關於產品

Product Information

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 and four 1/10 Gigabit Ethernet uplink ports and is designed to simplify data center architecture and operations by offering service provider-grade hardware and software in a one Rack Unit (1RU) form factor optimized for full-featured Top-of-Rack (ToR) 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), and Pragmatic General Multicast (PGM), providing end users with additional scalability to support multimedia applications. Also supported are Internet Group Management Protocol (IGMP) snooping and Multicast Listener Discovery (MLD) snooping in hardware, enhancing performance and reducing network traffic by allowing a switch to dynamically add and remove hosts from a multicast group.The Cisco Catalyst 4948E offers superior per-port QoS features to help ensure that network traffic is classified, prioritized, and scheduled optimally to efficiently manage bandwidth-intensive multimedia and time-sensitive and mission-critical applications. The Cisco Catalyst 4948E can classify, monitor, and mark incoming packets, allowing the administrator to differentiate traffic flows and enforce policies. Sharing, shaping, and strict-priority configurations determine scheduling of egress traffic.
