π PORT CHANNEL / ETHERCHANNEL β HOW DOES IT WORK?
What happens when you connect multiple physical links between two switches? Instead of treating them as separate connections, Port Channel bundles them into a single logical link.
π Port Channel combines:
β’ Multiple physical interfaces β Gi0/1βGi0/4
β’ One logical interface β Po1
β’ Common technologies include LACP and EtherChannel
π Key Benefits:
β
Higher available bandwidth
β
Link redundancy
β
Load balancing
β
Better availability
β
Faster recovery when a member link fails
π‘ Simple concept:
Multiple Physical Links β Port Channel β One Logical Link
For example, four physical links can be grouped into Port Channel 1, allowing the switches to manage the bundle as a single logical connection.
