. Hence, the desired speed and negotiation must be configured explicitly using the following commands: •speed auto: auto-negotiated 1Gbps (this is because no speed is specified and we are defaulting to advertise 1G). •speed auto 1G full/ speed 1G: auto-negotiated 1Gbps (note that per BASE-T standard, 1G must be negotiated. When above command is executed new interface is created called mirror0 which can be used with tcpdump to see data plane traffic. What surprised me at the beginning when I started my adventure with Arista switches is the limited functionality of debugs. This functionality is limited to a few commands, as presented below

Which command will successfully configure Ethernet5 to be 40Gbps on an Arista 7150-52 switch? A. An Arista 7150-52 dos not support 40Gbps B. Since Ethernet 5 is a 10Gbps port, 40Gbps is not possible. C. Arista(config-if-Et5)#speed forced 40gfull D. Arista(config-if-Et5)#speed 40gfull Correct Answer: 1) Overview. This document explains the optical connectivity involved in 40G optical QSFP for short reach (40GBASE-SR4), on multimode fibres. The standard specifies MPO12 (or MTP12) as connector to the SR4 QSFP, which employs traditionally 12 fibres, but 40G only need 8 (4 pairs) to carry the 4 parallels bidirectional paths Arista uses Ansible, bringing NetOps and DevOps together. Not just that, it helps the company get the most out of Arista switches by integrating with Ansible and bringing Ansible's strength, simplicity, and agility to its network.
