IFRELOAD(8) IFRELOAD(8)

NAME

ifreload - reload network interface configuration

SYNOPSIS

ifreload [-h] (-a|-c) [-v] [-d] [-f] [-n] [-s]


DESCRIPTION

reloads network interfaces(5) file /etc/network/interfaces or config file defined in ifupdown2.conf file.

Runs ifdown on interfaces that were removed from the file and subsequently runs ifup on all interfaces.

ifreload is non-disruptive. It will fix running config to match what is configured in the interfaces file without bringing the interface down. There are some cases where on linux an interface config cannot be applied unless the interface is brought down...eg: change of mac address and a few bond attributes. For such attribute changes, it may flap the interface only if the linux kernel requires it to.

When removing an interface (iface section) from the interfaces file please make sure all its references are removed as well. Similarly when renaming an interface, please make sure all references to the interface are changed to the new name. Renaming an interface in the interfaces file results in ifdown of the old and ifup of the interface with the new name.

If you do not wish to execute down on any interfaces, but only up on interfaces that were already up, please see the --currently-up option below.



OPTIONS

-h, --help
show this help message and exit
-a, --all
process all interfaces marked "auto"
-v, --verbose
verbose
-d, --debug
output debug info
-f, --force
force run all operations
-c, --currently-up
Reload the configuration for all interfaces which are currently up regardless of whether an interface has "auto <interface>" configuration within the /etc/network/interfaces file.
-X EXCLUDEPATS, --exclude EXCLUDEPATS
Exclude interfaces from the list of interfaces to operate on. Can be specified multiple times If the excluded interface has dependent interfaces, (e.g. a bridge or a bond with multiple enslaved interfaces) then each dependent interface must be specified in order to be excluded.
-s, --syntax-check
Only run the interfaces file parser



EXAMPLES

# reload all auto interfaces in interfaces(5) file

ifreload -a

# reload all interfaces using service command

service networking reload

# reload all currently up interfaces without bringing any interfaces down

service networking reload-currently-up
