Cisco IOS Software Release 15.1(2)S for Cisco 7600 Series Routers
Product Bulletin No.: 657641
®

The Cisco 7600 Series Routers are optimized for the transition to the IP Next-Generation Network (IP
NGN) with complete features for mobile transport, business services, video, and residential triple play
®

(data, voice, and video). Cisco IOS Software Release 15.1(2)S continues to deliver on the vision with
new operational features, improved scale, network resiliency solutions, and support for new services. You
can take advantage of Cisco’s latest features and invest with confidence in the Cisco 7600 Series Router.
New Features
More than 25 new features have been added, including the following important enhancements:

Y.1731 performance monitoring for standardized measurements of frame loss, frame delay, and availability
across Carrier Ethernet eliminates expensive test equipment, improves service-level agreements (SLAs), and
simplifies operations.

Dynamic Ethernet service activation creates zero-touch provisioning of Layer 2 connections with Ethernet
accounting through RADIUS to create new service opportunities for wholesale, business, and mobile
markets.

Bidirectional Forwarding Detection (BFD) scale improvements for Ethernet Services Plus (ES+) provide
support for more BFD sessions as well as faster failure detections to improve SLAs while saving on capital
expenditures (CapEx).

Intermediate System-to-Intermediate System (IS-IS) IPv4 loop-free alternate Fast Reroute provides automatic
detection and rerouting for sub-50–msec recovery.

Border Gateway Protocol (BGP) IPv6 Prefix Independent Convergence (PIC) at the edge and core provides
faster route-table convergence at higher scale so that new service opportunities for IPv6 can now be
delivered with the SLAs that customers expect.

Real-Time Protocol (RTP) metrics support for inline video monitoring extends the benefits of in-band
performance management of video traffic for IPTV, cable, and video contribution networks.

Upgrade Paths
Cisco IOS Software Release 15.1(2)S inherits all the features from Releases 12.2(33)SRE, 15.1(1)S, and 15.0(1)S.
Each Cisco IOS 15 S software release is classified as either a standard-support or extended-support release. A
standard-support release has a sustaining support lifetime of 1 year from first customer shipment (FCS) with two
scheduled rebuilds. Cisco IOS Software Release 15.1(2)S is a standard-support release.
