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 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).
•
Multiprotocol Label Switching (MPLS)—Supports MPLS protocols, including 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 router 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), the routing authentications AAA and TACACS+, Secure Shell (SSH), and SNMPv3. Control plane protections integrated into line card ASICs include Global Time-to-Live Security Mechanism (GTSM), RFC 3682, and dynamic control plane protection (DCoPP).
•
Craft Works interface (CWI)—The CWI is 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. 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).

QoS has the following changes:
•
When QoS policies reference an ACL that contains an IPv4 source port, QoS now honors the IPv4 source port in the ACL.
•
For traffic shaping, the minimum bandwidth is raised from 128 kbps to 256 kbps when the bandwidth is explicitly specified (instead of specified as a percent). This minimum applies to the lowest possible amount in the bandwidth and shape average commands, and it applies to other values as an amount by which a value is rounded up. For example, 100 mbps is rounded up to the next higher multiple of 256 kbps.
•
For Cisco IOS XR Software Release 3.3.0 and later releases, a number of new units of measurement that have been introduced as options within the various Modular QoS command-line interface (MQC) can be applied within policy-maps.
Since the default units of measurement may no longer be the same, care must be taken when taking a configuration earlier than Cisco IOS XR Software Release 3.3.0 and applying it to Cisco IOS XR Software Release 3.3.0 or later. Table 7 lists the changes to QoS units of measurement.
Note
The default units of measurement (see Table 7) will be inserted into the QoS policy following the upgrade. This will result in a change to the policy's behavior. Therefore, manual review and keyword changes must be performed by the operator to ensure the policy operates as expected.
Keywords cannot be inserted into the running configuration on a router running Cisco IOS XR Release 3.2.x in advance of the upgrade. An option is to edit the configuration offline, and add the necessary keywords.
Note
To make change to a QoS policy, the policy must first be removed from any interfaces making a reference to it.
To remove a service policy from an input or output interface, use the no form of the service-policy command in interface configuration mode, as shown in the following syntax:
no service-policy {input | output}When the policy is removed from any interfaces, the edited policy is applied. Refer to the following Cisco IOS XR command reference sections:
–
Cisco IOS XR Modular Quality of Service Command Reference, Release 3.3
–
Cisco IOS XR Modular Quality of Service Command Reference, Release 3.4
Environmental Monitor
New traps for fans and power supplies will be generated.

New ROMMON Version
The ROM Monitor software must be upgraded to version 1.40 or higher on all RPs and other nodes on the router before a Cisco CRS-1 system is upgraded to Cisco IOS XR Software Release 3.3.1 or higher release. If the router is brought up with an incompatible version of the ROM Monitor software, then the standby RP or other nodes might fail to boot.
UDLD
Unidirectional link detection (UDLD) has been documented in Cisco IOS XR Getting Started Guide, Release 3.3 and in applicable sections of the multishelf documentation.
Features Specific to the Cisco XR 12000 Series Router
The following are new features in Cisco IOS XR Software Release 3.3.1 supported only on the Cisco XR 12000 Series Router platform:
•
Support for bidirectional forwarding detect (BFD) on the Cisco XR 12000 Series Router was added.
•
For E3 and E5, minimally disruptive restart (MDR) was added on the Cisco XR 12000 Series Router platform. The hw-module location command now has the keyword reload: hw-module location {node-id} reload {path | warm}

Important Notes
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 Upgrading from Cisco IOS to Cisco IOS XR Software on the Cisco 12000 Series Router, Release 3.3 for procedures.
Follow the instructions provided by Cisco for all card removal and replacement (fabric cards, line cards, 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 the 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.
Cisco SIP-600 line cards for the Cisco XR 12000 Series Router draw more power than previous line cards. Depending on the configuration of power entry modules (PEMs) and other cards in the system, sufficient power might not be available when a new card is inserted or a PEM is removed. Before you insert a new card or remove a PEM, run the environment show command in admin EXEC mode:
RP/0/0/CPU0:router# adminRP/0/0/CPU0:router(admin)# show environment power-supply table48V CurrentR/S/I Module (V) (A)0/24/* PEM1 54 4PEM2 53 40/25/* PEM1 54 4PEM2 53 4Total Power Supplies: 3200WRedundant Power Supplies: 1600WWorst Case Power Used: 621WCurrent Power Used: 428WCurrent Redundant Power Available: 1172WCurrent Total Power Available: 2772WWorst Case Redundant Power Available: 979WWorst Case Total Power Available: 2579WPID Description Watts--- ----------- -----GRP-B Route Processor 38PRP-1 Cisco 12000 Series Performance Route Processor 60LC-4OC-3-POS-SM 4 Port Packet Over SONET OC-3c/STM-1 804OC3X/POS-MM-MJ-B 4 port ISE OC3 90...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. Therefore, you must determine the power budget for the chassis before making any changes to it. Exceeding the power budget might result in the PEM being overloaded and cards powering down due to insufficient power availability.
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.
Open Caveats—Release 3.3.1
This section lists the caveats for Cisco IOS XR Software Release 3.3.1. They are organized as follows:
•
Caveats Specific to the Cisco CRS-1 Router
•
Caveats Specific to the Cisco XR 12000 Series Router
Platform-Independent Caveats
The following caveats apply to both platforms:
•
CSCsd93737
Basic Description: icmp-echo, icmp-pathecho operations were not created by the network management system.
Symptom: SNMP SET succeeds for non-udpEcho/jitter operations.
Conditions: When the router attempts set rttMonCtrlAdminVerifyData for operations with RttMonRttTypes other than udpEcho(5) and jitter (9), SNMP SET succeeds. This object is supported for only these two types of operations. Even when the SNMP SET shows success for unsupported operations, this object value is not set internally for them and, therefore, does not cause any functional impact.
Workaround: None
•
CSCse08168
Basic Description: After a reload, RADIUS does not find the source interface.
Symptom: The source interface does not seem to take effect upon reload or RP failover.
Conditions: This happens for software interfaces such as Loopback. Using physical interfaces does not appear to be a condition that causes the problem.
Workaround: Restart the RADIUS process.
•
CSCek39230
Basic Description: Unable to deactivate the MPLS PIE.
Symptom: Deactivation of the PIE fails.
Conditions: Under rare conditions, deactivation of the MPLS PIE fails. The root cause for this problem is still unknown.
Workaround: Try the deactivation process again.
•
CSCse41524
Basic Description: An SNMPD coredump occurs during the committing of the community.
Symptom: Process SNMPD fails when the community string is configured or during router reload with a startup configuration containing SNMP-specific configurations.
Conditions: Intermittent.
Workaround: Reapply the SNMP configurations.
After the message appears, the line card goes down:
%PLATFORM-SYSLDR-2-NETWORK_DOWN: slot 0: network connection down, reloadingConditions: The following sequence has triggered this line card restart:
1.
Load MGBL, MPLS, and MCAST PIEs.
2.
Load large configuration consisting of multicast, MPLS, VLAN, BGP and OSPF protocols.
3.
Run traffic.
4.
Run the commit replace command to empty the configuration.
Under rare conditions, the message in the symptom section might appear, and one or more line cards might reload.
Workaround: None at this time: the line card comes up without problems.
•
CSCek37462
Basic Description: Error in EXEC is seen during a ROMMON upgrade.
Symptom: An erroneous message appears: "Error in exec" during ROMMON upgrade.
Conditions: Format bootflash removes needed files on SP to upgrade ROMMON.
Workaround: None: This message can be safely ignored.
•
CSCek38913
Basic Description: The tftp_fs process fails.
Symptom: The tftp_fs process fails.
Conditions: This problem is seen only under rare conditions, and the trigger for it is not known.
Workaround: None. The system recovers on its own after the failure.
Caveats Specific to the Cisco CRS-1 Router
The following caveats are specific to the Cisco CRS-1 platform:
•
CSCsd39371
Basic Description: 10 GE requires shut/no shut after an online insertion and removal (OIR) of Xenpack.
Symptom: A TenGigabit interface might remain in a down/down state after the Xenpack goes through an OIR.
Conditions: This occurs on a 10-Gigabit Ethernet interface after OIR of the Xenpack.
Workaround: Issue a shutdown command and then a no shutdown command of the 10-Gigabit Ethernet interface.
•
CSCse38839
Basic Description: The FCC LED has incorrect LED status.
Symptom: Some of the bundles have the wrong LED status on the FCC LED Module even though all the fabric functionality is working fine.
Conditions: Occurs only in a multishelf system.
Workaround: None.
Caveats Specific to the Cisco XR 12000 Series Router
The following caveats are specific to the Cisco XR 12000 Series Router platform:
None.
Upgrading Cisco IOS XR Software
Cisco IOS XR software is installed and activated as modular packages, allowing specific features or software patches to be installed, upgraded, or downgraded without impacting unrelated processes. Software packages can be upgraded or downgraded on all supported card types, or on a single card (node). Cisco IOS XR software packages are installed from package installation envelopes (PIE) files that contain one or more software components.
The following URLs link to online information that describes how to upgrade or downgrade Cisco IOS XR software from Release 3.2 or EFT/Beta versions of Release 3.3 to the FCS version of Release 3.3.0.
To upgrade the software on the Cisco CRS-1 Router, go to:
http://www.cisco.com/cgi-bin/tablebuild.pl/crs1upgrade
Select "CRS-1_Upgrade_Procedure_3.2.x_to_3.3.0.htm" to upgrade from Release 3.2.x release, and select "CRS-1_Upgrade_Procedure_EFT-BETA_to_3.3.0.htm" to upgrade from an early field trial (EFT) or Beta release to Release 3.3.0.
To upgrade the software on the Cisco XR 12000 Series Router, go to:
http://www.cisco.com/cgi-bin/tablebuild.pl/c12000upgrade
Select "XR12000_Upgrade_Procedure_3.2.x_to_3.3.0.htm" to upgrade from Release 3.2.x release, and select "XR12000_Upgrade_Procedure_EFT-BETA_to_3.3.0.htm" to upgrade from an early field trial (EFT) or Beta release to Release 3.3.0.
Note
Before you install or upgrade the software, first upgrade the ROM Monitor software to the correct version. If a Cisco CRS-1 system running Cisco IOS XR software release 3.3.0 is brought up with the incorrect ROM Monitor software, the standby RP fails to boot and an error message appears. To address this issue in a single-shelf router, refer to the "Upgrading and Downgrading ROM Monitor Software on Cisco CRS-1 Routers" chapter of Cisco IOS XR ROM Monitor Guide.
Turbobooting PRP Cards
This section contains instructions for turbobooting the PRP cards. The first series of steps apply when disk0: is the target. Instructions for using compact flash as the target come after these steps.
Note
1-GB compact flash is supported only with Cisco IOS XR software version 3.3.0 and later. Therefore, if you are upgrading from a release prior to 3.3.0, you must continue to use disk0.
In the current release, only the FLASH-PRP2-1G compact flash is supported.
Turbobooting to Disk0:
Take the following steps when disk0: is the target.
Step 1
Boot the DCS RP with the composite image:
rommon> confreg 0x0rommon> resetrommon> unset BOOTrommon> TURBOBOOT=on,disk0rommon> syncrommon> boot tftp://../c12k-mini.vm-3.3.1The confreg step ensures that ROMMON does not autoboot from previously installed software.
The following line shows TURBOBOOT ROMMON variable usage:
TURBOBOOT=option1, option2, ...
Available options:
For example:
rommon> TURBOBOOT=on,disk0,formatrommon> syncStep 2
Without waiting, netboot all other RPs with the MBI:
rommon> unset TURBOBOOTrommon> unset BOOTrommon> syncrommon> boot tftp://../mbiprp-rp.vm-3.3.1
Note
The TURBOBOOT variable should not be set on other RPs.
Step 3
Wait for the Turboboot process to finish (approximately 30 minutes).
•
The DSC netboots (image is loaded in memory).
•
Target boot devices are cleaned and formatted (depending on the TURBOBOOT option).
•
Software is copied from memory to the target boot device.
•
All RPs that are found in MBI running state by the DCS are turbobooted.
•
ROMMON variables (confreg and BOOT) are set appropriately.
•
When all cards are done, the DCS resets and reloads the software from disk.
•
All other RP cards self-reset and reload from disk.
Turbobooting to Compact Flash
The steps in this section apply to turbobooting to compact flash.
Note
1-GB compact flash is supported only with Cisco IOS XR software version 3.3.0 and later. Therefore, if you are upgrading from a release prior to 3.3.0, you must continue to use disk0.
In the current release, only the FLASH-PRP2-1G compact flash is supported.
Step 1
Boot the DCS RP with the composite image:
rommon> confreg 0x0rommon> resetrommon> unset BOOTrommon> TURBOBOOT=on,compactflashrommon> IOX_CONFIG_MEDIUM=compactflash:/config/rommon> syncrommon> boot tftp://../c12k-mini.vm-3.3.1Step 2
Without waiting, netboot all other RPs with the MBI:
rommon> unset TURBOBOOTrommon> unset BOOTrommon> IOX_CONFIG_MEDIUM=compactflash:/config/rommon> syncrommon> boot tftp://../mbiprp-rp.vm-3.3.1
Note
The TURBOBOOT variable should not be set on other RPs.
Step 3
Wait for the Turboboot process to finish (approximately 30 minutes).
•
The DSC netboots (image is loaded in memory).
•
Target boot devices are cleaned and formatted (depending on the TURBOBOOT option).
•
Software is copied from memory to the target boot device.
•
All RPs that are found in MBI Running state by the DCS are turbobooted.
•
ROMMON variables (confreg and BOOT) are set appropriately.
•
When all cards are done, the DCS resets and reloads the software from the disk.
•
All other RP cards self-reset and reload from disk.
Installing Optional Packages
The events in Step 3 in the preceding section must occur before you begin the steps in this section.
Note
All installation commands must be performed in admin EXEC mode.
Note
If the system was turbobooted to compactflash:, disk0: will show compactflash:.
.
Action/Description Sample CommandsInstall optional packages.
RP/0/0/CPU0(admin)# install add tftp://../c12k-mpls.pie-3.3.1RP/0/0/CPU0(admin)# install activate disk0:/c12k-mpls-3.3.1
For automated execution, we recommend that you use the synchronous option for all package/PIE activation or deactivation commands. This approach ensures that the console prompt does not come back up until the system finishes the package/PIE activations or deactivations.
