From 9cd2d7a5a4fafadb65d772c48109d55d1e19d425 Mon Sep 17 00:00:00 2001 From: Steven Date: Wed, 20 Dec 2017 12:43:01 -0800 Subject: bond: Add bonding driver and LACP protocol Add bonding driver to support creation of bond interface which composes of multiple slave interfaces. The slave interfaces could be physical interfaces, or just any virtual interfaces. For example, memif interfaces. The syntax to create a bond interface is create bond mode To enslave an interface to the bond interface, enslave interface TenGigabitEthernet6/0/0 to BondEthernet0 Please see src/plugins/lacp/lacp_doc.md for more examples and additional options. LACP is a control plane protocol which manages and monitors the status of the slave interfaces. The protocol is part of 802.3ad standard. This patch implements LACPv1. LACPv2 is not supported. To enable LACP on the bond interface, specify "mode lacp" when the bond interface is created. The syntax to enslave a slave interface is the same as other bonding modes.
