Cisco 3745 Ser IOS ENT BASE Feature Pack

3745 Ser IOS ENT BASE Feature Pack To date and for the Cisco 3700 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.
