Cisco IOS ENT PLUS Feature Pack for 2691 Integrated Services Router

IOS ENT PLUS Feature Pack for 2691 Integrated Services Router Overview
To date and for the 2600 Series Multiservice Access Routers, every release of Cisco IOS software feature sets has been made available as spare parts. A Cisco IOS software spare part is shipped as a single image on CD-ROM or other removable media. They are purchased by end customers upgrading from the base feature set and by Cisco partners staging configuration of routers.

Moving forward, Cisco will migrate to a model where a Cisco IOS software spare part CD-ROM includes all current releases of the feature set. This CD-ROM will be referred to as a Cisco IOS Feature Pack and already exists for a number of feature sets. Customers only need to specify platform and feature set when ordering a Cisco IOS Feature Pack. It will no longer be necessary to specify a particular release.

The contents of the Cisco IOS Feature Packs will be updated on a quarterly basis and will include the latest four maintenance releases from all open mainline release trains and all releases from the current T-train.

Note that purchase of a Cisco IOS software feature pack includes an entitlement to deploy any release of the selected feature set, not only those included on the CD-ROM. If the desired release is not included on the CD-ROM, it can be downloaded from cisco.com or it can be obtained from your Cisco partner or customer services representative.

Also, note that only the most commonly deployed feature sets will be sold as Cisco IOS Feature Packs. Other feature sets remain available as traditional spare parts.

Contents of a Cisco IOS Feature Pack
The Cisco IOS Feature Pack consists of two deliverables:
-A software entitlement document.
-A CD-ROM.

Ordering a Cisco IOS Feature Pack requires knowledge of the desired router platform and desired feature set. There is no need to specify a particular release, the CD-ROM will include all releases available on the global pricelist.

The Software Entitlement Document
The software entitlement document is a written record of the right to operate the feature set and should be maintained in a safe place.

The CD-ROM
The CD-ROM provides a number of releases of the feature set, along the following guidelines:
-The latest four maintenance releases from all active mainline release trains (currently 12.0, 12.1, 12.2 and 12.3)
-All T-releases and special releases from the current T-train, or not yet collapsed (currently 12.2(15)ZJ and releases from 12.2T).

The number of images on a Cisco IOS Feature Pack will vary, depending on the chosen feature set and platform. Newer feature sets or platforms will initially only have one or two images on the CD-ROM. Discontinued feature sets will only see additions from Mainline trains.
