Description

The Arista 7280R3 Series with Encryption is a 1RU fixed-configuration data centre switch router built for secure data centre interconnect, large-scale cloud leaf and spine designs, EVPN/VXLAN overlays, internet peering and carrier edge services. This model pairs wire-speed MACsec, IPsec and VXLANsec encryption with deep packet buffers.

It provides 32 x 100G QSFP100 ports and 4 x 400G OSFP ports, with 4.8 Tbps throughput (9.6 Tbps full duplex), 2 Bpps forwarding and latency from 3.8 us. An 8 GB packet buffer and 64 GB of system memory support large routing tables. This -FLX-R SKU is the FLX licence tier covering over 256K routes, MPLS and VXLAN, with rear-to-front airflow and two hot-swap AC power supplies in a 1+1 arrangement. Typical power draw is 535 W, with a 851 W maximum.

The 400G OSFP ports accept 400GBASE-CR8, AOC, SR8, DR4, XDR4, FR4, 2FR4, LR4, PLR4 and ZR optics, with 200G and breakout options to 100G, 50G and 25G. The 100G QSFP ports take 100GBASE-SR4, LR4, CWDM4, FR, DR, PSM4, ER4L, AOC and CR4, as well as 40G QSFP+ optics.
