Catalyst 9300-M Datasheet


The Catalyst 9300-M addresses the most demanding enterprise applications by combining the simplicity of the Meraki dashboard with powerful switching hardware. To satisfy high-bandwidth applications and the deployment of high-speed 802.11ax/wifi-6 access points, the Catalyst 9300-M provides multigigabit ports, 480G stacking, and modular 10/40G uplinks. The Catalyst 9300-M delivers resiliency with fast stack convergence and StackPower. The Catalyst 9300-M provides Adaptive Policy using an over-the-wire tag which segments traffic into security groups to deliver scalable security. The Catalyst 9300-M is integrated under the Meraki dashboard to provide a simply powerful solution to the most demanding wired access applications.

Adaptive Policy provides simple & scalable security policies to segment traffic using Security Groups. Security Groups are created in the dashboard using natural language such as “IOT device” & “Guest.” The security policy intent (e.g., Permit or Deny) is then simply provisioned between Security Groups which results in the segmentation of each group’s traffic. By making security policy management intuitive and scalable relative to legacy IP-address based Access Control Lists, Adaptive Policy empowers operators to confidently secure their network traffic independent of future network changes. 

By pooling & distributing power across C9300-Ms using a series of StackPower cables, StackPower provides simple and resilient power distribution across the stack.

A Catalyst 9300 switch can also be migrated to a Meraki-managed persona, where it would function as its Catalyst Meraki 9300 equivalent. For details on the migration process, please refer to our Getting started: Cisco Catalyst 9300 with Meraki Dashboard guide.

Catalyst 9300-M Licensing

Catalyst 9300-M license structure includes two feature tiers:  Enterprise and Advanced.  As with all Meraki managed switches, every Catalyst 9300-M license is available in 1, 3, 5, 7, and 10 year terms.

Catalyst 9300-M License Structure 24-Port 48-port
Advanced Features LIC-C9300-24A LIC-C9300-48A
Enterprise Features LIC-C9300-24E LIC-C9300-48E

The features available with advanced licensing are: 

In the Co-term licensing model (most existing Organizations), an Organization must either have all Catalyst 9300-M Enterprise or all Catalyst 9300-M Advanced licenses - they cannot be mixed. In the Per-device licensing model, a mix of Enterprise and Advanced can be added to a single Organization, but certain features may require all devices in a Network to have Advanced licenses, e.g. Adaptive Policy.

Note: MS390s existing in the same co-term Organization will require the same license edition (either Enterprise or Advanced) as the Catalyst 9300-M. License types cannot be mixed and will result in an incompatible license error.

For more information on licensing, refer to Meraki Licensing Models article

Subscription licensing is also available for the Catalyst 9300-M switches

Cabling Best Practices for Multi-Gigabit operations: While Category-5e cables can support multigigabit data rates upto 2.5/5 Gbps, external factors such as noise, alien crosstalk coupled with longer cable/cable bundle lengths can impede reliable link operation. Noise can originate from cable bundling, RFI, cable movement, lightning, power surges and other transient event. It is recommended to use Category-6a cabling for reliable multigigabit operations as it mitigates alien crosstalk by design.

*Note: The C9300-NM-2Y-M module is supported on C9300-24S/48S with firmware CS16.7(CS16GA2). Support for the other C9300 switch models will be added in CS16GA3.

**NOTE: The PWR-C1-1900WAC-P-M provides 1900 W output power when the nominal input voltage is 230 V. If the nominal input voltage is 115 V, then the output power is limited to 1500 W.  The power supply does not work with standard 125VAC power cords(common with 1100W and lower power supplies), you require a C21 power cable like the North American(C9K-PWR-CAB-AC-US). Also a good option is the universal C20-C21 jumper cable(C9K-PWR-CAB-AC-BL), suitable for Rack PDUs .  See Table 2 for all suitable worldwide  power cord options. Please note there are no -M versions of these cables, they must be ordered with the Cisco SKU.
