VLT-break traffic fail scenario
Hi Community,
In our scenario we are testing some failover -redundancy test for application. we noticed when we break vlti link, traffic disturbed and get disturbance in traffic, we have not used downlink links in port channel, is it the reason for facing packet loss, I am not able to get understanding when vlti link fails at same time, how traffic flows.
please guide on this scenario.

Hi Community,
But as per practical scenario, if VLTi links cut down somehow, but Heartbit link not getting affected then traffic impacted, what is solution for that, if can guide in deep.
as Heartbit link manually cut is not practical.
Thanks.

Hello Thakar,
The manual cut of the Heartbeat is just to test.
Did you try these test from the link Joey supplied?
To perform VLT failover testing, follow the any one of the below steps : https://dell.to/3ZWiZO5
1. Shutdown VLT Port-channel on one of the peer.
2. Reboot one of the VLT peer.
3. Shutdown VLTi, VLT Port-channel and Management interface(or any interface used to reach VLT backup destination) on the VLT peer.
