The MS450 is an aggregation switch built for very high-density, high-bandwidth environments such as data centers and large campus cores. With twelve 40GbE QSFP+ ports and a 1.36 Tbps non-blocking switching fabric, it's designed to sit above stacks of access-layer switches like the MS355 and consolidate their uplinks into a resilient, high-throughput core.

The MS450-12 has twelve 40GbE QSFP+ ports plus two 100GbE QSFP28 fiber uplink ports, along with a dedicated RJ45 management port. The two QSFP28 ports are rated for 100Gbps operation only; they do not downshift to 40Gbps.

Yes. The MS450 includes two dedicated 100G hardware stack ports delivering up to 400 Gbps of stacking bandwidth, and up to eight MS450 switches can be stacked together for high-availability aggregation. Note that this is physical stacking only; flexible stacking (as used on the MS425) is not supported.

Yes, the MS450 supports Layer 3 switching, including OSPF and static routing, allowing it to route between VLANs and subnets at the aggregation layer instead of relying solely on an upstream router.

Yes. Every Meraki MS450 must be paired with a Meraki switch license (Enterprise or Advanced) to be claimed into the cloud dashboard and remain manageable. Firewalls.com can help you match the right license term and tier to your MS450 hardware order.
