ifconfig Commands To Configure, Monitor And Debug Network Interface
- inet (TCP/IP, default)
- inet6 (IPv6)
- ax25 (AMPR Packet Radio)
- ddp (Appletalk Phase 2)
- ipx (Novell IPX)
- netrom (AMPR Packet radio)
Advanced ifconfig Commands
Enable the promiscuous mode of the interface:
Most common ifconfig Commands
This command is the iproute equivalent to running ‘ifconfig’.
This parameter sets the interface metric.
This parameter sets the Maximum Transfer Unit (MTU) of an interface.
Set the remote IP address for a point-to-point link (such as PPP).
Set the IP network mask for this interface. This value defaults to the usual class A, B or C network mask (as derived from the interface IP address), but it can be set to any value.
Add an IPv6 address to an interface.
Remove an IPv6 address from an interface.
Create a new SIT (IPv6-in-IPv4) device, tunnelling to the given destination.
Set the interrupt line used by this device. Not all devices can dynamically change their IRQ setting.
Set the start address in I/O space for this device.
Set the start address for shared memory used by this device. Only a few devices need this.
Set the physical port or medium type to be used by the device. Not all devices can change this setting, and those that can vary in what values they support. Typical values for type are 10base2 (thin Ethernet), 10baseT (twisted-pair 10Mbps Ethernet), AUI (external transceiver) and so on. The special medium type of auto can be used to tell the driver to auto-sense the media.
If the address argument is given, set the protocol broadcast address for this interface. Otherwise, set (or clear) the IFF_BROADCAST flag for the interface.
hw class address
Set the hardware address of this interface, if the device driver supports this operation. The keyword must be followed by the name of the hardware class and the printable ASCII equivalent of the hardware address. Hardware classes currently supported include ether (Ethernet), ax25 (AMPR AX.25), ARCnet and netrom (AMPR NET/ROM).
Set the multicast flag on the interface. This should not normally be needed as the drivers set the flag correctly themselves.
The IP address to be assigned to this interface.
Set the length of the transmit queue of the device. It is useful to set this to small values for slower devices with a high latency (modem links, ISDN) to prevent fast bulk transfers from disturbing interactive traffic like telnet too much.
