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. lists the current microcode versions for the Cisco 7000 family of routers.

New and Changed Information
The following sections list the new features supported by the Cisco 7000 family of routers in Cisco IOS Release 11.3 T.
There are no new features supported by the Cisco 7000 family in Cisco IOS Release 11.3(5)T and later releases of 11.3 T.
New Hardware Features in Release 11.3(4)T
The following new hardware features are supported by the Cisco 7000 family of routers in Cisco IOS Release 11.3(4)T. For easy online access, these feature descriptions are linked to the applicable Cisco IOS feature module if one exists. Click on the link to open the feature module.
PA-2FEISL 100BaseT Fast Ethernet/ISL Port Adapters
The PA-2FEISL 100BaseT Fast Ethernet/Inter-Switch Link (ISL) port adapters (PA-2FEISL-TX and PA-2FEISL-FX) are available for the Cisco 7200 series routers for the second-generation VIP2-15, VIP2-20, and VIP2-40 in all Cisco 7500 series routers, for Cisco 7000 series routers with the Cisco 7000 Series Route Switch Processor (RSP7000) and Cisco 7000 Series Chassis Interface (RSP7000CI).
The 2FEISL-TX or 2FEISL-FX port adapter provides two 100-Mbps, 100BaseT Fast Ethernet/ISL interfaces for VLAN transport over switch-to-switch backbone connections or switch-to-server data center attachments. These port adapters provide an inter-VLAN bridging and routing functionality that network administrators can use to deploy 100-Mbps Token Ring VLAN transport, 100-Mbps Ethernet VLAN transport, and bridging or routing between the mixed LAN types using the same physical ISL trunk links. Both full-duplex and half-duplex operation are supported for the 2FEISL-TX and 2FEISL-FX port adapters. For more information on the PA-2FEISL port adapters, refer to the publication PA-2FEISL 100BaseT Fast Ethernet/ISL Port Adapter Installation and Configuration.
New Software Features in Release 11.3(4)T
The following new software features are supported by the Cisco 7000 family of routers in Cisco IOS Release 11.3(4)T. For easy online access, these feature descriptions are linked to the applicable Cisco IOS feature module if one exists. Click on the link to open the feature module.
IP Type of Service and Precedence for GRE Tunnels
Before this feature, at generic route encapsulation-based tunnel endpoints, the type of service (ToS) bits (including precedence bits) were not copied to the tunnel or GRE IP header that encapsulates the inner packet. Instead, those bits were set to zero. This was not a problem unless the intermediate routers between two tunnel endpoints honored ToS or precedence bits, in which case those settings were ignored.
With the advent of virtual private network (VPN) and QoS (quality of service) applications, it is desirable to copy the ToS bits when the router encapsulates the packets using GRE. Thus, intermediate routers between tunnel endpoints can take advantage of the QoS features such as weighted fair queuing (WFQ) and weighted random early detection (WRED).
PPP over Frame Relay
PPP over Frame Relay allows a router to establish end-to-end Point-to-Point (PPP) sessions over Frame Relay. IP datagrams are transported over the PPP link using RFC 1973-compliant Frame Relay framing. This feature is useful for remote users running PPP to access their Frame Relay corporate networks.
Token Ring Inter-Switch Link
The Token Ring Inter-Switch Link (TRISL) feature is a Cisco protocol for interconnecting multiple routers and switches and maintaining VLAN information as traffic goes between routers and switches. The TRISL feature provides a method to transport native Token Ring frames from multiple VLANs across a 100-Mbps Fast Ethernet link.
The TRISL feature provides the following new functions for routers and switches:
•
•
New Hardware Features in Release 11.3(3)T
The following new hardware features are supported by the Cisco 7000 family of routers in Cisco IOS Release 11.3(3)T. For easy online access, these feature descriptions are linked to the applicable Cisco IOS feature module if one exists. Click on the link to open the feature module.
PA-4R-DTR Dedicated Token Ring Port Adapter
The Dedicated Token Ring port adapter (PA-4R-DTR) 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-DTR provides up to four IBM Token Ring or IEEE 802.5 Token Ring interfaces. Each Token Ring interface can be set for 4-Mbps or 16-Mbps half-duplex or full-duplex operation and can operate as a standard Token Ring station or as a concentrator port. The default for all interfaces is Token Ring station mode with half-duplex, 16-Mbps operation. The PA-4R-DTR connects over Type 1 lobe or Type 3 lobe cables, with each interface providing an RJ-45 receptacle.
Channel Port Adapter
The Channel Port Adapter (CPA) expands the value of Cisco's Channel Interface Processor (CIP) solution. The CIP continues to be the industry's premier high-performance mainframe channel connect router. The CPA extends the CIP architecture to customers requiring mid-range mainframe channel connectivity.
Note
The CPA is a standard single-width port adapter supporting Enterprise System Connection (ESCON) or parallel (also known as "bus and tag") channel interfaces to IBM and IBM-compatible mainframes.
The CPA comes with a default of 16 MB of RAM. Customers may upgrade to 32 MB of RAM either at the Cisco factory before the CPA is shipped or as a field upgrade after the CPA has been installed.
The only difference between channel software applications (Internet Protocol [IP] Datagram, Cisco Systems Network Architecture [SNA], TCP/IP Offload, TN3270 Server, and Cisco Multi-Path Channel [CMPC]) running on the CIP and CPA is performance. The CIP typically has higher performance and capacity than the CPA because the CIP has more memory (128 MB of RAM compared to 32 MB for the CPA) and a faster internal bus (64-bit bus compared to the 32-bit bus on the CPA).
RJ-45 Interface Support
Cisco 7200 series routers support a new I/O controller with an RJ-45 interface. The optional Fast Ethernet port is configurable for use at 100-Mbps full-duplex or half-duplex operation (half-duplex is the default). The Fast Ethernet port is equipped with either a single MII receptacle or an MII receptacle and an RJ-45 receptacle.
To support this new feature, the media-type interface command has been modified. The media-type interface command now supports two options:

Note
New Software Features in Release 11.3(3)T
The following new software features are supported by the Cisco 7000 family of routers in Cisco IOS Release 11.3(3)T. For easy online access, these feature descriptions are linked to the applicable Cisco IOS feature module if one exists. Click on the link to open the feature module.
Always on/Dynamic ISDN (AO/DI)
Always on/Dynamic ISDN (AO/DI) is an on-demand service that optimizes the use of an existing Integrated Services Digital Network (ISDN) signaling channel (D channel) to transport X.25 traffic. The X.25 D channel call is placed from the subscriber to the packet data service provider. Multilink and TCP/IP protocols are encapsulated within the X.25 logical circuit carried by the D channel. The bearer channels (B channels) use the Multilink protocol without the standard Q.922 and X.25 encapsulations, and invoke additional bandwidth as needed. AO/DI takes full advantage of existing packet handlers at the central office by using an existing D channel to transport the X.25 traffic. The link associated with the X.25 D channel packet connection is used as the primary link of the Multilink protocol. The D channel is a connectionless, packet-oriented link between the customer premises equipment (CPE) and the central office. Since the D channel is always available, it is possible to in turn offer "always available" services. On-demand functionality is achieved by using the B channels to temporarily boost data throughput. The B channels are disconnected after use.
Multiple ISDN Switch Types
The Multiple ISDN Switch Types feature allows you to configure more than one ISDN switch type per router. You can apply an ISDN switch type on a per interface basis, thus extending the existing global isdn switch-type command to the interface level. This allows Basic Rate Interfaces (BRI) and Primary Rate Interfaces (PRI) to run simultaneously on platforms that support both interface types.
The isdn tei command is also extended to the interface level. Terminal endpoint negotiation (TEI) determines when Layer 2 is activated (power up or first-call).
National ISDN Switch Types for Basic Rate and Primary Rate Interfaces
National ISDN Switch Types for Basic Rate and Primary Rate Interfaces introduces changes to ISDN switch types for PRI and BRI as follows:
•
•
•
•
•
•
Note
Microsoft Point-to-Point Compression (MPPC)
Microsoft Point-to-Point Compression (MPPC) is a scheme used to compress Point-to-Point Protocol (PPP) packets between Cisco and Microsoft client devices. The MPPC algorithm is designed to optimize processor and bandwidth utilization to support multiple simultaneous connections. The MPPC algorithm uses a Lempel-Ziv (LZ)-based algorithm with a continuous history buffer, called a dictionary.
VPDN MIB and Syslog Facility
The Virtual Private Dialup Network (VPDN) Management Information Base (MIB) feature is intended to support all the tables and objects defined in "Cisco VPDN Management MIB" for the user sessions of the VPDN features. A number of commands provide information and statistics through the command line interface (CLI) but not Simple Network Management Protocol (SNMP); the Cisco VPDN MIB has been created to satisfy the need to provide information and statistics through SNMP.
RIF Passthru in DLSw+
By default, data-link switching (DLSw+) terminates the Routing Information Field (RIF) for Token Ring, terminates the Logical Link Control (LLC) for all media types, and forwards only data across a WAN with DLSw+ and TCP/IP headers. The RIF is a field in source-route bridged frames that indicates the source-route bridging (SRB) path the frame should take when traversing a Token Ring network. In the case of an explorer packet, the RIF is a field of the source-route bridged frame that indicates the SRB path that the SRB explorer has traversed so far. The RIF is limited to seven hop counts by IBM standards. Because DLSw+ terminates the RIF at the virtual ring, the network's scalability increases because the hop count of the packet starts over, and the packet can traverse seven additional hops. Also, RIF termination simplifies network design because ring numbers no longer have to be unique throughout an entire enterprise.
However, some environments do not function properly if the RIF is terminated. For that reason, DLSw+ now supports the RIF Passthru feature, in which the entire source-route bridged path appears in the RIF.
Certification Authority Interoperability
Certification Authority (CA) interoperability is provided in support of the IP Security (IPSec) standard. CA interoperability permits Cisco IOS devices and CA devices to communicate so that your Cisco IOS device can obtain and use digital certificates from the CA. Although IPSec can be implemented in your network without the use of a CA, using a CA provides manageability and scalability for IPSec.
For background and configuration information for IPSec, see the "IPSec Network Security" feature documentation.
IPSec Network Security
IPSec is a framework of open standards developed by the Internet Engineering Task Force (IETF). IPSec provides security for transmission of sensitive information over unprotected networks such as the Internet. IPSec acts at the network layer, protecting and authenticating IP packets between participating IPSec devices ("peers") such as Cisco routers.
IPSec provides the following network security services:
•
•
•
•
With IPSec, data can be transmitted across a public network without fear of observation, modification, or spoofing. This secure data transmission allows applications such as virtual private networks (VPNs), extranets, and remote user access.
IPSec services are similar to those provided by Cisco Encryption Technology (CET), a proprietary security solution introduced in Cisco IOS Software Release 11.2. (The IPSec standard was not yet available at Release 11.2.) However, IPSec provides a more robust security solution, and is standards-based.
Internet Key Exchange Security Protocol
Internet Security Association & Key Management Protocol (ISAKMP)/Oakley is a key management protocol that is used in conjunction with the IPSec standard. IPSec is an IP security feature that provides robust authentication and encryption of IP packets. IPSec can be configured without ISAKMP/Oakley, but ISAKMP/Oakley enhances IPSec by providing additional features, flexibility, and ease of configuration for the IPSec standard.
ISAKMP/Oakley is a hybrid protocol that implements the Oakley key exchange inside the ISAKMP framework.
Automated Double Authentication
The automated double authentication feature enhances the existing double authentication feature.
Previously, with the existing double authentication feature, a second level of user authentication is achieved when the user Telnets to a network access server or router and enters a username and password. Now, with automated double authentication, the user does not have to Telnet anywhere but instead responds to a dialog box that requests a username and password or PIN.
(For information about the existing double authentication feature, refer to the "Configuring Authentication" chapter of the Cisco IOS Release 11.3 Security Configuration Guide.)
NFAS with D Channel Backup
The DMS100 and NI2 switch types have been added to the existing Non-Facility Associated Signaling (NFAS) with D Channel Backup feature.
ISDN NFAS allows a single D channel to control multiple PRI interfaces. A backup D channel can be configured for use when the primary NFAS D channel fails.
Once the channelized T1controllers are configured for ISDN PRI, only the NFAS primary D channel must be configured; its configuration is distributed to all the members of the associated NFAS group.
Naming Method Lists for AAA Authorization and Accounting
In earlier Cisco IOS releases, only named authentication method lists were supported under Cisco's Authentication, Authorization, and Accounting (AAA) network security services. With Cisco IOS Release 11.3(3)T, AAA has been extended to support both authorization and accounting named method lists. Named method lists for authorization and accounting function the same way as those for authentication; they allow you to define different methods for authorization and accounting and apply those methods on a per interface or per line basis.
MS-CHAP Support
Microsoft Challenge Handshake Authentication Protocol (MS-CHAP) is the Microsoft version of CHAP. Like the standard version of CHAP, MS-CHAP is used for PPP authentication; in this case, authentication occurs between a PC using Microsoft Windows NT or Microsoft Windows 95 and a Cisco router or access server acting as a network access server (NAS).
MS-CHAP differs from the standard CHAP as follows:
•
•
•
•
•
Depending on the security protocols you have implemented, PPP authentication using MS-CHAP can be used with or without Authentication, Authorization and Accounting (AAA) security services. If you have enabled AAA, PPP authentication using MS-CHAP can be used in conjunction with both TACACS+ and RADIUS.
Additional Vendor-Proprietary RADIUS Attributes
Remote Access Dial-In User Server (RADIUS) is an access server authentication, authorization, and accounting protocol originally developed by Livingston, Inc. Although an Internet Engineering Task Force (IETF) draft standard for RADIUS specifies a method for communicating vendor-proprietary information between a network access server and the RADIUS server, some vendors have extended the RADIUS attribute set in a unique way. In this release, Cisco IOS software introduces support for additional vendor-proprietary RADIUS attributes. Users who have implemented security solutions using a vendor-proprietary implementation of RADIUS can now integrate Cisco access routers into their networks more easily.
New Hardware Features in Release 11.3(2)T
The following new hardware features are supported by the Cisco 7000 family of routers in Cisco IOS Release 11.3(2)T. For easy online access, these feature descriptions are linked to the applicable Cisco IOS feature module if one exists. Click on the link to open the feature module.
NPE-200 Network Processing Engine
The NPE-200 for Cisco 7200 series routers is now available. The network processing engine maintains and executes the system management functions for Cisco 7200 series routers. The network processing engine also shares the system memory and environmental monitoring function with the I/O controller. The NPE-200 has an R5000 microprocessor that operates at an internal clock speed of 200 megahertz (MHz), 4 MB of SRAM, and erasable programmable read-only memory (EPROM) for storing sufficient code for booting the Cisco IOS software. For more information on the NPE-200, refer to the publication Network Processing Engine Replacement Instructions.
PA-12E/2FE Ethernet Switch 10BaseT and 100BaseTX Port Adapters
The PA-12E/2FE Ethernet switch 10BASE-T and 100BaseTX port adapters are available on Cisco 7200 series routers. The PA-12E/2FE port adapter provides up to twelve 10-Mbps and two 10/100-Mbps switched Ethernet (10BaseT) and Fast Ethernet (100BaseTX) interfaces for an aggregate bandwidth of 435 Mbps, full-duplex. For more information on the PA-12E/2EF port adapter, refer to the publication PA-12E/2EF 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.
New Software Features in Release 11.3(2)T
The following new software features are supported by the Cisco 7000 family of routers in Cisco IOS Release 11.3(2)T. For easy online access, these feature descriptions are linked to the applicable Cisco IOS feature module if one exists. Click on the link to open the feature module.
Dialer Watch
Dialer Watch is a backup feature that integrates dial backup with routing capabilities. Prior dial backup implementations used the following conditions to trigger backup:
•
•
•
Prior backup implementations may not have supplied optimum performance on some networks, such as those using Frame Relay multipoint subinterfaces or Frame Relay connections that do not support end-to-end VC status updates.
Dialer Watch provides reliable connectivity without relying solely on defining interesting traffic to trigger outgoing calls at the central router. Dialer Watch uses the convergence times and characteristics of dynamic routing protocols. Integrating backup and routing features enables Dialer Watch to monitor every deleted route. By configuring a set of watched routes that define the primary interface, you are able to monitor and track the status of the primary interface as watched routes are added and deleted. Monitoring the watched routes is done in the following sequence:
1
2
3
4
5
6
7
MS Callback
The MS Callback feature provides client-server callback services for Microsoft Windows 95 and Microsoft Windows NT clients. MS Callback supports the Microsoft Callback Control Protocol (MSCB). MSCB is Microsoft's proprietary protocol that is used by Windows 95 and Windows NT clients. MS Callback supports negotiated PPP Link Control Protocol (LCP) extensions initiated and agreed upon by the Microsoft client. MS Callback is added to existing PPP Callback functionality. Therefore, if you configure your Cisco access server to perform PPP Callback using Cisco IOS Release 11.3(2)T or later, MS Callback is automatically available.
MS Callback supports AAA security models using a local database or AAA server.
MSCB uses LCP callback options with suboption type 6. The Cisco MS Callback feature supports clients with a user-specified callback number and server-specified (preconfigured) callback number.
MS Callback does not affect non-Microsoft systems that implement standard PPP LCP extensions as described in RFC 1570. In this scenario, MS Callback is transparent.
PIM Version 2
Protocol-Independent Multicast (PIM) Version 2 includes the following improvements over PIM Version 1:
•
•
•
•
•
•
•
PIM Version 1, together with the Auto-RP feature, can perform the same tasks as the PIM Version 2 bootstrap router. However, Auto-RP is a standalone protocol, separate from PIM Version 1, and is Cisco-proprietary. PIM Version 2 is a standards track protocol in the Internet Engineering Task Force (IETF).
Cisco's PIM Version 2 implementation allows good interoperability and transition between Version 1 and Version 2. You can upgrade to PIM Version 2 incrementally. PIM Versions 1 and 2 can be configured on different routers within one network. Internally, all routers on a shared media network must run the same PIM version. Therefore, if a PIM Version 2 router detects a PIM Version 1 router, the Version 2 router downgrades itself to Version 1 until all Version 1 routers have been shut down or upgraded.
PIM uses the bootstrap router to discover and announce RP-set information for each group prefix to all the routers in a PIM domain. This is the same function accomplished by Auto-RP, but the bootstrap router is part of the PIM Version 2 specification. The bootstrap router mechanism interoperates with Auto-RP.
To avoid a single point of failure, you can configure several candidate bootstrap routers in a PIM domain. A bootstrap router is elected among the candidate bootstrap routers automatically; they use bootstrap messages to discover which bootstrap router has the highest priority. This router then announces to all PIM routers in the PIM domain that it is the bootstrap router.
Routers that are configured as candidate RPs then unicast to the bootstrap router the group range for which they are responsible. The bootstrap router includes this information in its bootstrap messages and disseminates it to all PIM routers in the domain. Based on this information, all routers will be able to map multicast groups to specific RPs. As long as a router is receiving the bootstrap message, it has a current RP map.
Enhanced ATM VC Configuration and Management
The Enhanced ATM Virtual Circuit (VC) Configuration and Management feature set includes new and enhanced capabilities that allow you to create and manage ATM permanent virtual circuits (PVCs) and switched virtual circuits (SVCs) with more ease and improved integrity. This feature set includes the following five subfeatures:
•
The New VC Configuration subfeature allows you to create ATM PVCs, SVCs, static maps, and associated VC parameters more easily and with fewer errors using new ATM commands in new VC command modes.
•
The VC Integrity Management subfeature allows you to manage your ATM PVCs and SVCs so that your router receives immediate notification when these VCs go down in your network. Upon notification, protocols can reroute packets and prevent unpredictable and relatively long timeout periods.
•
The PVC Discovery subfeature allows you to make your router automatically assign (or discover) PVCs on an ATM interface or subinterface using information from an attached adjacent switch.
•
The Multiprotocol Inverse ARP subfeature allows you to enable dynamic protocol mapping between an ATM PVC and a network address by configuring Inverse Address Resolution Protocol (Inverse ARP) on ATM PVCs running IP or IPX.
•
The Rate Queue Tolerance subfeature allows you to configure a range of peak rates on a single rate queue, thereby improving ATM rate queue usage.
Cisco Database Connection
The Cisco Database Connection feature enables Cisco routers to implement IBM's Distributed Relational Database Architecture (DRDA) level 3 over TCP/IP. The Cisco router with Database Connection exists in the TCP/IP network, and clients use the Database Connection IP address and port on the router to connect to the IBM host system that exists in the SNA network.
When Database Connection is configured on a router, client-based Open Database Connectivity (ODBC) applications can connect to IBM's family of IBM D2 relational databases, which include:
•
•
•
•
•
The router with Database Connection converts DRDA packets over TCP/IP to DRDA packets over Advanced Program-to-Program Communication (APPC) (LU 6.2) and then routes them to DB2 databases. Database Connection runs as a TCP/IP daemon on the router, accepting DRDA client connections over TCP/IP. When a client connects to the database on an IBM mainframe host, Database Connection allocates an APPC conversation over SNA to an IBM server, and acts as a gateway between DRDA over TCP/IP and DRDA over APPC.
DRP Server Agent Enhancements
The Director Response Protocol (DRP) Server Agent enhancements are as follows:
•
•
New Software Features in Release 11.3(1)T
The following new software features are supported by the Cisco 7000 family of routers in Cisco IOS Release 11.3(1)T. For easy online access, these feature descriptions are linked to the applicable Cisco IOS feature module if one exists. Click on the link to open the feature module.
SNMP Manager
The SNMP Manager feature allows a router to serve as an SNMP manager. As an SNMP manager, the router can send SNMP requests to agents and receive SNMP responses and notifications from agents. When the SNMP manager process is enabled, the router can query other SNMP agents and process incoming SNMP traps.
SNMP Inform Requests
The SNMP Inform Requests feature allows routers to send inform requests to SNMP managers. Routers can send notifications to SNMP managers when particular events occur. For example, an agent router might send a message to a manager when the agent router experiences an error condition.
SNMP notifications can be sent as traps or inform requests. Traps are unreliable because the receiver does not send any acknowledgment when it receives a trap. The sender cannot determine if the trap was received. However, an SNMP manager that receives an inform request acknowledges the message with an SNMP response protocol data unit (PDU). If the manager does not receive an inform request, it does not send a response. If the sender never receives a response, the inform request can be sent again. Thus, informs are more likely to reach their intended destination.
Because they are more reliable than traps, informs consume more resources in the router and in the network. Unlike a trap, which is discarded as soon as it is sent, an inform request must be held in memory until a response is received or the request times out. Also, traps are sent only once, whereas an inform request may be retried several times. The retries increase traffic and contribute to a higher overhead on the network. Thus, traps and inform requests provide a trade-off between reliability and resources. If it is important that the SNMP manager receive every notification, use inform requests. On the other hand, if you are concerned about traffic on your network or memory in the router and you do not need to receive every notification, use traps.
x Digital Subscriber Line Bridge Support
The x Digital Subscriber Line Bridge Support feature enables you to configure a router for intelligent bridge flooding for x digital subscriber line and other bridge applications.
Limitations and Restrictions
This section contains important information about limitations and restrictions of Cisco IOS Release 11.3 T software. The following information describes the changes in release number for Release 11.3 T.
Release 11.3(3a)T Fixes Caveats CSCdk01707 and CSCdk08772
The Cisco 7500 series RSP2 and RSP4 products in Cisco IOS Release 11.3(3)T were deferred because of a severe 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 Release 11.3(3a)T.
The defect is CSCdk01707 and is described as follows:
•
Software releases affected: This caveat affects all systems configured with dual Route Switch Processors (RSPs) (HSA feature). All "v" images for the following Cisco IOS Releases have been deferred: 11.1(18.1)CA through 11.1(18.2)CA, 11.1(16.3)CC through 11.1(17.4)CC, 11.1(17)CT, 11.2(12.3)P through 11.2(13.4)P, 11.3(1) through 11.3(3), and 11.3(1)T through 11.3(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: 11.1(18)CA, 11.1(18)CC, 11.1(18)CT, 11.2(14)P, 11.3(3a), or 11.3(3a)T.
[CSCdk01707]
CSCdk08772 is a duplicate of CSCdk01707 and is described as follows:
•
CSCdk01707 was introduced by the fix for CSCdj36366, which is described as follows:
•
Release 11.3(3a)T and all subsequent releases of Cisco IOS Release 11.3 T software include the fix for this caveat.
Release 11.3(2a)T Fixes Caveat CSCdj52309
The Cisco 7500 series products in Cisco IOS software release 11.3(2)T 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 Release 11.3(2a)T.
The defect is CSCdj52309 and is described as follows:
•
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 bridging (TLB), source-route bridging (SRB), and remote source-route bridging (RSRB).
When the packet tunneling logic on RSP- or Route Switch Module (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, and 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), or 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 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.
Note
•
CSCdj33812 incorporated a configurable command that is 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.
Router(config)#memory cache-policy io uncached
Router(config)#endRouter# show rsp
Throttle count 0, DCL timer count 0
active 0, configured 1
netint usec 4000, netint mask usec 200
DCL spurious 0Caching Strategies:
Processor private memory: write-back
Kernel memory view: uncached
IO (packet) memory: uncached
Buffer header memory: uncachedTo restore the MEMD caching policy to the original write-through policy, issue the memory cache-policy io write-through command.
Router# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#memory cache-policy io write-through
Router(config)#end
Router#show rsp
Throttle count 0, DCL timer count 0
active 0, configured 1
netint usec 4000, netint mask usec 200
DCL spurious 0
Caching Strategies:
Processor private memory: write-back
Kernel memory view: write-back
IO (packet) memory: write-through
Buffer header memory: uncached•
If operating with images that do not have the CSCdj33812 support, use the test rsp cache memd-fastswitch uncache command.
You need to enter the above command after every router 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 10.3, 11.0, and 11.1 releases; however, no special images are being created because the anomalous behaviors are not present in those releases.
[CSCdj52309]
Release 11.3(2a)T and all subsequent releases of Cisco IOS software include the fix for this caveat.
New TACACS+ Attribute-Value Pair
A new authorization feature was added in Release 11.3(1) that allows for separate configuration and authorization of Multilink PPP. This can cause Multilink PPP authorization to fail in Terminal Access Controller Access Control System Plus (TACACS+) servers that do not include the relevant authorization permissions in the configuration. For TACACS+, the following attribute-value (AV) pair should be added for all users who are allowed to negotiate Multilink PPP:
service = ppp protocol = multilink {Removed bridge group multicast-source Command
As of Release 11.3(2)T, the bridge group multicast-source command is no longer available. This command was removed to comply with the source-route transparent (SRT) bridging implementation.
Encryption Feature Sets
Encryption feature sets (for example IP 40 and IP 56) are not available in Cisco IOS Releases 11.3(1)T and 11.3(2)T. These feature sets are available in Release 11.3(3)T and later 11.3 T releases.
