The Cisco Nexus 5672UP Switch (Figure 1) is a 10 and 40 Gigabit Ethernet (40-Gbps on uplink and network-facing ports) switch offering wire-speed performance for up to seventy-two 10 Gigabit Ethernet ports (using Quad Small Form-Factor Pluggable [QSFP] breakout cables). The Cisco Nexus 5672UP Switches are Layer 2 and 3 nonblocking 10 and 40 Gigabit Ethernet and FCoE-capable switches with up to 1.44 Terabits per second (Tbps) of internal bandwidth. The Cisco Nexus 5672UP offers 48 fixed 1 and 10 Gigabit Ethernet ports, of which the last 16 ports (highlighted in orange on the chassis for easy identification) are unified ports. All 48 fixed ports support classical Ethernet and FCoE. In addition, the 16 unified ports provide 8-, 4-, and 2-Gbps Fibre Channel, as well as 10 Gigabit Ethernet and FCoE connectivity options. The Cisco Nexus 5672UP also offers 6 ports of 40 Gbps using QSFP transceivers for Ethernet and FCoE support. The Cisco Nexus 5672UP has three fan modules and two power supplies. The Cisco Nexus 5672UP supports VXLAN in bridging and routing modes on all ports at line rate, enabling the migration of virtual machines between servers across Layer 3 networks. The switch also offers up to 15 buffer-to-buffer credits per port, helping provide SAN extension of up to 3.7 kilometers at 8-Gbps Fibre Channel speed assuming full Fibre Channel frame size of 2112 bytes.
