The Cisco Sup 720-3BXL integrates a high-performance 720-Gbps switch fabric with a new routing and forwarding engine into a single module. The integrated switch fabric provides up to 40-Gbps full-duplex capacity per slot, allowing it to support third-generation high-performance, high-density Gigabit Ethernet and 10-Gigabit Ethernet interfaces as well as all existing LAN, WAN, and services modules, including the widely deployed FlexWAN and optical services modules to address a broad range of WAN edge aggregation deployments from DS-0 through OC-48/STM-16.
The Cisco Sup 720-3BXL builds on the proven Cisco Express Forwarding architecture by supporting centralized forwarding (Cisco Express Forwarding) and distributed forwarding (distributed Cisco Express Forwarding) to provide a highly scalable and cost-effective platform.
The Cisco Sup 720-3BXL delivers a modular, resilient, scalable, and secure Layer 2 or Layer 3 solution by:
Enabling advanced IP services such as MPLS, IPv6, and quality of service (QoS)
Supporting high-performance, third-generation Ethernet interfaces
Delivering predictable and scalable system performance up to a sustained 400 Mpps using distributed forwarding cards (DFCs)
Scaling hardware-capable Forwarding Information Base (FIB) table entries to 1 million routes
Supporting all three generations of Ethernet line cards, optical services modules, FlexWAN, and services modules for investment protection
Delivering up to 40-Gbps full-duplex capacity per slot
Delivering 200-Mpps hardware-based IPv6 using DFCs
Providing for 256,000 NetFlow entries
