Assigning IP Addresses to MR20s

All gateway MR20s (MR20s with Ethernet connections to the LAN) must be assigned routable IP addresses. These IP

addresses can be dynamically assigned via DHCP or statically assigned.

When using DHCP, the DHCP server should be conﬁgured to assign a static IP address for each MAC address

belonging to a Meraki AP. Other features of the wireless network, such as 802.1X authentication, may rely on the

property that the APs have static IP addresses.

Static IPs are assigned using the local web server on each AP. The following procedure describes how to set the

static IP:

1. Using a client machine (e.g., a laptop), connect to the AP wirelessly (by associating to any SSID

broadcast by the AP) or over a wired connection.

2. If using a wired connection, connect the client machine to the MR20 either through a PoE switch or a

PoE Injector. If using a PoE switch, plug an Ethernet cable into the MR20's Ethernet jack, and the other

end into a PoE switch. Then connect the client machine over Ethernet cable to the PoE switch. If using a

PoE Injector, connect the MR20 to the "PoE" port of the Injector, and the client machine to the "LAN"

port.

3. Using a web browser on the client machine, access the AP's built-in web server by browsing

to http://my.meraki.com. Alternatively, browse to http://10.128.128.128.

4. Click on the "Uplink Conﬁguration" tab. Log in. The default login is the serial number (e.g. Qxxx-xxxx-

xxxx), with no password (e.g., Q2DD-551C-ZYW3).

5. Conﬁgure the static IP address, net mask, gateway IP address and DNS servers that this AP will use on

its wired connection.

6. If necessary, reconnect the AP to the LAN.

Static IP via DHCP Reservations

Instead of associating to each Meraki AP 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 APs. Please consult the documentation for the DHCP server to

conﬁgure DHCP reservations.

You will need the following tools to perform an installation:
