PRODUCT IDENTIFICATION

The product family detailed in this document encompasses a series of high-performance Layer 2+ and entry-level Layer 3 Ethernet switches engineered for scalable Medium Enterprise, Campus Access, and Carrier Edge aggregation deployments. The defining architectural characteristic of this platform series is the hardware-forwarded MAC address table size, available in two primary SKU tiers: 16,384 (16K) and 32,768 (32K) entries.

CORE INTERNAL TOPOLOGY

The forwarding plane is constructed around a single, non-blocking Ethernet switching ASIC. The MAC learning and aging logic is processed in hardware, ensuring wire-speed performance regardless of table utilization. The 16K variant addresses standard access layer requirements, while the 32K variant doubles the Layer 2 domain capacity, allowing for larger broadcast domains or deeper MAC learning in complex multi-tenant edge networks.

SWITCHING SUBSYSTEM CAPABILITIES

- HARDWARE FORWARDING: All switching, filtering, and VLAN assignment occur at line rate within the packet forwarding engine.

- MAC MANAGEMENT: Configurable aging timer (10-1,000,000 seconds), static MAC entry programming, and MAC address move protection.

- LAYER 2 PROTOCOLS: Full support for GVRP, MVR, STP/RSTP/MSTP, and Link Aggregation Control Protocol (LACP).

- SCALABILITY: The 32K model supports up to 4K active VLANs and 32K independent MAC entries simultaneously, mitigating overflow risks in dense aggregation topologies.

OPERATIONAL ADVANTAGES

- Predictable performance: Table exhaustion results in packet flooding, not forwarding engine lockup.

- Silent failover: Graceful restart of management plane does not clear the dynamic MAC table.

- Hardware learning: Prevents CPU intervention for each new source MAC, preserving CPU for routing protocols and management.
