EtherChannels provide both greater capacity and increased redundancy between network and server infrastructure. There are few networks that can't take advantage of them.
- [Instructor] By default, in a switch network, … only a single connection between switches can be active … and forwarding traffic at the same time. … The alternate link will be blocked until the primary fails. … Then it has the opportunity to pass traffic. … This methodology is in place to prevent switching loops. … EtherChannel is an alternative that allows a switch … to simultaneously forward packets across redundant links. … EtherChannel can be referred to as link aggregation group … or bond depending on vendor and product. … The switch will create a logical interface … that is associated with all physical ports … that are part of the EtherChannel. … Within EtherChannel, if a link fails, … there is no STP convergence. … All remaining ports continue to forward traffic. … When a link returns, it will be added back … into the EtherChannel and can begin … forwarding traffic immediately. … Another benefit aside from resiliency, is link capacity. … If two gigabit interfaces are bonded, …
