Etherchannel Configuration Example
Layer 3 Etherchannel
Spanning-Tree blocks redundant links and avoid Layer 2 loops. Etherchannels load balance the traffic between the redundadnt links and uses the bandwidth more efficient.
How can we configure etherchannel?
To understand more clear, here is a basic etherchannel configuration scenario:
Here, two switches connected by four cable from their gigabit ethernet ports. We will bundle four of the physical link into one logical link.
