STACKING NOTE: The c9300L does NOT include stacking ports by default. Please order the C9300L-STAK-KIT2-M with every C9300L switch that you plan to deploy in a stack. That kit includes two stacking ports and a 50cm stacking cable.

Catalyst 9300-M Deployment Best Practices

Before powering on devices or connecting an uplink port to the LAN, ensure to follow the steps outlined below or watch this short video.

The above video will link to a MS390 but the steps and information are the same for the C9300-M.

Configure your Dashboard Network

To add devices to your Meraki dashboard network please refer to the Creating a Dashboard Account and Organization document.

Check and Set Network Firmware

Ensure that the switch network is set to the correct firmware version. As of Feb 2024 CS16(GA) is the recommended version. Recommended versions are subject to change and are available in each dashboard by navigating to Organization > Firmware Upgrades

You can refer to Managing Firmware Upgrades for steps to set network firmware to the desired version.

Check and Configure Upstream Firewall Settings

If a ﬁrewall is in place, it must allow outgoing connections on particular ports to particular IP addresses. The most current list of outbound ports and IP addresses for your particular organization can be found under Help → Firewall info. The help button is located on the top right corner of any dashboard page. For more information refer to Upstream Firewall Rules for Cloud Connectivity.

Stacking

For stacking please refer to this section Stack Cabling Installation

Assigning an IP Address

All switches must be assigned routable IP addresses. These IP addresses can be dynamically assigned via DHCP or statically assigned. C9300 switches can support a total count of 1000 VLANs per stand-alone switch or switch stack. VLAN ID 1-1000 are configured by default, however, the active VLANs can be changed via the local status page or dashboard. When installing an C9300, it is important to ensure that any DHCP services or IP address assignments used for management fall within the active VLAN range.

Note: To utilize any VLANs outside of 1-1000 on a Catalyst Meraki C9300, the switch or switch stack must have ALL of its trunk interfaces set to an allowed vlan list that contains a total that is less than or equal to 1000 VLANs, including any of the module interfaces that are not in use. For example: If a switch needs to utilize VLANs 1,100-200,300-400,2100-2200,3000-3100, EVERY trunk interface on that switch must be configured with that allowed VLAN list or a subset of it.
The easiest method to do this is to perform the following:

Navigate to Switch > Switch ports
in the search bar use the following search term depending on if it is a stack or a single switch:
1. switch:"{name of switch}" is:trunk
2. stack:"{name of stack}" is:trunk
Select all trunks configured with the allowed VLANs of 1-1000
set to new list including new range of VLANs. (example: 1,100-200,300-400,2100-2200,3000-3100)
Click Update

Note: For the C9300X/L series, if you receive an error a "Validation failed: This switch is limited to 1000 VLANs" error when adding switches to a network, please use the VLAN Database feature to configure the active VLANs on the network.

Dynamic Assignment

When using DHCP, the DHCP server should be configured to assign a static IP address for each MAC address belonging to a Meraki switch. Other features of the network, such as 802.1X authentication, may rely on the property that the switches have static IP addresses.

Please make sure that the DHCP server used for providing a management IP address to the switch has an available address pool that falls within the active VLAN range.

Static Assignment

Static IPs can be assigned using the local status page on each switch. For more information on how to configure static IP from the local status page refer to this documentation.

Static IP via DHCP Reservations

Instead of associating each Meraki switch individually to configure static IP addresses, an administrator can assign static IP addresses on the upstream DHCP server. Through “DHCP reservations,” IP addresses are “reserved” for the MAC addresses of the Meraki switches. Please consult the documentation for the DHCP server to conﬁgure DHCP reservations.

Check upstream VLAN configuration

Ensure the upstream switch/router port is configured properly and there is no VLAN mismatch.

Check STP configuration

Meraki-managed C9300 series switches run a single instance of MST out of the box. Please read MS Best Practices prior to deployment.

NOTE: If you plan to deploy Meraki switches into an existing Catalyst network running PVST/PVST+/Rapid-PVST, please refer to this document for interoperability . To migrate your existing Catalyst switches to MSTP, please see Configuring Spanning Tree on Meraki MS Switches for more information.

Boot-up Process and Firmware Upgrades

This section provides a detailed guide on what to expect during the boot-up and firmware upgrade process. The following image illustrates the various stages the switch will undergo during a firmware upgrade, which includes a system reboot. When a switch is powered-on, or rebooted from the Dashboard, it will only go through the stages of the System boot-up process.

The status of the Dashboard-connectivity and the local status page (LSP) availability in each of these stages are also covered in the illustration and the table below.

* The durations stated in the illustration above were measured using a 6-member stack of 48-port switches. The actual time required for system boot-up and configuration will also depend on the stack size, port density and any user-defined configuration.

The following table offers another view on what to expect from the Blue Beacon and System LED as the switch progresses through these stages. For an exhaustive list of system states, please refer to the section on LED Indicators in the Meraki-managed mode.

Stage	System status	Blue Beacon LED	System LED	Dashboard status	Local Status Page (LSP) status (see details here)
Firmware download & installation	Firmware download and upgrade in progress.	Solid blue	Blinking green	Switch is connected to and managed by the Dashboard.	LSP is accessible and can be used to manage the switch.
