Most configuration tasks can be done on the EtherChannel interface instead of on each individual port, ensuring configuration consistency throughout the links.When STP blocks one of the redundant links, it blocks the entire EtherChannel.When several EtherChannel bundles exist between two switches, STP may block one of the bundles to prevent switching loops.o EtherChannel relies on existing switch ports.Where there is only one EtherChannel link, all physical links in the EtherChannel are active because STP sees only one (logical) link.

Most configuration tasks can be done on the EtherChannel interface instead of on each
individual port, ensuring configuration consistency throughout the links.
• EtherChannel relies on existing switch ports. There is no need to upgrade the link to a faster
and more expensive connection to have more bandwidth.
• Load balancing takes place between links that are part of the same EtherChannel.
• EtherChannel creates an aggregation that is seen as one logical link. When several
EtherChannel bundles exist between two switches, STP may block one of the bundles to
prevent switching loops. When STP blocks one of the redundant links, it blocks the entire
EtherChannel. This blocks all the ports belonging to that EtherChannel link. Where there is only
one EtherChannel link, all physical links in the EtherChannel are active because STP sees only
one (logical) link.
• EtherChannel provides redundancy because the overall link is seen as one logical connection.
Additionally, the loss of one physical link within the channel does not create a change in the
topology.
