2 hands-on Link Aggregation scenarios you build in your own Cisco Modeling Labs instance and grade against the answer key. Link Aggregation configuration and troubleshooting practice for CCNA and CCNP.
Hands-on CCNA EtherChannel repair lab. Two uplinks between a distribution and an access switch are intended to form a single port-channel trunk carrying VLAN 10. The starter ships with a real mode mismatch across the bundle and an allow-list error, so the Port-channel stays down and hosts cannot talk. Learners diagnose the symptom and standardize on one protocol family (PAgP, LACP, or Static) and correct trunking so VLAN 10 forwards end-to-end.
Build a two-link LACP EtherChannel between SW1 and SW2 using an active/passive pairing. The logical Port-channel2 carries VLAN 20 as an access link so two hosts on opposite switches can communicate. Verify with show etherchannel summary, show lacp neighbor, and host-to-host pings.
