Cisco IOS Software Release 11.3(4)HA

Introduction

This Product Bulletin describes the features in Cisco IOS(TM) software release 11.3(4)HA. This release is specific to supporting the Cisco ISR 3303 Integrated SONET Router. It should be used in conjunction with Product Bulletin titled, Cisco IOS Software Release 11.3(4)T.

New Features

11.3(4)HA is an Early Deployment (ED) release. This release is focused on delivering SONET path protection, SONET APS, Ethernet interface support and DS1 (T1) Facility support for the Cisco ISR 3303 platforms.

Detailed Information

11.3(4)HA is for operation only on the ISR 3303. The ISR 3303 is a hybrid SONET ADM (Add-Drop Multiplexer) and Cisco Router that supports redundant or non-redundant OC-3 interfaces as the Network side interface, and supports 8 DS1 transmission interfaces and 8 10BaseT ethernet interfaces. The system consists of a chassis, one or two SAM modules, and a fan unit. When configured as a redundant system, the ISR supports redundancy for the system processor, IOS*, system memory, routing/bridging hardware, SONET hardware and DS1 processing.

For more detailed information about the platforms and features being delivered in 11.3(4)HA, please reference the following document.

Product Numbers and Descriptions

Cisco IOS Software Release 11.3(4)HA can be ordered using the following product numbers.

Note on system configuration:

When there is a need to order a SYSTEM, enter the ISR3303-R-SC or ISR3303-NR-SC ordering items. By specifying these part numbers, the shipped order will come with the chassis, the appropriate number of SAMS (R=2, NR=1). Also specify separately software as part of the order of a system. the latest version of supported IOS (in this case, 11.3.(4)HA). Documentation and an installation and accessories package are also included with the system order. The remaining part numbers should only be used for ordering replacement parts, or spares, for an existing system.

Feature Sets, Images and Minimum Memory Requirements

The ISR system only supports the feature sets listed within this document. The 11.3(4)HA image is specific to the ISR 3303 and currently the only supported image. The system is equipped with the necessary memory to support all features and functionalites of 11.3(4)HA. No additional memory is required.
