Cisco 7600 Series Route Switch Processor 720
Product Overview
The Cisco
®
7600 Series Route Switch Processor 720 (RSP 720) is specifically designed to deliver
high scalability, performance, and fast convergence required for today’s and tomorrow’s
demanding voice, video, data, and mobility (quadruple-play) services. The Cisco 7600 RSP 720
offers service providers and enterprises true service convergence with the ability to manage a wide
variety of applications over a range of access mediums using a single platform (Figure 1).

The Cisco 7600 RSP 720 uses the same high-performance 720-Gbps crossbar switch fabric as
that used by the Cisco Catalyst
®
6500 Series Supervisor Engine 720 and combines it with a new,
revised, and application-specific integrated circuit (ASIC)-based forwarding engine. This single
module delivers 40 Gbps of switching fabric capacity per slot, supporting 4-port 10 Gigabit
Ethernet and 48-port 10/100/1000 density line cards. With hardware-enabled forwarding for IPv4,
IPv6 Unicast and Multicast, and Multiprotocol Label Switching (MPLS), the Cisco RSP 720 can
provide high-speed central forwarding with rich packet processing features such as access control
lists (ACLs), quality of service (QoS), MPLS VPNs, and more. Combining the Cisco 7600 RSP 720
with distributed forwarding cards (DFCs), the total system performance can scale up to 400 Mpps.
The Cisco 7600 RSP 720 delivers a rich set of IP features in hardware for applications such as
subscriber aggregation, IP forwarding, Layer 2 and Layer 3 MPLS VPNs, and Ethernet over MPLS
(EoMPLS) with quality of service (QoS) and security features.
The Cisco 7600 RSP 720 comes integrated with two new daughter cards:
●
Policy Feature Card (PFC-3C or PFC-3CXL) – Performs Layer 2 and Layer 3 forwarding in
hardware with constant performance, even with intensive features enabled such as ACLs,
QoS, generic routing encapsulation (GRE), or Network Address Translation (NAT); the
Policy Feature Card performs the following functions:
◦
Performs Layer 2 and Layer 3 forwarding
◦
Enforces ACL functions
◦
Performs QoS policing and marking
