NAME
ifupdown-addons-interfaces - ifupdown2 addon modules interface configuration
DESCRIPTION
ifupdown2 addon modules add incremental functionality to core
ifupdown2 tool.
All installed addon modules are executed on every interface listed
in the interfaces file. Addon modules are installed under
/usr/share/ifupdownaddons. To see the list of active addon modules,
see ifaddon(8).
Addon modules add new attributes to the interfaces(5) file. Below
is a list of attribute options provided by each module. These can
be listed under each iface section in the interfaces(5) file.
EXAMPLES
Listed below are addon modules and their supported attributes. The
attributes if applicable go under the iface section in the
