What is NX-OS?
NX-OS is a network operating system that was designed for Cisco's Nexus-series Ethernet switches and MDS-series Fibre Channel storage area network switches. Based on Wind River Linux, NX-OS evolved from Cisco's SAN-OS and has a similar command-line interface (CLI) as its IOS.
Among the features of NX-OS is that it lets you segment Nexus 7000 Series switches into virtual device contexts (VDCs), which provide fault isolation, an administration plan, separation of data traffic and better security. It also enables Virtual Port Channels (vPCs), which let you use an EtherChannel across two upstream switches, so that you can use all available uplink bandwidth.
Another benefit of NX-OS is that it lets you perform maintenance, update and software certification without a service interruption.
Finally, NX-OS supports IEEE 802.1AE link-layer cryptography with 128-bit Advanced Encryption Standard (AES) cryptography. It also includes other important security features, such as access control lists (ACLs) and port security.
