ip link add
- add virtual link
link DEVICE
specifies the physical device to act operate on.
NAME specifies the name of the new virtual device.
TYPE specifies the type of the new device.
Link types:
vlan - 802.1q tagged virtual LAN interface
veth - Virtual ethernet interface
vcan - Virtual Local CAN interface
dummy - Dummy network interface
ifb - Intermediate Functional Block device
macvlan - virtual interface base on link layer address (MAC)
can - Controller Area Network interface
bridge - Ethernet Bridge device
ip link
delete - delete virtual link
DEVICE specifies the virtual device to act operate on.
TYPE specifies the type of the device.
dev DEVICE
specifies the physical device to act operate on.
ip link set
- change device attributes
dev DEVICE
DEVICE specifies network device to operate on. When configuring SR-IOV Virtual Fuction (VF) devices, this keyword should specify the associated Physical Function (PF) device.
group GROUP
GROUP has a dual role: If both group and dev are present, then move the device to the specified group. If only a group is specified, then the command operates on all devices in that group.
up and down
change the state of the device to UP or DOWN.
arp on or arp off
change the NOARP flag on the device.
multicast on or multicast off
change the MULTICAST flag on the device.
dynamic on or dynamic off
change the DYNAMIC flag on the device.
name NAME
change the name of the device. This operation is not recommended if the device is running or has some addresses already configured.
txqueuelen NUMBER
txqlen NUMBER
change the transmit queue length of the device.
mtu NUMBER
change the MTU of the device.
address LLADDRESS
change the station address of the interface.
broadcast
LLADDRESS
brd LLADDRESS
peer LLADDRESS
change the link layer broadcast address or the peer address when the interface is POINTOPOINT.
netns PID
move the device to the network namespace associated with the process PID.
netns NETNSNAME
move the device to the network namespace associated with name NETNSNAME.
alias NAME
give the device a symbolic name for easy reference.
group GROUP
specify the group the device belongs to. The available groups are listed in file /etc/iproute2/group.
|
vf NUM |
specify a Virtual Function device to be configured. The associated PF device must be specified using the dev parameter. |
mac LLADDRESS - change the station address for the specified VF. The vf parameter must be specified.
vlan VLANID - change the assigned VLAN for the specified VF. When specified, all traffic sent from the VF will be tagged with the specified VLAN ID. Incoming traffic will be filtered for the specified VLAN ID, and will have all VLAN tags stripped before being passed to the VF. Setting this parameter to 0 disables VLAN tagging and filtering. The vf parameter must be specified.
qos VLAN-QOS - assign VLAN QOS (priority) bits for the VLAN tag. When specified, all VLAN tags transmitted by the VF will include the specified priority bits in the VLAN tag. If not specified, the value is assumed to be 0. Both the vf and vlan parameters must be specified. Setting both vlan and qos as 0 disables VLAN tagging and filtering for the VF.
rate TXRATE - change the allowed transmit bandwidth, in Mbps, for the specified VF. Setting this parameter to 0 disables rate limiting. The vf parameter must be specified.
spoofchk on|off - turn packet spoof checking on or off for the specified VF.
master DEVICE
set master device of the device (enslave device).
nomaster
unset master device of the device (release device).
Warning: If multiple parameter changes are requested, ip aborts immediately after any of the changes have failed. This is the only case when ip can move the system to an unpredictable state. The solution is to avoid changing several parameters with one ip link set call.
ip link show
- display device attributes
dev NAME (default)
NAME specifies the network device to show. If this argument is omitted all devices in the default group are listed.
group GROUP
GROUP specifies what group of devices to show.
|
up |
only display running interfaces. |
ip link show
Shows the state of all network interfaces on the system.
ip link set dev ppp0 mtu 1400
Change the MTU the ppp0 device.
ip link add link eth0 name eth0.10 type vlan id 10
Creates a new vlan device eth0.10 on device eth0.
ip link delete dev eth0.10
Removes vlan device.
