1
00:00:00.050 --> 00:00:08.550
Two Nexus leaf switches connect to the same access switch through a virtual port channel.

2
00:00:08.650 --> 00:00:15.650
The leaf switches use a peer link and a separate keepalive link.

3
00:00:20.500 --> 00:00:31.500
Check that the peer adjacency has formed and that both the peer link and the virtual port channel are up.

4
00:00:39.000 --> 00:00:46.500
On the access switch, one LACP bundle contains a link to each leaf.

5
00:00:53.400 --> 00:01:00.400
Ping between the hosts to confirm the starting path across VLAN ten.

6
00:01:10.200 --> 00:01:18.200
Shut down the access-facing link on leaf one and leave the peer link up.

7
00:01:18.950 --> 00:01:26.450
The local virtual port channel shows down while the peer link stays up.

8
00:01:33.350 --> 00:01:39.350
Ping again to check reachability through the remaining leaf link.

9
00:01:49.150 --> 00:01:56.650
Bring the disabled interface back up and confirm the virtual port channel recovers.

10
00:02:03.550 --> 00:02:11.550
Run one last ping to verify that the restored topology can still carry traffic.
