This features will allow attributes to have aliases. Our use case today is between bond-slaves and bridge-ports, which be a little confusing. It follows the kernel api and existing linux tools. Bonding driver calls them slaves and to the bridge driver they are ports. With NCLU we we would like to be more consistent. We will now also support "bond-ports"a Ticket: CM-12763 Reviewed By: Roopa Testing Done: $ ifquery -a -c auto bond0 iface bond0 [pass] bond-slaves swp1 [pass] auto bond1 iface bond1 [pass] bond-ports swp2 [pass] root@cel-redxp-06:~# ifquery -a -r auto bond0 iface bond0 bond-lacp-bypass-allow 0 bond-slaves swp1 bond-mode 802.3ad bond-use-carrier 1 bond-lacp-rate 1 bond-min-links 1 bond-miimon 100 bond-xmit-hash-policy layer3+4 auto bond1 iface bond1 bond-lacp-bypass-allow 0 bond-slaves swp2 bond-mode 802.3ad bond-use-carrier 1 bond-lacp-rate 1 bond-min-links 1 bond-miimon 100 bond-xmit-hash-policy layer3+4 Signed-off-by: Julien Fortin <julien@cumulusnetworks.com>

python-ifupdown2 ================ This package is a replacement for the debian ifupdown package. It is ifupdown re-written in python. It maintains the original ifupdown pluggable architecture and extends it further. The python-ifupdown2 package provides the infrastructure for parsing /etc/network/interfaces file, loading, scheduling and state management of interfaces. It dynamically loads python modules from /usr/share/ifupdownmodules (provided by the python-ifupdown2-addons package). To remain compatible with other packages that depend on ifupdown, it also executes scripts under /etc/network/. To make the transition smoother, a python module under /usr/share/ifupdownmodules will override a script by the same name under /etc/network/. It publishes an interface object which is passed to all loadble python modules. For more details on adding a addon module, see the section on adding python modules. pluggable python modules: ========================= Unlike original ifupdown, all interface configuration is moved to external python modules. That includes inet, inet6 and dhcp configurations. A set of default modules are provided by the python-ifupdown2-addons deb. python-ifupdown2 expects a few things from the pluggable modules: - the module should implement a class by the same name - the interface object (class iface) and the operation to be performed is passed to the modules - the python addon class should provide a few methods: - run() : method to configure the interface. - get_ops() : must return a list of operations it supports. eg: 'pre-up', 'post-down' - get_dependent_ifacenames() : must return a list of interfaces the interface is dependent on. This is used to build the dependency list for sorting and executing interfaces in dependency order. - if the module supports -r option to ifquery, ie ability to construct the ifaceobj from running state, it can optionally implement the get_dependent_ifacenames_running() method, to return the list of dependent interfaces derived from running state of the interface. This is different from get_dependent_ifacenames() where the dependent interfaces are derived from the interfaces config file (provided by the user). Example: Address handling module /usr/share/ifupdownaddons/address.py build ===== - get source - install build dependencies: apt-get install python-stdeb apt-get install python-docutils - cd <python-ifupdown2 sourcedir> && ./build.sh (generates python-ifupdown2-<ver>.deb) install ======= - remove existing ifupdown package dpkg -r ifupdown - install python-ifupdown2 using `dpkg -i` - or install from deb dpkg -i python-ifupdown2-<ver>.deb - note that python-ifupdown2 requires python-ifupdown2-addons package to function. And python-ifupdown2-addons deb has an install dependency on python-ifupdown2
