An example of a USART. A universal synchronous and asynchronous receiver-transmitter (USART, programmable communications interface or PCI) [1] is a type of a serial interface device that can be programmed to communicate asynchronously or synchronously.
The Nexus 5000 series, a.k.a. N5K, is a range of 5 models 1U or 2U rack-switches offering 20 to 96 interfaces running on 1 or 10 Gbit/s Ethernet and 10 Gbit/s FCoE interfaces. They can be used with the above-mentioned Nexus 2000 series fabric extender. The 5000-series offer carrier-grade layer2 and layer3 switching as well as FCoE capabilities [15]
A limitation of Port Aggregation Protocol is that all the physical ports in the aggregation group must reside on the same switch. Cisco's 6500 and the 4500E platforms, remove this limitation using Virtual Switching System (VSS), [1] which allows port channels to be split between two chassis. PAgP is not supported in Cisco Nexus Switches.
Packet Tracer is a cross-platform visual simulation tool designed by Cisco Systems that allows users to create network topologies and imitate modern computer networks.The software allows users to simulate the configuration of Cisco routers and switches using a simulated command line interface.

NX-OS is a network operating system for the Nexus-series Ethernet switches and MDS-series Fibre Channel storage area network switches made by Cisco Systems. It evolved from the Cisco operating system SAN-OS, originally developed for its MDS switches. [1] It is based on Wind River Linux and is inter-operable with other Cisco operating systems.
This series can support interfaces up to 100 Gigabit Ethernet in speed and redundant supervisor modules, power supplies and fans. [17] The Cisco Catalyst 9400 Series is a chassis-based access and distribution switch family. This series can support interfaces up to 40 Gigabit Ethernet in speed and redundant supervisor modules, power supplies and ...
100GAUI-1 is a 100 Gbit/s 1-lane electrical interface defined in 802.3ck Annex 120F/G with a nominal signaling rate for each lane of 53.125 GBd using PAM4 modulation and RS-FEC(544,514) so suitable for use with 100GBASE-CR1, 100GBASE-KR1, 100GBASE-SR1, 100GBASE-DR, 100GBASE-FR1, 100GBASE-LR1 PHYs.
