Based on Cisco® Cloud Scale technology, the Cisco Nexus® 93108TC-FX3P Switch is a multigigabit-capable, fixed switch in the next-generation Cisco Nexus 9300 platform. Cisco Multigigabit Ethernet technology supports bandwidth speeds from 100Mbps to 10 Gbps over traditional Category 5e/6 cabling. This addresses the need for the exponential increases in bandwidth being driven by the enormous growth of 802.11ac Wave 2 and Wi-Fi 6 without having to replace current cabling infrastructure. The switch is built on modern-system architecture designed to provide high performance, support cost-effective deployments, and meet the evolving needs of growing mid-size to large enterprise customers.
Cisco provides two modes of operation for Cisco Nexus 9000 Series Switches. Organizations can deploy Cisco Application Centric Infrastructure (Cisco ACI®) or Cisco NX-OS mode. Cisco ACI is a holistic, intent-driven architecture with centralized automation and policy-based application profiles. It provides a robust transport network for dynamic workloads and is built on a network fabric that combines time-tested protocols with new innovations to create a highly flexible, scalable, and resilient architecture of low-latency, high-bandwidth links. This fabric delivers a network that can support the most demanding and flexible data center environments. Designed for the programmable network, the Cisco NX-OS operating system automates configuration and management for customers who want to take advantage of the DevOps operation model and tool sets.
With optimized efficiency, simplified operation and installation, and a wide array of device versatility, the Cisco Nexus 93108TC-FX3P Switch provides investment protection for customers in an ever-changing data-centric and increasingly connected market. The expansive feature set includes 40MB of intelligent buffering, support for voice VLANs, and a full-featured Layer 2 and Layer 3 Application-Specific Integrated Circuit (ASIC).

The Cisco Nexus 93108TC-FX3P Switch (Figure 1) is a compact 1 RU switch that supports 2.16 Tbps of bandwidth and 1.2 billion packets per second (bpps). Offering flexible port speed configurations, the switch supports 48 ports of 100M/1/2.5/5/10G BASE-T on the downlinks. The 6 uplink ports support 40/100G QSFP 28. The 93108TC-FX3P is well suited for network customers requiring more versatility and flexibility in networking speeds.
Cisco Nexus 93108TC-FX3P Switch
The Cisco Nexus 9300-FX3 series switches provide the following features and benefits:
● Architectural flexibility
◦ Industry-leading software-defined networking (SDN) solution Cisco ACI support
◦ Support for standards-based VXLAN EVPN fabrics, inclusive of hierarchical multisite support (Refer to VXLAN Network with MP-BGP EVPN Control Plane for more information.)
◦ Three-tier BGP architectures enabling horizontal, nonblocking IPv6 network fabrics at web-scale
◦ Segment routing that allows the network to forward Multiprotocol Label Switching (MPLS) packets and engineer traffic without Resource Reservation Protocol (RSVP) Traffic Engineering (TE). It provides a control-plane alternative for increased network scalability and virtualization.
◦ Comprehensive protocol support for Layer 3 (v4/v6) unicast and multicast routing protocol suites, including BGP, Open Shortest Path First (OSPF), Enhanced Interior Gateway Routing Protocol (EIGRP), Routing Information Protocol Version 2 (RIPv2), Protocol Independent Multicast Sparse Mode (PIM-SM), Source-Specific Multicast (SSM), and Multicast Source Discovery Protocol (MSDP).
● Extensive programmability
◦ Day-0 automation through Power On Auto Provisioning, drastically reducing provisioning time
◦ Industry-leading integrations for leading DevOps configuration management applications, including Ansible, Chef, Puppet, SALT, Extensive Native YANG, and industry-standard OpenConfig model support through RESTCONF/NETCONF
◦ Pervasive APIs for all switch CLI functions (JSON-based RPC over HTTP/HTTPs)
● High scalability, flexibility, and security
◦ Flexible forwarding tables support up to two million shared entries on FX3 models. Flexible use of TCAM space allows for custom definition of Access Control List (ACL) templates.
◦ MAC Security (MACsec) and CloudSec (VTEP-to-VTEP encryption) support on all ports of Cisco Nexus 9300-FX3 models with speeds greater than or equal to 1 Gbps, which allows traffic encryption at the physical layer and provides secure server, border-leaf, and leaf-to-spine connectivity
● Intelligent buffer management
◦ The platform offers Cisco’s innovative intelligent buffer management, which offers the capability to distinguish mice and elephant flows and apply different queue management schemes to them based on their network forwarding requirements in the event of link congestion.
◦ Intelligent buffer management functions are:
Approximate Fair Dropping (AFD) with Elephant Trap (ETRAP). AFD uses ETRAP to distinguish long-lived elephant flows from short-lived mice flows. AFD exempts mice flows from the dropping algorithm so that mice flows will get their fair share of bandwidth without being starved by bandwidth-hungry elephant flows. Also, AFD tracks elephant flows and subjects them to the AFD algorithm in the egress queue to grant them their fair share of bandwidth.
ETRAP measures the byte counts of incoming flows and compares this against the user-defined ETRAP threshold. After a flow crosses the threshold, it becomes an elephant flow.
Dynamic Packet Prioritization (DPP), which provides the capability of separating mice flows and elephant flows into two different queues so that buffer space can be allocated to them independently. Mice flows that are sensitive to congestion and latency can take priority in the queue and avoid reordering, allowing elephant flows to take full link bandwidth.
● RDMA over Converged Ethernet – RoCE support
◦ Platform offers lossless transport for RDMA over Converged Ethernet with support of DCB protocols:
Priority-based Flow Control (PFC) — to prevent drops in the network and pause frame propagation per priority class
Enhanced Transmission Selection (ETS) — to reserve bandwidth per priority class in a network contention situation
Data Center Bridging Exchange Protocol (DCBX) — to discover and exchange priority and bandwidth information with endpoints
The platform also supports Explicit Congestion Notification (ECN), which provides end-to-end notification per IP flow by marking packets that experienced congestion, without dropping traffic. The platform is capable of tracking ECN statistics of the number of marked packets that have experienced congestion.
● Hardware and software high availability
Virtual Port-Channel (vPC) technology provides Layer 2 multipathing through the elimination of Spanning Tree Protocol. It also enables fully utilized bisectional bandwidth and simplified Layer 2 logical topologies without the need to change the existing management and deployment model.
◦ The 64-way Equal-Cost MultiPath (ECMP) routing enables the use of Layer 3 fat-tree designs. This feature helps organizations prevent network bottlenecks, increase resiliency, and add capacity with little network disruption.
◦ Advanced reboot capabilities include hot and cold patching
◦ The switch uses hot-swappable Power-Supply Units (PSUs) and fans with N+1 redundancy.
● Purpose-built Cisco NX-OS software operating system with comprehensive, proven innovations
Single binary image that supports every switch in the Cisco Nexus 9000 series, simplifying image management. The operating system is modular, with a dedicated process for each routing protocol: a design that isolates faults while increasing availability. In the event of a process failure, the process can be restarted without loss of state. The operating system supports hot and cold patching and online diagnostics.
Cisco Data Center Network Manager (DCNM) is the network management platform for all NX-OS-enabled deployments, spanning new fabric architectures, IP Fabric for Media, and storage networking deployments for the Cisco Nexus―powered data center. Accelerate provisioning from days to minutes, and simplify deployments from day 0 through day N. Reduce troubleshooting cycles with graphical operational visibility for topology, network fabric, and infrastructure. Eliminate configuration errors and automate ongoing change in a closed loop, with a templated deployment model and configuration compliance alerting with automatic remediation. Real-time health summary for fabric, devices, and topology. Correlated visibility for fabric (underlay, overlay, virtual, and physical endpoints), including compute visualization with VMware.
Network traffic monitoring with Cisco Nexus Data Broker builds simple, scalable, and cost-effective network test access points (TAPs) and Cisco Switched Port Analyzer (SPAN) aggregation for network traffic monitoring and analysis.
