Product Review

The Cisco N9K-X9736C-FX offers impressive scalability with up to 2 million IPv4 route entries, support for 100-Gigabit Ethernet QSFP28 ports, and advanced L2/L3 networking capabilities, catering to high-demand network environments. However, its IPv6 host entry capacity is limited to 32,000, which may pose constraints in heavily IPv6-dependent infrastructures. Additionally, the module's power consumption at 607W and a weight of 14.38 lbs reflect its substantial performance capabilities but require careful consideration for energy efficiency and rack space planning.


The Cisco N9K-X9736C-FX is a line card designed for high-density, high-speed 100-Gigabit Ethernet networking, suitable for a wide range of applications from data centers to high-performance computing environments. This module is compatible with the Cisco Nexus 9000 series switches, offering advanced features and capabilities to meet the demands of modern network infrastructures. At its core, the N9K-X9736C-FX features 36 ports of 100-Gigabit Ethernet QSFP28, providing ample connectivity for devices and uplink connections. This high port density is complemented by a comprehensive suite of hardware specifications designed to optimize network performance, scalability, and reliability. The module supports up to 2 million IPv4 LPM route entries, and between 1,900 to 1 million IPv6 LPM route entries, ensuring efficient routing and handling of traffic across complex network topologies. Additionally, it can accommodate up to 2 million IPv4 and 32,000 IPv6 host entries, facilitating direct communication between a large number of devices. With support for up to 512,000 MAC address entries, the N9K-X9736C-FX can effectively learn and store the addresses of connected devices, aiding in swift packet forwarding. It also supports up to 131,000 multicast routes and has IGMP snooping groups ranging from 4,000 to 32,000 with Virtual Port Channel (VPC) and 8,000 to 32,000 without VPC, enhancing its capabilities in managing multicast traffic. In terms of network segmentation and security, the module can support up to 4,096 VLANs and up to 16,000 VRF instances, allowing for extensive virtual network partitioning and isolation. It also offers up to 512 port channels with up to 32 links each, facilitating link aggregation for increased bandwidth and redundancy. The N9K-X9736C-FX is designed for high availability and resilience, featuring up to 64 Equal-Cost Multipath (ECMP) paths, 4 to 32 active Cisco SPAN instances for network monitoring, and up to 490 HSRP groups for router redundancy. It supports up to 64 MST instances and up to 4,000 RPVST instances for advanced spanning tree protocols. For network virtualization, it can handle up to 10,000 tunnel endpoints and VXLAN physical servers per LAN, providing the flexibility needed for modern data center architectures. The module's weight is 14.38 lbs, and it operates with a typical power consumption of 607 W. It boasts a Mean Time Between Failures (MTBF) of 420,050 hours, indicating its reliability and durability. Key features include: - Hot-swappable capabilities, allowing for maintenance or upgrades without disrupting network operations. - Port-side intake airflow, ensuring efficient cooling and optimal performance. - L2/L3 networking capabilities, supporting a wide range of protocols and networking functions.
