The MR12 and MR58 wireless access points have two Ethernet ports that can be used to connect the device to a wired network. However, a static IP can only be set on the primary Ethernet interface.
This article will discuss:
- Identifying the primary Ethernet port
- Behavior differences between primary and secondary ports
- Determining which port is being used
Assigning a static IP
Identifying the Primary Ethernet Port
The primary Ethernet port is directly adjacent to the power connector and is labeled as Uplink.
The primary Ethernet port is located on the bottom-left side of the AP and is labeled as ETH0.
Behavior differences between primary and secondary ports
Primary (Ethernet 0)
This interface is capable of receiving power using PoE and can be assigned a static IP address. It is also capable of 10/100/1000Mbps speeds. It is intended for connecting the MR12 to the rest of the network.
Secondary (Ethernet 1)
This interface can only receive an IP from DHCP and is not able to receive power using PoE. It is only capable of 10/100 speeds. It is still able to connect to the Meraki Cloud Controller if the Primary connection is down, but is intended for used by a wired client. To allow use by a wired client, please refer to our documentation regarding Extending the LAN with a Wireless Mesh Link.
Determining which port is being used
The simplest way to determine which port is being used is to physically look at the device, and refer to the diagrams above. If you are not near the device, the easiest way to determine if the secondary port is being used is by looking at the AP Dashboard. Navigate to Monitor > Access points and click the AP in question. Look under Status for LAN IP #. If the # = 1, then the AP is connected using the primary port. If # = 2, then the AP is connected using its secondary port.
Assigning a static IP
A static IP can be assigned to the AP's primary interface in two ways.
1. In Dashboard, go to Monitor > Access points and select the AP in question.
2. Click the Edit icon.
3. On the page that appears, next to IP type select Static IP.
4. Enter the appropriate settings and click Save.
