EtherChannel with LACP
Aggregate parallel links into one logical interface for cleaner redundancy and higher throughput.
Lab challenge
Replace awkward parallel links with a sane LACP-based port-channel that actually forwards.
Progression
Normalize member settings, build the channel group, move trunk settings to the logical interface, then verify bundle health.

Prerequisites
- • trunking basics
- • redundant links
Skills practiced
- • bundle interfaces with LACP
- • verify port-channel state
- • carry trunk settings consistently
Validation checklist
- • member links join the bundle
- • logical port-channel is up
- • trunk settings live on the bundle instead of per-member
Task sequence
- 1Prepare the physical links with matching settings.
- 2Create an LACP EtherChannel on both sides.
- 3Apply trunk configuration to the port-channel.
- 4Verify member state and bundle operation.
- 5Test traffic across the aggregated link.
