.. _ethernet-interface:
########
Ethernet
########
This will be the most widely used interface on a router carrying traffic to the
real world.
*************
Configuration
*************
Common interface configuration
==============================
.. cmdinclude:: /_include/interface-common-with-dhcp.txt
:var0: ethernet
:var1: eth0
Ethernet options
================
.. cfgcmd:: set interfaces ethernet <interface> duplex <auto | full | half>
Configure physical interface duplex setting.
* auto - interface duplex setting is auto-negotiated
* full - always use full-duplex
* half - always use half-duplex
VyOS default will be `auto`.
.. cfgcmd:: set interfaces ethernet <interface> speed <auto | 10 | 100 | 1000 |
2500 | 5000 | 10000 | 25000 | 40000 | 50000 | 100000>
Configure physical interface speed setting.
* auto - interface speed is auto-negotiated
* 10 - 10 MBit/s
* 100 - 100 MBit/s
* 1000 - 1 GBit/s
* 2500 - 2.5 GBit/s
* 5000 - 5 GBit/s
* 10000 - 10 GBit/s
* 25000 - 25 GBit/s
* 40000 - 40 GBit/s
* 50000 - 50 GBit/s
* 100000 - 100 GBit/s
VyOS default will be `auto`.
.. cfgcmd:: set interfaces ethernet <interface> mirror <interface>
Use this command to mirror the inbound traffic from one Ethernet interface to
another interface. This feature is typically used to provide a copy of traffic
inbound on one interface to a system running a monitoring or IPS application
on another interface. The benefit of mirroring the traffic is that the
application is isolated from the source traffic and so application processing
does not affect the traffic or the system performance.
Example:
.. code-block:: none
set interfaces ethernet eth0 mirror eth1
