Description

The Arista 7280R3 with encryption is a 1RU fixed data centre switch router built for leaf, spine and data centre interconnect roles. It is also used for secure site-to-site links, internet peering and carrier edge VPN and EVPN services. This SKU is the Secure Boot enabled variant with front-to-rear airflow and dual AC power supplies.

It provides 32 x 100GbE QSFP100 ports and 4 x 400GbE QSFP-DD ports, with 4.8 Tbps (9.6 Tbps FDX) throughput, 2 Bpps forwarding and latency from 3.8 us. Deep 8 GB packet buffers and large routing tables suit demanding layer 2 and layer 3 cloud designs. Wire-speed AES-256-GCM encryption is available on the TunnelSec-capable QSFP100 ports, and the platform runs Arista EOS, which uses a feature licence for encryption.

The 100G QSFP ports accept 100G and 40G optics and DACs, while the 400G QSFP-DD ports accept 400G optics and cables. Power comes from two hot-swap 1100 W AC supplies in a 1+1 arrangement, with three hot-swap fans in an N+1 arrangement.

FAQs

Q: Does this switch need a licence for encryption?
A: It runs Arista EOS (feature licence group 3, minimum EOS 4.27.2F). Encryption is an EOS licensed feature that needs a licence file, such as LIC-FIX-3-MACSEC for MACsec.

Q: What power supplies does it use?
A: It uses two hot-swap PWR-1011 family AC supplies in a 1+1 redundant arrangement. The AC supply is rated 100-240V AC with 1100 W output at 93% Platinum efficiency.

Q: Which optics do the QSFP100 and QSFP-DD ports accept?
A: The QSFP100 ports accept 100G and 40G QSFP optics and DACs, with breakout to 4x10G or 4x25G on alternate ports. The QSFP-DD ports accept 400G optics (SR8, DR4, XDR4, FR4, 2FR4, LR4, PLR4, ZR) plus 200G and 100G optics and cables.

Q: How does this SKU differ from other 7280CR3MK variants?
A: This is the -S-F variant, which has Secure Boot enabled, front-to-rear airflow and two AC power supplies, with 32x100G QSFP and 4x400G QSFP-DD ports.

Q: Can it be managed with CloudVision?
A: Yes. It is manageable through Arista CloudVision and supports open APIs, ZTP and LANZ.
