocol state change messages:
RP/0/0/CPU0:router(config-if)# logging events link-statusThe following example shows how to disable link and line-protocol state change messages:
RP/0/0/CPU0:router(config-if)# no logging events link-status•
Prior to Release 3.2.1, MPLS and IP populated load-balance (LB) tables based on the information from the LDP routing plane without consulting with the platform. For example if route has two paths, then MPLS will populate the LB table with two entries for this route.Changed Software Features in Cisco IOS XR Software Release 3.2.1
The following features were modified in Cisco IOS XR Software Release 3.2.1, and are supported on the Cisco CRS-1 and Cisco XR 12000 Series Router platforms:
•
The following example illustrates the correct usage of the admin command. In this example, the user executes the show running command from Admin mode by enter the admin command in EXEC mode, followed by the show running command in Admin mode:
RP/0/RP0/CPU0:router# adminRP/0/RP0/CPU0:router(admin)# show runningThe following example illustrates incorrect usage of the admin command. In this example, the user executes the show running command from EXEC mode by prefixing the show running command with admin keyword:
RP/0/RP0/CPU0:router# admin show running ^ % Invalid input detected at '^' marker.Important Notes

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 provided by Cisco for all card removal and replacement (fabric cards, LC, fan controller and RP, and so on) to avoid impact to traffic. See the Cisco IOS XR Getting Started Guide for procedures.
If you intend to test beyond combined maximum configuration tested and published by Cisco, please contact your Cisco representative to discuss how to engineer a large-scale configuration maximum for your testing.
The Cisco SIP-600 line cards draw more power than previous 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. The admin command show environment power-supply table helps plan the power budget for the chassis. Before inserting a new card (of any type, not just a line card) or removing a PEM, execute the following commands:

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 releases. Severity 1 caveats are the most serious caveats; severity 2 caveats are less serious.
Release 3.2.0 Caveats Resolved in Release 3.2.1
This section lists the caveats from Cisco IOS XRSoftware Release 3.2.0 that were resolved in Cisco IOS XR Software Release 3.2.1.
•
Basic Description: LDP installing "Unlabelled" as outgoing labels for prefixes over tunnel-te interface after RP Failover is performed.
Symptom: The traffic is not taking LDP label after RP Fail Over (FO) because prefixes pointing to a tunnel-te interface are marked as Unlabelled in show mpls forwarding.
Furthermore, LDP targeted session over tunnel-te interface does not seem to come up.
Conditions: When MPLS LDP is enabled on a tunnel-te interface and prefixes are learned over that tunnel-te interface with autoroute announce, labels are assigned to these prefixes pointing to the tunnel-te interface. After an RP switchover, these prefixes are marked as "Unlabelled."
Workaround: Restart the mpls_ldp process with process restart mpls_ldp.
•
Basic Description: On a Cisco CRS-1-8 RP chassis, show environment fans returns "0 rpm" for all fans if RP1 is active and RP0 is standby.
Symptom: On a Cisco CRS-1-8 RP chassis, if RP1 is active RP and RP0 is booted and in IOS XR RUN state, then show env fans will return "0 rpm" for all fans, even though the fans are spinning. Also, show environment leds will return UNKNOWN for the status of the fan-tray LED even though the LEDs are green (i.e. OK state).
Conditions: This problem can occur on any Cisco CRS-1-8 testbed which has 2 RPs, with RP1 as the active RP and RP0 in IOS XR RUN state.
Workaround: The workaround is to run the show environment fans command from RP0 always on CRS-8 chassis.
•
Basic Description: IPV4 Multicast is not supported on SIP-600 Engine 5 Line card.
Symptom: IPV4 Multicast is not supported on SIP-600 Engine 5 Line card.
Conditions: IPV4 Multicast is not supported on SIP-600 Engine 5 Line card.
Workaround: Use IPV4 Multicast on Engine 3 Line Card.
•
Basic Description: An invalid boothelper message displayed upon installing IOS XR when bootflash does not have requisite boothelper file.
Symptom: Install Director raises PKG_PLAT-4-INVALID_BOOTHELPER_VERSION warning message indicating the absence of a valid boothelper message. The device will continue to boot.
Conditions: If Install Director cannot find a boothelper file with named "c12kprp-boot-mz.120-30.S" or "c12kprp-boot-mz.120-29.2.S" on bootflash, it raises PKG_PLAT-4-INVALID_BOOTHELPER_VERSION warning message. Please note that the supported boothelper version is 12.0(30)S and Install Director's check is out of date.
Workaround: If the device already has the correct boothelper version, you can either ignore this warning message or make sure that the filename of the boothelper is either "c12kprp-boot-mz.120-30.S" or "c12kprp-boot-mz.120-29.2.S."
Open Caveats—Release 3.2.1
This section lists the open caveats for Cisco IOS XR Software Release 3.2.1. The caveats are organized as follows:
Platform-Independent Caveats
The following caveats apply to all platforms:
•
Basic Description: TURBOBOOT (cold boot) procedure with -clean option cleans all files on boot disk (disk0:) of all non-DSC RPs.
Symptom: The TURBOBOOT procedure used with the clean option will clean 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 will be deleted (including any user or configuration files).
The configuration for non-owner LRs is stored on the boot device of those LRs' RPs (not the DSC). So if a turboboot is issued with the clean option when LRs are carved out this will have the effect of deleting the configuration on any non-owner LRs.
Conditions: All package and user files on disk0: are deleted when easybake starts on the non-DSC RPs.
Workaround: The user should backup any configuration for non-owner LRs before starting the turboboot and re-apply this configuration manually once the turboboot has completed. Also, any other user files on the disk of any RP should be backed up before starting the turboboot.
•
Basic Description: Unconfig/reconfig of address family can cause BGP peer to remain down.
Symptom: IPV4 BGP neighbors do not come up after AFI config is restored.
Conditions: If the address family ipv4 is restored (config rollback) under router bgp ~3 min after the cfg was removed, the ipv4 bgp neighbors do not come back up.
Workaround: Restart the BGP process on the RP.
•
Basic Description: This happens when FO is triggered with a heavy load on the systems:
many BGP/IGP routes and 1000s of tunnels. In this case, the FO goes awry and MPLS-TE might have the wrong labels installed in forwarding. This would cause forwarding over those tunnels to be broken. The solution is to restart te_control after the FO is done.
Symptom: Forwarding over TE tunnels may stop.
Conditions: With a heavy load, and after RP failover.
Workaround: Restart te_control process restart te_control.
•
Basic Description: The OUNI connection goes down a few minutes after the RSVP Hellos come back up. 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.
Symptom: On an Resource Reservation Protocol (RSVP) Hello control channel failure, an OUNI (Optical User Network Interface) 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.
Workaround: After the RSVP Hello control channel failure on the passive side, restart the RSVP process.
Cisco CRS-1-specific Caveats
The following caveats are specific to the Cisco CRS-1 platform:
•
Basic Description: On Cisco CRS-1-16 chassis, show hfr 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, sh hfr shows up an UNKNOWN entry.
Conditions: On a Cisco CRS-1-16 chassis, if we do more than 15-20 OIRs of AM0 or AM1 while these nodes are booting (i.e. in MBI-BOOT or MBI-RUN state), we may eventually see an UNKNOWN entry show up in the output of show hfr.
Workaround: process restart invmgr fixes this problem.
•
Basic Description: The error message in this DDTS is indicating that the uidb table in PLIM ASIC is inconsistent. There is a TCAM lookup in the uidb table for each packet passing through the PLIM ASIC to determine the uidb and other fields that need to be set in ingress PLIM header.
