Product Review

The Cisco 7600-ES20-GE3C Ethernet Services Module offers a notable forwarding rate of over 40 million packets per second (Mpps) and supports a variety of SFP modules (SFP-GE-S, SFP-GE-L, SFP-GE-Z), enhancing its flexibility for different network requirements. However, its maximum power consumption of 489 W and a requirement for a minimum Cisco IOS Release 12.2SRB might limit its deployment in environments with strict energy efficiency standards or older network infrastructures. Additionally, its compatibility with all Cisco 7600 series routers, except the Cisco 7603, alongside features like online insertion and removal (OIR) support, make it a versatile option for network upgrades or expansions, despite the potential for increased operational costs due to its power requirements.


The Cisco 7600-ES20-GE3C is a versatile and high-performance module designed for the Cisco 7600 series routers, delivering exceptional speed and reliability for demanding network environments. This product overview focuses on its hardware specifications, providing a comprehensive look at its capabilities and features. At the heart of the Cisco 7600-ES20-GE3C are 20 Gigabit Ethernet SFP ports, designed to accommodate a variety of SFP modules including SFP-GE-S, SFP-GE-L, and SFP-GE-Z, ensuring a wide range of connectivity options. Despite its high port density, the module ensures efficient operations with a maximum power consumption of only 489 W. The device is powered by a PXF processor and comes with 128 MB of DRAM, which significantly reduces latency, enhancing the performance of time-sensitive applications. It also includes a Distributed Forwarding Card (DFC) 3C, which is integral in achieving a high forwarding rate of over 40 million packets per second (Mpps) for both Layer 3 and Layer 4 traffic. -
  • Supports a diverse range of SFP modules for increased flexibility in network design.
  • -
  • Features 20 Gbps of switch fabric connectivity through two fabric channels, enhancing data throughput and system reliability.
  • -
  • Includes online insertion and removal (OIR) support, facilitating upgrades and maintenance without significant network disruption.
  • The module's performance is further underscored by its ability to manage up to 8,000 queues per port, with a total of 16,000 queues across the device. This extensive queuing capability allows for sophisticated traffic management and prioritization, ensuring optimal performance for all types of network traffic. With packet memory of up to 512 MB, the Cisco 7600-ES20-GE3C can handle large volumes of data, supporting a round-trip buffer time of up to 200 ms. This is particularly beneficial in environments where data integrity and timely delivery are critical. The module's aggregate bandwidth capacity stands at 10 Gbps, matched with its support for two 20 Gbps fabric channels, facilitating seamless data flow through the network. The module is compatible with all Cisco 7600 series routers, with the exception of the Cisco 7603 router, and requires a minimum of Cisco IOS Release 12.2SRB. It operates efficiently within a temperature range of 0 °C to 40 °C and can function in environments with up to 90% noncondensing humidity, ensuring reliability across various operating conditions. License options for the Cisco 7600-ES20-GE3C include the 76-ES20-BASIC-LIC, which covers basic IPv6 support, and the 76-ES20-ADVIP-LIC for advanced IP features, providing flexibility in configuring the module according to specific network requirements.
