Runs on:

QNX OS

Description:

The ifconfig utility that QNX OS provides is ported from FreeBSD. You can use it to assign an address to a network interface, configure network interface parameters, or both.

QNX OS does not support the -j option for ifconfig.

For options and a detailed description, see the FreeBSD documentation (https://www.freebsd.org/cgi/man.cgi?query=ifconfig&sektion=8&manpath=FreeBSD+13.4-RELEASE+and+Ports).

The following ifconfig parameter has a limitation that is specific to io-sock:

prefixlen len
For io-sock, 0 is not a valid value for len. If you specify 0, ifconfig sets the value to 128.
Note:

When you specify an interface and down, it does not take the physical link down. If you specify ifconfig interface down, the status for the interface remains active.
