5500-48G-POE+ SI SWITCH CPNT W/2 INTF SLTS

Overview
These Gigabit Ethernet switches deliver quad-speed performance 10/100/1000 and 10 Gigabit Ethernet, as well as advanced voice-enhanced features such as Power over Ethernet (PoE), auto-voice VLAN, and Quality of Service (QoS). As a result, they are ideal for enterprise organizations seeking to build a secure, convergence-enhanced campus network. Robust IPv6 support and 10 Gigabit Ethernet uplinks future-proof an enterprise network against obsolescence. Resilient Ring Protection Protocol (RRPP), Smart Link, and Intelligent Resilient Framework (IRF) deliver 50 ms switchover and carrier-class reliability.

Features
Quality of Service (QoS)

⁍ Broadcast control: allows limitation of broadcast traffic rate to cut down on unwanted network broadcast traffic


Management

⁍ Friendly port names: allow assignment of descriptive names to ports


Connectivity

⁍ Auto-MDIX: automatically adjusts for straight-through or crossover cables on all 10/100/1000 ports


Performance

⁍ Nonblocking architecture: up to 192 Gbps nonblocking switching fabric provides wire-speed switching with up to 143 million pps throughput


Resiliency and high availability

⁍ Separate data and control paths: keeps control separated from services and keeps service processing isolated; increases security and performance


Layer 2 switching

⁍ 16K MAC address table: provides access to many Layer 2 devices


Layer 3 services

⁍ Address Resolution Protocol (ARP): determines the MAC address of another IP host in the same subnet
