DCS-7050CX3M-32S-F is the MACsec-enabled, front-to-rear airflow version of the Arista 7050CX3-32S, a 1RU switch with 32 QSFP100 ports and two SFP+ ports. It comes with two AC power supplies. DCS-7050CX3M-32S-R is the rear-to-front version, and DCS-7050CX3M-32S# is the form with configurable fans and power supplies.
MACsec (IEEE 802.1AE) adds line-rate frame encryption and authentication on the QSFP ports at 10G, 25G, 40G and 100G, using the 128-bit or 256-bit GCM-AES-XPN cipher suite with keys defined statically or derived through RADIUS. Encryption needs a license file in EOS, and LIC-FIX-2-MACSEC covers 25 to 64 MACsec-capable ports.
Throughput is up to 6.4 Tbps bi-directional at 2 Bpps, with cut-through latency of 800 nanoseconds and a 32 MB fully shared dynamic buffer. Each QSFP port runs at 100GbE, 40GbE, 4x10GbE, 4x25GbE or 2x50GbE, for up to 128 ports of 10GbE or 25GbE or 64 ports of 50GbE, and the two SFP+ ports carry 1G or 10G out-of-band and management links.
The chassis has 8 GB of memory and 8 GB of flash, three N+1 hot-swap fans and two 1+1 hot-swap power supplies. Typical draw is 398 W and the maximum is 751 W. It measures 19 x 1.75 x 22 inches (48.3 x 4.4 x 55.88 cm), weighs 26.45 lb (12 kg) and needs EOS 4.23.0 or later.
Other 7050X series switches are in the Arista switch category, including the DCS-7050SX-64-F.
