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), Routing Information Protocol (RIP), Intermediate System-to-Intermediate System (IS-IS), Open Shortest Path First (OSPF), IP Multicast, Routing Policy Language (RPL), Hot Standby Router Protocol (HSRP), or Virtual Router Redundancy Protocol features (VRRP).

•BGP Prefix Independent Convergence—Provides the ability to converge BGP routes within sub seconds instead of multiple seconds. The Forwarding Information Base (FIB) is updated, independent of a prefix, to converge multiple 100K BGP routes with the occurrence of a single failure. This convergence is applicable to both core and edge failures and with or with out MPLS. This fast convergence innovation is unique to Cisco IOS XR software.

•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 Virtual Private Network (L3VPN).

•Multicast—Provides comprehensive IP Multicast software including Source Specific Multicast (SSM). Cisco Carrier Routing System (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 version3 (SNMPv3). Control plane protections integrated into line card Application-Specific Integrated Circuits (ASICs) include Generalized TTL Security Mechanism (GTSM), RFC 3682, and Dynamic Control Plane Protection (DCPP).

•Craft Works Interface (CWI)—CWI is a client-side application used to configure and manage Cisco routers. 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).

•Multicast service delivery in SP NGN—MVPNv4 support carries multicast traffic over an ISP MPLS core network.

•Cisco IOS IPv6 Provider Edge Router support for IPv6 applications—Delivers IPv6 traffic over an IPv4/MPLS core with Cisco IOS IPv6 Provider Edge Router (6PE) support (Cisco XR 12000 Series Router only).

•IPv6 VPN over MPLS (6VPE) support—Delivers IPv6 VPN over MPLS (IPv6) VPN traffic over an IPv4 or MPLS core with 6VPE support (Cisco XR 12000 Series Router only).

•6VPE over L2TPv3 support—Delivers IPv6 VPN traffic over L2TPv3 core with 6VPE support (Cisco XR 12000 Series Router only). This feature is also available on Cisco IOS Software.

•Enhanced core competencies:

–Support for IS-IS and OSPF.

–IP fast convergence with Fast Reroute (FRR) support for Intermediate System-to-Intermediate System (IS-IS)

–Traffic engineering support for unequal load balancing

–Path Computation Element (PCE) capability for traffic engineering

•Firewall Services—Seamless insertion of Firewall Services in the data path with Virtual Firewall support on Multiservice Blade (XR-12K-MSB) for the Cisco XR 12000 Series Router.

•VPN IPSec Aggregation—The IPSec Aggregation feature is provided through SPA-IPSEC-2G-2 card. The IPSec Aggregation feature allows you to terminate up to 64-K VPN tunnels, both site-to-site and remote access, if four VPN SPAs are used.

•Voice Video—Voice Video interconnect between providers with Session Border Controller (SBC) on the Cisco XR 12000 Series Router.

•L2TPv3 Tunneling Mechanism—Service Providers who do not use MPLS in the core, but want to offer VPN services can use the L2TPv3 tunneling mechanism. This feature support includes IPv4 (VPNv4) and IPv6 (6VPE) VPN services using L2TPv3 encapsulation. The L2TPv3 packet is encapsulated in an IPv4 delivery header and is carried across an IPv4 backbone. VPN prefixes are advertised with BGP labels and resolved over L2TPv3 tunnels.

For more information about new features provided on various platforms for Cisco IOS XR Software Release 3.6.2, see the "New Features and Enhancements" section in this document.

•Restrictions for LDP-IGP Synchronization Enhancements for OSPF

•LDP-IGP Synchronization Enhancements for OSPF: New or Changed Commands

LDP-IGP Synchronization Enhancements for OSPF

With this feature, Interior Gateway Protocol (IGP) advertises maximum metric over a link on which LDP synchronization is enabled until the LDP session on the corresponding link is up and has converged. This is referred to as synchronization. This ensures that the link chosen is the one least used unless it is the only available path for forwarding both IP and MPLS traffic until LDP has exchanged labels over the link. This avoids "black-holing" of multilabel traffic such as virtual private networks (VPN) traffic, which can occur when outbound label information is unavailable.

Information About LDP-IGP Synchronization Enhancements for OSPF

This feature is supported on both the Cisco CRS-1 router and the Cisco XR 12000 Series Router.

LDP-IGP synchronization is enabled under OSPF and IS-IS. However, the CLI changes being introduced in the current release affect OSPF protocol only.

Restrictions for LDP-IGP Synchronization Enhancements for OSPF

Under IS-IS, this feature supports an IPv4 unicast topology, while under OSPF, it supports an IPv4 unicast VRF-default topology.

LDP-IGP Synchronization Enhancements for OSPF: New or Changed Commands

This feature affects the following commands:

•mpls ldp sync-igp-shortcuts

•show mpls ldp igp sync

•debug mpls ldp igp sync

•mpls ldp igp sync delay (LDP)

•show ospf interface

mpls ldp sync-igp-shortcuts

To enable LDP-IGP synchronization shortcuts in an MPLS network, use the mpls ldp sync-igp-shortcuts command in the appropriate OSPF configuration mode. To return to the default behavior, use the no form of this command.

mpls ldp sync-igp-shortcuts [disable]
no mpls ldp sync-igp-shortcuts
Syntax Description

disable

(Optional) Disables MPLS LDP synchronization with IGP shortcuts from within the OSPF interface and area configuration submodes only. For the OSPF router configuration mode, use the no form of this command.

Defaults

No default behavior or values

Examples

The following example shows how to enable LDP-IGP synchronization shortcuts under OSPF interface configuration, using the mpls ldp sync-igp-shortcuts command on a tunnel-te interface. However, the command applies to all interfaces under the applicable configuration mode.
RP/0/RP0/CPU0:router(config)# router ospf 100
RP/0/RP0/CPU0:router(config-ospf)# area 0 
RP/0/RP0/CPU0:router(config-ospf-ar)# interface tunnel-te 1
RP/0/RP0/CPU0:router(config-ospf-ar-if)# mpls ldp sync-igp-shortcuts 
show mpls ldp igp sync

The tunnel-te interface was added as a new interface type available to the existing show mpls ldp igp sync command.

show mpls ldp igp sync [interface {tunnel-te {tunnel-range}}]

debug mpls ldp igp sync

The tunnel-te interface was added as a new interface type available to the existing debug mpls ldp igp sync command.

debug mpls ldp igp sync [interface type instance] [location node-id]

mpls ldp igp sync delay (LDP)

To configure an LDP-IGP synchronization delay within an MPLS network, use the mpls ldp igp sync delay command in global configuration mode. To return to the default behavior, use the no form of this command.

mpls ldp igp sync delay delay-time
no mpls ldp igp sync delay delay-time
Syntax Description

delay-time

Time, in seconds, for the delay in synchronization. The range is from 5-60.

show ospf interface

The show ospf interface command output now includes the new interface type tunnel-te.

show ospf instance-name interface [type interface-path-id]
The following example shows the new output information for the show ospf interface command:
RP/0/0/CPU0:router# show ospf 1 interface tunnel-te 1

MPLS Traffic Engineering and Fast-Reroute Enhancements on OSPF

MPLS Traffic Engineering (MPLS-TE) and Fast Reroute (FRR) features supported in Cisco IOS XR Software Release 3.6.2 allow the IGP-area in which constraint-based shortest path first (CSPF) is performed to be specified in tunnel configuration.

In conjunction with the support of 25 IGP areas, there are no longer hard limits on the number of adjacencies permitted on a single link.

Restrictions for MPLS Traffic Engineering and Fast-Reroute Enhancements on OSPF

Only point-to-point interfaces are supported for OSPF multiple adjacencies. These may be either native point-to-point (P2P) interfaces or broadcast interfaces on which the OSPF P2P configuration command is applied to force them to behave as P2P interfaces as far as OSPF is concerned. This restriction does not apply to IS-IS.

Note The tunnel-te interface is not supported under IS-IS.

MPLS Engineering Shared-Risk Link Group (SRLG)

The term shared-risk link groups (SRLG) refers to situations in which links in a network share a common fiber (or a common physical attribute). If one link fails, other links in the group may fail too. Links in the group have a shared risk.

The MPLS traffic engineering SRLG feature enhances backup tunnel path selection, so that a backup tunnel does not use links that are in the same SRLG as the interfaces the backup tunnel is protecting. Otherwise, when the protected link fails, the backup tunnel fails too.

There are two ways to avoid a backup tunnel using the same links in the SRLG as its protected interface:

•The router does not create the backup tunnel unless it avoids SRLGs of the protected interface.

•The router tries to avoid SRLGs of the protected interface but, if that fails, the router creates the backup tunnel anyway. In this case, there are two explicit paths. The first explicit path tries to avoid the SRLGs of the protected interface. If that does not work, the backup tunnel uses the second path, which ignores SRLGs.

Intermediate System-to-Intermediate System (IS-IS) floods the SRLG membership information (including other TE link attributes such as bandwidth availability and affinity), so that all routers in the network have the SRLG information for each link. With this topology information, routers can compute backup tunnel paths that exclude links having SRLGs in common with their protected interfaces.

How to Configure MPLS Traffic Engineering Shared-Risk Link Groups

Note The current implementation of this MPLS feature requires a dual operating system approach in your network.

To activate the MPLS traffic engineering SRLG feature, perform the following tasks:

•Configure the SRLG membership of each link that has a shared risk with another link. See "Configuring the SRLG Membership of Each Link That Has a Shared Risk with Another Link" in the current document.

•Configure the router acting as a point of local repair (PLR) in the network to automatically create backup tunnels that avoid the SRLGs of the protected interfaces. See the Cisco IOS Software documentation "Configuring the Routers That Automatically Create Backup Tunnels to Avoid SRLGs of Their Protected Interfaces" under MPLS Traffic Engineering: Shared Risk Link Groups (SRLG) for Cisco IOS Software Release 12.0S at http://www.cisco.com/en/US/docs/ios/12_0s/feature/guide/fs29srlg.html .

Prerequisites for MPLS Traffic Engineering Shared-Risk Link Groups

•To be able to set up auto-tunnels, you must have one router in the network in which you intend to use this feature configured as a point of local repair (PLR), and the router must be running
Cisco IOS, Release 12.0 S.

Restrictions for MPLS Traffic Engineering Shared-Risk Link Groups

•Cisco IOS XR MPLS-TE does not currently support auto-tunnels.

Using MPLS Tunnel Drop Counts to Display Drop or Error Packets on MPLS TE Interfaces

Two new fields displaying drop and error packets were added to the output of the show interfaces tunnel-te command, which runs only on the Cisco CRS-1 router.

show interfaces tunnel-te

To verify whether or not there are drop or error packets on MPLS traffic engineering (TE) tunnel interfaces, use the show interfaces tunnel-te command in EXEC mode.

Usage Guidelines

To use this command, you must be in a user group associated with a task group that includes the proper task IDs. For detailed information about user groups and task IDs, see the Configuring AAA Services on Cisco IOS XR Software module of Cisco IOS XR System Security Configuration Guide.

The show interfaces tunnel-te command, which runs only on the Cisco CRS-1 router, was modified by the addition of two new fields, drop counter and error counter.

Note FRR drops cannot account for the total packet loss seen end-to-end during FRR. Rather, the command output accounts only for packets dropped by the forwarding path, because the software is programmed to recognize that the primary interface is down and that the backup is not on the same line card.

Field Descriptions

Field¹

Description

drop counter

Displays dropped packets that result from oversubscription of the egress link hosting the TE-tunnel in an MPLS network

error counter

Displays packets dropped during a fast-reroute (FRR) on the line card hosting the primary TE tunnel in an MPLS network.

New and Enhanced Fabric Diagnostic Tests

The following new functionality is being introduced with the current release:

•Fabric Diagnostic Test—Enhancement of the existing test.

•Fabric Multicast Diagnosis Test—A new fabric diagnostic test for multicast networks.

Fabric Diagnostic Test

A nondisruptive, fault isolation test that "unicast pings" each RP/LC/DRP node in a chassis from the standby RP node using a unicast address. The test steers unicast ping test packets through different fabric planes, aggregates unicast ping (pass or fail) results with fabric plane information, analyzes these results, and points out the most logical point of failure (if any) in the chassis. The test can be executed only from the standby RP as one of the following test types:

•On demand

•Scheduled

•Configured to monitor health

Executing this test in a Cisco CRS-1 multishelf system may help determine which fabric stage (S1, S2, or S3) is the most logical point of failure for unicast in the system.

This test must be run in each LC rack standby RP in the system. For example, if the test reports failures on multiple LC racks, and the failure information points to the same fabric plane, then the most likely point of failure is the S2 stage, which is the card in the fabric chassis of the system.

Fabric Multicast Diagnosis Test

Added for multicast networks in Release 3.6.2, this nondisruptive, fault isolation test that "multicast pings" each RP/LC/DRP node in a chassis from the standby RP node using a multicast address. The test steers multicast ping test packets through different fabric planes, aggregates multicast ping (pass or fail) results with fabric plane information, analyzes these results, and points out the most logical point of failure (if any) in the chassis. The test can be executed only from the standby RP as one of the following test types:

•On demand

•Scheduled

•Configured to monitor health

Executing this test in a Cisco CRS-1 multishelf system may help determine which fabric stage (S1, S2, or S3) is the most logical point of failure for multicast in the system.

This test must be run in each LC rack standby RP in the system. For example, if the test reports failures on multiple LC racks, and the failure information points to the same fabric plane, then the most likely point of failure is the S2 stage, which is the card in the fabric chassis of the system.

Important Notes

•Country-specific laws, regulations, and licences—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.

•Migrating from Cisco IOS to Cisco IOS XR Software on the Cisco XR 12000 Series Router—When migrating a Cisco XR 12000 Series Router from Cisco IOS to Cisco IOS XR software, follow the instructions provided in Migrating from Cisco IOS to Cisco IOS XR Software on the Cisco XR 12000 Series Router, Release 3.6.

•Card, fan controller, and RP removal—For all card removal and replacement (including fabric cards, line cards, fan controller, and RP) follow the instructions provided by Cisco to avoid impact to traffic. See the Cisco IOS XR Getting Started Guide for procedures.

•Exceeding Cisco testing—If you intend to test beyond the combined maximum configuration tested and published by Cisco, contact your Cisco Technical Support representative to discuss how to engineer a large-scale configuration maximum for your purpose.

•More power required for Cisco SIP-600 line cards on the Cisco XR 12000 Series Router—These line cards draw more power than the previous ones. 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

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.

•Per-interface Internet Control Message Protocol (ICMP) disable feature is not supported on Cisco XR 12000 Series Routers.

•Disable the preempt feature in the VFW application—In all Cisco IOS XR 3.6 releases, you must disable the preempt feature in the VFW application. Ensure that you use the no preempt command for all fault-tolerant groups under the Admin context on the VFW application. See the following example:
ft group 1
  peer 1
  no preempt
  associate-context ctx1
  inservice
•Online Diagnostics is not supported on the Cisco XR 12000 Series Router—If you execute the diagnostic command, an error appears stating that there is no online diagnostics process running on the router.

•rp mgmtethernet forwarding command—This command is not supported on the Cisco XR 12000 Series Router.

Minimum Flash Disk Requirements When Upgrading to Release 3.6.2

•Cisco CRS-1—As of Cisco IOS XR Release 3.6.2, the Cisco CRS-1 router supports an upgrade from the 1-GB flash disk to either a 2-GB or 4-GB flash disk. It is not, however, a requirement unless you are upgrading from Cisco IOS XR Software Release 3.5.4.

Note If you are upgrading from Release 3.5.4 to Release 3.6.2, you must, at minimum, upgrade to 2 GB of flash memory.

It is recommend that, before you upgrade from Cisco IOS XR Software Release 3.5.4 to Cisco IOS XR Software Release 3.6.2, you install all recommended Release 3.5.4 SMUs.

Be aware that an installation of Cisco IOS XR Software Release 3.6.2, with all optional packages installed, requires at least 450 MB of free flash disk memory. For this reason, make sure that you have enough free space available before you try to upgrade to Release 3.6.2.

Tip Cisco CRS-1 platform customers should consider upgrading to 4-GB flash disk memory before installing Cisco IOS XR Software Release 3.6.2. An upgrade of the flash disk memory to 2 GB or more is required in Cisco IOS XR Software Release 3.7.0. However, because more than 2 GB of flash memory may be required in later releases, upgrading now to 4 GB of flash memory saves you this effort in future.

•Cisco XR 12000 Series Router—Starting with Cisco IOS XR Software Release 3.6.0, an upgrade from the 1-GB to 2-GB flash memory is required on the Cisco XR 12000 Series Router.

Table 7 specifies the Cisco IOS XR releases when the flash memory upgrade is mandatory for the Cisco CRS-1 router and the Cisco XR 12000 Series Router.

¹Supports 2- and 4-GB flash disk memory on both platforms.

²Upgrade to 2 GB or 4 GB of flash disk memory is only compulsory if you are upgrading from Release 3.4.0.

³Upgrade to 2 GB or 4 GB of flash disk memory is only compulsory if you are upgrading from Release 3.5.4. An upgrade from any other previous release does not require this.

The flash disk size of a Cisco CRS-1 router or Cisco XR 12000 Series Router running Cisco IOS XR Software Release 3.4.0, Release 3.5.0, or Release 3.6.1 can be either 1 GB, 2 GB, or 4 GB.

Note The flash disk size upgrade from 2 GB to 4 GB is also supported for Cisco IOS XR Software Release 3.4.0 and Release 3.5.0 for both router platforms, with the following restriction: Cisco IOS XR Software Release 3.4.0 and Release 3.5.0 are not capable of showing the 4-GB flash disk and it appears as though only a 2-GB Flash Disk were present. As of Cisco IOS XR Software Release 3.6.0, the 4-GB flash disks appear as two 2-GB partitions.

For details about these flash disks, including the upgrade procedure for both platforms, see the flash disk upgrade instructions at:

http://www.cisco.com/en/US/docs/routers/xr12000/xr_line_cards/flashdisk/flashdisk.pdf.

Activation Requirements for the Cisco CRS-1 Multishelf System Encryption PIE

Previously the Cisco CRS-1 multishelf system encryption PIE was installed and activated when you ordered the Cisco IOS XR IP/MPLS Core Software 3DES image.

With this release, you must explicitly activate the Cisco IOS XR IP/MPLS Core Software 3DES image [hfr-k9sec-p.pie-3.6.2, PID is XC-RPK9-03.06], by following these instructions:

http://www.cisco.com/en/US/docs/ios_xr_sw/iosxr_r3.6/system_management/configuration/guide/yc36inst.pdf

Caveats

Caveats describe unexpected behavior in Cisco IOS XR software releases. Severity-1 caveats are the most serious.

Open Caveats—Release 3.6.2

This section lists the caveats for Cisco IOS XR Software Release 3.6.2:

•Cisco CRS-1 and Cisco XR 12000 Series Router Caveats

•Caveats Specific to the Cisco CRS-1 Router

•Caveats Specific to the Cisco XR 12000 Series Router

Cisco CRS-1 and Cisco XR 12000 Series Router Caveats

The following caveats apply to both platforms:

•CSCeg39062

Basic Description:

Using FTP to install packages may result in incorrect parsing of the FTP URL. URLs that have multiple slashes may be sent to the server as a relative path instead of an absolute path.

Conditions:

Use of a path such as ftp://username:password@server//directory/file normally initiates an attempt to download /directory/file from the server. However, due to incorrect parsing, an attempt is actually made to download $HOME/directory/file instead.

Workaround:

Two possible workarounds exist:

–Locate the target file in the user's home directory, so that it can be accessed through a relative path. Use of syntax such as the following solves the problem illustrated under "Conditions," and the command operates correctly, because it looks for a relative file location:
ftp://username:password@server/directory/file downloads $HOME/directory/file
–Use alternative transport mechanism, such as TFTP.

•CSCso79938

Basic Description:

SNMP traps such as coldStart, warmStart are missing.

Detailed Problem Description:

At startup, the SNMP agent uses information in RIB to identify whether configured SNMP trap recipients are reachable. After the SNMP agent detects them as reachable, the SNMP agent forwards traps generated by various MIB DLLs.

Availability of the route does not guarantee reachability to destination. FIB should have updated its forwarding path by performing an ARP, so that traps generated from the SNMP agent reach their destination. This fails to occur, however, and traps generated by the SNMP agent do not reach their destinations.

Conditions:

System reload or switchover of the active controller card.

Workaround:

None.

Generating a few packets to destination would cause the necessary forwarding agent to trigger an ARP for those packets, and that would result in the complete setup of Layer 2 adjacencies. In this case, the SNMP agent would execute ICMP PING to the configured trap destination before commencing SNMP trap forwarding.

•CSCsl29159

Basic Description:

The netio process crashes while enabling debug commands with ACL filter.

Symptom:

Sometimes, the netio process terminates abnormally when debug cef command with acl filter is used.

Conditions:

The problem occurs when the user enables debug cef packet ipv4acl and there is slowpathipv6 traffic being switched.

Workaround:

Specify the afi filter to the debug cef command that matches the type of debug acl being supplied to the debug command.

For example, use the commands in the following formats:

–debug cef ipv4 packet [level<n>] ipv4acl

Or

–debug cef ipv6 packet [level <n>] ipv6acl

•CSCsq09232

Basic Description:

Connection to TACACS lost on RP failover.

Symptom:

After RP failover, a pre-existing exec (telnet) user is unable to execute any command. The issue is not seen consistently. However whenever it occurs, the EXEC user is not allowed to execute any command.

Conditions:

After RP failover when the EXEC session is replicated, it initiates an Interprocess Communications (IPC) connection to the locald process. This connection attempt fails at times, if locald is still not available. This could have happened if the system and thereby locald is still initializing. In such a case, if command authorization is configured, EXEC is unable to verify authorization for the command (as no channel is available to communicate request to locald). As such, the user is denied permission to execute the command.

Workaround:

Exit from the session and log in again.

Caveats Specific to the Cisco CRS-1 Router

•CSCsr49786

Basic Description:

LPTS application (lpts_pa) runs out of its allocated pool of Fabric Group Identifiers (FGIDs) and is not able to allocate any new FGIDs.

Symptom:

When this problem is observed, LPTS client applications, services, or protocols may stop functioning correctly. For example, protocols such as PIM, OSPF, or BGP that execute on the RP may not be able to establish neighborships or receive packets.

This may be seen following an RP failover event.

Conditions:

LPTS may hit its FGID limit after several RP failovers. The number of RP failovers required to hit this max limit depends on the number of FGIDs allocated by LPTS. To see the allocation, use the administration-level command show controller fabric fgid stat pool detail | beg LPTS.

In the sample output below, the InUse FGIDs is 512:
Pool Name is LPTS
Pool type is Dedicated
The starting FGID of this pool is 11264
Total FGIDs of this pool is 32768
InUse FGIDs of this pool is 512
High Water Mark InUse FGIDs of this pool is 512 
The following example shows the state observed if this issue is encountered:
Pool Identifier is 1
Pool Name is LPTS
Pool type is Dedicated
The starting FGID of this pool is 11264
Total FGIDs of this pool is 32768
InUse FGIDs of this pool is 32768
High Water Mark InUse FGIDs of this pool is 0 
Because the InUse FGID value equals the Total FGID value, no further FGIDs can be allocated.

Workaround:

Periodically restart the lpts_pa process on the active RP with the command process restart lpts_pa to ensure that FGIDs are available. The lpts_paprocess can be restarted without any impact to services. If the issue has been encountered, restarting lpts_pa can be used to recover from the situation.

•CSCsl09040

Basic Description:

If a class has bandwidth remaining percent 0 configured, that class may receive more bandwidth than the minimum bandwidth configured in that class.

Conditions:

This behavior is observed in classes where bandwidth remaining percent 0 has been configured.

Workaround:

Configure shape bandwidth to be the same as minimum bandwidth of that class.

•CSCsu63356

Basic Description:

Copying a very large prefix set, or a configuration with a very large prefix set, to the running configuration takes 30 minutes or more due to the prefix set verification process. The larger the prefix list, the more time it takes.

Conditions:

This condition is seen under the following circumstances:

–When applying a very large prefix list to running configuration.

–When rolling back the configuration after the prefix list has been deleted.

Workaround:

None.

•CSCsl67014

Basic Description:

Sometimes, exec process is terminated when describe CLI commands are used.

Symptom:

WD sysmon may terminate the exec process if there is a severe increase in CPU usage.

Conditions:

This symptom is observed on Cisco CRS-1 routers when using the command describe show tech-support or describe show screddrv standby.

Workaround:

None. However, this problem appears very rarely and there is no impact to the functionality of the router.

Caveats Specific to the Cisco XR 12000 Series Router

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

•CSCsh50132

Basic Description:

Ace error messages appear and the traffic stops during spa-mix while sending IPSec and Clear IP Traffic over SPA-4XCT3/DS0 and SPA-IPSEC-2G.

Symptom:

Fails to process HAPI rx packet when spa-mix.

Conditions:

–High rate traffic, over 600 Mpbs.

–With spa-mix, when two IPSec SPA on the same linecard or IPSecSPA and other SPA types.

Workaround:

If the IPSec SPA is used at full rate (1 Gbps per direction), locate the other SPA on a separate line card.

•CSCsk56789

Basic Description:

Bit error rate test (BERT) errors for the 3-in-24 pattern on the channel-group BERT for the 8-Port Channelized T1/E1 Shared Port Adapters (SPA).

Symptom:

Invoking BERT pattern 3-in-24 on the channel-group may result in BERT errors incrementing for the 8-Port Channelized T1/E1 SPA.

Conditions:

For the 8-Port Channelized T1/E1 SPA, invoking BERT pattern 3-in-24 on the channel-group may result in an increase in BERT errors.

Workaround:

None. There is no impact on the functionality of the system.

•CSCsl58364

Basic Description:

After a physical OIR, the show environment command reports incorrect values for the services card.

Symptom:

After a physical OIR of the Services card, the temperature for that slot disappears (as seen in the show environment temperatures command).

Conditions:

After an OIR, the show temperature command does not display the temperature for the services card.

Workaround:

None.

•CSCsl54803

Basic Description:

Before initiating field diagnostics, the user is not warned to remove the cabling from the linecard under test.

Symptom:

Unexpected interrupts while field diagnostics are in progress.

Conditions:

–External cables are connected to the line card

–Field diagnostics is initiated on the line card

Workaround:

Remove all external cables to the line card under test before initiating field diagnostics.

Upgrading Cisco IOS XR Software

Cisco IOS XR software is installed and activated from modular packages, allowing specific features or software patches to be installed, upgraded, or downgraded without affecting unrelated processes. Software packages can be upgraded or downgraded on all supported card types, or on a single card (node).

Software packages are installed from package installation envelope (PIE) files that contain one or more software components.

The following URL contains links to information about how to upgrade Cisco IOS XR software:

Note Refer to the "Minimum Flash Disk Requirements When Upgrading to Release 3.6.2" section for upgrade details.

Using a Software Maintenance Update (SMU)

A SMU is used as a software `patch' delivery unit that after installation and activation provides a `point-fix' for a critical issue in a given software release. The SMU consists of a SMU file and an associated caveat listing.

You should remember to periodically check the online SMU download page for new SMUs that may apply to your software release. Go to this URL and then click on IOS XR Software Maintenance Upgrades (SMU):

The following URL points to SMU FAQs to assist you with questions you may have regarding how and when to install SMUs for your release:
