Cisco Catalyst WS-C4948-10GE. Switch type: Managed, Switch layer: L2. Basic switching RJ-45 Ethernet ports quantity: 48. MAC address table: 55000 entries, Switching capacity: 136 Gbit/s. Networking standards: IEEE 802.1D,IEEE 802.1p,IEEE 802.1Q,IEEE 802.1s,IEEE 802.1w,IEEE 802.1x,IEEE 802.3,IEEE.... Rack mounting, Form factor: 1UThe Cisco Catalyst 4948 10 Gigabit Ethernet Switch is a wire-speed, low-latency, Layer 2 to 4, 1-rack-unit (1RU), fixed-configuration switch for rack-optimized server switching. Based on the proven Cisco Catalyst 4500 Series hardware and software architecture, the Cisco Catalyst 4948 10 Gigabit Ethernet Switch offers exceptional performance, bandwidth, and reliability for low-density, multilayer aggregation of high-performance servers and workstations. High performance and scalability of intelligent network services is made possible with dedicated specialized resources known as ternary content addressable memory (TCAM). Ample TCAM resources (64,000 entries) enable high feature capacity, providing wire-speed routing and switching performance with concurrent provisioning of services such as quality of service (QoS) and security and helping ensure scalability for today's network requirements with ample room for future growth.
