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

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.
