IOS (tm) 12000 Software (C12000-P-M), Version 12.0(21)SZ, RELEASE SOFTWARE

Upgrading to a New Software Release

For general information about upgrading to a new software release, see the Software Installation and Upgrade Procedure located at the following URL:

http://www.cisco.com/warp/public/130/sw_upgrade_proc_ram.shtml

Feature Set Table

The Cisco IOS software is packaged in feature sets consisting of software images—depending on the platform. Each feature set contains a specific set of Cisco IOS features.

Caution Cisco IOS images with strong encryption (including, but not limited to, 128-bit Triple Data Encryption Standard [3DES] data encryption feature sets) are subject to United States government export controls and have limited distribution. Strong encryption images to be installed outside the United States are likely to require an export license. Customer orders may be denied or subject to delay because of United States government regulations. When applicable, purchaser and user must obtain local import and use authorizations for all encryption strengths. Please contact your sales representative or distributor for more information, or send an e-mail to export@cisco.com.

Table 2 lists the features and feature sets supported by the Cisco 12000 Series Internet Routers in Cisco IOS Release 12.0 SZ and uses the following conventions:

•Yes—The feature is supported in the software image.

•No—The feature is not supported in the software image.

•In—The number in the "In" column indicates the Cisco IOS 12.0 S release in which the feature was introduced. For example, (7) means a feature was introduced in Cisco IOS Release 12.0(7)S. If a cell in this column is empty, the feature was included in the initial base release.

Note This table might not be cumulative or list all the features in each image. The parent release for Cisco IOS Release 12.0 S is Cisco IOS Release 12.0. To find information about inherited features, refer to Cisco.com or Feature Navigator. For Cisco.com, go to http://www.cisco.com/univercd/home/home.htm, select the appropriate software release under Cisco IOS Software, and click Release Notes.

1 In Cisco IOS Release 12.0(22)S, the Cisco Stateful Switchover with Nonstop Forwarding (SSO/NSF) feature is supported on the Route Processor (RP) but not on the Performance Route Processor (PRP). The SSO/NSF feature is supported on the PRP in Cisco IOS Release 12.0(23)S and later releases. However, in Cisco IOS Release 12.0(22)S, the PRP is NSF aware, meaning that it runs NSF software and can maintain session information with a peer device following a switchover of the peer device

2 SDCC is supported on Cisco 12000 Series Internet Router OC-48-based line cards.


New and Changed Information

This section lists the new hardware and software features supported by the Cisco 12000 Series Internet Routers in Cisco IOS Release 12.0 SZ:

New Features in Cisco IOS Release 12.0(23)SZ

The following new features are supported in Cisco IOS Release 12.0(23)SZ.

Precedence Rewrite Interoperability

Platform: Cisco 12000 Series Internet Routers

Prior to this release, remarked precedence did not change the output queuing, if the Egress line card was not an Engine 3 line card. In this event, the precedence remarking occurred after the output queue on the legacy line card had been selected.

With the precedence rewrite interoperability feature, the selection of local output queue or output queue is now performed after all MQC processing on the ingress is completed. Remarking of precedence now results in redirection to the appropriate egress queue for all line cards interoperating with Engine 3 line cards. Functionality is consistent for the following commands:

•set ip precedence

•set ip dscp

•set mpls experimental

Support for Eight Queues Per Slot or Physical Port in Engine 3 Line Cards

Platform: Cisco 12000 Series Internet Routers

The implementation of the ToFab queuing on Engine 3 line cards has been enhanced such that each slot or physical port now supports eight priority queues, with up to seven queues allocated for normal priority and one queue allocated for low latency/high priority. WRED and MDRR are configurable for each of the priority queues.

Load Balancing Enhancements with CEF for Engine 4+ Line Cards

Platform: Cisco 12000 Series Internet Routers

Engine 4+ line cards support a maximum number of eight buckets for IP or MPLS load balancing. CEF allows for up to sixteen buckets for IP or MPLS load balancing. Therefore, a discrepancy exists between the CEF bucket allowance and the maximum configurable on Engine 4+ line cards. This feature adds the following enhancements to load balancing for Engine 4+ line cards:

•The CEF algorithm now accounts for the bucket discrepancy and balances the traffic with equal distribution across all eight buckets.

•The output of the CEF command show ip cef prefex internal has been changed to include the hardware bucket size as well as the bucket count as follows: 

Load distribution: 0 1 2 3 4 0 1 2 3 4 0 1 2 3 4 (refcount 1)

Tags distribution: 0 1 2 3 4 0 1 2 3 4 0 1 2 3 4 (addr 44A21A18)

HW distribution: 0 1 2 3 4 (total 5 HW buckets)

Unequal Cost Enhancements to Load-Sharing Ratio

Platform: Cisco 12000 Series Internet Routers

This feature improves the IP routing algorithm such that the ratio of bucket distribution to path load sharing is a more precise integer value. Prior to this enhancement, some bucket allocations had led to distortions of the actual ratio when unequal cost load balancing was employed.

New Features in Cisco IOS Release 12.0(21)SZ

The following new features are supported in Cisco IOS Release 12.0(21)SZ.

Modular Fast Ethernet Line Card

Platform: Cisco 12000 Series Internet Routers

The Modular Fast Ethernet line card, the first modular line card for Gigabit Ethernet and Fast Ethernet on the Cisco 12000 Series Internet Routers, is designed for high-density and server-aggregation applications. It provides the Cisco 12416, Cisco 12410, Cisco 12406, and Cisco 12404 Internet Routers with up to 10 optical 802.3 Gigabit Ethernet interfaces. These interfaces provide high-speed interconnects to other network devices, such as other Cisco 12000 Series Internet Routers, or to other routers or layer 2 or layer 3 switches that support Gigabit Ethernet interfaces.

Because the Modular Fast Ethernet line card requires a card cage slot that is 1.8 inches (4.5 centimeters) wide, you can use the Modular Fast Ethernet line card in only the Cisco 12416 Internet Router, Cisco 12410 Internet Router, Cisco 12406 Internet Router, or Cisco 12404 Internet Router. The system must be configured for full switching fabric capacity, which is one clock and scheduler card (CSC) and three switch fabric cards (SFCs). The Modular Fast Ethernet line card requires one CSC plus three SFCs for the Cisco 12416 Internet Router, Cisco 12406 Internet Router, and Cisco 12404 Internet Router, but one CSC plus four SFCs (at least) for the Cisco 12410 Internet Router where the SFCs are all 10-Gigabit-capable.

Field-Replaceable SFP Gigabit Ethernet Laser Optical Transceiver Module

The Gigabit Ethernet laser optical transceiver module is a field-replaceable SFP module that plugs into the receptacle on the Ethernet port adapter (EPA) located on the Modular Fast Ethernet line card and provides the Gigabit Ethernet optical interface. The modules consists of two optical interfaces—laser transmit (TX) and laser receive (RX)—and an electrical interface (to the line card).

Note For more information on the Modular Fast Ethernet Line Card, refer to the Cisco.com documentation.

1-Port 10-Gigabit Ethernet Line Card

Platform: Cisco 12000 Series Internet Routers

The 1-Port 10-Gigabit Ethernet line card, the first 10-Gigabit Ethernet Router line card in the industry, is designed for high-density and server-aggregation applications. It provides the Cisco 12416, Cisco 12410, Cisco 12406, and Cisco 12404 Internet Routers with one optical 802.3ae 10-Gigabit Ethernet interface. This interface provides high-speed interconnects to other network devices, such as other Cisco 12000 Series Internet Routers, or to other routers or layer 2 or layer 3 switches that support 10-Gigabit Ethernet interfaces.

Because the 1-Port 10-Gigabit Ethernet line card requires a card cage slot that is 1.8 inches (4.5 cm) wide, you can use the 1-Port 10-Gigabit Ethernet line card in only the Cisco 12416 Internet Router, Cisco 12410 Internet Router, Cisco 12406 Internet Router, or Cisco 12404 Internet Router. The system must be configured for full switching fabric capacity, which is one clock and scheduler card (CSC) and three switch fabric cards (SFCs). In addition, the 1-Port 10-Gigabit Ethernet line card requires a switch fabric that supports 10-Gigabit Ethernet, available only on the Cisco 12416 Internet Router, Cisco 12410 Internet Router, Cisco 12406 Internet Router, and Cisco 12404 Internet Router.

10-Gigabit Ethernet Laser Optical Transceiver

The 10-Gigabit Ethernet laser optical transceiver is hardwired to the 1-Port 10-Gigabit Ethernet line card and provides the 10-Gigabit Ethernet optical interface. The port consists of two optical interfaces—laser transmit (TX) and laser receive (RX)—and an electrical interface (to the line card). The 10-Gigabit Ethernet transceiver is a long haul, or long wavelength, (1310 nm nominal) transceiver, used for 1000BASE-LR links.

Note For more information on the 1-Port 10-Gigabit Ethernet line card, refer to the Cisco.com documentation.

8-Port OC-3 STM-1 ATM Line Card

Platform: Cisco 12000 Series Internet Routers

The 8-Port OC-3 Synchronous Transfer Mode -1 (STM-1) Asynchronous Transfer Mode (ATM) line card is supported by all Cisco 12000 Series Internet Routers in Cisco IOS Release 12.0(21)SZ.

The 8-Port OC-3 STM-1 ATM Line Card supports traffic shaping, and delivers line rate OC-3/STM-1 bandwidth while performing traffic shaping and per-virtual circuit (VC) queueing. It also supports per-VC MDRR (Modified Deficit Round Robin) and per-VC low latency queueing (LLQ).

CBWFQ is implemented on a per-VC basis, with up to eight queues per VC. One of the queues is a low-latency queue. Both per-VC WRED and per-VC CBWFQ are performed in hardware.

The 8-Port OC-3 STM-1 ATM line card provides the Cisco 12000 Series Internet Router with eight 155 Mbps ATM interfaces. The card communicates with the Cisco 12000 Series Internet Router switch fabric.

Note For more information on the 8-Port OC-3 STM-1 ATM Line Card, refer to the Cisco.com documentation.

Important Notes for Cisco IOS Release 12.0 SZ

Please be aware that failure to upgrade the affected IOS images may result in network downtime.

Caveats

Caveats describe unexpected behavior in Cisco IOS software releases. Severity 1 caveats are the most serious caveats; severity 2 caveats are less serious. Severity 3 caveats are moderate caveats, and only select severity 3 caveats are included in the caveats document.

Because Cisco IOS Release 12.0 SZ is based on Cisco IOS Release 12.0, many caveats that apply to Cisco IOS Release 12.0 will also apply to Cisco IOS Release 12.0 S. For information on severity 1 and 2 caveats in Cisco IOS Release 12.0, see the Caveats for Cisco IOS Release 12.0 document located on Cisco.com and the Documentation CD-ROM.

Note If you have an account with Cisco.com, you can also use the Bug Toolkit to find select caveats of any severity. To reach the Bug Toolkit, log in to Cisco.com and click Service and Support: Technical Assistance Center: Select & Download Software: Jump to a software resource: Software Bug Toolkit/Bug Watcher. Another option is to go to
http://www.cisco.com/cgi-bin/Support/Bugtool/launch_bugtool.pl.

The caveats section consists of the following subsections:

•Open Caveats—Cisco IOS Release 12.0(23)SZ

•Resolved Caveats—Cisco IOS Release 12.0(23)SZ

•Resolved Caveats—Cisco IOS Release 12.0(21) SZ

Open Caveats—Cisco IOS Release 12.0(23)SZ

This section describes possibly unexpected behavior by Cisco IOS Release 12.0(23) SZ.

For more information on open caveats in Cisco IOS Release 12.0(23)S, refer to the Caveats for Cisco IOS Release 12.0 document.

•CSCdz28243

Precedence Rewrite Interperability between Engine 3 and Legacy Engine Local Output Queue/Output Queue

Forwarding performance on Engine 3 line cards drops to 3.63 Mpps with 40 byte packet size load balancing between four paths. Without load balancing, performance can reach 3.97 Mpps.

Resolved Caveats—Cisco IOS Release 12.0(23)SZ

The following caveats were resolved in Cisco IOS Release 12.0(23)SZ. For resolved caveats specific to Cisco IOS Release 12.0(23)S, see the Caveats for Cisco IOS Release 12.0 document. The caveats document is updated for every maintenance release and is located on Cisco.com and the Documentation CD-ROM.

•CSCdx87564

Tos bit change does not change the output queue.

Prior to this release, there was no ability to set the IP Precedence, IP DSCP, or MPLS EXP bits for the ingress of Engine 3 line cards, hence no egress port match and allocation to the correct output queue. This release fixes this limitation by making the ingress able to mark the traffic using any supported traffic marking-mechanism, such as MQC policies, PBR, or QPPB.

•CSCdw42820

Legacy CLI should allow at leaset 2 DRR queues on top of SPQ on ToFab queue.

Before this release, Engine 3 line cards were able to support two ToFab or ingress queues per Cisco 12000 Series Internet Router destination slot. With this release, the implementation of ToFab queuing has been changed so that each slot or physical port has seven low priority queues. RED can be performed on all these queues. This implementation is similar to the Engine 2 line card implementation of ToFab queuing, except for the priority queue. There is one priority queue per destination slot on Engine 3 line cards, as this is a hardware restriction.

•CSCdz43313

2 QoS Phase: set ip/exp does not work on Engine 3 line card egress.

Setting IP Precedence, IP DSCP, or MPLS EXP bits function was broken prior to this release. Now the user is able to use MQC outbound policy applied on Engine 3 line card interfaces to change the mentioned values on the header of the IP or MPLS packet header.

Resolved Caveats—Cisco IOS Release 12.0(21) SZ

There are no resolved caveats for Cisco IOS Release 12.0(21)SZ.

For resolved caveats specific to Cisco IOS Release 12.0(21)S, see the Caveats for Cisco IOS Release 12.0 document. The caveats document is updated for every maintenance release and is located on Cisco.com and the Documentation CD-ROM.

•Priority level 3 (P3)—Your network performance is degraded. Network functionality is noticeably impaired, but most business operations continue.

•Priority level 2 (P2)—Your production network is severely degraded, affecting significant aspects of business operations. No workaround is available.

•Priority level 1 (P1)—Your production network is down, and a critical impact to business operations will occur if service is not restored quickly. No workaround is available.

Which Cisco TAC resource you choose is based on the priority of the problem and the conditions of service contracts, when applicable.

Cisco TAC Web Site

The Cisco TAC Web Site allows you to resolve P3 and P4 issues yourself, saving both cost and time. The site provides around-the-clock access to online tools, knowledge bases, and software. To access the Cisco TAC Web Site, go to the following URL:

http://www.cisco.com/tac

All customers, partners, and resellers who have a valid Cisco services contract have complete access to the technical support resources on the Cisco TAC Web Site. The Cisco TAC Web Site requires a Cisco.com login ID and password. If you have a valid service contract but do not have a login ID or password, go to the following URL to register:

http://www.cisco.com/register/

If you cannot resolve your technical issues by using the Cisco TAC Web Site, and you are a Cisco.com registered, you can open a case online by using the TAC Case Open tool at the following URL:

http://www.cisco.com/tac/caseopen

If you have Internet access, it is recommended that you open P3 and P4 cases through the Cisco TAC Web Site.

Cisco TAC Escalation Center

The Cisco TAC Escalation Center addresses issues that are classified as priority level 1 or priority level 2; these classifications are assigned when severe network degradation significantly impacts business operations. When you contact the TAC Escalation Center with a P1 or P2 problem, a Cisco TAC engineer will automatically open a case.

Before calling, please check with your network operations center to determine the level of Cisco support services to which your company is entitled; for example, SMARTnet, SMARTnet Onsite, or Network Supported Accounts (NSA). In addition, please have available your service agreement number and your product serial number.
