MikroTik Ethernet Commands: Link, Errors and SFP Status
Read RouterOS Ethernet link speed, errors, traffic counters and SFP diagnostics with a focused command reference and an evidence-first workflow.
Read-only command: /interface/print
Inspect the RouterOS state behind a connectivity problem. These references cover physical links, bridge forwarding, IP routing, firewall connections and routing-protocol sessions. The examples target RouterOS v7 and identify hardware-dependent readings rather than assuming that every RouterBOARD, CRS or CHR exposes the same fields.
10 references
Read-only results link to an individual observation command. Other commands on the same page can have different effects.
No matching references. Try a task such as packet capture, route lookup, BGP or interface errors.
Choose the bridge reference for MAC learning and VLAN membership. Choose the route reference for active routes, routing tables and policy rules. Firewall counters and connection tracking help explain why a rule appears unused or why a connection keeps an earlier translation.
Torch and the packet sniffer are observation tools with performance and visibility consequences. Use their reference before treating an empty capture as proof of missing traffic. BGP, OSPF and IPsec each have separate state checks, so an established peer is not confused with a usable route or working protected data path.
Before making changes, read the backup, export and Safe Mode reference. For an existing symptom such as lost VLAN management, FastTrack bypass or WireGuard handshake without traffic, use the linked MikroTik troubleshooting guides alongside these command references.

Read-only command: /interface/print
Find a MAC address on a RouterOS bridge and inspect VLAN membership, PVID and hardware-offload state without changing the bridge configuration.
Read-only command: /interface/bridge/print detail
Inspect RouterOS v7 routes, next hops, custom tables and policy rules. Separate a missing route from selection of the wrong routing table.
Read-only command: /ip/route/print detail where dst-address=0.0.0.0/0
Inspect RouterOS firewall counters, NAT rules and connection tracking to follow one connection without flushing sessions or adding broad allow rules.
Read-only command: /ip/firewall/filter/print stats
Choose Torch or the RouterOS packet sniffer, filter one host or service, and understand NAT, hardware-offload and FastTrack visibility limits.
Read-only command: /tool/sniffer/print
Find RouterOS DHCP leases, check pool use and inspect delivered network settings. Separate server, client and relay questions before changing leases.
Read-only command: /ip/dhcp-server/print detail
Inspect RouterOS v7 BGP session state and one received prefix. Separate session establishment, route acceptance and next-hop selection.
Read-only command: /system/resource/print
Read RouterOS v7 OSPF neighbour states, interface templates and LSAs. Check adjacency and route installation as separate troubleshooting stages.
Read-only command: /routing/ospf/instance/print detail
Choose RouterOS binary backup or readable export, protect sensitive files and use Safe Mode for small remote changes without confusing it with a backup.
Read-only command: /system/identity/print
Inspect RouterOS IPsec IKE peers, matching policies and selected SA counters while avoiding session resets and accidental exposure of encryption keys.
Read-only command: /ip/ipsec/active-peers/print detail
