NAME
|
||||
----
|
||||
cdist-type__network_interface - configure network interfaces
|
||||
|
||||
|
||||
DESCRIPTION
|
||||
-----------
|
||||
Configures network interfaces on debian an redhat based systems.
|
||||
Interface names containing a dot are assumed to be vlan tagged sub interfaces.
|
||||
e.g. eth0.10 is vlan 10 on physical device eth0
|
||||
|
||||
|
||||
REQUIRED PARAMETERS
|
||||

||||
|
||||
|
||||
OPTIONAL PARAMETERS

||||
name::
|
||||
The name of the physical or logical network device.
|
||||
Defaults to __object_id.
|
||||
method::
|
||||

'dhcp', 'static' or 'manual'.
|
||||
Defaults to 'dhcp'.
|
||||
address::
|
||||
The IP address of the network interface.
|

additional config that is added to the generated interfaces file verbatim
|
||||
gateway::
|
||||
Default gateway (dotted quad)
|
||||
Only used if --method is not 'dhcp'
|
||||
netmask::
|
||||
The subnet mask to apply to the interface
|
||||
Only used if --method is not 'dhcp'
|
||||
metric::
|
||||
Routing metric for the default gateway
|
||||
mtu::
|
||||
The Maximum Transmission Unit size to use for the interface
|
||||
state::
|
||||
'present' or 'absent', defaults to 'present'
|
||||
bond-arp-interval::
|
||||
Specifies (in milliseconds) how often ARP monitoring occurs.
|
||||
bond-arp-ip-target::
|
||||
Specifies the target IP address of ARP requests when the arp_interval parameter is enabled.
|
||||
Can be specified up to 16 times.
|
||||
bond-master::
|
||||
The name of the master (bonding) interface to which this slave should be enslaved.
|
||||
bond-miimon::
|
||||
Specifies (in milliseconds) how often MII link monitoring occurs.
|
||||
bond-mode::
|
||||
Allows you to specify the bonding policy. The value can be one of:
|
||||
balance-rr (0)
|
||||
active-backup (1)
|
||||
balance-xor (2)
|
||||
broadcast (3)
|
||||
802.3ad (4)
|
||||
balance-tlb (5)
|
||||
balance-alb (6)
|
||||
bond-primary::
|
||||
Specifies the interface name, such as eth0, of the primary device.
|
||||
bond-slaves::
|
||||
The slave interfaces that form this bonding.
|
||||
linkdelay::
|
||||
Only useable on Redhat based systems.
|
||||
Time in seconds that the system should pause after the specific interface
|
||||
is enabled. This may be useful if one interface is connected to a
|
||||
switch which has spanning tree enabled and must wait for STP to
|
||||
converge before the interface should be considered usable.
|
||||
|
||||
|
||||
BOOLEAN PARAMETERS
|
||||
------------------
|
||||
onboot:
|
||||
Whether to bring the interface up on boot
|
||||
hotplug::
|
||||
Allow/disallow hotplug support for this interface
|
||||
nodns::
|
||||
Do not configure nameservers in /etc/resolv.conf.
|
||||
noroute::
|
||||
Do not set default route.
|
||||
no-network-wait-online::
|
||||
Do not consider this network interface in the network-wait-online.service unit.
|
||||
symmetric-routing::
|
||||
Manage routing tables and rules to ensure symmetric routing.
|
||||
