The following sample show version command output is from a router running a Cisco 7200 series software image with Release 12.0(7)XE2:
router>show versionCisco Internetwork Operating System SoftwareIOS (tm) 7200 Software (C7200-JS-MZ), Version 12.0(7)XE2, RELEASE SOFTWAREUpgrading to a New Software Release
For information about upgrading to a new software release, see the product bulletin Cisco IOS Software Release 12.0 Upgrade Paths and Packaging Simplification located at:
http://www.cisco.com/kobayashi/library/12.0/120MigrPaths.pdf
If you do not have an account on CCO and want general information about upgrading to a new software release, see the product bulletin Cisco IOS Software Release 11.3 Upgrade Paths and Packaging Simplification (#703: 12/97) on CCO at:
Service & Support: Software Center: Cisco IOS Software: Product Bulletins
Under Cisco IOS 11.3, click Cisco IOS Software Release 11.3 Upgrade Paths (#703: 12/97).
This product bulletin does not contain information specific to Cisco IOS Release 12.0 but provides generic upgrade information that may apply to Cisco IOS Release 12.0.
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.
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.
Release 12.0(5)XE is based on Cisco IOS Release 12.0(5)T. All functionality in Cisco IOS Release 12.0(5)T is also in Release 12.0(5)XE, and, subsequently, Cisco IOS Release 12.0(7)XE2.
Releases 12.0(5)XE through 12.0(7)XE2 support the same feature sets as Release 12.0(5)T, but Releases 12.0(5)XE through 12.0(7)XE2 can include new features supported by the Cisco 7000 family of routers.
CautionCisco IOS images with strong encryption (including, but not limited to 168-bit [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 may require an export license. Customer orders may be denied or subject to delay due to United States government regulations. When applicable, the purchaser or the user must obtain local import and use authorizations for all encryption strengths. Contact your sales representative or distributor for more information, or send an e-mail to export@cisco.com.

The dual-width OC-12c Dynamic Packet Transport (DPT) port adapter is available on Cisco 7200 series routers and Cisco 7200 VXR series routers. The DPT is an OC-12c interface used in Cisco 7200 series and Cisco 7200 VXR routers to provide a shared IP over SONET capability.
The OC-12c Dynamic Packet Transport (DPT) Interface Processor (DPTIP) is available on Cisco 7500 series routers. The DPT is an OC-12c interface that uses second-generation Versatile Interface Processor (VIP2) technology to provide a shared IP-over-SONET capability and it complies with IEEE 802.3 specifications. The DPTIP assembly consists of a VIP2 with a dual-width DPT port adapter permanently attached to it.
Inverse Multiplexing over ATM on Cisco 7100 series routers
The PA-A3-8T1IMA and PA-A3-8E1IMA port adapters are now available for Cisco 7100 series routers.
PA-MC-2T3+ Port Adapter
The PA-MC-2T3+ has been added to the 12.0XE train in Release 12.0(7)XE1.
Two-Port Multichannel DS1/PRI and Multichannel E1/PRI port adapters:
Two-port versions of the Multichannel DS1/PRI and Multichannel E1/PRI port adapters are now available for Cisco IOS Release 12.0(7)T.
Gigabit Ethernet (PA-GE Support)
The PA-GE is a single-port port adapter that, when combined with the appropriate fiber-optic cable and a Gigabit Interface Converter (GBIC), provides one Gigabit Ethernet (GE) interface that is compliant with the IEEE.
802.3z specification. The GE interface on a PA-GE operates in full-duplex mode. The PA-GE is supported by the Cisco 7200 VXR routers. Please note that this port adapter is not currently supported by the fourth-generation Versatile Interface Processor (VIP4). See the following document for further information:
http://www.cisco.com/univercd/cc/td/doc/product/core/7200vx/72vxpa/7188page/index.htm
New Software Features in Release 12.0(7)XE1
The following new hardware features are supported by the Cisco 7000 family of routers for Release 12.0(7)XE1.
dWFQ for RSVP
In earlier software releases, Resource Reservation Protocol (RSVP) on Cisco 7500 series routers would leverage RSP-based weighted fair-queuing to guarantee bandwidth to RSVP flows. In Release 12.0(7)XE1, RSVP now interoperates with distributed weighted fair-queuing (dWFQ), thus offloading the RSP of the overhead of the queueing function and improving RSVP scalability. RSVP support of dWFQ is transparent to the user.
RSVP-based Voice over IP (VoIP) will be available in a future software release.
Cisco IOS Firewall Feature Set for Cisco 7500 Series Routers
The Cisco IOS Firewall feature set, available for a wide range of Cisco router platforms, adds more depth and flexibility to existing Cisco IOS software security capabilities, enriching features such as authentication, encryption, and failover with robust firewall functionality and intrusion detection. A Cisco IOS software-based, integrated firewall solution scales to meet the bandwidth and performance requirements of any network. It also maximizes a Cisco router investment by combining multiprotocol routing functionality with sophisticated security policy enforcement throughout the network.
The Cisco IOS Firewall feature set delivers cost-effective perimeter security packaged with advanced features like stateful, application-based filtering, dynamic per-user authentication and authorization, defense against network attacks, Java blocking, and real-time alerts. Because it is completely interoperable with Cisco IOS software features including NAT, VPN tunneling protocols, Cisco Express Forwarding (CEF), AAA extensions, Cisco encryption technology, and Cisco IOS IPSec, it is a complete, integrated VPN solution.
Fast EtherChannel Enhancements for Cisco 7200 Routers
Fast EtherChannel provides higher bidirectional bandwidth, redundancy, and load sharing. Up to four Fast Ethernet interfaces can be bundled in a port-channel, and the router or switch can support up to four port-channels. The Fast EtherChannel feature is capable of load balancing traffic across the Fast Ethernet links. Unicast, broadcast, and multicast traffic is distributed across the links providing higher performance and redundant parallel paths. In the event of a link failure, traffic is redirected to remaining links within the Fast EtherChannel without user intervention.
In this release of the Fast EtherChannel feature, IP traffic is distributed over the port-channel interface while traffic from other routing protocols is sent over a single link. Bridged traffic is distributed based on the Layer 3 information in the packet. If the Layer 3 information does not exist in the packet, the traffic is sent over the first link.
Fast EtherChannel supports all features currently supported on the Fast Ethernet interface. You must configure these features on the port-channel interface rather than on the individual Fast Ethernet interfaces. Fast EtherChannel connections are fully compatible with Cisco IOS virtual LAN (VLAN) and routing technologies. The Inter-Switch Link (ISL) VLAN trunking protocol can carry multiple VLANs across a Fast EtherChannel, and routers attached to Fast EtherChannel links can provide full multiprotocol routing with support for host standby using Host Standby Router Protocol (HSRP).
The port-channel (consisting of up to four Fast Ethernet interfaces) is treated as a single interface. The port-channel interfaces is used in the Cisco IOS software to maintain compatibility with existing commands on the Catalyst 5000 switch. You create the Fast EtherChannel by using the interface port-channel interface configuration command. You can assign up to four Fast Ethernet interfaces to a port-channel by using the channel-group interface configuration command.
Inverse Multiplexing over ATM Enhancements
The PA-A3-IMA port adapter has added the following functionalities:
•
•
•
Low Latency Queueing for the Versatile Interface Processor Enhancement
The tx-ring-limit command has been added as am option on the 12.0XE train. This command allows users to limit the number of particles on a transmission ring for the PA-A3 port adapter. For additional information on this command, see the Low Latency Queuing feature module.
PA-MC-T3 Multi-Channel T3 Synchronous Serial Port Adapter Enhancement
The addition of the equipment {customer | network} loopback command enables you to configure the PA-T3-MC as network equipment or customer equipment so it can operate based on the ANSI T1.403 standard. When a PA-MC-T3 is configured as Customer Equipment, all loopback requests are honored. When configured as network equipment the PA-MC-T3 ignores the following DS-3 and DS-1 loopback requests:
•
•
•
•
•
•
•
When configured as network equipment, the PA-MC-T3 recognizes router network loop commands as line loopback commands.
Simple Network Management Protocol (SNMP) requests for loopbacks are always honored, whether the PA-MC-T3 is configured as customer equipment or network equipment.
MPLS Class of Service Classification using MPLS Experimental Bits
The MPLS experimental bits can now be used as classification criteria within a QoS policy on the VIP platform. Using the Modular QoS CLI, a class map can be defined wherein one of the available match criteria is the MPLS experimental bits. A policy map can then be defined to enable VIP-based CBWFQ or Low Latency Queueing for the MPLS class.

New Hardware Features in Release 12.0(5)XE5
The following new hardware features are supported by the Cisco 7000 family of routers for Release 12.0(5)XE5.
Integrated Service Module
The Integrated Service Module (ISM) is a Layer 3 encryption service module that supports IP Security Protocol (IPSec) protection of IP datagrams on Cisco 7100 series routers. The ISM provides hardware-based encryption, thus freeing resources on the network processor [NP].
The ISM provides hardware-accelerated support for the following encryption functions:
•
•
•
•
•
For Release 12.0(5)XE5, ISM has the following restrictions:

New Software Features in Release 12.0(5)XE5
The following new software features are supported by the Cisco 7000 family of routers for Release 12.0(5)XE5.
PPTP with MPPE
Enterprises are increasingly looking to the Internet as a means of enabling new, lower-cost services for their users. The ubiquity of the Internet makes it very easy for remote and mobile users to connect anywhere on the planet, all that's required is an ISP to provide Internet access. At the same time, Enterprises are hesitant to trust the Internet as a transport for private company data and are looking for means to use the Internet in a secure way.
Point-to-Point Tunneling Protocol with Microsoft's Point-to-Point Encryption (PPTP/MPPE) provides a solution to this need. The PPTP protocol (Point-to-Point Tunneling Protocol) provides a mechanism to tunnel user's data across the Internet to the edge of the enterprise network, so that users can use any ISP account and any Internet-routable IP address to access the edge of the enterprise network. At the edge, the IP packet is detunneled and the enterprise IP address space is used for traversing the internal network. MPPE (Microsoft Point to Point Encryption) protocol provides an encryption service that protects the datastream as it traverses the Internet. MPPE is available in 2 forms: 40-bit encryption, which is widely available throughout the world, and 128-bit encryption which may be subject to certain export controls when used outside the United States.
Service providers also have an opportunity to leverage PPTP/MPPE when deploying managed services for enterprise customers. In this model, the Service Provider deploys and manages the enterprise's PPTP/MPPE tunnel server or PNS (PPTP Network Server) and manages this service on behalf of the enterprise. The tunnel server may be hosted at the Service Providers POP, or may be located at the enterprise edge, but managed by the Service Provider.
Using Cisco IOS Technology, PPTP/MPPE PNS service may be provided by the Cisco 7100 and 7200 platforms.
Low Latency Queueing for the VIP
The Low Latency Queueing for the Versatile Interface Processor (VIP) feature brings priority queueing to Class-Based Weighted Fair Queueing (CBWFQ). Priority queueing allows delay-sensitive data such as voice to be dequeued and sent first (before packets in other queues are dequeued), giving delay-sensitive data preferential treatment over other traffic.
Without Low Latency Queueing, CBWFQ provides weighted fair queueing based on defined classes with no priority queue available for real-time traffic. CBWFQ allows you to define traffic classes and then assign characteristics to that class. For example, you can designate the minimum bandwidth delivered to the class during congestion.
For CBWFQ, the weight for a packet belonging to a specific class is derived from the bandwidth you assigned to the class when you configured it. Therefore, the bandwidth assigned to the packets of a class determines the order in which packets are sent. All packets are serviced fairly based on weight; no class of packets may be granted priority. This approach can pose problems for voice traffic on low bandwidth links that are largely intolerant of delay, especially variation in delay. For voice traffic, variations in delay might introduce irregularities of transmission manifesting as jitter in the heard conversation.
The Low Latency Queueing feature provides priority queueing for CBWFQ, reducing jitter in voice conversations. Configured by the priority command, Low Latency Queueing enables use of a single priority queue within CBWFQ at the class level, allowing you to direct traffic belonging to a class to the CBWFQ priority queue. To enqueue class traffic to the priority queue, you configure the priority command for the class after you specify the named class within a policy map. (Classes to which the priority command is applied are considered priority classes.) Within a policy map, you can give one or more classes priority status. When multiple classes within a single policy map are configured as priority classes, all traffic from these classes is enqueued to the same, single, priority queue.

New Software Features in Release 12.0(5)XE3
The following new software features are supported by the Cisco 7000 family of routers for Release 12.0(5)XE3.
Quality of Service for Virtual Private Networks
When packets are encapsulated by tunnel or encryption headers, Quality of Service (QoS) features are unable to examine the original packet headers and correctly classify the packets. Packets traveling across the same tunnel have the same tunnel headers, so the packets are treated identically if the physical interface is congested.
With the growing popularity of Virtual Private Networks (VPNs), the need to classify traffic within a traffic tunnel is gaining importance. QoS features have historically been unable to classify traffic within a tunnel. With the introduction of the Quality of Service for Virtual Private Networks (QoS for VPNs) feature, packets can now be classified before tunneling and encryption occur. The process of classifying features before tunneling and encryption is called preclassification.
The QoS for VPNs feature is designed for tunnel interfaces. When the new feature is enabled, the QoS features on the output interface classify packets before encryption, allowing traffic flows to be adjusted in congested environments. The end result is more effective packet tunneling.
New Hardware Features in Release 12.0(5)XE2
The following new hardware features are supported by the Cisco 7000 family of routers for Release 12.0(5)XE2.
E1 Support for Two-Port T1/E1 High-Capacity Digital Voice Port Adapter for Cisco 7200 Series Routers
E1 applications, which were unavailable for the two-port T1/E1 high-capacity digital voice port adapter for Cisco 7200 series routers on Cisco IOS Release 12.0(5)XE, have been enabled for Cisco IOS Release 12.0(5)XE2.
For additional information on the two-port T1/E1 high-capacity digital voice port adapter for Cisco 7200 series routers, see the Two-Port T1/E1 High-Capacity Digital Voice Port Adapter for Cisco 7200 Series Routers installation and configuration note.
New Software Features in Release 12.0(5)XE2
The following new software feature is supported by the Cisco 7000 family of routers for Release 12.0(5)XE2.
Network-Based Application Recognition (NBAR)
As IP Quality of Service (QoS) technology matures and customers begin QoS deployment in production networks, new requirements for packet classification have emerged. Today's applications require high performance to ensure competitiveness in an increasingly fast-paced business environment. Networks provide a variety of services to ensure that mission-critical applications receive the required bandwidth for high performance. Today's Internet-based client-server applications make it difficult for networks to identify and provide the proper level of control.
The Network-Based Application Recognition (NBAR) engine solves this problem by adding intelligent network classification to network infrastructures. NBAR is a new classification engine that recognizes a wide variety of applications, including web-based and other difficult-to-classify protocols that utilize dynamic port assignments. When an application is recognized by NBAR, a network can invoke services for that specific application. NBAR ensures that network bandwidth is used efficiently by working with Quality of Service features such as:
•
•
•
•
NBAR introduces several new classification features:
•
•
•
•
NBAR provides classification of static port traffic for easier configurations. Access lists also provide the same classification ability for static port protocols.
NBAR provides a special Protocol Discovery feature that determines which application protocols are traversing a network at any given time. The Protocol Discovery feature captures key statistics associated with each protocol in a network. These statistics can be used to define traffic classes and QoS policies for each traffic class.
New Hardware Features in Release 12.0(5)XE
The following new hardware features are supported by the Cisco 7000 family of routers for Release 12.0(5)XE.
Two-Port T1/E1 High-Capacity Digital Voice Port Adapter for Cisco 7200 Series Routers
The T1/E1 VXC port adapter (PA-VXC-2TE1) is a multichannel packet voice port adapter that allows a Cisco 7200 series or Cisco 7200 VXR router to become a dedicated packet voice hub or packet voice gateway that connects to both private branch exchanges (PBXs) and the Public Switched Telephone Network (PSTN). These connections allow packet voice and fax calls to be placed over the WAN and sent through the gateway into the traditional circuit-switched voice infrastructure.
Note
In Voice over IP, the digital signal processor (DSP) segments the voice signal into frames, which are then coupled in groups of two and stored in voice packets. These voice packets are transported using IP in compliance with ITU-T specification H.323. Because Voice over IP is a delay-sensitive application, a well-engineered end-to-end network is required to use it successfully. Fine-tuning your network to adequately support Voice over IP involves a series of protocols and features geared toward quality of service (QoS). Traffic shaping considerations must be taken into account to ensure the reliability of the voice connection.
Inverse Multiplexing over ATM Port Adapter
The Inverse Multiplexing over ATM (IMA) port adapter is a single-width port adapter that allows Cisco 7200 series and Cisco 7500 series routers to support inverse multiplexing over ATM. The port adapter allows WAN uplinks at speeds ranging from 1.544 Mbps to 12.288 Mbps for T1 or E1 environments.
Cisco's scalable ATM IMA solution means that network designers and managers can deploy only the bandwidth they need, using multiple T1 or E1 connections instead of more expensive T3 or OC-3 lines to bridge between LANs and ATM WAN applications. Enterprises and branch offices can aggregate traffic from multiple lower-bandwidth physical transmission media, such as T1 or E1 pipes, to transmit voice and data at high-bandwidth connection speeds.
New Software Features in Release 12.0(5)XE
The following new software feature is supported by the Cisco 7000 family of routers for Release 12.0(5)XE.
Distributed Traffic Shaping
Many enterprise and service provider customers need to shape traffic in their networks and sometimes need to shape IP traffic independently of the underlying interface. In other cases, the goal is to perform traffic shaping to ensure adherence to committed information rates on Frame Relay links.
The distributed Traffic Shaping (dTS) feature is one element used to manage the bandwidth of an interface to avoid congestion, meet remote site requirements, and conform to a service rate that is provided on that interface.
The distributed Traffic Shaping (dTS) feature uses queues to buffer traffic surges that can congest a network. Data is buffered and then sent into the network at a regulated rate. This ensures that traffic will behave in accordance with the configured descriptor, as defined by CIR (mean rate), Bc (burst size), and Be (excess burst size). With the defined average bit rate and burst size that are acceptable on that shaped entity, you can derive a time interval value.
The excess burst size (Be) allows more than the burst size (Bc) to be sent during a time interval under certain conditions. Therefore, dTS provides two types of shape commands: average and peak. When shape average is configured, the interface sends no more than the burst size (Bc) for each interval, achieving an average rate no higher than the mean rate (CIR). When shape peak is configured, the interface sends Bc plus Be bits in each interval.
In a link layer network such as Frame Relay, the network sends messages with the forward explicit congestion notification (FECN) or backward explicit congestion notification (BECN) if there is congestion. With the dTS feature, the traffic shaping adaptive mode takes advantage of these signals and adjusts the traffic descriptors. This approximates the rate to the available bandwidth along the path.
Important Notes
The following sections contain important notes that apply to the Cisco 7000 family of routers.
Image Deferral, Cisco 7200 Boot Images
Cisco IOS Release 12.0(5)XE, Cisco IOS Release 12.0(7)XE and Cisco IOS Release 12.0(7)XE1 bootimages for Cisco 7200 series routers have been deferred due to the following caveat:
CSCdm85656—Reduce size of boothelper image c7200-boot-mz
Cisco IOS Release 12.0(5)XE, Cisco IOS Release 12.0(7)XE and Cisco IOS Release 12.0(7)XE1 for the 7200 bootimages (c7200-boot-mz-*) have outgrown the FLASH SIMM used to store the bootimage on the Input/Output Controllers used in the Cisco 7200 series routers. Although the present released images are below 4MB, the available space after formatting the 4MB FLASH SIMM is 3.25MB. Cisco utilizes the FLASH SIMM to not only store the bootimage but also to store crashinfo files. After providing 300KB for up to two crashinfo files, only 2.96MB is available for the bootimage. Using an oversized bootimage would not allow space for crashinfo files into the FLASH SIMM. In some cases, the bootimage itself may not fit in the FLASH SIMM.

Basic System Services
•
In certain configurations, a Cisco 7120 router with an Integrated Service Module (ISM) might receive the following error message:
00:42:22: isa_rx_error: B208, id 59, pool offset 000:42:25: IP: s=204.64.105.25 (local), d=4.4.140.98 (FastEthernet0/0), len 112, encapsulation failed, proto=50This error message seems to indicate that packets are getting encrypted and decrypted based on the IPSec SA counters, but the router isn't placing these packets onto the interface.
There are no known workarounds.
Interfaces and Bridging
•
If a configuration change is applied to an ATM subinterface before shuting down the subinterface, the main ATM interface goes to a down/down state. A reload is required to restore the interface to it's normal state.
Workaround: Shutdown the subinterface before applying changes.
•
In Cisco 7100 and 7200 series routers, transparent bridging using the PA-DTR Token Ring Port Adapter does not operate properly. The show bridge command fails to indicate any of the end-stations in the bridge table.
Workaround: On the Cisco 7200 series routers, use alternative token ring port adapters. There are no known workarounds for the Cisco 7100 series routers.
Miscellaneous
•
The following problem occurs on serial interfaces after the default value of the clock-rate or bandwidth has been changed.
When Class Based Weighted Fair Queuing (CBWFQ) for the Versatile Interface Processor is enabled on the interface, the CBWFQ weights are chosed based on the default bandwidth, not the modified bandwidth, of the interface.
There are no known workarounds.
•
Fast-switching on an ATM IMA interface might cause RTP packets from a Cisco 7200 series router to be dropped. Although the call is placed, the audio stream from the 7200 is dropped off the interface. The result is a one-way audio path.
Please note that this problem does not appear to affect calls switched thru a Cisco 7200 series router, only calls generated by a Cisco 7200 series router.
Workaround: Disable fast-switching.
•
When using EIGRP and two ipsec tunnels, only one ipsec tunnel pings successfully, the other ipsec tunnel fails to ping.
Workaround: Use the crypto map local-address command to create a single address as the identity of the router by using one local-address for both crypto maps.
•
The write memory command sometimes fails and produces the following error message:
private-config file open failedWorkaround: Use the write erase command before using the write memory command.
•
In certain configurations, a Cisco 7100 series router with ATM interfaces might experience a software forced reload. This reload indicate that the pak_pool_maximum_size is responsible for the reload.
There are currently no known workarounds.
•
Keepalives are not supported on ISM if more than 200 tunnels are created.
Workaround: If you need to create more than 200 tunnels, turn off keepalives.
•
When two Inverse Multiplexing port adapters attempt to connect to one another in certain configurations, one of the Versatile Interface Processors (VIPs) on one of the Inverse Multiplexing over ATM (IMA) port adapters might not be recognized.
There is no known workaround.
•
In certain configurations, a Cisco 7200 series router running the IP software image (c7200-is-mz) might cause the software to experience memory corruption.
There is no known workaround.
•
As the number of IPSec sessions increases on an ISA port adapter, the impact of checking an extended access control list (ACL) might cause the throughput (NDR or no_drop_rate) rate to decrease.
There is no known workaround.
•
In certain environments, Cisco 7140 router continuously exchanging heavy traffic loads might unexpectedly reload. There is no known workaround.
•
On RSP8 platforms, an Extended On-line Insertion and Removal (EOIR) attempt might fail if a VIP receives a bus error while accessing MEMD above the 2 MB boundary due to a CyBus stall, which is a normal portion of the installation.
There is no known workaround.
•
While attaching service-policies to atm-lite sub-interfaces, a Versatile Interface Processor (VIP) reloads while attaching a policy map configured with traffic shaping or bandwidth to an interface.
Workaround: Avoid attaching service-policies to atm-lite subinterfaces when using a VIP.
•
A GEIP running Cisco IOS Release 12.0(5)XE1 with local switching might drop a large number of packets.
There is no known workaround.
•
This problem occurs with a Versatile Interface Processor (VIP) with 32MB of DRAM. When using Quality of Service (QoS) features on all interfaces of a channelized T3 port adapter, the VIP might reload while configuring certain features.
Workaround: Upgrade the VIP to 64mb of DRAM for this environment.
•
A Cisco 7100 VPN series router running the IP/FW IPSec 56 image on Cisco IOS Release 12.0(5)XE rejects commands for authentication proxy on the command line interface (CLI).
There is no known workaround.
•
A Cisco 7500 series router running a Cisco IOS Release 12.0(5) crypto image is unable to ping another router.
There is no known workaround.
•
A Cisco 7500 series router running a Cisco IOS Release 12.0(5) crypto image fails to display an EIGRP routing table to other routers.
There is no known workaround.
•
When online insertion and removal (OIR) is used to access the Sandisk, the dir disk command might pause the Route Switch Processor (RSP).
There is no known workaround.
•
A Cisco 7100 series router running the Enterprise/FW IPSec 56 (c7100-jos56I-mz) software image might experience spurious access errors.
There is no known workaround.
•
When Cisco Express Forwarding (CEF) is configured for a packet size larger than 1948, the ping command might be unsuccessful.
There is no known workaround.
•
On Cisco 7500 series routers, the copying startup-configuration command has difficulties working consistently with configurations larger than 13396 bytes.There is no known workaround.
•
When two Cisco 7500 series routers with connections to Internet Service Providers (ISPs) are connected, the Cisco 7500 series routers might have trouble pinging each other.
Workaround: Reload the router.
•
A Cisco 7200 series router supporting the NPE-300 might reload during IPX routing.
There are no known workarounds.
•
A Cisco 7200 series router running pagent traffic on a CT3 port adapter might reload.
There are no known workarounds.
•
An RSP 8 (Route Switch Processor 8) with 64 MB of memory might utilize too much memory and subsequently fail to receive output from a dir disk1 output command.
•
A Cisco 7200 series router configured with the IMA port adapter might run slowly after configuring a large number of subinterfaces and virtual circuits.
There is no known workaround.
NBAR
•
If the router has a configured class map or an interface has an attached service policy when loading a new Packet Description Language Module (PDLM) from flash memory, NBAR configuration information could be lost.
Workaround: When loading a PDLM from Flash memory, remember to detach service policies and remove class map configurations.
•
The byte counts from the show ip nbar protocol-discovery command output might differ from the byte count statistics from the show interface stat command. This mismatch occurs when the packet counts match.
There is no known workaround.
•
The ip nbar port-map ? command displays incorrect options when non-UDP/TCP protocols are running. The incorrect options indicate that certain UDP/TCP applications are allowed with the IP NBAR port map. These indications are incorrect.
•
The ip nbar port-map command does not allow 15 additional port numbers. The other 16 port numbers that are available with the router are unaffected.
•
Attaching service policies to tunnel interfaces is not currently supported in Release 12.0(5)XE2. Attempting to attach a service-policy to a tunnel interface will not generate an error message.
•
Disabling Cisco Express Forwarding (CEF) switching after applying and attempting to disable a service policy might produce an error message indicating that CEF switching needs to be enabled. This message is unimportant because the service policy has already been removed.
