If you have changed and forgotten the IP? Not exactly through the AP GUI. However, if your AP/router Is DHCPing out numbers, then the connected SM (if it’s configured to do so) would get an IP in the appropriate range, and would be reachable through the AP over the wireless interface.
Also, you can always connect to whatever device you are physically connected to the Ethernet of. with 169.254.1.1 IP. That IP is ‘baked in’ to the ethernet of all ePMPs.
You can also use cnMaestro to configure a device which you’ve lost the IP too, assuming your wireless network is connected to the internet and some basic cnMaestro one touch info is entered.
And tools such as AngryIP can quickly scan a large range of IPs to help find a lost IP. Wireshark is another tool to see what is happening on a network.
As the last resort, there are a couple different methods of resetting a radio to factory defaults. In which case they would revert back to their factory default IPs as well.
I changed the IP of the SM to a different subnet to rectify some routing issues, though the SM is now inaccessible through the browser. So when I click the IP highlighted in the picture attached, it says ‘site cannot be reached’.
I believe I should have changed the mode of the SM from bridge to router and set a different ethernet IP and kept the wireless IP in the same range as the AP.
I can connect directly to the SM to make changes if need be, was just hoping to avoid travelling to the site.
So the network is setup as follows:
PMP Wireless: 172.31.1.xxx
PMP SM Ethernet: 10.1.3.xxx
I’ve adjusted the configuration to NAT mode for the SM.
The CCTV server that’s below the SM is in the 10.1.3.xxx range.
With the configuration I have now, I’m able to ping devices on the BMS range that are above the SM from the CCTV server.
But I’m not able to ping devices on the CCTV vlan that are above the SM from the CCTV server.
I also cant ping any devices on the SM side from the AP side.
I know all ports are open between subnets on the AP side, but do I need to open specific ports on the SM side? and is NAT the right mode for this application or is router what I should be using?
