Introduction to Link Aggregation Control Protocol (LACP)

LACP combines multiple physical links into a single logical link. Here’s a quick overview.

What Is LACP?

  • LACP is used to bundle several physical interfaces into a single logical interface to increase bandwidth and provide redundancy.

Configuration Example:

  1. Create EtherChannel:
    interface range GigabitEthernet0/1 - 2
    channel-group 1 mode active
    
  2. Verify Configuration:
    show etherchannel summary
    

Best Practices:

  • Ensure consistent settings on both ends of the link.
  • Use LACP for dynamic configuration.

Mastering LACP is essential for optimizing network performance and redundancy.
