Determining the Software Version
To determine the version of Cisco IOS software running on your Cisco 7000 family router, log in to the Cisco 7000 family router and enter the show version EXEC command:
Router> show versionCisco Internetwork Operating System SoftwareIOS (tm) 7200 Software (C7200-JS-MZ), Version 11.2(26)P, RELEASE SOFTWAREUpgrading to a New Software Release
For general information about upgrading to a new software release, see Cisco IOS Upgrade Ordering Instructions located at:
http://www.cisco.com/warp/public/cc/pd/iosw/prodlit/957_pp.htm
Microcode Software
Microcode software images are bundled with the system software image—with the exception of the Channel Interface Processor (CIP) microcode (all system software images). Bundling eliminates the need to store separate microcode images. When the router starts, the system software unpacks the microcode software bundle and loads the proper software on all the interface processor boards. Table 4 lists the current microcode version for the Cisco 7000 family.
Feature Set Tables
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.
Cisco IOS Release 11.2(26)P supports the same feature sets as Cisco IOS Release 11.2(25).

For more information on the PA-12E/2EF port adapter, refer to the publication PA-12E/2FE Ethernet Switch 10BaseT and 100BaseTX Port Adapter Installation and Configuration that accompanies the hardware and the feature module in the Feature Guide for Cisco IOS Release 11.2 P.
New Software Features in Cisco IOS Release 11.2(10)P
The following new software features are supported by the Cisco 7000 family of routers for Cisco IOS Release 11.2(10)P:
Encryption over Frame Relay on VIP
You can use any type of encapsulation with IP encryption, except as follows: If you have a second-generation Versatile Interface Processor (VIP2) with a serial interface, encryption does not work for traffic on the serial interface unless you use the Point-to-Point Protocol (PPP), High-Level Data Link Control (HDLC) protocol, or Frame Relay protocol. For example, you cannot use encryption if you have X.25 or SMDS configured for the serial interface of a VIP2.
This feature was introduced in Cisco IOS Release 11.2(7)P. Encryption over Frame Relay on a VIP2 is available in Cisco IOS Release 11.2(7)P or a later release of 11.2 P.
POS Command Enhancements
The following commands have been added to support new features for the Packet-over-SONET (POS) interface:
•
•
Web Cache Communication Protocol
Using the Web Cache Communication Protocol (WCCP) feature you can use a Cisco Cache Engine to handle Web traffic, thus reducing transmission costs and downloading time. This traffic includes user requests to view pages and graphics on World Wide Web servers, whether internal or external to your network, and the replies to those requests.
When a user (client) requests a page from a Web server, the router sends the request to a Cisco Cache Engine. If the cache engine has a copy of the requested page in storage, the engine sends the user that page. Otherwise, the engine gets the requested page and the objects on that page from the Web server, stores a copy of the page and its objects (caches them), and forwards the page and objects to the user.
WCCP transparently redirects HTTP requests from the intended server to a Cisco Cache Engine. End users do not know that the page came from the cache engine rather than from the originally requested Web server.
The publication Using the Cisco Cache Engine contains detailed information about the Cisco Cache Engine and discusses alternative network configurations. For more information on WCCP, refer to the feature module in the Feature Guide for Cisco IOS Release 11.2 P.
New Features in Cisco IOS Release 11.2(9)P

Basic Rate Interface (BRI) Integrated Services Digital Network (ISDN) port adapters (PA-8B-ST and PA-4B-U) are available on Cisco 7200 series routers.
The PA-8B-ST port adapter provides up to eight S/T-type BRI interfaces used to connect to an ISDN wide-area network through an external network terminator 1 (NT1) device. The PA-4B-U provides up to four BRI interfaces used to connect to an ISDN wide-area network through its internal NT1 device. Each PA-8B-ST and PA-4B-U interface consists of two bearer (B) channels that can transmit and receive data at the rate of 64 kbps, full-duplex, and one data (D) channel that can transmit and receive data at the rate of 16 kbps, full-duplex. The interfaces use an RJ-45 receptacle and standard straight-through twisted-pair cable.
The B channels are used for transmitting user data. The D channel is used for call setup control and network connection teardown, and provides the communication from the router to the ISDN switch. The B and D channels are presented to the system as serial interfaces that support High-Level Data Link Control (HDLC) and Point-to-Point Protocol (PPP) encapsulation. The PA-8B-ST and PA-4B-U port adapters also support dial-on-demand routing (DDR).
Half-Duplex and Bisync for Synchronous Serial Port Adapters on Cisco 7200 Series Routers
The synchronous serial port adapters (PA-8T-V35, PA-8T-X21, PA-8T-232, and PA-4T+) on Cisco 7200 series routers support half-duplex and binary synchronous communications (Bisync). Bisync is a character-oriented data link layer protocol for half-duplex applications. In half-duplex mode, data is sent in one direction at a time. Direction is controlled by handshaking the Request To Send (RTS) and Clear To Send (CTS) control lines.
Next-Generation Route Switch Processor on Cisco 7500 Series Routers
The next-generation Route Switch Processor (RSP4) provides improved performance on Cisco 7500 series routers. The RSP4 uses a 200-MHz R5000 processor with twice the primary cache and a 512-KB secondary cache for greatly improved performance. The biggest increases in performance are in process-level switching and other process-level tasks (for example, route calculations), in which the RSP4 is between two and four times faster than an RSP2. Fast-switching performance is also improved. The RSP4 supports the high system availability (HSA) feature and can be used in combination with an RSP2 or another RSP4.

The PA-2CT1/PRI provides up to two channelized T1 interfaces to connect to CSUs, and can transmit and receive data bidirectionally at the T1 rate of 1.544 Mbps. The interfaces use a 15-pin, D-shell receptacle. The PA-2CE1/PRI-75 and PA-2E1/PRI-120 use G.703 serial interface cables, and the PA-2CT1/PRI uses standard serial cables (null-modem and straight-through).
Data Encryption Service Adapter
The data encryption service adapter (ESA) is available on Cisco 7500 series routers, Cisco 7200 series routers, and Cisco 7000 series routers with the 7000 Series Route Switch Processor (RSP7000) and 7000 Series Chassis Interface (RSP7000CI). The ESA requires a VIP2 model VIP2-40.
The ESA provides encryption processing to offload some of the encryption processing from the router's main processor and to improve performance. Encryption and authentication are provided by a software service called a crypto engine. The ESA provides the encryption mechanisms required to perform data encryption using a 40-bit or 56-bit Data Encryption Standard (DES) configured through the crypto engine. The ESA uses Public Key (PK) technology based on the concept of the Protected Entity (PE) and employs DES and the Digital Signature Standard (DSS) to ensure that secure data and information can be transferred between similarly equipped hosts on your network.
For detailed information on encryption, refer to the "Configuring Network Data Encryption with Router Authentication" chapter in the Security Configuration Guide.
New Software Features in Cisco IOS Release 11.2(7)P
The following new software features are supported by the Cisco 7000 family of routers for Cisco IOS Release 11.2(7)P:
Particle-Based Transparent Bridging on Cisco 7200 Series Routers
Particle-based transparent bridging (TRB) adds scatter-gather capability to transparent bridging by default to improve performance on Cisco 7200 series routers.
Particles represent a communications data packet as a collection of noncontiguous buffers. The traditional Cisco IOS packet has a packet-type control structure and a single, contiguous data buffer. A particle packet has the same packet-type control structure but also maintains a queue of particle-type structures, each of which manages its own block.
This scatter-gather architecture provides the following advantages:
•
•
•
Fast-Switched Fragmented IP Packets on Cisco 7200 Series Routers
Fragmented IP packets are now fast-switched rather than process-switched by default to improve performance on Cisco 7200 series routers.
Fast-Switched SMRP Packets on Cisco 7200 Series Routers
Simple Multicast Routing Protocol (SMRP) packets are now fast-switched rather than process-switched by default to improve performance on Cisco 7200 series routers.
Turbo Flooding of UDP Datagrams on Cisco 7200 Series Routers
Turbo flooding is now supported on Cisco 7200 series routers. Turbo flooding speeds up flooding of User Datagram Protocol (UDP) datagrams using the spanning-tree algorithm. This feature is useful for quickly downloading periodic updates from a server to multiple clients in an environment where updates are frequent and speed and latency are primary considerations.
Clock Rate Command Enhancements
The clock rate interface command has been enhanced for the synchronous serial port adapters (PA-8T-V35, PA-8T-X21, PA-8T-232, and PA-4T+) on Cisco 7500 series routers, Cisco 7200 series routers, and Cisco 7000 series routers with the 7000 Series Route Switch Processor (RSP7000) and 7000 Series Chassis Interface (RSP7000CI). For these port adapters, a nonstandard clock rate can be used. The clock rate you enter is rounded (if needed) to the nearest value that your hardware can support.

The CSA requires a VIP2 model VIP2-40.
These service adapters provide high-performance, hardware-based data compression capabilities through simultaneous Stacker compression data compression algorithms with independent full-duplex compression and decompression capabilities on Point-to-Point Protocol (PPP) encapsulated packets.
Channelized T3 Interface Processor
The Channelized T3 Interface Processor (CT3IP) is available on Cisco 7500 series routers and Cisco 7000 series routers with the 7000 Series Route Switch Processor (RSP7000) and 7000 Series Chassis Interface (RSP7000CI).
The CT3IP is a fixed-configuration interface processor based on the second-generation Versatile Interface Processor (VIP2). The CT3IP has four T1 connections through DB-15 connectors and one DS3 connection through BNC connectors. Each DS3 interface can provide up to 28 T1 channels (a single T3 group). Each channel is presented to the system as a serial interface that can be configured individually. The CT3IP can transmit and receive data bidirectionally at the T1 rate of 1.536 Mbps. The four T1 connections use 100-ohm, twisted-pair serial cables to external channel service units (CSUs) or to a MultiChannel Interface Processor (MIP) on the same router or on another router. For wide-area networking, the CT3IP can function as a concentrator for a remote site.
FDDI Full-Duplex Single-Mode and Multimode Port Adapters
Fiber Distributed Data Interface (FDDI) full-duplex single-mode and multimode port adapters (PA-F/FD-SM and PA-F/FD-MM) are available on Cisco 7500 series routers, Cisco 7200 series routers, and Cisco 7000 series routers with the 7000 Series Route Switch Processor (RSP7000) and 7000 Series Chassis Interface (RSP7000CI).
These port adapters provide an interface for both single-mode and multimode fiber-optic cable. Two physical ports are available with either single-mode SC-type or multimode MIC receptacles. Each port adapter's FDDI connection allows a maximum aggregate bandwidth of 200 Mbps per the FDDI standard.
High-Speed Serial Interface Port Adapters
The High-Speed Serial Interface (HSSI) port adapter (PA-H Rev. B) is available on Cisco 7500 series routers, Cisco 7200 series routers, and Cisco 7000 series routers with the 7000 Series Route Switch Processor (RSP7000) and 7000 Series Chassis Interface (RSP7000CI). The PA-H provides one high-speed synchronous serial interface.
Although the PA-H was introduced in Cisco IOS Release 11.2(5)P, the minimum Cisco IOS release required by the PA-H is Cisco IOS Release 11.2(7)P or Cisco IOS Release 11.1(12)CA.
For additional information on the PA-H and PA-2H (the PA-2H provides two high-speed synchronous serial interfaces) port adapters, refer to the Field Notice: PA-H and PA-2H Revised HSSI Port Adapters publication on Cisco.com at the following location:

New Software Features in Cisco IOS Release 11.2(5)P
The following new software features are supported by the Cisco 7000 family of routers for Cisco IOS Release 11.2(5)P:
RSP Fragmented IP Packets Optimum-Switched or Flow-Switched
To improve performance, fragmented IP packets are now optimum-switched or flow-switched (depending on which switching method is enabled) rather than being process-switched on Cisco 7500 series routers and Cisco 7000 series routers with the 7000 Series Route Switch Processor (RSP7000) and 7000 Series Chassis Interface (RSP7000CI).
Selective Packet Discard
When severely overloaded, routers that cannot keep up with the incoming packet stream must drop packets. If no intelligence is applied to choosing which ones to discard, the stability of routing protocols is impacted. This feature applies some simple choices to selectively discard packets likely to be unimportant for routing and interface stability. Selective Packet Discard (SPD) is enabled by default; there are no commands or configuration tasks required.
New Features in Cisco IOS Release 11.2(4)P
There are no new features supported by the Cisco 7000 family of routers for Cisco IOS Release 11.2(4)P.

Cisco IOS Release 11.2(15a) and 11.2(15a)P
After the release of Cisco IOS Release 11.2(15) and Release 11.2(15)P, a serious defect (caveat CSCdk33475) was identified that affects Enhanced IGRP for Cisco IOS Releases 11.2(14.1) through 11.2(15.2) and Cisco IOS Releases 11.2(14.1)P through 11.2(15.2)P. This defect was significant enough to merit a software rebuild. The rebuild includes the caveat fix and is renumbered to Cisco IOS Releases 11.2(15a) and Cisco IOS Release 11.2(15a)P.
Caveat CSCdk33475 causes a router to fail after the command show ip eigrp events is issued. Although this show command is not required for normal operation, it is used often enough by the Technical Assistance Center (TAC) personnel and customers causing major problems for customers who are running images with this defect. Cisco IOS Release 11.2(15a) and Cisco IOS Release 11.2(15a)P and all subsequent releases of Cisco IOS software, including Cisco IOS Release 11.2(16) and Cisco IOS Release 11.2(16)P, include the fix for this caveat.
Cisco IOS Release 11.2(13)P1 Reintroduces Caveat CSCdj79433
Cisco IOS Release 11.2(13)P was deferred because of a severe defect introduced by the fix for caveat CSCdj79433. A software rebuild removes the fix for CSCdj79433 and is renumbered to Cisco IOS Release 11.2(13)P1. This deferral applies to all images except RSP and RSM.
Some 40-Bit Encryption Images Are Unavailable
We are conducting an internal review of the build and distribution processes associated with 40-bit Cisco IOS cryptographic products. So that we may provide you with seamless access to Cisco IOS 40-bit encryption capability, we will provide access to the most current 40-bit encryption images, beginning with Cisco IOS Releases 11.2 (12), 11.2(12)P, and 11.3(2). The following 40-bit encryption images are indefinitely unavailable:

This review is not related to any new or previously unreported bugs. The information gathered in the review will be used to implement new automated development and order-processing applications.
Cisco IOS Release 11.2(12a)P Fixes Caveat CSCdj52309
The Cisco 7500 products in Cisco IOS software Cisco IOS Release 11.2(12)P were deferred because of a catastrophic defect. It was determined that this caveat was significant enough to merit a software rebuild. The rebuild includes the caveat fix and is renumbered to Cisco IOS Release 11.2(12a)P.
Caveat CSCdj52309: affects all Cisco 7500 and Catalyst 5000 RSM users. The problem occurs when packet tunneling is used in combination with certain timing conditions, packet sizes, and buffer usages. Affected images are being deferred and special images are being built.
Tunneling is being used as an abbreviation in this context to refer to a specific fast-switch to process-level code path traversed by translational (TLB), source route (SRB), and remote source-route bridging (RSRB).
When the packet tunneling logic on RSP or RSM-equipped systems causes datagrams to be copied from SRAM to DRAM, an arithmetic error results in more bytes being copied than are remembered for cleanup processing. Reuses of the tunneling logic, in certain rare combinations of timing, packet sizes, and buffer usages, may result in those unaccounted bytes causing several anomalous system behaviors, including packet errors.
This software defect is exposed to all RSP and RSM images in the following Cisco IOS software releases: 11.2, 11.2 P, 11.2 BC, 11.3, 11.3 T.
Solution: To eliminate the problems mentioned in the preceding section, we strongly recommend that you download and install one of the following Cisco IOS software release updates: 11.2(12a), 11.2(12a)P, 11.3(2a), 11.3(2a)T.
Workarounds: There are two possible workarounds. CSCdj33812 provides a configuration command to avoid the software defect. This workaround is available in the following Cisco IOS software releases: 11.2(11.5), 11.2(11.5)P, 11.2(11.5)BC, 11.3(2.1), and 11.3(2.1)T. If you are using an earlier release, use the second workaround.
The two workarounds will drop performance down to process-switching levels.
Workaround 1:
CSCdj33812 incorporated a configurable command that will be stored in NVRAM.
Configure with the memory cache-policy io uncached command to work around CSCdj52309. To determine what memory cache policies are currently configured on your router, use the show rsp command.
Router# configure terminal Enter configuration commands, one per line. End with CNTL/Z.

The above command needs to be entered after every reload.
Other considerations: Cisco IOS Releases 10.3, 11.0, and 11.1 major and early deployment (ED) releases are not exposed to CSCdj52309. Though these releases share the same arithmetic problem, the tunneling software is different, and there is no known or predicted combination of timing, packet sizes, and buffer usages that results in the same or different anomalous behaviors associated with Cisco IOS Releases 11.2, 11.2 P, 11.2 BC, 11.3 and 11.3 P. Cisco is using CSCdj52309 to repair the arithmetic problem in Cisco IOS Releases 10.3, 11.0, and 11.1; however, no special images are being created because the anomalous behaviors are not present in those releases. [CSCdj52309]
Cisco IOS Release 11.2(12a)P and all subsequent releases of Cisco IOS software include the fix for this caveat.
Cisco IOS Release 11.2(7a)P
Cisco IOS Release 11.2(7a)P is an early deployment release of software to support Cisco 7200 series routers. Cisco IOS Release 11.2(7a)P is the same as Cisco IOS Release 11.2(7)P except the following defects have been resolved in Cisco IOS Release 11.2(7a)P—CSCdj24132 and CSCdj19118.
Cisco IOS Release 11.2(6)P2
Cisco IOS Release 11.2(6)P2 is an early deployment release of software to support Cisco 7200 series routers, Cisco 7500 series routers, and Cisco 7000 series routers with the RSP7000 and RSP7000CI. Cisco IOS Release 11.2(6)P2 is the same as Cisco IOS Release 11.2(6)P except the following defects have been resolved in Cisco IOS Release 11.2(6)P2—CSCdj060068, CSCdj10028, CSCdj19231, and CSCdi67315. Cisco IOS Release 11.2(6)P and Cisco IOS Release 11.2(6)P1 software images were not released.
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.
This section contains only open and resolved caveats for the current Cisco IOS maintenance release.
For information on caveats in Cisco IOS Release 11.2(26)P, see the Caveats for Cisco IOS Release 11.2 P.
All caveats in Cisco IOS Release 11.2 are also in Cisco IOS Release 11.2 P.
For information on caveats in Cisco IOS Release 11.2, see the "Caveats" section in the Cross-Platform Release Notes for Cisco IOS Release 11.2 which lists severity 1 and 2 caveats. The Cross-Platform Release Notes for Cisco IOS Release 11. 2 is located on Cisco.com and the Documentation CD-ROM.
