Question

Hi,

I'd like to lookup the MAC address of a remote RU955 device via CLI.

Is the above possible?

Thanks

You should try: ifconfig

root@Teltonika-RUT955:~# ifconfig
br-lan    Link encap:Ethernet  HWaddr 00:1E:42:25:3F:D8
          inet addr:192.168.1.1  Bcast:192.168.1.255  Mask:255.255.255.0
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:1105 errors:0 dropped:0 overruns:0 frame:0
          TX packets:231 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0
          RX bytes:170361 (166.3 KiB)  TX bytes:52205 (50.9 KiB)

Thanks,

Is there a way to request this remotely when SSH isnt possible via a UCI SMS command?

If you need MAC address send SMS text message: admin01 monitoring_status

Note: <<admin01>> is default RUT password and should be replaced by your admin password.

Hello,

You can SSH into the router and view the ARP cache via shell using the arp or ip neigh commands, depending on which output your prefer. You should have a similar outcome to this;

root@Teltonika-RUT955:~# arp
IP address       HW type     Flags       HW address            Mask     Device
192.168.1.103    0x1         0x2         ac:e2:d3:00:00:00     *        br-lan
192.168.1.151    0x1         0x2         18:d6:c7:00:00:00     *        br-lan

root@Teltonika-RUT955:~# ip neigh
192.168.1.103 dev br-lan lladdr ac:e2:d3:00:00:00 REACHABLE
192.168.1.151 dev br-lan lladdr 18:d6:c7:00:00:00 REACHABLE

His this is the MAC addresses of devices connected to the RUT955.

What command gives me the MAC address of the device itself?

If you are just looking for device's own ifconfig should do it.
