• Series: Arista 7160
• Form Factor: 1 RU (Rack Unit)
• Airflow: Front-to-back airflow (denoted by the “-F” in the model number)
• Port Configuration:
• 48 x 1/10/25GbE SFP+ and SFP28 ports
• Each port supports 1G, 10G, or 25G speeds.
• 6 x 40/100GbE QSFP+ or QSFP28 uplink ports
• Each QSFP+ port supports 40GbE or 100GbE speeds.
• QSFP28 ports can be broken out into 4 x 10GbE or 4 x 25GbE connections for added flexibility.
• Performance:
• Switching Capacity: 6.4 Tbps (Terabits per second)
• Forwarding Rate: 2 Bpps (Billion packets per second)
• Latency: Low-latency design, suitable for high-performance environments, with typical latencies as low as 450ns.
• Buffering:
• Packet Buffer: 16 MB of shared buffer memory, dynamically allocated to handle traffic bursts effectively.
• Layer 2 and Layer 3 Capabilities:
• Layer 2 Features:
• VLAN support with IEEE 802.1Q VLAN tagging, supporting up to 4096 VLANs.
• Spanning Tree Protocol (STP), Rapid STP (RSTP), and Multiple STP (MSTP).
• Link Aggregation Control Protocol (LACP) for port bundling.
• Support for Jumbo Frames (up to 9216 bytes).
• Layer 3 Features:
• Full support for IPv4 and IPv6 unicast and multicast routing.
• Protocol support for OSPF, BGP, IS-IS, and RIP.
• Virtual Routing and Forwarding (VRF) for network segmentation.
• Equal-Cost Multi-Path (ECMP) routing with up to 128-way paths for load balancing.
• Advanced Features:
• VXLAN: Hardware support for VXLAN for network virtualization and Layer 2 overlay.
• Quality of Service (QoS):
• 8 egress queues per port.
• Support for traffic prioritization, policing, shaping, and scheduling for traffic management.
• Security:
• Access Control Lists (ACLs) for filtering at Layer 2, Layer 3, and Layer 4.
• Control Plane Policing (CoPP) to protect the CPU from excessive or malicious traffic.
• Management and Automation:
• Operating System: Runs Arista’s Extensible Operating System (EOS), which includes:
• eAPI (Extensible API) for RESTful access and automation.
• Zero Touch Provisioning (ZTP) for automated, initial configuration.
• CloudVision integration for centralized management, automation, and telemetry.
• Telemetry:
• LANZ (Latency Analyzer) for microburst and latency monitoring.
• Supports real-time streaming telemetry and sFlow for traffic analysis.
• Power and Environmental:
• Power Supply: Dual, hot-swappable, redundant power supplies (AC or DC options).
• Typical Power Consumption: Approximately 250W.
• Cooling: Hot-swappable, redundant fans with front-to-back airflow.
• Physical Dimensions:
• Dimensions: 1.75 inches (4.45 cm) height x 19 inches (48.26 cm) width x 16 inches (40.64 cm) depth.
• Weight: Approximately 17 lbs (7.7 kg).
