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), 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).

See the "New and Changed Information" section for a detailed list of new features by platform for Cisco IOS XR Software Release 3.4.0.

•Carrier Supporting Carrier (CSC)—Allows an MPLS VPN service provider to connect geographically isolated sites using another backbone service provider and still maintain a private address space for its customer VPNs. Based on IETF RFC 4364.

•IP Service Level Agreement (SLA)—Performs active monitoring by generating and analyzing traffic to measure performance, either among routers or from the router or from a router to a remote IP device such as a network application server. Measurement statistics (provided by IP SLA operations) are used for troubleshooting, problem analysis, and designing network topologies. This feature is derived from the technology previously known as Service Assurance Agent (SAA). Cisco IOS XR enhancements include:

–Support for UDP Echo, Internet Control Message Protocol (ICMP) Echo, User Datagram Protocol (UDP) Jitter, ICMP Path Echo and ICMP Path Jitter in VRF context.

–Label Switched Path (LSP) Ping and LSP Trace Route Operations for MPLS VPN Monitoring and Diagnosis

•DHCPv4 Option 82 and DHCPv6 support:

–DHCPv4 Option 82—Allows for a Relay Agent to pass DHCP messages between the DHCP clients and DHCP servers. DHCP Option 82, Relay Agent Information, was introduced in RFC 3046 to address security and scalability issues in public use. The remote ID and circuit ID sub-options are supported in this release.

–DHCPv6—DHCPv6 performs the same address assignment and host configuration functions for IPv6 as DHCPv4 does for IPv4. DHCPv6 is based on IETF RFC 3315.

•Craft Works Interface (CWI)—Allows administrators to manage, monitor, and configure a single device or a network of devices. CWI Enhancements include:

–JAVA Runtime Environment (JRE) v1.5 support

–Scripted login

–Per SDR software management (install, activate, deactivate, commit)

–Per SDR software rollback

•Border Gateway Protocol (BGP) authentication key chaining—Provides the following BGP enhancements for authentication key chaining:

–Hitless key lifetime and graceful rollover (using accept-lifetime and send-lifetime)

–Key-string encryption

–Key acceptance tolerance

–Authentication algorithm support for Message Digest 5. (MD5), Secure Hash Algorithm 1 (SHA1), Hash Message Authentication Code SHA1 (HMAC-SHA1), or HMAC-MD5

•BGP 4-Byte ASN—Increases the range of supported autonomous systems from 2 bytes to 4 bytes to scale with expected Internet growth.

•BGP next-hop tracking—Provides the following enhancements:

–New show command to see next hops used by various BGP tables and state associated with each next hop entry

–New reset command to reset the next hop cache entries.

–Support for two-level trigger delay for critical and non-critical next hop change events.

–Support for policy-based filtering for the next hops.

–Routing Policy Language (RPL) policy-based filtering based on source protocol and prefix and prefix-length. This filtering helps to avoid resolving Next Hops over some aggregate routes.

–BGP IETF RFC 4273 BGP4-Management Information Base (MIB) enhancement to support reflect neighbor indexing.

–BGP MIB MIBv2 draft-ietf-idr-bgp4-mibv2-05.txt.

•Bidirectional Forwarding Detection (BFD) to aid Protocol Independent Multicast (PIM) in subsecond detection of failures between adjacent systems; uses BFD functionality to enable scalable subsecond fault detection for PIM.

•MT-ISIS—Enables the Intermediate System-Intermediate System (IS-IS) IPv4 multicast address family in IS-IS, which allows for a multicast topology that is independent of the unicast topology created by IS-IS.

•TE Forwarding Adjacency Support for IS-IS and OSPF—Adds support for TE Forwarding Adjacency (FA) for IS-IS and OSPF routing protocols. Forwarding Adjacency is described in IETF RFC 4206.

The forwarding adjacency feature provides a way to aggregate Label Switched Paths (LSPs) by creating a hierarchy of such LSPs. First a label switching router (LSR) creates a traffic engineering label switched path (TE LSP) and the LSR forms a forwarding adjacency (FA) for that LSP by announcing the LSP as a TE link into IS-IS/Open Shortest Path First (OSPF). Other LSRs can then use the FA for their path computation.

•MPLS TE enhancements—Enhances the Cisco IOS XR MPLS Traffic Engineering (TE) feature set:

Multiarea/instances:

–Support TE configurations in multiple OSPF areas or IS-IS instances

–Support for TE topology and tunnel setup in multiple OSPF areas or IS-IS instances

–Link record advertisement for multiple OSPF areas or IS-IS instances

–Handle multiple TE router IDs

Interarea TE:

–Support for loose hop configuration in Explicit Path

–Support for loose hop ERO expansion

–Checkpoint expanded ERO and path setup information at midpoint.

Interarea TE reoptimization:

–Support for reoptimization query from tunnel head

–Reoptimization query at midpoint

–Support for new path error at head and midpoint

Fast ReRoute (FRR):

–Insert node ID sub-object in Record Route Object (RRO)

–Use node ID sub-object from RRO for FRR backup assignment

TE link coloring

–Support for global color-name to value mapping

–Support for assigning link colors using the new style

–Support for four types of color constraints under TE tunnel (include, exclude, include-strict, exclude-all)

•Addition of new MIBS:

–CISCO-IETF-PW-TC-MIB

–CISCO-IETF-PW-MIB

–CISCO-IETF-PW-ENET-MIB

–CISCO-IETF-PW-MPLS-MIB

–TCP/UDP MIB

–OSPF-TRAP-MIB

–NOTIFICATION-LOG-MIB

–CISCO-IP-STAT-MIB

•The following MIBS have been enhanced:

–CISCO-RTTMON-MIB

–ENTITY-MIB

–IF-MIB

Cisco CRS-1 Specific Features

The following are new features in Cisco IOS XR Software Release 3.4.0 supported only on the Cisco CRS-1 platform:

•MPLS VPN Inter-Autonomous System (AS)—Enables a VPN service provider network to exchange IPv4 routes with MPLS labels. Using Inter-AS, a local provider edge (PE) router must know the routes and label information for the remote PE router. This information can be exchanged between the PE routers and autonomous system boundary routers (ASBRs) in one of the following ways:

–The ASBR can redistribute the IPv4 routes and MPLS labels that it learned from EBGP into IGP and LDP, and vice versa.

–The ASBR and provider edge (PE) router can use direct iBGP sessions to exchange VPNv4 and IPv4 routes and MPLS labels.

•CRS-1 IPv6 link bundling support—Provides support for IPv6 over both Packet over SONET/SDH (POS) and Ethernet link bundling

•IPv6 BGP Policy Accounting—Allows per-interface accounting of ingress or egress IP traffic-based on AS number, AS-path, community-list. The BGP table-policy command is used to classify the prefixes BGP puts into the routing table according to routing policies based on AS number, AS-path, and community list. Based on the routing policy, BGP policy accounting assigns each prefix a bucket associated with an interface.

•Packet time to live (TTL) filter access control list (ACL)—Enables packet classification and filtering based on the TTL field of the IP header for IPv4 packets or Hop Limit field of the IP header for IPv6 packets. This is supported on all interfaces and in both ingress and egress directions.

•VLAN Attachment Circuit Type support

•Ethernet Interworking

•The following new MIBS are added:

–CISCO-RF-MIB

–CISCO-IF-EXTENSION-MIB

•Quality of Service (QoS) units of measurement changes—Provides support for a number of new units of measurement that have been introduced as options within the various Modular QoS command-line interface (MQC) that are applied within policy-maps for Cisco IOS XR Software Release 3.3.0 and later releases.

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.

Table 7 Changes to Quality of Service Units of Measurement 

Command	Cisco IOS XR Release 3.2 (Default)	Cisco IOS XR Release 3.3.x and Cisco IOS XR Release 3.4.x (Default)
bandwidth	kbps	kbps
police rate	kbps	bps (change)
queue-limit	bytes	packets (change)
random-detect	bytes	packets (change)
shape average	kbps	packets (change)

---

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

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 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# admin

RP/0/0/CPU0:router# show environment power-supply table

                      48V       Current

.

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. 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.

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 3.4.0

This section lists the caveats for Cisco IOS XR Software Release 3.4.0. The caveats are organized as follows:

•Platform-Independent Caveats

•Cisco CRS-1-specific Caveats

•Cisco XR 12000 Series Router-specific Caveats

Platform-Independent Caveats

The following caveats apply to both platforms:

•CSCsg12719

Basic Description:

Configuration commits fail due to missing vinfo directory after RP failover

Symptom:

After a failover, configuration commits may fail with the following error message:

% Failed to commit. As an error (Unknown) encountered during commit operation. Changes 
may not have been committed: No such file or directory 

Also, the configuration version files on disk0 will be missing. To check if this is the case, run the following commands:

cd /disk0:/config/running/vinfo 

dir 

If you're encountering the same issue, the "vinfo" directory will be empty.

Conditions:

This issue can occur in IOS XR Release 3.3.2 and higher.

Workaround:

Running clear configuration inconsistency will rebuild the configuration file system, and enable config commits to proceed. This command may need to be run from both the LR exec prompt and the admin exec prompt.

Further Problem Description:

This is a rare scenario in which the replication of configuration version files to standby nodes is unsuccessful or only partially successful. The root cause of this problem is currently unknown, but it is believed to be linked to restarts of processes on which the file replication depends.

•CSCek58687

Basic Description:

sconbkup process gets triggered periodically and does running-config backup after config commit.

Symptom:

The sconbkup process can consume a lot of CPU for an extended period of time (5 to 10 min).

Conditions:

This is observed following a config commit with a large config of about 4MB.

Workaround:

There is no workaround for this issue.

•CSCse83983

Basic Description:

IA 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 cant be set if PW is established with cbit=0

Symptom:

Router not sending Control Word even when Controlk word is enabled.

Conditions:

If a PW is established with cbit=0, and later via config we enabled control word or if neighbor sends a label mapping with control word cbit=1, IOX will still send cbit=0.

Workaround:

The workaround is to delete and reconfigure the PW on both the PE's

•CSCse80235

Basic Description:

L2VPN: Support destination with Rtg ID different than LDP rtr Id

Symptom:

Can't establish PW to a non LDP router ID address

Conditions:

PW can be established on to the LDP router ID. Currently IOX does not support PW to non LDP router ID's

Workaround:

None

Cisco CRS-1-specific Caveats

The following caveats are specific to the Cisco CRS-1 platform:

•CSCsg33747

Basic Description:

System instability after all fabric racks are OIRed

Symptom:

Multi-chassis system installability. Multiple processes will restart.

Conditions:

Following a power-down of all of the fabric-card chassis' within a multi-chassis system, the router will not operate in a stable manner.

---

Note Operating without at least one fabric chassis in service is not a supported configuration.

---

Workaround:

None

•CSCsg18108

Basic Description:

netio process restarts when trying to restore config 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.

Conditions:

Condition1: If the router has POS or serial interfaces and the configuration is cleared using following commands:

–commit replace

–yes

–end

And then restored back from disk, the netio process can terminate.

Condition 2: If the encapsulation of serial interface is changed repeatedly from ppp to hdlc and viceversa, and if the packets are being sent out of that interface at the same time, the netio process can 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.

•CSCek58420

Basic Description:

Bundle intf shut / no-shut causes autorp pkts to stop being sent to PIM

Symptom:

The auto-rp messages do not get delivered to the PIM process running on the RP. RP group mapping will not be known to PIM as a result.

Conditions:

The mhost default interface is configured to be one of the multicast enabled physical interfaces (and hence is a forwarding interface for the auro-rp routes). If an incoming interface is a bundle interface, when the bundle interface is 'bounced' (shut and unshut) the IC bit is not set on the egress forwarding interface, as expected by PIM.

Workaround:

Perform a shut/no shut on the mhost default interface

•CSCek56221

Basic Description:

HFR large combinational config - QOS config failed during router reload with EA error

Symptom:

The process hfr_pm may terminate unexpectedly during linecard bootup.

Conditions:

On linecard boot up, hfr_pm process may terminate. This will occur as a result of a failure in the L2VPN stats process initialization.

Workaround:

Reload the LC on which the problem occurred.

•CSCse67625

Basic Description:

When TCP packets of size that exactly equals the interface Maximum Transmission Unit (MTU) are transmitted, TCP does not receive back the acknowledgement leading to TCP retransmissions which further delays packets in the TCP send queue.

Symptom:

When this problem happens, the TCP send queue looks stuck for the duration TCP is attempting the retransmission. Depending on how long this condition persists and keepalive configuration on the router, some control sessions may flap.

Conditions:

When the router uses the default TCP Maximum Segment Size (MSS), which is derived from interface MTU, and the packet size exactly equals the MTU, the problem is seen.

Workaround:

Using tcp mssvalue command, set the TCP MSS to be smaller than interface MTU value.

Further Problem Description:

This only happens with specific PE scenarios as mentioned in Conditions and should not be a usual occurance.

Cisco XR 12000 Series Router-specific Caveats

The following caveats are specific to the Cisco XR 12000 Series Router platform:

•CSCsf08316

Basic Description:

ATM PVCs can flap when OAM is configured and certain changes are made.

Symptom:

After large-scale changes are made to the configuration, ATM PVCs may flap. This flap may occur up to 2 hours after the changes were initiated.

Conditions:

1000 PVCs configured, each with:

–ipv4 address

–ipv6 address

–OAM (one end of PVC)

–service-policy (other end of PVC)

The symptoms may occur after removing the IPV6 addresses from all of the PVCs, or after removing the OSPF portion of the config.

Workaround:

None known.

•CSCsg09471

Basic Description:

MTU changes on POS SPA interface can potentially reset the linecard.

Symptom:

A POS SPA can experience a reset after the MTU value is changed while traffic is running.

Conditions:

More than 750 subinterfaces configured on POS SPA and traffic is currently flowing through the SPA when MTU is changed.

Workaround:

None

•CSCsg19005

Basic Description:

Config roll back does not restore the configs completely

Symptom:

Configuration rollback does not restore the full configuration if used after using the commit replace CLI. When configuration rollback to latest rollback point is used, the configuration restoration does not work properly.

Conditions:

This is observed with a large-scale configuration:

–up to 60 cdp-enabled interfaces

–up to 112 ospf adjacencies

–in excess of 10,000 static routes

–up to 4000 interfaces on a given line card

Workaround:

Copy the config from backup.

example: copy disk0: router-config running config

Further Problem Description:

Using this command can actually make all the config lost.

•CSCsg07623

Basic Description:

IPv6 Multicast drops when OSPF Adjacency flaps

Symptom:

IPv6 Multicast traffic can potentially be dropped

Conditions:

–Engine-5 linecard

–Up to 8,000 MLD joins sent.

–OSPF adjacencies flap

Workaround:

None.

•CSCsg30178

Basic Description:

Buffer leak during long duration load test

Symptom:

During a load condition the SBC will suddenly halt call process and then return a SIP 487 message Request Terminated.

Conditions:

No calls are processed

Workaround:

None

•CSCsg40065

Basic Description:

Standby card goes into endless loop after switchover

Symptom:

After an SBC switchover the standby card is stuck in PreStandby

Conditions:

Under small load conditions and HA enabled

Workaround:

No workaround
