Network Flapping and get connect and dis-connect regularly
Hi, I have design Leaf and Spine with VLTi and VLT domain by using S4148FE-ON switches. Everything is working fine but ESXI hosts side and even end devices have packet loss and it is happening regularly. it gets connect and disconnect frequently. I used port channel to connect for ESXI host. Could you please any one help to fix this issue. Thanks in Advance.

Hi,
What version of the OS are you running? Are all of the devices directly connected or are there other switches involved? Is spanning-tree enabled? Are there any errors in the logs?

You might want to try updating to 10.4.3. Are there any errors with show logging? Instead of show switchport access vlan 1, do switchport trunk allowed vlan 1. Page 197 https://downloads.dell.com/manuals/common/os10_enterprise-ug_en-us.pdf
