The Nexus switches and the NX-OS operating system are established high-speed switches in core structures and data centers, whereby the NX-OS is based on a Linux kernel and offers many new options. Participants will be familiarized with these special features of the NX-OS compared to the classic IOS and typical protocols such as virtual port channel (vPC) and the connection of fabric extenders (FEX) will be presented in a practical way. An optimal network design and the optimization of the protocols used play a major role here in order to be able to implement highly available structures with low downtime. Typical administration tasks such as updates during operation or system recovery are also carried out.
