Cisco Nexus 5672UP - Switch - L3 - Managed - 32 x 1 Gigabit / 10 Gigabit SFP+ + 16 x combo 1 Gigabit / 10Gb Ethernet / 2/4/8Gb Fibre Channel / FCoE SFP+ + 6 x 40Gb Ethernet / FCoE QSFP+ (breakout compatible) - rack-mountable Cisco | N5K-C5672UP

The Cisco Nexus 5672UP is a wire-rate Layer 2 and Layer 3 switch offering 10 Gigabit Ethernet and unified ports (UP) in a compact one-rack-unit form factor. It is optimized for 10 Gigabit Ethernet top-of-rack access, Cisco Fabric Extender (FEX) aggregation, Virtual Extensible LAN (VXLAN) segmentation, and LAN-SAN convergence. It delivers high performance, operational efficiency, and design flexibility for traditional, virtualized, and cloud environments.

• Optimization for virtualization and cloud deployments
  Today, high-performance servers deployed in the cloud can support many more virtual machines and workloads than ever before. The requirement to deploy new servers on demand puts additional strain on the network fabric. The Cisco Nexus 5600 platform switches address this challenge by providing scalability and performance, making it an excellent platform for meeting current and future needs.
• Density and resilience
  Built for today's data centers, the switches are designed just like the servers they support. Ports and power connections are at the rear, close to server ports, helping keep cable lengths as short as possible and delivering to rack servers benefits traditionally offered only on blade servers. Hot-swappable power and fan modules can be accessed from the front panel, where status lights offer an at-a-glance view of switch operation. Front-to-back or back-to-front cooling is consistent with server designs, supporting efficient data center hot and cold-aisle designs. Serviceability is enhanced with all customer-replaceable units accessible from the front panel.
• Energy efficiency
  The Cisco Nexus 5600 platform switches help data centers operate within their space, power, and cooling parameters while reducing their carbon footprints. The switch power supplies are also capable of maintaining 90 percent efficiency at load conditions of as low as 25 percent utilization. This capability allows the switch to make efficient use of power while still being appropriately sized to support the conditions of a full system load.
• Low latency
  Cut-through switching enables these switches to support approximately 1 microsecond of port-to-port latency for any packet size with features enabled.
• Intelligent Cisco Switched Port Analyzer (SPAN) and Encapsulated SPAN (ERSPAN)
  SPAN and ERSPAN can be used for troubleshooting and robust monitoring of traffic. The SPAN and ERSPAN capabilities are nondisruptive, with only extra bandwidth capacity used for SPAN and ERSPAN traffic. Enhancements include more efficient allocation of bandwidth to SPAN and ERSPAN traffic whereby any fabric bandwidth not used for data traffic can be allocated to SPAN or ERSPAN traffic.
• Flexible buffer management
  The Cisco 5600 platform switches support a 25-MB packet buffer shared by every 3 ports of 40 Gigabit Ethernet or every 12 ports of 10 Gigabit Ethernet. The flexible buffer management capability allows for dynamic tuning of the shared and dedicated buffer size in the event of congestion.
• Multicast enhancements
  Line-rate Layer 2 and 3 multicast throughput for all frame sizes is also supported on these switches. They offer optimized multicast replication through the fabric and at the egress point. Support is provided for 32,000 multicast routes and for Internet Group Management Protocol (IGMP) snooping tables in hardware. Multicast enhancements include flow-based hashing for multicast traffic over a PortChannel and enhanced Bidirectional Protocol-Independent Multicast (Bidir-PIM) support.
