Upgrading to a New Software Release

For general information about upgrading to a new software release, see Software Installation and Upgrade Procedures located at http://www.cisco.com/warp/public/130/upgrade_index.shtml.

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 12.2(13)ZF2 supports the same feature sets as Releases 12.2 and 12.2(8)T, but Release 12.2(13)ZF2 includes new features supported by the Cisco 1700 series routers.


Caution Cisco 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 will likely require an export license. Customer orders can be denied or subject to delay as a result of United States government regulations. When applicable, the purchaser/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 through Table 4 list the features and feature sets supported in Cisco IOS Release 12.2(13)ZF2.

The tables use the following conventions:

Yes—The feature is supported in the software image.

No—The feature is not supported in the software image.

In—The number in the "In" column indicates the Cisco IOS release in which the feature was introduced. For example, "12.2(13)ZF" means that the feature was introduced in 12.2(13)ZF. If a cell in this column is empty, the feature was included in a previous release or in the initial base release.


Note These feature set tables contain only a selected list of features, which are cumulative for Release 12.2(13)nn early deployment releases only (nn identifies each early deployment release). The tables do not list all features in each image—additional features are listed in the Cross-Platform Release Notes for Cisco IOS Release 12.2 T and Release 12.2 T Cisco IOS documentation.

New and Changed Information

The following sections list the new software features supported by the Cisco 1700 series routers for Release 12.2(13)ZF.

New Software Features in Release 12.2(13)ZF

The following sections describe the new software features supported by the Cisco 1700 series routers for Release 12.2(13)ZF.

Frame Relay SVCs Over ISDN

This feature supports Frame Relay (FR) switched virtual circuits (SVCs) over an ISDN line. A common use of the functionality in network topology is to put it as a backup route. This feature enables the support of current FR SVC function on an ISDN BRI interface, as if running on a serial line. FR switching does not work with this feature.

DHCP Authorized ARP

This feature enhances the Dynamic Host Configuration Protocol (DHCP) and Address Resolution Protocol (ARP) components of the Cisco IOS to limit the leasing of IP addresses to mobile users to authorized users.

A new command line interface (CLI) arp authorized command is defined to enable this feature.

Configuration Example

Consider the routers R1 and R2. R1 is the DHCP server that assigns IP addresses to the routers that are seeking IP addresses, and R2 is configured to obtain its IP address through DHCP server. Since ARP update is configured on R1, it will install a secure ARP entry in its ARP table. The arp authorized command stops any dynamic ARP on that interface. R1 will send periodic ARPs to R2 to make sure that the client is still active; the client (R2) responds with an ARP reply. The timer for the entry is refreshed on R1 upon receiving the response.

The following example shows configuration of R1 DHCP server:

ip dhcp pool testing_pool
network 10.0.0.0 255.255.255.0
lease 0 0 20
update arp
!
interface Ethernet0
ip address 10.0.0.1 255.255.255.0
half-duplex
arp authorized
arp timeout 60

The following example shows configuration of R2 DHCP client.

interface Ethernet0/0
ip address dhcp
half-duplex

The following is the output for the sh arp command on R1

R1#sh arp
Protocol  Address          Age (min)  Hardware Addr   Type   Interface
Internet  10.0.0.3                0   0004.dd0c.ffcb  ARPA   Ethernet01 
Internet  10.0.0.1                -   0004.dd0c.ff86  ARPA   Ethernet0 

The following is the output for the sh arp command on R2

R2#sh arp
Protocol  Address          Age (min)  Hardware Addr   Type   Interface
Internet  10.0.0.3                -   0004.dd0c.ffcb  ARPA   Ethernet0/02 
Internet  10.0.0.1                0   0004.dd0c.ff86  ARPA   Ethernet0/0

Important Notes

The following sections describe important notes concerning the new software features supported by the Cisco 1700 series routers for Release 12.2(13)ZF2.

Frame Relay SVCs Over ISDN

Frame Relay SVCs over ISDN is an existing feature of Cisco IOS software. To activate the Frame Relay SVCs over ISDN functionality, configure the SVCs under dialer interface or BRI interface, depending on where Frame Relay encapsulation is specified.

Caveats

Caveats describe unexpected behavior or defects in Cisco IOS software releases. Severity 1 caveats are the most serious caveats, severity 2 caveats are less serious, and severity 3 caveats are the least serious of these three severity levels.

Caveats in Release 12.2 T are also in Release 12.2(13)ZF2. For information on caveats in Cisco IOS Release 12.2 T, refer to the Caveats for Cisco IOS Release 12.2 T document. For information on caveats in Cisco IOS Release 12.2, refer to the Caveats for Cisco IOS Release 12.2 document. These documents list severity 1 and 2 caveats, and are located on Cisco.com and the Documentation CD.


Note If you have an account with Cisco.com, you can also use the Bug Toolkit to find select caveats of any severity. To reach the Bug Toolkit, log in toCisco.com and click Service & Support: Technical Assistance Center: Tool Index: Bug Toolkit. Another option is to go to http://www.cisco.com/cgi-bin/Support/Bugtool/launch_bugtool.pl


Resolved Caveats for Release 12.2(13)ZF2

Cisco IOS Release 12.2(13)ZF2 is a rebuild release for Cisco IOS Release 12.2(13)ZF. This section describes unexpected behavior that is fixed in Release 12.2(13)ZF2.

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.

This advisory is available at

http://www.cisco.com/warp/public/707/cisco-sa-20030717-blocked.shtml

Technical Assistance Center

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

Cisco TAC inquiries 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.

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

Cisco TAC Web Site

You can use the Cisco TAC Web Site 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 this URL:

http://www.cisco.com/tac

All customers, partners, and resellers who have a valid Cisco service 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 this URL to register:

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

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

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

If you have Internet access, we recommend that you open P3 and P4 cases through the Cisco TAC Web Site.

Cisco TAC Escalation Center

The Cisco TAC Escalation Center addresses priority level 1 or priority level 2 issues. 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 automatically opens a case.

To obtain a directory of toll-free Cisco TAC telephone numbers for your country, go to this 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). When you call the center, please have available your service agreement number and your product serial number.
