interface
RouterOS directory reference for /interface.
interface
Type: Directory
Interface list with counters and state. Each interface row counts its own packets and bytes; values beginning with fp show the Fast Path share of that traffic (streamlined CPU forwarding; HW-offloaded traffic shows in neither), and tx-queue-drop counts the packets dropped by the interface queue.
