Description

The Arista 7280R3A is a 1RU fixed data centre switch router built for internet exchanges and peering, high-performance storage, content delivery networks, carrier edge VPN services and data centre spine and leaf designs. This DCS-7280CR3AM-32S-F is the M variant, which adds TunnelSec line-rate encryption on all ports, and it uses front-to-rear airflow.

The port layout is 30 x QSFP100/200 plus 2 x QSFP200/QSFP-DD, giving 32 x 100GbE or 2 x 400G. With breakouts it scales to a maximum of 2 x 400G, 18 x 200G, 36 x 100G or 56 x 50G, 25G and 10G interfaces. System throughput is 3.6 Tbps (7.2 Tbps FDX) at 1.35 Bpps, with latency from 3.8 us and a 4 GB packet buffer. It has two hot-swap AC power supplies in a 1+1 arrangement and three hot-swap fans in an N+1 arrangement, with typical draw of 302 W and maximum 481 W excluding transceivers.

It runs Arista EOS, minimum release 4.32.1, in EOS Feature License Group 3. TunnelSec encryption (MACsec, IPsec and VXLANsec) is an EOS licensed feature and needs a licence file to enable it. The switch supports 400ZR coherent optics, uses fan tray FAN-7011H-F as the front-to-rear spare, and works with PWR-1512-AC power supplies.

FAQs

Q: Does TunnelSec encryption need a licence?
A: Yes. TunnelSec is an EOS licensed feature and needs a licence file to enable it. This M model is the TunnelSec-capable variant, and it sits in EOS Feature License Group 3.

Q: What power supplies does this model use?
A: It uses two hot-swap AC power supplies in a 1+1 redundant arrangement. The supply is the PWR-1512-AC, rated at 1500 W output on 200-240 VAC.

Q: Can the 100G ports be broken out?
A: Yes. Breakouts allow up to 2 x 400G, 18 x 200G, 36 x 100G or 56 x 50G, 25G and 10G interfaces.

Q: Does it support 400G coherent optics?
A: Yes. The two QSFP-DD ports support 400G ZR and ZR+ coherent optics for DWDM links.

Q: How does this SKU differ from other 7280R3A models?
A: The M variant adds TunnelSec encryption on all ports, and the -F suffix means front-to-rear airflow with two AC power supplies. The base R3A has no encryption.
