Cisco is the worldwide leader in networking for the Internet. Cisco provides the broadest line of solutions for transporting data, voice and video within buildings, across campuses, or around the world. Cisco solutions ensure that networks both public and private operate with maximum performance, security, and flexibility.
The Cisco Catalyst 4500 Series 48-Port 10/100/1000 RJ-45 module has efficient power draw.
Chassis and Line Card Support : The Cisco Catalyst 4500 Series Supervisor Engine V can be deployed in single-chassis, nonredundant mode in the Cisco Catalyst 4503/4503-E and Cisco Catalyst 4506/4506-E chassis, or in redundant mode as an option in the Cisco Catalyst 4507R (slots 1 and 2)/4507R-E/4507R+E (slots 3 and 4) and Cisco Catalyst 4510R (slots 1 and 2)/4510R-E/4510R+E (slots 5 and 6) chassis. Table 1 shows the performance of the Supervisor Engine V for each chassis.
Predictable Performance and Scalability : The Cisco Catalyst 4500 Series Supervisor Engine V delivers a 96-Gbps switching fabric with a 72-mpps forwarding rate in hardware for Layer 2-4 traffic. Switching performance is independent of the number of route entries or Layer 3 and 4 services enabled. Hardware-based Cisco Express Forwarding routing architecture allows for increased scalability and performance. Table 2 provides a comparison of the performance and scalability features of all of the Cisco Catalyst 4500 Series Enhanced Layer 3 Supervisor Engines.
Supervisor Engine V Redundancy for Business Resiliency : The Cisco Catalyst 4500 Series was designed to maximize desktop user uptime, with noninterrupted hardware switching. The Cisco Catalyst 4507R, 4507R-E, 4507R+E, 4510R, 4510R-E, and 4510R+E support 1+1 supervisor redundancy, using the Supervisor Engine V. The primary supervisor is active and is responsible for normal system operation. The other supervisor serves as a secondary standby, monitoring the operation of the primary supervisor.
IPv6 Support : IPv6 is important for the future of IP networking and is critical for the expansion of IP address space in the future. IPv6 capability is required by many companies and is being mandated by governments worldwide. IPv6 has been supported on the Cisco Catalyst 4500 Supervisor Engine V since Cisco IOS Software Release 12.2(20) EW with software-based forwarding.
