Summary

Sub-menu: /interface ethernet
Standards: IEEE 802.3


MikroTik RouterOS supports various types of Ethernet interfaces.

Properties


Property Description
arp (disabled | enabled | proxy-arp | reply-only; Default: enabled) Address Resolution Protocol mode
auto-negotiation (yes | no; Default: yes) When enabled, the interface "advertises" its maximum capabilities to achieve the best connection possible.
Note: Auto-negotiation must be disabled on both ends, otherwise Ethernets may not work properly.
Note2: Gigabit link cannot work with auto-negotiation disabled.
bandwidth (integer/integer; Default: unlimited/unlimited) Sets max rx/tx bandwidth that will be handled by an interface.
cable-setting (default | short | standard; Default: default) changes the cable length setting (only applicable to NS DP83815/6 cards)
disable-running-check (yes | no; Default: yes) Disable running check. If this value is set to 'no', the router automatically detects whether the NIC is connected with a device in the network or not.
full-duplex (yes | no; Default: yes) Defines whether the transmission of data appears in two directions simultaneously
l2mtu (integer; Default: ) Layer2 Maximum transmission unit. Read more>>
mac-address (MAC; Default: ) Media Access Control number of an interface.
master-port (name | none; Default: none) Sets switch group master interface
mdix-enable (yes | no; Default: ) Whether the MDI/X auto crosscable correction feature is enabled for the port
mtu (integer; Default: 1500) Layer3 Maximum transmission unit
name (string; Default: ) Name of an interface
speed (10Mbps | 100Mbps | 1Gbps; Default: max available) Sets the data transmission speed of the interface. By default, this value is the maximal data rate supported by the interface


Read-only properties

Property Description
running (yes | no) Whether interface is running. Note that some interface does not have running check and they are always reported as "running"
rx-1024-1518 (integer) Total count of received 1024 to 1518 byte packets
rx-128-255 (integer) Total count of received 128 to 255 byte packets
rx-1519-max (integer) Total count of received packets larger than 1519 bytes
rx-256-511 (integer) Total count of received 256 to 511 byte packets
rx-512-1023 (integer) Total count of received 512 to 1023 byte packets
rx-64 (integer) Total count of received 64 byte packets
rx-65-127 (integer) Total count of received 65 to 127 byte packets
rx-align-error (integer) Total count of received align error messages
rx-broadcast (integer) Total count of received broadcast packets
rx-bytes (integer) Total count of received bytes
rx-fcs-error (integer) Total count of received frames with incorrect checksum
rx-fragment (integer) Total count of received fragmented frames
rx-multicast (integer) Total count of received multicast packets
rx-overflow (integer)
rx-pause (integer) Amount of received pause frames
rx-runt (integer) Amount of received frames shorter than the minimum 64 bytes but with a valid CRC
rx-too-long (integer)

Menu specific commands

Property Description
blink ([id, name]) Blink Ethernet leds
monitor ([id, name]) Monitor ethernet status. Read more>>
reset-counters ([id, name]) Reset stats counters. Read more>>
reset-mac ([id, name]) Reset MAC address to manufacturers default.

Monitor

/interface ethernet monitor command prints out current link, rate and duplex status of an interface.

Properties:

Property Description
auto-negotiation (done | incomplete) Current auto negotiation status.
  • done-negotiation completed
  • incomplete-negotiation failed or not yet completed
default-cable-settings (short | standard) default cable length setting (only applicable to NS DP83815/6 cards)
  • short-support short cables
  • standard-support standard cables
full-duplex (yes | no) Whether transmission of data occurs in two directions simultaneously
rate (10Mbps | 100Mbps | 1Gbps) Actual data rate of the connection
status (link-ok | no-link | unknown) Current link status of an interface
  • link-ok-the card is connected to the network
  • no-link-the card is not connected to the network
  • unknown-the connection is not recognized (if the card does not report connection status)


Example output of ethernet status:

[admin@MikroTik] /interface ethernet> monitor ether1
            status: link-ok
  auto-negotiation: done
              rate: 1Gbps
       full-duplex: yes

Stats

RouterOS v3.22 introduces a new command:

/interface ethernet print stats

This command will display all kinds of other statistics if the interface is supporting them (currently only RB450G ether2-ether5, RB750 ether2-ether5, RB750G ether1-ether5 and also RB1100 ether1-ether10). Complete list of properties can be found in section above

For example, output of ethernet stats on RB450G:

[admin@MikroTik] /interface ethernet> print stats

Switch

Sub-menu: /interface ethernet switch

This submenu allows to configure certain RouterBoard switch chip feature. Read more >>.

PoE out

PoE out settings are only available on RouterBOARD devices that have this hardware feature present. Power-out status information is not available. The only visual clue is a red LED in addition to green Ethernet activity led.

Feature can be configured using setting in /interface ethernet menu, for example, turning poe-out on ether2 interface off:

/interface ethernet set ether2 poe-out=off
Icon-note.png

Note: PoE pit on interface will return to previous state it was when board was operational.


Icon-note.png

Note: PoE out is controlled separately from RouterOS and will return to state regardless of state of RouterOS on RouterBOARD


Possible configuration modes:

  • off - all detection and power is turned off for this port. It is safe setting and is default for all RouterBOARDs shipped
  • auto - board will attempt to detect if power can be applied on the port. For power-on to happen there should be resistance on spare pairs in range from 19kΩ to 26.5kΩ.
  • on - detection range is removed. As a result power over Ethernet will be turned on the port.
Icon-note.png

Note: Starting RouterOS 5.13 selection ON will turn power on the port no matter what is connected to the port. Check settings before you upgrade


When port is powered on

  • No detection if connected device can accept PoE is done;
  • When port is powered on - port overload and short detection is turned on;
  • If short is detected power on all ports will be turned on.
Icon-warn.png

Warning: If poe-out is set to on then power will be give on the port no matter what is connected on the port. That will burn non-poe capable ports
