After that, it is usually only needed when debugging or when system tuning is needed. Ifconfig is used at boot time to set up interfaces as necessary. Interactive traffic like telnet too much. Latency (modem links, ISDN) to prevent fast bulk transfers from disturbing It is useful to set this to small values for slower devices with a high Txqueuelen length Set the length of the transmit queue of the device.
Ifconfig display for mac drivers#
The drivers set the flag correctly themselves.Īddress The IP address to be assigned to this interface. Multicast Set the multicast flag on the interface. Hardware classesĬurrently supported include ether (Ethernet), ax25 (AMPR AX.25), ARCnet and The keyword must be followed by the name of the hardware classĪnd the printable ASCII equivalent of the hardware address.
Ifconfig display for mac driver#
Hw class address Set the hardware address of this interface, if the device driver supports Otherwise, set or clear the IFF_POINTOPOINT flag for the interface.
Side of the link, just like the obsolete dstaddr keyword does. If the address argument is also given, set the protocol address of the other It is a direct link between two machines with nobody else listening on it. Pointopoint This keyword enables the point-to-point mode of an interface,meaning that
Otherwise, set (or clear) the IFF_BROADCAST flag for Again, not all drivers can do this.īroadcast If the address argument is given, set the protocol broadcast addressįor this interface. The special medium type of auto can be used to tell the driver to auto-sense the Typical values for type are 10base2 (thin Ethernet),ġ0baseT (twisted-pair 10Mbps Ethernet), AUI (external transceiver) and so on. Not all devices can change this setting, and those that can vary Media type Set the physical port or medium type to be used by the device. Mem_start addr Set the start address for shared memory used by this device. Io_addr addr Set the start address in I/O space for this device. Not all devices can dynamically change their IRQ setting.
Irq addr Set the interrupt line used by this device. Tunnel aa.bb.cc.dd Create a new SIT (IPv6-in-IPv4) device, tunnelling to the given destination. (as derived from the interface IP address), but it can be set to any value.Īdd addr/prefixlen Add an IPv6 address to an interface.ĭel addr/prefixlen Remove an IPv6 address from an interface. This value defaults to the usual class A, B or C network mask Netmask addr Set the IP network mask for this interface. etc/sysconfig/network-scripts/ifcfg-eth0 CentOS/RHEL/Fedoraĭstaddr addr Set the remote IP address for a point-to-point (PPP)link (obsolete use pointopoint instead) Mtu N Set the Maximum Transfer Unit (MTU) of an interface. If selected, all multicast packets on the network will be received by the interface. If selected, all packets on the network will be received by the interface.Īllmulti Enable or disable all-multicast mode. Promisc Enable or disable the promiscuous mode of the interface. It is implicitly specified if an address is assigned to the interface.ĭown This flag causes the driver for this interface to be shut down.Īrp Enable or disable the use of the ARP protocol on this interface. Up This flag causes the interface to be activated. Usually a driver name followed by a unit number, eth0 = 1st Ethernet interface. On most modern distributions ifconfig has been depracated, use ip instead.
