Assigning IP Addresses to MR72s

All gateway MR72s (MR72s with Ethernet connections to the LAN) must be assigned routable IP addresses. These IP

addresses can be dynamically assigned via DHCP or statically assigned.

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 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 Assignment

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 MR72 either through a PoE switch or a PoE Injector.

If using a PoE switch, plug an Ethernet cable into the MR72'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 MR72

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.
