Introduction
Cisco IOS XR software is a distributed operating system that provides the following features:
•
IP and Routing—Supports a wide range of IPv4 and IPv6 services, and routing protocols; such as Border Gateway Protocol (BGP), Routing Information Protocol (RIP), 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), Label Distribution Protocol (LDP), Layer 2 virtual private network (L2VPN), and Layer 3 VPN (L3VPN).
•
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 command-line interface (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; authentication, authorization, and accounting (AAA)/Terminal Access Controller Access Control System (TACACS+); Secure Shell (SSH); and Simple Network Management Protocol Versions 3 (SNMPv3). 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)—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. 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).
For a detailed list of new features by platform for Cisco IOS XR software for the current release, see the "New and Changed Information" section.
Cautions
Carefully observe all applicable safety procedures and warnings when dealing with potential hazardous energy sources.
CautionHazardous energy may still be present when a DC FAIL alarm is active. The console message of Low or No Input Voltage detected is generated when voltage reaches 40 volts +/- 1 volt. The command show-env-power is inaccurate at that voltage level and may show 0.0 for the readings. Before performing any maintenance, measure Battery and Return with a volt ohm meter on all failed PEMS.

New and Changed Information
Cisco IOS XR Software Release 3.4.3 is a maintenance release only. Therefore, no new software or hardware features are being introduced.
Note
For the Routing Policy Enhancements, SIP TLS, and SIP Outbound Authentication features, contact your Cisco SE for scale information.
See the following documents for detailed information on the shared port adapters (SPAs) and SPA interface processors (SIPs):
•
Cisco XR 12000 Series Router SIP and SPA Hardware Installation Guide, Release 3.4.0
•
Cisco IOS XR Interface and Hardware Component Configuration Guide, Release 3.4.0
Important Notes
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.
When migrating from Cisco IOS to Cisco IOS XR software on a Cisco XR 12000 Series Router, follow the migration instructions provided to minimize traffic impact. For detailed procedures, see the document Upgrading from Cisco IOS to Cisco IOS XR Software on the Cisco 12000 Series Router.
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. For more information, see the Cisco IOS XR Getting Started Guide.
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.
Cisco SIP-600 line cards (for the Cisco XR 12000 Series Router) 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.
Before you insert a new card or remove a PEM, run the following command in admin mode:
RP/0/0/CPU0:router# adminRP/0/0/CPU0:router# 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 off 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.
Note
When using the HW-Module location all reload command, VLAN ARP is not resolved, and pings on 5-port Ethernet SPA fails. To resolve this issue, load SMU (CSCsj33183), which is available at http://www.cisco.com/pcgi-bin/tablebuild.pl/iosxr-smu.
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.
This section lists the caveats for Cisco IOS XR Software Release 3.4.3. The caveats are organized as follows:
•
Quality of Service Units of Measure Changes
•
Caveats Specific to Cisco CRS-1
•
Caveats Specific to Cisco XR 12000 Series Router
Quality of Service Units of Measure Changes
Because the default units of measure 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 6 lists the changes to Quality of Service (QoS) units of measure.
Note
The default units of measure (see Table 6) 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. See 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
Platform-Independent Caveats
The following caveats apply to both Cisco CRS-1 and Cisco XR 12000 Series Routers:
Note
Secure domain routers should be configured with lowercase letters in order for specific installation operations to succeed. For more information, see the Cisco IOS XR Getting Started Guide, Release 3.4 on www.cisco.com.

CSCsk59453
Basic Description:
The chkpt_proxy process crashed after OSPF unconfig/rollback.
Conditions:
In some cases, an ospf chkpt_proxy terminates due to an OSPF uncofig/rollback.
Symptom:
The chkpt_proxy process is terminated for OSPF. No visible effect on the router.
Workaround:
None. Functionality impact is minimal, because after its termination, the chkpt_proxy restarts and resyncs all essential information from its parent process on the active RP.

CSCse83983
Basic Description:
A tunnel does NOT go down and come up on topo change in non-head area.
Symptom:
When IOS XR Release 3.4 MPLS Traffic Engineering node is a non-head area node and there is a topology change triggered either due to IGP link add/removal or any other topology change in the IGP (say) Level 1 to Level 2 for the links on that node. The inter-area tunnels originating from the Head and going via that link will NOT flap as a result of this topology change.
Conditions:
This behavior is seen in IOS XR Release 3.4 in a non-head area node and inter-area TE tunnel is being setup with loose hop in the path ERO.
Additional Notes:
Path verification and tunnel reoptimization indication are not done by the midpt ABR node. This is similar to the IOS behavior today. This feature will be added in a future release.
Workaround:
None.

CSCse97786
Basic Description:
L2VPN: Control Word cannot be set if pseudowire (PW) is established with cbit=0
Symptom:
Router not sending Control Word even when Control Word is enabled.
Conditions:
If a PW is established with cbit=0, and later using config we enabled control word or if neighbor sends a label mapping with control word cbit=1, Cisco IOS XR will still send cbit=0.
Workaround:
The workaround is to delete and reconfigure the PW on both the PEs.
•

Basic Description:
L2VPN: Support destination with Rtg ID different than LDP rtr ID.
Symptom:
Cannot establish PW to a non-LDP router ID address.
Conditions:
PW can be established on to the LDP router ID. Currently, Cisco IOS XR does not support PW to non-LDP router IDs.
Workaround:
None.

Basic Description:
Command show mpls lsd forwarding displays invalid format_tbl:136.
Symptom:
Command show mpls lsd forwarding displays invalid format_tbl:136.
Conditions:
Under normal scenarios.
Workaround:
There is no workaround for this as of now.
Caveats Specific to Cisco CRS-1
The following caveats are specific to the Cisco CRS-1 platform:
•
CSCsg18108
Basic Description:
Netio process restarts when trying to restore configuration from disk.
Symptom:
An unexpected netio process termination may occur when trying to restore configuration from disk or when changing the encapsulation of an interface from ppp to hdlc and vice versa.
Condition1: If the router has POS or serial interfaces and the configuration is cleared the following command and then restored back from disk, the netio process may terminate:
–
commit replace
–
yes
–
end
Condition 2: If the encapsulation of a serial interface is changed repeatedly from ppp to hdlc and vice versa, and if the packets are being sent out of that interface at the same time, the netio process may terminate.
Workaround:
Workaround for Condition 1: When loading the configuration from disk, make sure the POS and serial interfaces are in a shut-down state. Once the configuration is loaded, the interfaces can be enabled again.
Workaround for Condition 2: If there is a need to change the encaps of a serial or POS interface, shut the interface before changing the encapsulation. The interface can be enabled after the configuration change has been made.

Basic Description:
Line protocol state for SONET controller should be admin-down after LC reload.
Symptom:
When shutting down the SONET controller, Intf/LineP state shown in show controllers sonet should be admin-down/admin-down. However, LineP goes to the down state after LC reload.
Conditions:
Occurs after the LC reload.
Workaround:
Perform the no shutdown command on the controller, and then perform the shutdown again to clear the state.

•
CSCsj10619
Basic Description:
Garbled character of authentication string on entering show vrrp detail command.
Symptom:
The last portion of the string value for show vrrp detail command is garbled.
Conditions:
When the eight alphanumeric characters are used by authentication string for VRRP.
Workaround:
None. The string value of show vrrp detail command is normal when the alphanumeric characters from one to seven are used for authentication.
Caveats Specific to Cisco XR 12000 Series Router

•
CSCsk20479
Basic Description:
vty-pool config timeout messages appear after reload.
Symptoms:
On reboot or during a commit of a configuration change, the following pair of messages may appear:
sysdb_svr_shared[596]: %SYSDB-SYSDB-7-TIMEOUT_APPLY : Apply callback for 'cfg/gl/vty/pools/default' from 'cfgmgr-rp' (jid 180, node 0/10/CPU0). No response from 'devc-vty' (jid 193, node 0/10/CPU0) within the timeout period (120 seconds), system may now be in an inconsistent statesysdb_mc[593]: %SYSDB-SMC-7-TIMEOUT : Message #2011, destined for shared plane, timed out having received 0 of 1 expected responses: returning error to client cfgmgr-rp. Check for potential transport issues within the system, or deadlocked SysDB processes.Conditions:
The problem is seen when the startup configuration, or the configuration change being committed, contains vty-pool configuration items.
Workaround:
If the problem is seen during startup, no workaround is required. The vty-pool configuration should be present in the running configuration. To verify this, use the show running-config command.
If the problem is seen during a commit, also use the show running-config command to verify whether or not the committed configuration is present.
If it is not present, repeat the commit of the vty-pool commands, this time using the best-effort option in conjunction with the commit command.
Finally, run the cfs check command to re-synchronize the persistent configuration on disk with the running configuration.
