Linux LACP Bonding to Increase Throughput and Availability
Link Aggregation Control Protocol (LACP) is a method for creating ethernet port bonds, such that multiple network ports act and operate as a single logical port. There are a number of ways to create bonds, including statically configured “EtherChannels”. The problem with a static configuration though, is that if there’s a port failure, in this configuration you will continue to send some traffic into a blackhole. LACP periodically (either every 1 second or 30 seconds) sends control packets, which ensure that a port is passing traffic, and will be pulled out of the bond and failover traffic to remaining links.
