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. MS390 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 MS390, 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 an MS390, 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:
1. Navigate to Switch > Switch ports
2. 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
3. Select all trunks configured with the allowed VLANs of 1-1000
4. set to new list including new range of VLANs. (example: 1,100-200,300-400,2100-2200,3000-3100)
5. Click Update
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.
