Designed for the Arista 7800R modular chassis family, it supports AES-256-GCM bulk encryption across MACsec, IPsec, and VXLANsec simultaneously with zero forwarding penalty — making it the ideal choice for secure DCI, WAN interconnect, and hyperscale fabric buildouts.\u003cbr\u003e\u003cbr\u003eEach port supports 400G native or 4x 100G breakout, and a deep-buffer VOQ architecture (~40 ms per ingress port) eliminates head-of-line blocking for mixed elephant and mice flow workloads. The FlexRoute Engine enables full Internet routing table scale in hardware, while Algorithmic ACLs and accelerated sFlow at 400G provide granular policy control and traffic visibility. Compatible with 7804R, 7808R, 7812R, and 7816R chassis.
