I have 2 SG500X switches, between master / backup switches I use a fiber cable connected on S3/S4 port (S3 on master, S4 on backup), the stacking mode used is "Native Stacking" (default configuration) in L2.
When I change my vlan configuration (like create a vlan and apply it to ports), it's been validated on the master but on the backup it stay on vlan 1 untagged.
I active the log in debug mode, but I don't see if there is any sync between master and backup.
Maybe I want to do is impossible, use my backup switch as backup, if my master die, my backup switch take the lead and network continue to work, My Esxi have 2 network cable in bonding so my VM can work on both.
Thanks for your help
