Product Details
The Cisco Nexus 3100-V platform provides the following main benefits:
● High performance and scalability
◦ The Cisco Nexus 3100-V platform provides wire-rate Layer 2 and 3 switching of up to 2.56 terabits per second (Tbps) and up to 1.4 billion packets per second (bpps) on all ports.
◦ The Cisco Nexus 3100-V platform delivers ultra-low nominal latency (approximately 650 nanoseconds [ns]), which allows customers to implement high performance infrastructure for High-Frequency-Trading (HFT) workloads.
● Line-rate Virtual Extensible LAN (VXLAN) routing
◦ VXLAN is designed to provide the same Ethernet Layer 2 network services as VLAN does today, but with greater extensibility and flexibility.
◦ The Cisco Nexus 3100-V platform offers native line-rate VXLAN routing.
◦ The Border Gateway Protocol (BGP) Ethernet Virtual Private Network (EVPN) control plane provides scalable multitenancy and host mobility (for more information, refer to the document “VXLAN Network with MP-BGP EVPN Control Plane.
● Enhanced buffer for applications
◦ The Cisco Nexus 3100-V platform offers 16 MB of shared buffer space.
In today’s data center, application teams require the network to be flexible and capable of handling the rapid growth of applications. The Cisco Nexus 3100-V platform provides deep shared buffers (16 MB) to absorb bursts of traffic and a wide variety of applications, such as multicast feeds, voice traffic, video traffic, and healthcare applications.
◦ These deep buffers also provide flexibility to expand your network as your needs change. The shared buffers are also instrumental in situations in which one or more servers are consuming most of the bandwidth in highly oversubscribed environments.
● Higher ingress Access Control List (ACL) entries
◦ The Cisco Nexus 3100-V platform offer 16,000 ACL entries and 1000 egress ACL entries.
◦ The increased number of ingress ACL entries can be especially useful in today’s data centers, particularly in virtualized environments.
● 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 models.
◦ The 64-way Equal-Cost Multipath (ECMP) routing enables the use of Layer 3 fat-tree designs and allows organizations to prevent network bottlenecks, increase resiliency, and add capacity with little network disruption.
◦ Advanced reboot capabilities are included through In Service Software Upgrade (ISSU) and Fast Reboot capabilities.
◦ Power-Supply Units (PSUs) and fans are hot swappable.
● Purpose-built on the NX-OS operating system with comprehensive, proven innovations
◦ Power-on Auto Provisioning (POAP) enables touchless bootup and configuration of the switch, drastically reducing provisioning time.
◦ Cisco Embedded Event Manager (EEM) and Python scripting enable automation and remote operations in the data center.
◦ Advanced buffer monitoring reports real-time buffer use per port and per queue, which allows organizations to monitor traffic bursts and application traffic patterns.
◦ Ethanalyzer is a built-in packet analyzer for monitoring and troubleshooting control-plane traffic and is based on the popular Wireshark open-source network protocol analyzer.
◦ Precision Time Protocol (PTP; IEEE 1588) provides accurate clock synchronization and improved data correlation with network captures and system events.
◦ Complete Layer 3 unicast and multicast routing protocol suites are supported, including Border Gateway Protocol (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).
● Network traffic monitoring with Cisco Nexus Data Broker
◦ Build simple, scalable and cost-effective network test access point (TAP) or Cisco Switched Port Analyzer (SPAN) aggregation for network traffic monitoring and analysis.
