Configuration
#############
Common interface configuration
------------------------------
.. cmdinclude:: ../_include/interface-common-with-dhcp.txt
:var0: ethernet
:var1: eth0
Speed/Duplex
------------
.. 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`.
Link Administration
-------------------
.. cfgcmd:: set interfaces ethernet <interface> description <description>
Assign given `<description>` to interface. Description will also be passed
to SNMP monitoring systems.
.. cfgcmd:: set interfaces ethernet <interface> disable
Disable given `<interface>`. It will be placed in administratively down
(``A/D``) state.
.. cfgcmd:: set interfaces ethernet <interface> disable-flow-control
Disable Ethernet flow control (pause frames).
.. cfgcmd:: set interfaces ethernet <interface> mac <mac-address>
Configure user defined :abbr:`MAC (Media Access Control)` address on given
`<interface>`.
.. cfgcmd:: set interfaces ethernet <interface> mtu <mtu>
Configure :abbr:`MTU (Maximum Transmission Unit)` on given `<interface>`. It
is the size (in bytes) of the largest ethernet frame sent on this link.
Prefix Delegation (DHCPv6-PD)
-----------------------------
VyOS 1.3 (equuleus) supports DHCPv6-PD. DHCPv6 Prefix Delegation is supported
by most ISPs who provide native IPv6 for consumers on fixed networks.
.. cfgcmd:: set interfaces ethernet <interface> dhcpv6-option pd <id> length <length>
Some ISPs by default only delegate a /64 prefix. To request for a specific
prefix size use this option to request for a bigger delegation for this pd
`<id>`. This value
is in the range from 32 - 64 so you could request up to /32 down to a /64
delegation.
Default value is 64.
.. cfgcmd:: set interfaces ethernet <interface> dhcpv6-option pd <id> interface <delegatee> address <address>
Specify the interface address used locally on the interfcae where the prefix
has been delegated to. ID must be a decimal integer.
It will be combined with the delegated prefix and the sla-id to form a complete
interface address. The default is to use the EUI-64 address of the interface.
Example:
Using ``<id>`` value 65535 will assign IPv6 address ``<prefix>::ffff`` to the
interface.
.. cfgcmd:: set interfaces ethernet <interface> dhcpv6-option pd <id> interface <delegatee> sla-id <id>
Specify the identifier value of the site-level aggregator (SLA) on the
interface. ID must be a decimal number greater then 0 which fits in the length
of SLA IDs (see below). For example, if ID is 1 and the client is delegated
an IPv6 prefix 2001:db8:ffff::/48, dhcp6c will combine the two values into a
single IPv6 prefix, 2001:db8:ffff:1::/64, and will configure the prefix on
the specified interface.
