Bundle links and test a member failure

Connect two Cisco switches with two links, with a test host on each side.

Set switch two to passive mode so it waits for an active LACP peer.

Set both uplinks on switch one to active mode in the same channel group.

The summary shows port channel ten in use, with both physical ports bundled.

Reload the lab to see both links labeled as one port channel.

Ping across the bundle to confirm the starting path works.

Shut down one member interface to simulate a failed link.

Port channel ten stays in use with the other member still bundled.

Ping again to confirm the surviving link carries traffic.

Bring the disabled interface back up and confirm both members are bundled again.
