Release Notes for Cisco IOS Release 11.2 P
June 30, 1997
These release notes describe the features and caveats for Cisco IOS Release 11.2 P, up to and including Release 11.2(7)P. Specific routers and access servers are affected by this software release. For detailed software configuration information on the new access server and router features and Cisco IOS commands supported by Release 11.2 P, refer to the Feature Guide for Cisco IOS Release 11.2 P.
This release note will no longer be updated with maintenance release information. As of Release 11.2(8)P, release notes are product specific. That is, there are separate release notes for each product line rather than one release note that covers all products. Refer to the particular product's release note for information about the release. For example, for information about Cisco 2500 series, refer to the Release Notes for the Cisco 2500 Series for Cisco IOS Release 11.2.
Prior to Cisco IOS Release 11.2, maintenance releases of major Cisco IOS software releases were used to deliver additional new features. Beginning with Cisco IOS Release 11.2, Cisco Systems provides as many as three software release "trains" based on a single version of Cisco IOS software. Maintenance releases of the Major train software deliver fixes to software defects only, thus providing the most stable software for your network, for the features you need.
In addition to the Major train, there are up to two Early Deployment (ED) trains. One ED train—Release 11.2 P—delivers both fixes to software defects and support for new Cisco platforms. The other ED train—Release 11.2 F—delivers fixes to software defects, new platform support, and new cross-platform functionality.
These release notes do not describe features that are available in Release 11.2 or Release 11.2 F. For information about features in Release 11.2, refer to the Release Notes for Cisco IOS Release 11.2. For information about features in Release 11.2 F, refer to the Release Notes for Cisco IOS Release 11.2 F.
Use these release notes in conjunction with the Release Notes for Cisco IOS Release 11.2. The software caveats that apply to Release 11.2 also apply to Release 11.2 P.

New Features in Release 11.2(7)P
The following new features are supported by Cisco IOS Release 11.2(7)P.
Cisco 3800
Cisco 3800 is a scalable access solution that combines switched voice, multiprotocol data and routing in one powerful access device. By integrating switching and routing technology onto a single card the Cisco 3800 significantly reduces communications costs. Switched voice, multiprotocol data, and routed traffic can be combined over Frame Relay, leased line, or T1/E1 ATM access lines for delivery over public Frame Relay or ATM services, or on Cisco's StrataCom IGX or BPX ATM backbone switches.
For more information on the Cisco 3800, refer to the Cisco 3800 Series Product Release Notes (documentation part number 78-4205-04).
Catalyst 5000 Route Switch Module (RSM)
The Catalyst 5000 RSM is a RSP2 class router blade for the Catalyst 5000 family of switches. The RSM provides high-performance, multilayer switching and routing services between switched Virtual LANs (VLANs) and emulated LANs (ELANs). Initial protocol support includes IP, IPX, appletalk, and DECnet.
For more information on the Catalyst 5000 RSM refer to the Cisco 5000 Series Switch Route Switch Module Installation and Configuration Note (documentation part number 78-4058-01).
16-Port and 32-Port Asynchronous Network Modules for Cisco 3600 Series Routers
Cisco 3600 series routers now support 16- and 32-port network modules for asynchronous connections. These devices are high density modules that support speeds up to 134.4 kbps. Depending on which module you install in the router, you can have up to 16 or 32 modem connections to each module at any given time. The Cisco 3640 can support up to 96 dialin ports.
56K 12-Port Modem Modules for the Cisco AS5200 Access Server
The Cisco AS5200 universal access server now supports digital modem cards, which are software upgradeable to 56K modems (K56flex) with modem firmware 3.1.x and beyond.
Digital modems are used for making high-speed connections across digital networks. Ultimately, this means that files transmitted up to 56 kbps arrive at the desktop at nearly twice the speed of standard V.34 (28.8-kbps) connections. The wait for information is reduced by nearly 50 percent.
56K modems are ideal for serious Internet users who want to quickly dial in to corporate LANs or download web pages containing sound, video, graphics, and other large files over digital networks using standard telephone lines.
Note
Compression Network Module for Cisco 3600 Series Routers
Cisco 3600 series routers now support a compression port module that provides high-performance, hardware-based data compression using simultaneous Stacker compression algorithms. Independent full-duplex compression and decompression capabilities are used on point-to-point (PPP) encapsulated packets.
A router's central processing unit is generally reserved for tasks such as creating and maintaining routing tables, not performing compression duties. When a hardware compression port module is used in a router, all compression activity is offloaded from the router's central processing unit. This kind of hardware configuration is needed for routers that require B-channel compression for multiple WAN connections, such as two ISDN PRI interfaces carrying 46 B channels. Signaling over the D channel is not compressed. One compression port module supports up to 128 WAN interfaces.
PA-8B-ST and PA-4B-U Basic Rate Interface Port Adapters
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 one direction at a time. Direction is controlled by handshaking the RTS and CTS control lines.
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 router.
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.
Next-Generation Route Switch Processor (RSP4) 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 to greatly improve performance. The biggest increases in performance are in process-level switching and other process-level tasks (for example, route calculations) where 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.
Packet OC-3 Interface Processor
The Packet OC-3 Interface Processor (POSIP) is available on Cisco 7000 series routers with the 7000 Series Route Switch Processor (RSP7000) and 7000 Series Chassis Interface (RSP7000CI) and on Cisco 7500 series routers.
The POSIP is a fixed-configuration interface processor that uses second-generation Versatile Interface Processor (VIP2) technology. The POSIP provides a single 155.520-Mbps, OC-3 physical layer interface for packet-based traffic. This OC-3 interface is fully compatible with SONET and Synchronous Digital Hierarchy (SDH) network facilities and is compliant with RFC 1619, "PPP over SONET/SDH," and RFC 1662, "PPP in HDLC-like Framing." The Packet-Over-SONET specification is primarily concerned with the use of the PPP encapsulation over SONET/SDH links.
Channelized T3 Interface Processor Feature Enhancements
You can now perform the following new tasks on the Channelized T3 Interface Processor (CT3IP) available on Cisco 7500 series routers, and on Cisco 7000 series routers with the 7000 Series Route Switch Processor (RSP7000) and 7000 Series Chassis Interface (RSP7000CI):
•
•
•
•
•
100VG-AnyLAN Port Adapter
The 100VG-AnyLAN port adapter (PA-100VG) is available on Cisco 7200 series routers, Cisco 7500 series routers, and on Cisco 7000 series routers with the 7000 Series Route Switch Processor (RSP7000) and 7000 Series Chassis Interface (RSP7000CI).
The PA-100VG provides a single interface compatible with and specified by IEEE 802.12 to support 100 Mbps over Category 3 or Category 5 unshielded twisted-pair (UTP) cable with RJ-45 terminators. The PA-100VG supports 802.3 Ethernet packets and can be monitored with the IEEE 802.12 Interface MIB.
PA-4R-FDX Token Ring Full-Duplex Port Adapter
The Token Ring full-duplex port adapter (PA-4R-FDX) 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-4R-FDX provides up to four IBM Token Ring or IEEE 802.5 Token Ring interfaces that can be set for 4- or 16-Mbps half-duplex or full-duplex operation and early token release. The default for all interfaces is half-duplex 4-Mbps operation with early token release disabled. The PA-4R-FDX connects over Type 1 lobe or Type 3 lobe cables and provides a DB-9 (PC-type) receptacle.
PA-A1-OC3MM and PA-A1-OC3SM ATM Port Adapters
Asynchronous Transfer Mode (ATM) port adapters (PA-A1-OC3MM and PA-A1-OC3SM) are available on Cisco 7200 series routers, on the second-generation Versatile Interface Processor (VIP2) in Cisco 7500 series routers, and in Cisco 7000 series routers with the 7000 Series Route Switch Processor (RSP7000) and 7000 Series Chassis Interface (RSP7000CI).
The ATM port adapter provides a single SONET/SDH OC-3 full-duplex interface (either multimode or single-mode intermediate reach) and supports data rates of up to 155 Mbps bidirectionally. The ATM port adapter connects to a SONET/SDH multimode or SONET/STC-3C single-mode optical fiber cable (STS-3C or STM-1 physical layer) to connect the router to an external DSU (an ATM network). The ATM port adapter supports the following features:
•
•
•
•
•
PA-2CE1/PRI-75, PA-2CE1/PRI-120, and PA-2CT1/PRI Channelized E1 and T1 Port Adapters
Channelized E1 and T1 Primary Rate Interface (PRI) Integrated Services Digital Network (ISDN) port adapters (PA-2CE1/PRI-75, PA-2CE1/PRI-120, and PA-2CT1/PRI) are available on Cisco 7200 series routers, Cisco 7500 series routers, and on Cisco 7000 series routers with the 7000 Series Route Switch Processor (RSP7000) and 7000 Series Chassis Interface (RSP7000CI).
The PA-2CE1/PRI-120 (balanced 120 ohm) and PA-2E1/PRI-75 (unbalanced 75 ohm) provide up to two channelized E1 interfaces to connect to channel service units (CSUs), and can transmit and receive data bidirectionally at the E1 rate of 2.048 Mbps. 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 7200 series routers, on the second-generation Versatile Interface Processors (VIP2-40 specifically) in Cisco 7500 series routers, and on the VIP2-40 in Cisco 7000 series routers with the 7000 Series Route Switch Processor (RSP7000) and 7000 Series Chassis Interface (RSP7000CI). (ESAs require 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 the DES and the Digital Signature Standard (DSS) to ensure 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.
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 7200 series routers, on second-generation Versatile Interface Processors (VIP2s) in Cisco 7500 series routers, and on 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.
New Features in Release 11.2(6)P
The following new features are supported by Cisco IOS Release 11.2(6)P. Because each of these features do not require new or modified software configuration information, no additional feature chapters for Release 11.2(6)P are included in the Feature Guide for Cisco IOS Release 11.2 P.
Cisco 2500 Fixed FRAD Series
Cisco Systems is introducing three new models in the Cisco 2500 series that are preconfigured as Frame Relay access devices (FRADs). The devices include the Cisco 2501FRAD-FX, Cisco 2501LANFRAD-FX, and Cisco 2502LANFRAD-FX. These new "Fixed FRADs" complement the existing Cisco 2500 serial and LAN FRAD models and offer a new entry point for cost-effective Frame Relay applications. The Fixed FRADs are ideal for branch office and remote office connectivity of legacy/ System Network Architecture (SNA) devices or cost-effective Frame Relay access.
Mission-specific routers are entry-level routers that are based on standard Cisco 2500 series hardware. However, mission-specific routers contain less memory than standard models and run reduced software images designed for CFRAD, LAN FRAD, and ISDN applications. The Cisco 2500 series fixed FRAD platforms are a variation of the Mission-specific CFRAD and LAN FRAD platforms. However, they are not upgradeable to routers like the mission-specific FRAD models.
The Cisco Fixed FRADs have been modified so that they will not execute non-FRAD Cisco IOS software images. This includes the images designed for other Cisco 2500 series systems. The Fixed FRAD routers cannot be upgraded to run feature sets that typically run on Cisco 2500 series routers.
The Fixed FRAD series includes three fixed-configuration hardware models with the following features:
•
•
•
Generated SysObjectID's
The Generated SysObjectID's feature generates a unique sysObjectID for each Cisco 2500 series router and its derived partner product. For example, the sysObjectID values for a Cisco 2511, a partner's 2511, and another partner's 2511 will each be different. The sysObjectID SNMP MIB object is used to identify the device to be managed and make application-specific decisions. In some network management programs, this object determines which graphical element or name to display for a device.
Fast Ethernet for the Cisco 3600 Series Routers
The Fast Ethernet network module provides a single interface that supports 100BaseT and 10BaseT connectivity. There is one RJ-45 10/100 port on the Fast Ethernet network module. This port enables autonegotiation of the peers' capabilities and configure itself to support the highest possible data rate.
New Features in Release 11.2(5)P
The following hardware platforms are supported by Cisco IOS Release 11.2(5)P.
Cisco 1600 Series Routers
The Cisco 1600 series of access routers deliver the next-generation set of features and benefits for small-office Internet and intranet access: WAN flexibility, end-to-end security, end-to-end quality of service, ease of use, deployment, and management. Cisco 1600 series routers connect small offices with Ethernet LANs to the public Internet and to a company's internal intranet or corporate LAN through several WAN connections such as ISDN, asynchronous serial, and synchronous serial. Cisco 1600 series routers include the following models: the Cisco 1601, Cisco 1602, Cisco 1603, and Cisco 1604.
All Cisco 1600 series models include one Ethernet port, one built-in WAN port, and one WAN interface card expansion slot for additional connectivity and flexibility. The Cisco 1601 includes a built-in serial WAN port; the Cisco 1602 has an onboard 56-kbps four-wire channel service unit/data service unit (CSU/DSU); the Cisco 1603 has an ISDN BRI S/T port; and the Cisco 1604 includes an ISDN BRI U interface with a built-in NT1 device.

The Cisco AS2509-RJ and Cisco AS2511-RJ access servers connect asynchronous serial devices to LANs and WANs. The access servers combine the functions of a terminal server, protocol translator, and a router, and perform both synchronous and asynchronous routing of supported protocols.
These access servers provide the following interfaces and ports:
•
•
•
•
•
Cisco 3600 Series Routers
The Cisco 3600 series includes the Cisco 3640 and Cisco 3620 routers. As modular solutions, the Cisco 3640 and Cisco 3620 enable corporations to increase dialup density and take advantage of current and emerging WAN technologies and networking capabilities. The Cisco 3600 series is fully supported by the Cisco IOS software, which includes dialup connectivity, LAN-to-LAN routing, data and access security, WAN optimization, and multimedia features.
The Cisco 3640 has four network module slots; the Cisco 3620 has two slots. Each network module slot accepts a variety of network module interface cards, including LAN and WAN mixed media cards supporting Ethernet, Token Ring, and a variety of WAN technologies. These cards provide the foundation of LAN and WAN connectivity on a single modular network module. Additional applications are supported with a series of network module cards offering asynchronous and synchronous serial, ISDN PRI, and ISDN BRI interfaces.
lists the WAN interface cards supported by the Cisco 3600 series routers.
Table 5 Supported WAN Interface Cards and Network Modules

2 The 4-port module is not upgradeable to the 8-port module.
Channelized E1 Signaling for the Cisco AS5200
The Cisco AS5200 universal access server now supports channel-associated signaling for channelized E1 lines, which are commonly deployed in networks in Latin America, Asia, and Europe.
After this feature is configured on a single E1 controller, up to 30 remote users can simultaneously dial in to the Cisco AS5200 through networks running the R2 protocol. Typically, all 30 channels of an channelized E1 line are used for analog calls. However, a signal converter is still needed to perform conversions between R2 signaling and ear and mouth signaling (also known as E&M). Because the Cisco AS5200 has two physical E1 ports on its dual E1 PRI board, up to 60 simultaneous connections can be made through the dual E1 PRI board.
High-Speed Serial Interface Network Processor Module for Cisco 4000 Series Routers
A High-Speed Serial Interface (HSSI) network processor module (NPM) is a high-speed and high-bandwidth serial interface device that is inserted into a vacant chassis slot on Cisco 4000 series routers. The HSSI NPM supports full-duplex and data rates up to 52 Mbps.
There are many network applications for the HSSI NPM. For example, medium-sized Internet service providers can use this module to connect to an Internet backbone provider via a T3 or E3 line. It can also be used for campus-to-campus high-speed serial connections.
SA-Comp/1 and SA-Comp/4 Data Compression Service Adapters
The SA-Comp/1 and SA-Comp/4 data compression service adapters (CSAs) are available on Cisco 7200 series routers, on second-generation Versatile Interface Processors (VIP2s) in Cisco 7500 series routers, and on Cisco 7000 series routers with the 7000 Series Route Switch Processor (RSP7000) and 7000 Series Chassis Interface (RSP7000CI). (CSAs require VIP2 model VIP2-40.)
These service adapters provide high-performance, hardware-based data compression capabilities via 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 via DB-15 connectors and one DS3 connection via 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 7200 series routers, on second-generation Versatile Interface Processors (VIP2s) in Cisco 7500 series routers, and on 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 adapters (PA-H and PA-2H) are available on Cisco 7200 series routers, on second-generation Versatile Interface Processors (VIP2s) in Cisco 7500 series routers, and on 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, and the PA-2H provides two high-speed synchronous serial interfaces.
Synchronous Serial Port Adapters
The synchronous serial port adapters (PA-8T-V35, PA-8T-X21, PA-8T-232, and PA-4T+) are available on Cisco 7200 series routers, on second-generation Versatile Interface Processors (VIP2s) in Cisco 7500 series routers, and on Cisco 7000 series routers with the 7000 Series Route Switch Processor (RSP7000) and 7000 Series Chassis Interface (RSP7000CI).
The PA-8T-V35, PA-8T-X21, PA-8T-232 port adapters provide up to eight synchronous serial interfaces, and the PA-4T+ provides up to four synchronous serial interfaces. Each port on the PA-4T+ supports any of the available interface types: Electronics Industries Association/Telecommunications Industries Association (EIA/TIA)-232, EIA/TIA-449, V.35, X.21, and EIA-530.
RSP Fragmented IP Packets Optimum or Flow Switched
To improve performance, fragmented IP packets are now optimum or flow switched (depending which switching method is enabled) rather than being process switched on Cisco 7500 series routers and on Cisco 7000 series routers with the 7000 Series Route Switch Processor (RSP7000) and 7000 Series Chassis Interface (RSP7000CI).
Selective Packet Discard (SPD)
When in severe overload conditions, routers that cannot keep up with the incoming packet stream must drop packets. If no intelligence is applied to choosing which ones to discard, this will impact the stability of routing protocols. This feature applies some simple choices to selectively discard packets likely to be unimportant for routing and interface stability. SPD is enabled by default; there are no commands or configuration tasks required.
New Features in Release 11.2(4)P
The following software features have been added to Release 11.2(4)P.
Internet Router Cards for 10BaseT Hubs

Important Notes
This section contains important information about the Cisco IOS Release 11.2 P software. The following information describes the changes in release number for Release 11.2 P:
•
Release 11.2(6)P2 is the same as Release 11.2(6)P except the following defects have been resolved in Release 11.2(6)P2: CSCdj060068, CSCdj10028, CSCdj19231, and CSCdi67315.
Release 11.2(6)P and Release 11.2(6)P1 software images for the Cisco 7000 series with RSP7000, Cisco 7500 series, and Cisco 7200 series routers was not released.
Release 11.2(7)P Caveats
This section describes possibly unexpected behavior by Cisco IOS Release 11.2(7)P. Unless otherwise noted, these caveats apply to all 11.2 P releases up to and including Release 11.2(7)P.

For additional caveats applicable to Release 11.2(6)P, see the caveats sections for newer 11.2 P releases. The caveats for newer releases precede this section.
All the caveats listed in this section are resolved in Release 11.2(7)P.

%RSP-3-RESTART: interface Serial12/0/0:28, output stuck %RSP-3-RESTART: interface Serial12/0/0:6, output stuck %RSP-3-RESTART: interface Serial12/0/0:12, output stuck %RSP-3-RESTART: interface Serial12/0/0:2, output stuckThis is a result of a internal timer utility that can incorrectly return a false value under extreme interrupt situations, which causes the transmit-buffers backing-store mechanism to falsely declare serial interface "output stuck."
Conditions—The symptom occurs on Cisco 7000 family routers using the CT3, 4/8 port FSIP cards, or any serial interface under Cisco IOS Release 11.1(10)CA, 11.1(11), and 11.2. It is only observed under oversubscribed traffic load conditions.
Workaround—Configure the interface to FIFO queueing using the no fair-queue command.
The command transmit-buffers backing-store is ON by default when an interface is configured for weighted fair-queueing. If the interface command no fair-queue is used, which changes the queueing strategy to FIFO, the transmit-buffers backing-store is OFF by default. [CSCdj12815]
•
For those customers running Release 11.2 P, we highly recommend upgrading all RSP-based systems to Cisco IOS Release 11.2(6)P or later. For those systems that cannot upgrade, this problem can be avoided by disabling both backing-store and fair queuing. See the instructions for this at the end of this message.
When packet load on RSP-equipped systems causes datagrams to be forwarded from SRAM to DRAM (a function of backing-store) 32 bytes of data may be randomly written into DRAM. This could result in several anomalous system behaviors including software-induced system crashes, dropped datagrams, and other anomalous errors.
SOLUTION:
FOR CUSTOMERS WITH CISCO IOS RELEASE 11.2 P
Option 1: We highly recommends the installation of Release 11.2(6)P or later for 11.2(x)P images.
This problem was fixed as bug CSCdi71609 in images 10.3 through 11.2. Unfortunately it was reintroduced as a result of merged code in Release 11.2 P only.
Option 2: Following are options to work around this bug.
Disable backing-store and fair queuing on each interface with the following IOS commands:
no transmit-buffers backing-store
no fair-queueAlso disable udp-turbo flooding if the image is Release 11.0 or later. The Cisco IOS command to disable UDP turbo flooding is no ip forward-protocol turbo-flood, which is OFF by default in all releases.
However, it is important to look at the current configuration. An image configured before backing-store defaulted to OFF may have it ON for router interfaces. [CSCdj19231]

The workaround is to have the FDDI FDX port adapter only in one VIP2 and leave the other bay empty. [CSCdj11249]

This is fixed in CT3 firmware version 2.2.0. To determine your current CT3 firmware version, use the show cont t3 EXEC command:
CT3 H/W Version: 5, CT3 ROM Version: 1.2, CT3 F/W Version: 2.2.0 ^^^^^
You must have version 2.2.0 or greater to use line clocking on T1 #23. Other T1s are not affected. [CSCdj18588]

The traffic pattern that caused this had to be "incrementing Destination Address" generated by an Ethernet sniffer.
