Check network to see if your iConnectivity interface is showing and if an IP is responding

There are many ways to check if your iConnectivity interface is showing but this version will check by IP and we can test the IP to see if it's responding correctly.

arp -a

You can copy the command above to check what IPs are avialable on your network(s).

To do follow the steps below

1. In spotlight search type terminal and open the terminal applicaton. This may seem daunting for some, like it's some FBI screen on a movie but it is very useful with the right info.
2. By default it will let you type into this box. Just paste in the arp -a written at the beginning of this section of the article.
3. Once done you should see a screen like this will all the IP addresses from your network. You may only have 1 or you might have 100. This can be very useful information to check against. 
   
   **This may take a little bit of time depending on the network, how many devices are on the network and speeds on each connected device.
   
   

This is great if you already know the IP of your interface. This will allow you to check for an interface IP.  Check out this article on how to find or set the IP of your iConnectivity interface. Once you know the IP of your device you will be able to see if that device is showing in this list in terminal. If it is you are good to test in the next step. If not, you might want to check the physical connections like the ports, cables, etc..

How to test the connection of an IP

• Open a terminal window. If you have one opened you can use the same window. Just make sure you've completed any tasks running in it from before.
• type ping then a space and then whatever the IP is you are trying to check.
  
  In this example I'm looking to ping the IP of mioXL in the image.
  
  Note: ping is just a way of saying send some test messages or check this...
• If the device is commicating you should see data lines like the below image
  
  If it's not found you will see a bunch fo messages with no found and you won't see the 64 bytes connect. If this happens double check you types the IP correctly and then start looking at the physical connections, service order and more to troubleshoot the connection.
