Feature Set Tables

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

Cisco IOS Release 12.2(9)YE supports the same feature sets as Cisco IOS Release 12.2, but Cisco IOS Release 12.2(9)YE can include new features supported by the Cisco 7000 family.


Caution Cisco IOS images with strong encryption (including, but not limited to, 168-bit Triple Data Encryption Standard [3DES] data encryption feature sets) are subject to United States government export controls and have limited distribution. Strong encryption images to be installed outside the United States are likely to require an export license. Customer orders may be denied or subject to delay because of United States government regulations. When applicable, purchaser and user must obtain local import and use authorizations for all encryption strengths. Please contact your sales representative or distributor for more information, or send an e-mail to export@cisco.com.

Table 2 lists the features and feature sets supported by the Cisco 7401 ASR routers in Cisco IOS Release 12.2(9)YE and uses the following conventions:

There are no new hardware features supported by the Cisco 7000 family for Cisco IOS Release 12.2(9)YE.

New Software Features in Cisco IOS Release 12.2(9)YE

The following new software features are supported by the Cisco 7000 family for Cisco IOS Release 12.2(9)YE:

IPSec VPN High Availability Enhancements

Platforms: Cisco 7401 ASR routers

The IPSec VPN High Availability feature consists of two new features—Reverse Route Injection and Hot Standby Router Protocol and IPSec—that work together to provide users with a simplified network design for VPNs and reduced configuration complexity on remote peers with respect to defining gateway lists.

Reverse Route Injection

Reverse Route Injection (RRI) is a feature designed to simplify network design for Virtual Private Network (VPNs) in which there is a requirement for redundancy or load balancing. RRI works with both dynamic and static crypto maps.

In the dynamic case, as remote peers establish IPSec security associations (SAs) with an RRI-enabled router, a static route is created for each subnet or host protected by that remote peer. For static crypto maps, a static route is created for each destination of an extended access-list rule.

When routes are created, they are injected into any dynamic routing protocol and distributed to surrounding devices. This traffic flows, requiring IPSec to be directed to the appropriate RRI router for transport across the correct SAs to avoid IPSec policy mismatches and possible packet loss.

Hot Standby Router Protocol and IPSec

Hot Standby Router Protocol (HSRP) is designed to provide high network availability by routing IP traffic from hosts on Ethernet networks without relying on the availability of any single router. HSRP is particularly useful for hosts that do not support a router discovery protocol, such as ICMP Router Discovery Protocol (IRDP), and do not have the functionality to switch to a new router when their selected router reloads or loses power. Without this functionality, a router that loses its default gateway because of a router failure is unable to communicate with the network.

HSRP is configurable on LAN interfaces using standby command line interface (CLI) commands. It is now possible to use the standby IP address from an interface as the local IPSec identity, or local tunnel endpoint.

By using the standby IP address as the tunnel endpoint, failover can be applied to VPN routers by using HSRP. Remote VPN gateways connect to the local VPN router via the standby address that belongs to the active device in the HSRP group. In the event of failover, the standby device takes over ownership of the standby IP address and begins to service remote VPN gateways.

VDM 1.1.1

Platforms: Cisco 7401 ASR routers

VPN Device Manager (VDM) release 1.1.1 supports 7400 series routers. For more information about VDM, see Installation and Release Notes for VPN Device Manager1.1.1.

VPN Acceleration Module

Platforms: Cisco 7401 ASR routers

The VPN Acceleration Module (VAM) is a single-width acceleration module. It provides high-performance, hardware-assisted tunneling and encryption services suitable for virtual private network (VPN) remote access, site-to-site intranet, and extranet applications. It also provides platform scalability and security while working with all services necessary for successful VPN deployments — security, quality of service (QoS), firewall and intrusion detection, service-level validation, and management. The VAM off-loads IPSec processing from the main processor, thus freeing resources on the processor engines for other tasks.

The VAM provides hardware-accelerated support for the following multiple encryption functions:

56-bit Data Encryption Standard (DES) standard mode: Cipher Block Chaining (CBC)

3-Key Triple DES (168-bit)

Secure Hash Algorithm (SHA)-1 and Message Digest 5 (MD5)

Rivest, Shamir, Adelman (RSA) public-key algorithm

Diffie-Hellman key exchange RC4-40

Open Caveats—Cisco IOS Release 12.2(9)YE

This section documents possible unexpected behavior by Cisco IOS Release 12.2(9)YE and describes only severity 1 and 2 caveats and select severity 3 caveats.

CSCdp85074

A Cisco router that is running the Resource Reservation Protocol (RSVP) may treat some conforming reserved traffic as nonconforming. This behavior may cause traffic to be improperly marked (with precedence or type of service [TOS] markings) or improperly scheduled (that is, not assigned a reserved queue/Low Latency Queueing [LLQ] or preferential Weighted Random Early Detection [WRED] precedence/Differentiated Services Code Point [DSCP]). This condition occurs if the ip rsvp flow-assist interface configuration command and Weighted Fair Queueing (WFQ), Class-Based Weighted Fair Queuing (CBWFQ), LLQ, or WRED precedence/DSCP are configured on an interface.

Workaround: Remove the ip rsvp flow-assist interface configuration command from the configuration on the interface.

CSCdu07646

When TCP packets with window size 0 are continuously sent from the Multilayer Switch Feature Card (MSFC2) to the router, the router may fail to complete a configuration load. This condition occurs when an Access Control List (ACL) configuration is transferred through a cut-and-paste procedure using a Telnet relay.

There are no known workarounds.

CSCdu22576

A Cisco router that is implementing the Downstream Physical Unit (DSPU) feature may reload because of a loop that is observed when the router is replying to a Simple Network Management Protocol (SNMP) request.

Workaround: Do not query the dspuSapType fields of the Cisco DSPU MIN using SNMP.

CSCdv39447

The Flash MIB implementation for a High End System (HES) in Cisco IOS software does not provide correct information for the following objects:

- ciscoFlashCode

- ciscoFlashChipDescr

- ciscoFlashDeviceInitTime

There is no workaround.

CSCdv56287

Cisco Express Forwarding (CEF) does not work with IP Security (IPSec). Packets are fast-switched instead of being switched by Cisco Express Forwarding (CEF).

There are no known workarounds.

CSCdw23620

High cpu utilisation on a 7206(NPE 200) with 12.2.(5) may be caused by a service-policy. Excessive interrupts may cause the router to reload.

CSCdw27097

When the router is configured for IPSec or GRE+IPSec links packet fragmentation is handled in the process path when fast switching or CEF is enabled. Similar behavior was observed on c2600 & c3600 series routers.

CSCdw37371

A 7400 router crashes when a service-policy with WRED is attached to the ATM PVC. However, it does not crash immediately. It happens after a lot of configuration changes, involving attachment and detachment of service policies as well as forwarding traffic. It is noticed that the crash happens indeterministically - not necessarily with RED policy alone. It is also observed with C7200 router running 12.2 (6.8)T image.

No known workaround exists.

CSCdw50463

DSR drops on tty line during the set up of x28 profile

This works in 12.1(9) but not in 12.2.1b, 12.0.7XK1, 12.1.1T or 12.2(6)

CSCdw51754

A Cisco router may crash while running ip nat translation processing LDAP.

CSCdw59016

A 7400 router reloads when a service-policy is attached to an ATM PVC and after getting out from the configuration mode.

CSCdw65511

squeezing a bootflash of size ~65MB might cause High CPU utilization. Will update this section with further details.

CSCdw79279

If a member PVC in an atm bundle is not added at the same time as bundle creation, all the members may go to state INACTIVE when the main interface is reset (shut/no shut). Problem seen only for the 7500.

Workaround: Add all members when the bundle is first created.

CSCdw89255

Remote dlsw router doing sdlc/dlsw conversion with multidropped atm devices may hang. The last input/last output timers increment continually and a debug sdlc packet indicates that RR is not sent to the remote device.

Workaround is to shur/no shut the serial interface

CSCdx02106

When MLPoFR/ATM is configured, interleaving functionality (LFI) may not work properly. There is no workaround.

CSCdx07358

Under rare circumstances, a Cisco router running IOS 12.2(7) may reload due to a bus error at an invalid address such as 0xFFDF000D:

System returned to ROM by bus error at PC 0x611D2FAC, address 0xFFDF000D

There is no known workaround at this time.

CSCdx11848

Stuck mbgp entries with no valid path may cause RPF (Reverse Path Forwarding) failures for multicast traffic.

CSCdx17233

There is a severe memory leak when doing SNMP V1 testing, and may cause router to reload. There is no workaround.

CSCdx22158

On Cisco IOS Release 12.2(S), a router with a VAM card encrypting a large amount of traffic over an extended period of time may reload.

There is no workaround.

CSCdx23494

If you manually change the Message Digest 5 (MD5) keyword during a Border Gateway Protocol (BGP) session, the BGP session is reset. This behavior makes it impossible to dynamically manage security parameters in a network.

There is no workaround.

CSCdx26656

In any 12.2 release L2TP Dial-out with callback cases, when the calls initiated by LNS side, Virtual interface of LNS failed to accept sent CONFACK during vpdn/ppp callback negotiating.

There is no workaround.

CSCdx70480

On a Cisco 7400 series router, the monitor feature in VDM does not work properly.

When a tunnel is created and VDM is use, it shows in the report screen IKE=0 and IPSec=1. The TopN screens are empty and have no tunnel, and all the graph that related to ipsec / ike are empty (contain no data).

There are no known workarounds.

Resolved Caveats—Cisco IOS Release 12.2(9)YE

All the caveats listed in this section are resolved in Cisco IOS Release 12.2(9)YE. This section describes only severity 1 and 2 caveats and select severity 3 caveats.

CSCdz71127

Cisco routers and switches running Cisco IOS software and configured to process Internet Protocol version 4 (IPv4) packets are vulnerable to a Denial of Service (DoS) attack. A rare sequence of crafted IPv4 packets sent directly to the device may cause the input interface to stop processing traffic once the input queue is full. No authentication is required to process the inbound packet. Processing of IPv4 packets is enabled by default. Devices running only IP version 6 (IPv6) are not affected. A workaround is available.

Cisco has made software available, free of charge, to correct the problem.

Obtaining Technical Assistance

Cisco provides Cisco.com as a starting point for all technical assistance.

Technical Assistance Center

The Cisco TAC is available to all customers who need technical assistance with a Cisco product, technology, or solution. Two types of support are available through the Cisco TAC: the Cisco TAC Web Site and the Cisco TAC Escalation Center.

Inquiries to Cisco TAC are categorized according to the urgency of the issue:

Priority level 4 (P4)—You need information or assistance concerning Cisco product capabilities, product installation, or basic product configuration.

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

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

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

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

Cisco TAC Web Site

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

http://www.cisco.com/tac

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

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

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

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

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

Cisco TAC Escalation Center

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

To obtain a directory of toll-free Cisco TAC telephone numbers for your country, go to the following URL:

http://www.cisco.com/warp/public/687/Directory/DirTAC.shtml

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