What is the switching capacity and throughput?

Switching capacity is 288 Gbps (up to 176 Gbps effective), with throughput of 180 Mpps and packet forwarding rate of 131 Mpps. This non-blocking performance handles high enterprise loads efficiently.

What are the latency specifications?

Latency measures 5 µs at 1000 Mbps and 3 µs at 10 Gbps, ensuring minimal delays for real-time applications. Combined with 64,000 MAC entries and 10,000-byte jumbo frames, it optimizes data center edge performance.

Does it support Layer 3 routing and how many routes?

Yes, as a Layer 3 managed switch, it supports 32,768 IPv4 routing entries and 16,384 IPv6 entries, plus MPLS and LACP. This enables advanced routing without external devices in aggregation layers.

What is the form factor and power setup?

1U rack-mountable with front-to-back airflow. Power uses internal hot-plug supplies (maximum 2, not included) at AC 100-240V 50/60 Hz, with 1 expansion slot for modularity.

How is the switch managed?

Managed via SmartMC embedded tool with web-based GUI, plus serial/USB console. Supports IEEE 802.3/1Q/D/X/ad standards, IRF stacking for high availability in enterprise stacks.
