Cisco Meraki MS450-12 12-Port 40G QSFP+ Aggregation Switch — 2 × 100G QSFP28 Uplinks, Layer 3, 1U Rack
The Cisco Meraki MS450-12 is a fiber aggregation switch engineered for enterprise campus core and data center environments. Its twelve 40 Gigabit QSFP+ ports and two 100 Gigabit QSFP28 uplinks deliver substantial throughput at 1.36 Tbps of switching capacity, making it an efficient aggregation point for high-density access-layer deployments. Cisco Meraki cloud management provides centralized visibility and zero-touch provisioning across the entire network. The MS450-12 supports full Layer 3 routing, VRRP for warm-spare redundancy, and front-port physical stacking at 160G, with a modular power design that accepts an optional redundant PSU for mission-critical uptime requirements.
