.. _ethernet-interface: ######## Ethernet ######## Configuration ############# Address ------- .. cfgcmd:: set interfaces ethernet address
Configure interface `` with one or more interface addresses. * **address** can be specified multiple times as IPv4 and/or IPv6 address, e.g. 192.0.2.1/24 and/or 2001:db8::1/64 * **dhcp** interface address is received by DHCP from a DHCP server on this segment. * **dhcpv6** interface address is received by DHCPv6 from a DHCPv6 server on this segment. Example: .. code-block:: none set interfaces ethernet eth0 address 192.0.2.1/24 set interfaces ethernet eth0 address 192.0.2.2/24 set interfaces ethernet eth0 address 2001:db8::ffff/64 set interfaces ethernet eth0 address 2001:db8:100::ffff/64 .. cfgcmd:: set interfaces ethernet ipv6 address autoconf .. include:: common-ipv6-addr-autoconf.txt .. cfgcmd:: set interfaces ethernet ipv6 address eui64 :abbr:`EUI-64 (64-Bit Extended Unique Identifier)` as specified in :rfc:`4291` allows a host to assign iteslf a unique 64-Bit IPv6 address. .. code-block:: none set interfaces ethernet eth0 ipv6 address eui64 2001:db8:beef::/64 Speed/Duplex ------------ .. cfgcmd:: set interfaces ethernet duplex 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 speed 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`. Link Administration ------------------- .. cfgcmd:: set interfaces ethernet description Assign given `` to interface. Description will also be passed to SNMP monitoring systems. .. cfgcmd:: set interfaces ethernet disable Disable given ``. It will be placed in administratively down (``A/D``) state. .. cfgcmd:: set interfaces ethernet disable-flow-control Disable Ethernet flow control (pause frames). .. cfgcmd:: set interfaces ethernet mac Configure user defined :abbr:`MAC (Media Access Control)` address on given ``. .. cfgcmd:: set interfaces ethernet mtu Configure :abbr:`MTU (Maximum Transmission Unit)` on given ``. It is the size (in bytes) of the largest ethernet frame sent on this link. Router Advertisements --------------------- Router advertisements are described in :rfc:`4861#section-4.6.2`. They are part of what is known as :abbr:`SLAAC (Stateless Address Autoconfiguration)`. .. cfgcmd:: set interfaces ethernet ipv6 router-advert send-advert Enable or disable router advertisements in this ``. .. cfgcmd:: set interfaces ethernet ipv6 router-advert prefix Prefix information is described in :rfc:`4861#section-4.6.2`.
