+
+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
