The Cisco Catalyst 4948E Ethernet Switch is built from the start to deliver class-leading, full-featured server-access switching. The switch offers forty-eight 10/100/1000 Gbps RJ45 downlink ports & four 1/10 Gigabit Ethernet uplink ports & is designed to simplify data center architecture & operations by offering service provider-grade hardware & software in a one Rack Unit (1RU) form factor optimized for full-featured Top-of-Rack (To R) data center deployments. The Cisco Catalyst 4948E, with its advanced multicast support, is optimized for multimedia applications. It supports Protocol Independent Multicast (PIM), Source-Specific Multicast (SSM), & Pragmatic General Multicast (PGM), providing end users with additional scalability to support multimedia applications. Also supported are Internet Group Management Protocol (IGMP) snooping & Multicast Listener Discovery (MLD) snooping in hardware, enhancing performance & reducing network traffic by allowing a switch to dynamically add & remove hosts from a multicast group. The Cisco Catalyst 4948E offers superior per-port Qo S features to help ensure that network traffic is classified, prioritized, & scheduled optimally to efficiently manage bandwidth-intensive multimedia & time-sensitive & mission-critical applications. The Cisco Catalyst 4948E can classify, monitor, & mark incoming packets, allowing the administrator to differentiate traffic flows & enforce policies. Sharing, shaping, & strict-priority configurations determine scheduling of egress traffic. ...

The Firewall Services Module (FWSM) is an integrated security module for Cisco Catalyst 6500 Series switches & 7600 Series routers that provides stateful Layer 7 filtering capabilities. The Self-Defending Network is Cisco Systems long-term strategy to allow organizations to identify, prevent, & adapt to threats using security that is integrated into all aspects of their connected business processes-incorporating secure connectivity, threat defense, & trust & identity technologies. The FWSM is a critical element of the Cisco Threat Defense System
- its unique integration of robust security services with network intelligence offers scalable, resilient protection from threats. Investment protection is the primary metric by which all next-generation switches are judged. No longer are CEOs & CIOs seeking to perform wholesale equipment replacements for performance upgrades within their networks. Equipment vendors will be required to perform upgrades to equipment by simply changing switch fabrics & adding additional higher-performance line modules. The FWSM helps to preserve a companys existing investment in Cisco Catalyst switches by adding to the existing devices, rather than rebuilding the entire network for security purposes. Network virtualization blends the economics & efficiencies of shared systems with the integrity, performance, & security of independent systems. The virtualized FWSM delivers multiple firewalls on one physical hardware platform. Network administrators can configure, deploy, & manage these firewalls as if they were separate devices. They can also partition & manage resources independently, & allocate different quantities to specific applications. Network virtualization technology allows corporations to not only increase network resource usage & exert more control over resources & their allocation, but also to gain flexibility & speed in scaling the resources. Using virtualization to reduce the number of physical devices in a network significantly reduces the cost & complexity of managing a network infrastructure.
