Cisco IOS® Software Release 12.2S is designed for Enterprise campus and Service Provider edge networks that require world-class IP and Multiprotocol Label Switching (MPLS) services. The Cisco Catalyst® Switches and high-end routers in Release 12.2S provide secure, converged network services in the most demanding Enterprise and Service Provider environments, from the wiring closet and data center to the WAN edge.
The infrastructure innovation and technology leadership in Release 12.2S enable advanced Ethernet LAN switching, Provider Edge, Metro Ethernet, and Broadband Aggregation services through enhancements in High Availability, Security, MPLS, VPNs, and IP Routing and Services.
Release 12.2(18)SXD, the most recent release of the 12.2S family, extends the benefits of Cisco IOS High Availability to Enterprise campus, data center, and WAN aggregation networks, and Service Provider edge aggregation networks that run the Cisco Catalyst 6500 Series Switch and Cisco 7600 Series Router. These enhancements provide nonstop application availability for Enterprise business-critical services, including supply-chain management, secure transactions, IP communications, and e-business. They also provide the network resiliency that Service Providers need to extend revenue through robust Service Level Agreements. This increased availability and resiliency reduces the total cost of ownership for Enterprise and Service Provider networks while also improving their overall productivity and efficiency.
