This product bulletin specifies the software feature sets available for Cisco 800 Series Integrated Services Routers with Cisco IOS Software Release 15.0. It also issues recommendations for flash and DRAM memory configuration
Note: This product bulletin covers the Cisco IOS Software release model changes from Cisco IOS Software Releases 12.4 Mainline and 12.4T for the Cisco 800 Series Integrated Services Routers. It does not cover individual new features. For information about new features in Cisco IOS Software Release 15.0, refer to the Cisco IOS Software pages at Cisco.com.
® Software Release 15.0 follows Release 12.4(24)T. Created for wide deployment in the world's most demanding enterprise, access, and service provider networks, Cisco IOS Software Release 15.0 provides a comprehensive portfolio of Cisco technologies, functions, and hardware support from Releases 12.4 and 12.4T, anchored by an intensive stability and testing program. Important innovations span multiple technology areas, including security, voice, high availability, IP Routing and Multicast, quality of service (QoS), IP Mobility, Multiprotocol Label Switching (MPLS), VPNs, and Cisco IOS MPLS Embedded Management.
Cisco IOS Software Release 15.0 can help you by providing new feature and hardware support more quickly than in previous Mainline (M) and Technology (T) releases, broadened feature consistency with other major Cisco IOS Software releases, more predictable new feature release and rebuild schedules, proactive individual release support policies, enhanced release numbering, and clearer software deployment and migration guidelines. Figure 1 details Cisco IOS Software Release 15.0.
Figure 1. Release 15.0 Train Map
Unlike the traditional Cisco IOS Software M and T releases, Cisco IOS Software Release 15.0 does not diverge into separate M and T software release trains. Beginning with 15.0, new releases will be available 2 to 3 times per year, delivered sequentially from a single software train. Extended Maintenance (EM) releases will be available approximately every 20 months. Standard maintenance T releases enable faster Cisco feature delivery before the next EM release becomes available.
Highlights of Releases 15 M and T follow:
• Feature inheritance from Cisco IOS Software Releases 12.4T and 12.4 Mainline
• New feature releases delivered sequentially from a single T train
• Extended maintenance new feature M release every 20 months
• Standard maintenance T releases for the latest features and hardware support before the next M release becomes available on Cisco.com
Note that rebuilds of Releases 15 M and T contain bug fixes only.
M Releases (Extended Maintenance)
• Ideal for long-term maintenance, enabling you to qualify, deploy, and remain on the release for an extended period
• Provides 44 months of support
• Incorporates features delivered in previous releases plus incremental new feature enhancements and hardware support
T Releases (Standard Maintenance)
• Short deployment releases ideal for latest new features and hardware support before the next M release becomes available
The remainder of this product bulletin provides details about Cisco IOS Software Release 15.0 availability for the Cisco 800 Series routers and the associated flash and DRAM memory requirements.
