Network interfaces management

An interface that is “up” is available to your application for input and output, and “down” is the opposite state. Sign In Don’t have an account? Change the default gateway for a network interface. Set a network interface as the default network interface used to output all packets ,wip which no specific route is found More Contents [ show ].

The final parameter input is the function that a driver will call when it has received a new packet. Add a network interface to the list of lwIP netifs. The network interfaces are kept on a global linked list, which is linked by the next pointer in the structure.

Remove extended netif events listener Parameters callback pointer to listener structure. The user specifies an IP address for the interface, its net mask, and gateway address see IP stack for more details. Check your driver for more information. Set a network interface as the default network interface used to output all packets for which no specific route is found. The status callback will be called anytime the interface is brought up and down.

lwIP: Network interface (NETIF)

Returns netif, or NULL if failed. Set a network interface as the default network interface used to output all packets for which no specific route is found. Find a network interface by searching for its name.

When the IP stack tries to route the packet, if it cannot determine the right interface to use, it will send it to the default interface. Therefore, before you can use the interface, you must bring it up. Parameters netif a pre-allocated netif structure ipaddr IP address for the new netif netmask network mask for the new netif liwp default gateway IP address for the new netif state opaque data passed to the new netif init callback function that initializes the interface input callback function that is called to pass ingress packets up in the protocol layer stack.

In other words, the functions only work when the netif driver is implemented correctly!

This parameter typically takes one of the following values:. Add a network interface to the list of lwIP netifs. Set a network interface as the default network interface used to output all packets for which no specific route is found Parameters netif the default network interface. Parameters netif a pre-allocated netif structure ipaddr IP address for the new netif netmask network mask for the new netif gw default gateway IP address for the new netif state opaque data passed to the new netif init callback function that initializes the interface input callback function that is called to pass ingress packets up in the protocol layer stack.

Returns netif, or NULL if failed. Remove a network interface from the list of lwIP netifs.

This can be accomplished depending on how the interface gets its IP address. Change the IP address of a network interface. Parameters netif the network interface to remove. Change IP address configuration for a network interface including netmask and default gateway.

Parameters netif the network interface to remove References netif:: Bring an interface up, available for processing nstwork. Remove a network interface from the list of lwIP netifs.
