MikroTik RouterOS supports various types of Ethernet interfaces.  
MikroTik RouterOS supports various types of Ethernet interfaces - ranging from 10Mbps to 10Gbps Ethernet over copper twisted pair, 1Gbps and 10Gbps SFP/SFP+ interfaces and 40Gbps QSFP interface. Certain RouterBoard devices are equipped with a combo interface that simultaneously contains two interface types (e.g. 1Gbps Ethernet over twisted pair and SFP interface) allowing to select the most suitable option or creating a physical link failover. Through RouterOS, it is possible to control different Ethernet related properties like link speed, auto-negotiation, duplex mode, etc, monitor a transceiver diagnostic information and see a wide range of Ethernet related statistics.

==Detect Cable Problems==
==Detect Cable Problems==


In RouterOS v6rc4 and newer releases there is the ability to detect problems with connected cables.
Cable test can detect problems or measure the approximate cable length if the cable is unplugged on the other end and there is therefore, "no-link".
Cable test can detect problems or measure the approximate cable length if the cable is unplugged on the other end and there is therefore, "no-link".
RouterOS will tell:
RouterOS will show:


* which cable pair is damaged
* which cable pair is damaged

In the above example, cable is not shorted but “open” at 4 meters distance, all cable pairs equally faulty at the same distance from the switch chip.

==Stats==
==Stats==
RouterOS v3.22 introduces a new command:
 
<pre>
Using <code>/interface ethernet print stats</code> command, it is possible to see a wide range of Ethernet related statistics. The list of statistics can differ between RouterBoard devices due to different Ethernet drivers. The list below contains all available counters across all RouterBoard devices. Most of the Ethernet statistics can be remotely monitored using [[Manual:SNMP | SNMP]] and MIKROTIK-MIB.
/interface ethernet print stats
 
</pre>
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 [[#Read-only_properties | section above]]<br />
<br />
<br />
For example, output of ethernet stats on RB450G:

Summary

Sub-menu: /interface ethernet
Standards: IEEE 802.3


MikroTik RouterOS supports various types of Ethernet interfaces - ranging from 10Mbps to 10Gbps Ethernet over copper twisted pair, 1Gbps and 10Gbps SFP/SFP+ interfaces and 40Gbps QSFP interface. Certain RouterBoard devices are equipped with a combo interface that simultaneously contains two interface types (e.g. 1Gbps Ethernet over twisted pair and SFP interface) allowing to select the most suitable option or creating a physical link failover. Through RouterOS, it is possible to control different Ethernet related properties like link speed, auto-negotiation, duplex mode, etc, monitor a transceiver diagnostic information and see a wide range of Ethernet related statistics.

Properties

Property Description
advertise (10M-full | 10M-half | 100M-full | 100M-half | 1000M-full | 1000M-half | 2500M-full | 5000M-full | 10000M-full; Default: ) Advertised speed and duplex modes for Ethernet interfaces over twisted pair, only applies when auto-negotiation is enabled. Advertising higher speeds than the actual interface supported speed will have no effect, multiple options are allowed.
arp (disabled | enabled | local-proxy-arp | proxy-arp | reply-only; Default: enabled) Address Resolution Protocol mode:
  • disabled - the interface will not use ARP
  • enabled - the interface will use ARP
  • local-proxy-arp - the router performs proxy ARP on the interface and sends replies to the same interface
  • proxy-arp - the router performs proxy ARP on the interface and sends replies to other interfaces
  • reply-only - the interface will only reply to requests originated from matching IP address/MAC address combinations which are entered as static entries in the ARP table. No dynamic entries will be automatically stored in the ARP table. Therefore for communications to be successful, a valid static entry must already exist.
auto-negotiation (yes | no; Default: yes) When enabled, the interface "advertises" its maximum capabilities to achieve the best connection possible.
  • Note1: Auto-negotiation should not be disabled on one end only, otherwise Ethernet Interfaces may not work properly.
  • Note2: Gigabit Ethernet and NBASE-T Ethernet links cannot work with auto-negotiation disabled.
bandwidth (integer/integer; Default: unlimited/unlimited) Sets max rx/tx bandwidth in kbps that will be handled by an interface. TX limit is supported on all Atheros switch-chip ports. RX limit is supported only on Atheros8327/QCA8337 switch-chip ports.
cable-setting (default | short | standard; Default: default) Changes the cable length setting (only applicable to NS DP83815/6 cards)
combo-mode (auto | copper | sfp; Default: auto) When auto mode is selected, the port that was first connected will establish the link. In case this link fails, the other port will try to establish a new link. In case of a reboot, any of the two ports can be running, it depends on which port will successfully establish the link first. When sfp mode is selected, the interface will only work through SFP/SFP+ cage. When copper mode is selected, the interface will only work through RJ45 Ethernet port.
comment (string; Default: ) Descriptive name of an item
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. Default value is 'yes' because older NICs do not support it. (only applicable to x86)
tx-flow-control (on | off | auto; Default: off) When set to on, the port will generate pause frames to the upstream device to temporarily stop the packet transmission. Pause frames are only generated when some routers output interface is congested and packets cannot be transmitted anymore. auto is the same as on except when auto-negotiation=yes flow control status is resolved by taking into account what other end advertises.
rx-flow-control (on | off | auto; Default: off) When set to on, the port will process received pause frames and suspend transmission if required. auto is the same as on except when auto-negotiation=yes flow control status is resolved by taking into account what other end advertises.
full-duplex (yes | no; Default: yes) Defines whether the transmission of data appears in two directions simultaneously, only applies when auto-negotiation is disabled.
l2mtu (integer [0..65536]; Default: ) Layer2 Maximum transmission unit. Read more>>
mac-address (MAC; Default: ) Media Access Control number of an interface.
master-port (name; Default: none) Outdated property, more details about this property can be found in the Master-port page.
mdix-enable (yes | no; Default: yes) Whether the MDI/X auto cross over cable correction feature is enabled for the port (Hardware specific, e.g. ether1 on RB500 can be set to yes/no. Fixed to 'yes' on other hardware.)
mtu (integer [0..65536]; Default: 1500) Layer3 Maximum transmission unit
name (string; Default: ) Name of an interface
orig-mac-address (read-only: MAC; Default: ) Original Media Access Control number of an interface.
poe-out (auto-on | forced-on | off; Default: off) Poe Out settings. Read more >>
poe-priority (integer [0..99]; Default: ) Poe Out settings. Read more >>
sfp-shutdown-temperature (integer; Default: 95) Temperature at which interface will be temporarily turned off due to too high detected SFP module temperature (introduced v6.48).
sfp-rate-select (high | low; Default: high) Allows to control rate select pin for SFP ports.
speed (10Mbps | 10Gbps | 100Mbps | 1Gbps; Default: ) Sets interface data transmission speed which takes effect only when auto-negotiation is disabled.

Detect Cable Problems

Cable test can detect problems or measure the approximate cable length if the cable is unplugged on the other end and there is therefore, "no-link". RouterOS will show:

  • which cable pair is damaged
  • the distance to the problem
  • how exactly the cable is broken - short-circuited or open-circuited

This also works if the other end is simply unplugged - in that case, the total cable length will be shown.

Here is example output: 

[admin@CCR] > interface ethernet cable-test ether2
         name: ether2
       status: no-link
  cable-pairs: open:4,open:4,open:4,open:4

In the above example, the cable is not shorted but “open” at 4 meters distance, all cable pairs equally faulty at the same distance from the switch chip.

Currently cable-test is implemented on the following devices:

  • CCR series devices
  • CRS1xx series devices
  • CRS2xx series devices
  • OmniTIK series devices
  • RB450G series devices
  • RB951 series devices
  • RB2011 series devices
  • RB4011 series devices
  • RB750Gr2
  • RB750UPr2
  • RB751U-2HnD
  • RB850Gx2
  • RB931-2nD
  • RB941-2nD
  • RB952Ui-5ac2nD
  • RB962UiGS-5HacT2HnT
  • RB1100AHx2
  • RB1100x4
  • RBD52G-5HacD2HnD
  • RBcAPGi-5acD2nD
  • RBmAP2n
  • RBmAP2nD
  • RBwsAP-5Hac2nD
  • RB3011UiAS-RM
  • RBMetal 2SHPn
  • RBDynaDishG-5HacD
  • RBLDFG-5acD
  • RBLHGG-5acD

Note: Currently cable-test is not supported on Combo ports.


Stats

Using /interface ethernet print stats command, it is possible to see a wide range of Ethernet related statistics. The list of statistics can differ between RouterBoard devices due to different Ethernet drivers. The list below contains all available counters across all RouterBoard devices.
