Description

Cisco IOS® Software Release 11.2F is based on the main base code of Cisco IOS 11.2(2) and was released in November 1996. Cisco IOS Software Release 11.2, Cisco IOS 11.2F, and Cisco IOS 11.2P characterized the Next Generation of Release Process (NGRP) release model.

Cisco IOS Software Release 11.2F is an Early Deployment (ED) release. This release focuses on delivering new features and platforms to market, and has greater unknowns than a more mature major release. As such, it should only be used for initial "point" deployment of new features.

Target Market

Cisco Systems, Inc. released Cisco IOS Software Release 11.2F for all active platforms.

Product Support

Cisco IOS Software main releases support all active Cisco shipping products.

Related Cisco IOS Releases

The early deployment releases based on Cisco IOS Software Release 11.2 regularly synchronizes with Cisco IOS Software Release 11.2 to catch base code bug fixes.

Product/Feature Integration

New products and features were added to each subsequent maintenance release of Cisco IOS Software Releases 11.2P, 11.2F, and all the ED releases based on Cisco IOS 11.2. Cisco IOS 11.2 major release main line did not provide any additional features other than the ones with which it was first customer shipped (FCS). For more information, see the following pages:

Maintenance Releases

Cisco IOS Software Release 11.2 is currently using a 13-week release model. A maintenance release is delivered once every 13 weeks. An interim build is executed once every three weeks. For more information, see the Cisco IOS Software Release 11.2 .

Interim Builds

Interim builds are not recommended and are not fully tested. Customers will only be provided with interim builds when a critical defect renders the maintenance release unusable. For more information, see the Software Releases page.

7-week maintenance cycle: Prior to Cisco IOS Software Release 11.2(12)P
13-week maintenance cycle: Cisco IOS Software Release 11.2P uses a 14-week release model. A maintenance release is delivered once every 14 weeks. An interim build is executed once every three weeks.

Maintenance Release Synchronization Points

Cisco IOS Software Release 11.2F provided time-based maintenance releases. For more information, see the Projected Release Dates for Cisco IOS Software Product Bulletin.

Recommended Migration

If currently using The recommended upgrade path is to
Cisco IOS Software Release 11.1(x) Cisco IOS Software Release 11.2 or 12.0
Cisco IOS Software Release 11.2 Cisco IOS Software Release 11.3 or 12.0
Cisco IOS Software Release 11.2P Cisco IOS Software Release 11.3T, 12.0, or 12.0T
Cisco IOS Software Release 11.2F Cisco IOS Software Release 11.3 T or 12.0T

The migration path is the logical superseding software. The uniqueness of each network requires that customers verify support for hardware, features, and protocols prior to a massive network upgrade. For more information, see the Projected Release Dates for Cisco IOS Software Product Bulletin.

Comments

[an error occurred while processing this directive]

Cisco IOS Software Release 11.2F is the combination of Cisco IOS 11.2M and Cisco IOS 11.2P. In addition to new Cisco IOS Software features that are directly added to the F line with each maintenance release, Cisco IOS Software Release 11.2F also synchronizes with the main line and the P line to inherit bug fixes and new hardware.

By virtue of its nature, Cisco IOS Software Release 11.2F was the least stable of all trains in the NGRP model train. Among the three, it was the richest in features and platforms.

[an error occurred while processing this directive]

Due to stability and code quality concerns, Cisco IOS Software Release 11.2F stopped shipment at Cisco IOS 11.2(5)F. The code was internally reworked and a new release model based on only two trains was born with Cisco IOS Software Release 11.3.
