This model provides 96 QSFP100 ports with 9.6 Tbps of throughput and 4 Bpps forwarding, backed by a 16 GB deep packet buffer and latency from 3.8 us. The ports run at 100G natively and support breakout to 50G and 25/10G, or 40G with QSFP+ optics, for up to 192 interfaces. It is supplied with two hot-swap AC power supplies in a 1+1 configuration, four N+1 hot-swap fans and front-to-rear airflow. Typical power draw is 1003 W, rising to 1803 W at maximum.

The FLX-Lite licence covers full routing up to 256K routes, EVPN, VXLAN, Segment Routing and base MPLS LSR, and it runs Arista EOS from version 4.24.0. The ports accept 100GBASE optics and cables including SR4, LR4, CWDM4, PSM4, AOC and CR4, as well as 40G QSFP+ optics and 50G and 25G breakout cables.
