Mikrotik - how to find out the bandwidth of connected devices on all ports at once?

Question

Mikrotik

How can I immediately find out the bandwidth of all connected devices to all mikrotika ports. Through SpeedPing you can only find out by IP and in turn. But you need something like mikrotik wrote in the logs:
ether18link up (speed 1G, Full duplex)
ether15link up (speed 100M, Full duplex)

Answer 1

use snmp: poll IF-MIB::ifTable with snmptable.

Answer 2

:foreach i in [/interface ethernet find] do={put ([/interface ethernet get $i value-name=name] ." ". [/interface ethernet get $i value-name=speed] ." full-duplex :".[/interface ethernet get $i value-name=full-duplex])}
