These release notes for the Cisco Catalyst 4224 Access Gateway Switch describe the software features provided in Cisco IOS Release 12.1(5)YI. These release notes are updated as needed.
The Cisco Catalyst 4224 Access Gateway Switch is an Ethernet switching router that provides Voice over IP (VoIP) gateway and IP telephony services. It is designed to be part of a centralized Cisco CallManager application.
To determine the version of Cisco IOS software running on your Cisco Catalyst 4224 Access Gateway Switch, log in to the Cisco Catalyst 4224 Access Gateway Switch and enter the show version EXEC command:

Novell IPX is derived from the Xerox Network Systems (XNS) Internet Datagram Protocol (IDP). The Cisco implementation of the Novell IPX protocol is certified to provide full IPX routing functionality, and it includes support for the following features:
IPX MIB (currently, read-only access is supported)
IPX Enhanced IGRP, with automatic redistribution, increased network width, and incremental SAP updates.
Routing IPX between Ethernet-emulated LANs and Token Ring-emulated LANs
Routing IPX between VLANs
IPX Multilayer Switching (MLS
For details on how to configure IPX protocol, refer to the following documentation, available online at Cisco.com:
Cisco IOS AppleTalk and Novell IPX Configuration Guide, Release 12.1
Many enterprise organizations have networks that are based on IBM mainframes and Systems Network Architecture (SNA). The Cisco bridging and IBM networking technologies enable the delivery of SNA data over routers supporting TCP/IP. For details on how to configure SNA protocol, refer to the following documentation:
Cisco IOS Bridging and IBM Networking Configuration Guide, Release 12.1
This section contains important information about Cisco IOS Release12.1(5)YI that applies to the Cisco Catalyst 4224 Access Gateway Switch:
Half-duplex mode for bisync tunneling (BSTUN) is not supported for this release.
The 12.1(5)YI release supersedes the 12.1(5)YE releases for the C4224. However, unless you intend to use the SNA functionality provided by the YI release and are currently running the latest 12.1(5)YE5 release, you do not need to upgrade at this time.
The following sections describe the documentation available for the Cisco Catalyst 4224 Access Gateway Switch. These documents consist of hardware and software installation guides, Cisco IOS configuration guides and command references, system error messages, feature modules, and other documents.
Documentation is available as printed manuals or electronic documents, except for feature modules, which are available online on Cisco.com and the Documentation CD-ROM.
Feature modules describe new features supported by Cisco IOS Release 12.1(5)YI and are updates to the Cisco IOS documentation set. A feature module consists of a brief overview of the features, benefits, and configuration tasks as well as a command reference. As updates, the feature modules are available online only. Feature module information is incorporated in the next printing of the Cisco IOS documentation set.
Feature Navigator is a web-based tool that enables you to quickly determine which Cisco IOS software images support a particular set of features and which features are supported in a particular Cisco IOS image.

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.
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:
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:
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:
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:
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.
