Though Arista Networks is a relative newcomer in the data center and cloud networking markets, the company has already had considerable success. In this book, renowned consultant and technical author Gary Donahue (Network Warrior) provides an in-depth, objective guide to Arista’s lineup of hardware, and explains why its network switches and Extensible Operating System (EOS) are so effective.
Anyone with a CCNA or equivalent knowledge will benefit from this book, especially entrenched administrators, engineers, or architects tasked with building an Arista network. Is Arista right for your data center? Pick up this guide and find out.
Topic highlights include:
SysDB: the EOS system database that holds state, statuses, and variables
Multichassis Link Aggregation (MLAG): for linking a port-channel to multiple switches instead of just one
Latency Analyzer (LANZ): the interface-buffer troubleshooting tool with a reporting granularity of one millisecond
VM Tracer: for adding, changing, and removing VLANs without human interaction
Zero-Touch Provisioning (ZTP): for remote switch configuration
Hardware advantages: including merchant silicon, low-latency networking, and power consumption

The animal on the cover of Arista Warrior is the African Harrier-Hawk (Polyboroides typus). It lives in sub-Saharan Africa and sometimes moves seasonally to West Africa. It prefers forest and woodland environments that have some water nearby, and tends to build its home out of sticks in a large gap in trees or in rocky crevices.
The African Harrier-Hawk is a medium-sized bird of prey that grows up to 65 cm in length and has a wingspan of 160 cm. As a young bird, its body color is brown, but as they mature, they become light grey. Other notable physical characteristics of this bird are that the tips of its wings are black with a white stripe in the middle and its belly has thin black and white stripes. It’s an effective hunter not only because of its size, but also because of its double-jointed legs, which it uses to take hold of its prey and to climb. It tends to eat small mammals, the eggs of small birds, chicks, reptiles, frogs, and sometimes oil palm fruit.
Typically a silent bird, an adult African Harrier-Hawk has a weak call. It whistles su-eeeee-ooo or suee-suee, and when near its nest it gives off a high-voiced wheep-wheep-wheep. The young in the nest, on the other hand, tend to give off a rapid ki-ki-ki-ki-ki sound.
