Cisco IOS Software Releases 12.2 SR

Cisco IOS Software Release 12.2SR is the premier Cisco IOS Software for delivering industry-leading Carrier Ethernet, Broadband Aggregation and Subscriber Services, and MPLS Provider Edge functionality for next generation Service Provider edge, Enterprise MAN / WAN, and Federal networks that run the Cisco 7600 Series Routers, Cisco 7200 Series Routers, and the Cisco 7301 Router.

Key highlights of Release 12.2(33)SRC, the latest customer release of Release 12.2SR, include Cisco ISG Session Control Stateful Switchover (SSO) and Enhanced Fast Software Upgrade (EFSU) support for PPP Sessions, IP Sessions, and IP Interface Sessions for Cisco 7600 Series Routers. These advances ensure continuous network operations and minimal interruption of dynamic session services during a route processor switchover, whether the switchover is due to the upgrade or downgrade of a complete Cisco IOS Software image or new service deployment.
